81	Method of selectively forming an insulation layer	US736211	1985-05-20	US4595601A	1986-06-17	Keiji Horioka; Haruo Okano; Makoto Sekine
An insulation layer is selectively formed by exposing the surface of a workpiece to an atmosphere comprising a mixture of a halogen-based gas and a raw gas containing a compoundable element chemically bondable with an element of a material constituting surface layer of the workpiece to form an insulating compound. The surface layer of the workpiece is formed of a non-insulating material, such as a metallic material or a semiconductor material. Light rays are directly irradiated on the selected region or regions of the surface of the workpiece through the atmosphere of the gaseous mixture, thereby dissociating said halogen-based gas. As a result, a layer comprising the insulating compound is formed on the selected region of the surface of the workpiece on which the light rays have been directly irradiated.

A process for forming a pattern of conductive lines on the top of a multi-layer ceramic substrate comprising:providing a green ceramic substrate, embossing a pattern of grooves in the top surface of the green ceramic substrate,sintering the green ceramic substrate to thereby form a multi-layer ceramic substrate anddepositing a conductive material in at least a portion of said embossed pattern of grooves.
83	Method for palladium activating molybdenum metallized features on a ceramic substrate	US556732	1983-11-30	US4510000A	1985-04-09	Ananda H. Kumar; Bernard Schwartz
A molybdenum or tungsten metallurgical pattern is formed on or in a dielectric green sheet. Palladium, nickel, platinum or rhodium is coated on a layer of polyvinyl butyral which is carried on a polyester film. The metal layer of this assembly is laminated to a dielectric green sheet which carries the molybdenum or tungsten metallurgy. The polyester film is stripped off. The resulting assembly is sintered to a fired structure, whereby the polyvinyl butyral is volatilized off and the palladium, nickel, platinum or rhodium is alloyed with the molybdenum or tungsten metallurgy to provide a densified metallurgy whose surface is free of glass.
84	Method for depositing a uniform layer of particulate material on the surface of an article having interconnected porosity	US426364	1982-09-29	US4452832A	1984-06-05	George E. Wrenn, Jr.; John Lewis, Jr.
The invention is a method for depositing liquid-suspended particles on an immersed porous article characterized by interconnected porosity. In one form of the invention, coating is conducted in a vessel containing an organic liquid supporting a colloidal dispersion of graphite sized to lodge in surface pores of the article. The liquid comprises a first volatile component (e.g., acetone) and a second less-volatile component (e.g., toluene) containing a dissolved organic graphite-bonding agent. The liquid also contains an organic agent (e.g., cellulose gum) for maintaining the particles in suspension. A porous carbon article to be coated is immersed in the liquid so that it is permeated therewith. While the liquid is stirred to maintain a uniform blend, the vessel headspace is evacuated to effect flashing-off of the first component from the interior of the article. This causes particle-laden liquid exterior of the article to flow inwardly through its surface pores, lodging particles in these pores and forming a continuous graphite coating. The coated article is retrieved and heated to resin-bond the graphite. The method can be used to form a smooth, adherent, continuous coating of various materials on various porous articles. The method is rapid and reproducible.
85	Method of applying color relief decorations to ceramic and like products	US529658	1983-09-06	US4451307A	1984-05-29	Kurt Zimmer
A color decal is applied to the flat side of a relief image consisting of ceramic or like material in such a way that the color fields are adjacent to the flat side and are overlapped by a lacquer mask which contains frit and is separated from a paper carrier by a water-soluble film of glue or albumen. In order to apply the combined color and relief image to the surface of a ceramic or like object, the uneven side of the relief image is pressed against the surface of the object prior or subsequent to melting of the film so as to detach the carrier and expose the mask. In the next step, the images are treated by a squeegee or an analogous tool so as to partially deform the originally flat side of the relief image prior to sintering which entails evaporation of lacquer and conversion of frit into a glaze overlying the color fields which, in turn, overlie the uneven side of the relief image. The unevennesses of the side which contacts the surface of the object are completely transferred to the originally flat side in the course of the sintering operation.
86	Refractory structure and process for the preparation thereof	US411218	1982-08-25	US4436768A	1984-03-13	John L. Freeouf; William J. Haag; Jerry M. Woodall

Process for the production of a ceramic member having inclusions of electrically conductive material flush with its surface, wherein it comprises depositing on the bottom of a mould a small number of particles of said conductive material, placing above said particles the ceramic powder and compressing together the aggregate formed by the powder and the particles, followed by fritting at a temperature below the melting temperature of the conductive material.Cathode--solid electrolyte assembly obtained by using the above process.
88	Gas-discharge method for coating the interior of electrically non-conductive pipes	US240539	1981-03-04	US4349582A	1982-09-14	Hans Beerwald; Gunter Bohm; Gunter Glomski
A method for coating the interior of electrically non-conductive pipes by means of a reactive separation from a gas flowing through the pipe, whereby the gas is dissociated by an electrical gas discharge, and wherein the separation occurs simultaneously throughout the total pipe length. Pulse discharges are used having pulse lengths which are so adjusted to the transit time of the gas through the pipe that the time period between two successive pulses corresponds to the time which is required for filling the pipe with unused gas.
89	Method for increasing the strength of a porous body	US222088	1981-01-02	US4338353A	1982-07-06	Bernd Melchior
A method of treating a porous body to increase its strength and resistance to weathering that includes first removing gases and moisture from the porous body by applying a vacuum to a vessel containing the body, then filling the vessel with an impregnating liquid consisting of a hardenable (cureable) resin and hardner so that the body is completely immersed while the vacuum is being applied, then applying a positive pressure to the impregnating liquid in which the body is immersed until the impregnating liquid has penetrated into the porous body the desired amount, then draining the impregnating liquid from the vessel while maintaining the positive pressure and then initiating the hardening of the hardenable liquid while maintaining the positive pressure, part of the impregnating liquid on the surface of the body being removed prior to hardening of the impregnating liquid in the body.
90	Method for conditioning nitride surface	US195806	1980-10-10	US4330569A	1982-05-18	Michael R. Gulett; Murray L. Trudel; John K. Stewart, Jr.
A method of conditioning a nitride surface by treating it with ionized oxygen is disclosed. The nitride surface is placed in a vacuum and treated with the ionized oxygen for a period of time sufficient to condition the nitride for subsequent processing steps. The ionized oxygen treatment is performed substantially at ambient temperature. The conditioning method is included in a process for improving the adhesion characteristics of a photoresist film to a silicon nitride surface. A liquid solution of hexamethyldisilazane is applied to the conditioned nitride surface. Thereafter, a photoresist is applied, exposed through a photographic mask and developed in a known manner for the purpose of forming a photoresist masking film pattern. The photoresist film pattern typically serves as a mask during an etching process in which areas not covered by photoresist are removed by a suitable etching solution.
91	Apparatus for treating work pieces	US956656	1978-11-01	USRE30658E	1981-06-30	Karl E. Arvidsson
An apparatus for treating work pieces in a closed space having a collapsible material. The treatment utilizes a period of subpressure and a period of pressure, in which cavities in the pieces are more or less filled with liquid. Prior to this the cavities are wholly or partially filled with a surface-tension reducing gas and/or solution.
92	Tape product for forming indicia, and process and apparatus for producing same, and products produced using such tape product	US13210	1979-02-21	US4263085A	1981-04-21	Jon P. Ellis
A machine and process for forming indicia in or on the surface of objects, particularly friable or hyaline objects, such as glass and ceramics, by producing tape carrying indicia-forming masks, and for applying those masks to the articles to be engraved at a rapid rate, for relatively high volume applications, is disclosed. A die is formed by chemical etching, and is heated to cut an adhesive-backed thermoplastic film on a carrier tape. The masks and the cutout portions are separated, so that both positive and negative masks are produced simultaneously, and either can be applied automatically to objects to be etched and/or embossed. Embossing and/or etching is performed by sandblasting, chemical etching, or selective application of coating materials.
93	Pyrolytic gas method of coating graphitic or ceramic articles with solids	US934212	1978-08-16	US4262039A	1981-04-14	Erno Gyarmati; Hubertus Nickel; Ashok K. Gupta; Rudolf Munzer
A portion of the feed gas is supplied in a pulsating fashion to a fluidizeded reactor containing the articles to be coated mixed with fluidizing particles. The pulse frequency is between 1 and 10 Hz. A continuous flow of a portion of the total gas supply at a rate insufficient to produce turbulence in the bed is provided to facilitate control of the pulsing frequency and reduce the energy necessary for the pulsating gas stream. The gases fed to the reactor are a coating gas and a carrier gas, the flow containing the coating gas including a portion of the carrier gas. Either the pulsed flow or the continuous flow may consist entirely of carrier gas. The fluidizing particles are preferably of the same material as the articles to be coated and are typically of a grain size between 2 and 3 mm.
94	Electric resist wax pen	US974219	1978-12-28	US4218152A	1980-08-19	Leila C. Sloan
An electric hand-held resist pen with an improved font and holder is disclosed. The font holder includes arcuate prongs for slidably engaging the font. By sliding the font up and down in the font holder, the heat eminating from the resistance heat to the font to its contained materials is varied and, thus, the flow rate of the material from the pen is controlled.
95	Electric furnaces	US669970	1976-03-24	US4103099A	1978-07-25	Peter James Allsopp
Impregnation of a porous carbon body involving deposition of carbon from aas can be effected by establishing a thermal gradient across the body such that carbon is deposited at a boundary which advances through the body. The present furnace is for use in such a process and comprises a heater element with which, in use, the body is in contact and a cooled surface facing the element, characterized in that the latter surface is covered with a layer of thermal insulating material to reduce the thermal gradient across the body. This improves the economy of the process. The insulating material is suitably fibrous, eg graphite felt, and is protected by a layer of relatively low permeability, eg graphite sheet, to prevent deposition of carbon which would reduce its insulation properties.Such a furnace suitable for impregnating flat bodies, eg brake discs, comprises flat mutually parallel electrical heater elements connected electrically in series having water-cooled felt-covered panels located between them and outside the outermost elements.
96	Apparatus for vapor depositing pyrolytic carbon on porous sheets of carbon material	US642607	1975-12-19	US4048953A	1977-09-20	Robert W. Froberg
An elongated continuous porous sheet of fibrous carbon, such as paper of matted graphite fibers, woven graphite cloth or carbonized filter paper is longitudinally traversed through a reduced pressure heating zone (5mm. of Hg.) in which hydrocarbon gas is perpendicularly directed at relatively high velocities through restricted flow passages at the sheet, which is heated to a temperature of about 2200.degree. C. The flow passages are disposed in polycrystalline graphite guide plates forming a narrow slot through which the material passes. The gas flow cools the passages and prevents the hydrocarbon content from depositing out on and clogging them. The hydrocarbon gas impinges on the heated fibers and forms a deposit of pyrolytic carbon on them, which is heavier in back than in front. A pair of 13 mil. thick sheets are effectively infiltrated within a 40 mil. deep slot. The sheets are traversed at a speed of about 60 to 3600 feet per hour at a temperature of about 2000.degree. to 2400.degree. C at a pressure of from about 4 to 20 mm. Hg. A hydrocarbon gas at a flow rate of from about 5 to 20 c.f.m. effectively infiltrates the carbon sheet material and increases the sheet density by at least 20 grams per square meter. The velocity of the carbon depositing flow stream is maintained at from about 20 to 200 ft. per minute (STP).

99	Precision molded refractory articles and method of making	US41551073	1973-11-14	US3929476A	1975-12-30	KIRBY JR RUSSELL B; WING STEPHEN C
A precision molded refractory article, which can have an intricate geometry with fine surface detail, such as an electrical discharge machining electrode, is made by molding in a flexible mold a plastic mixture of multi-modal refractory powders and a thermoplastic binder to form a green article of predetermined shape and dimensions, heating the green article to remove said binder and consolidate the refractory powders with very minimum shrinkage of the article, infiltrating the resulting porous article or skeleton with a molten infiltrant of a low melting point metal or alloy, and cooling the infiltrated skeleton, thereby forming a precision refractory article having a uniform high density, a useful working surface free of machined or otherwise disturbed metal, and a shape and dimensions precisely conforming to said green article.
100	Fine-line thick-film substrate fabrication	US43606674	1974-01-24	US3876460A	1975-04-08	FLOCK WILLIAM M; COCHRAN LAWRENCE F
Ceramic substrates having screened and plated conductive lines 3 mils wide with 3 mil spacing are reliably produced by screening onto calcined but not sintered substrates, allowance being made for subsequent shrinkage on sintering to the fully cured state. In addition to better line definition, the process is simpler and more economic than methods currently employed.
