| 13 | Method for polishing a diamond or carbon nitride film by reaction with oxygen transported to the film through a superionic conductor in contact with the film | US478532 | 1995-06-07 | US5795653A | 1998-08-18 | Jerome J. Cuomo; Joseph E. Yehoda |
| A process and apparatus for polishing diamond or carbon nitride. A reaction and polishing take place at the interface between an oxygen superionic conductor (yittria-stabilized zirconia) and the diamond or carbon nitride. Oxygen anions are transported to the interface under the influence of a chemical gradient and react with the diamond or carbon nitride. Other mechanisms, such as an electric field and/or heat, that increase the partial pressure of oxygen on the opposing side of the interface of reaction can be used to accelerate the reaction time. The process may be undertaken at low temperatures and without mechanical motion, making it an attractive and useful polishing method. In addition, there is no residue of the polishing process which needs to be removed and polishing can be accomplished in ambient air. | ||||||

| PURPOSE:To make the smoothening of the surfaces of a disk after working unnecessary by compression-molding ceramics or sintered metal into a substrate having a prescribed shape for a recording medium. CONSTITUTION:The cope 2 and the drag 3 of a metallic mold 1 have inner spiral grooves 7, 8, respectively. Steam or water is introduced from the inside inlets 9 of the grooves 7, 8, and it is discharged from the outside outlets 10. Alumina powder is kneaded with polyvinyl butyral and an adequate amount of an org. solvent, and the kneaded material is dried to obtain ceramic powder. This powder is filled into the cavity 4 in the mold 1, and it is compression- molded into a disk using the resin covering the alumina powder as a binder. The mold 1 is heated so as to allow the resin to act well as the binder during the pressing. Immediately before finishing the pressing, the mold 1 is cooled, and the strength is increased by sintering. A substrate having flat surfaces is obtd. | ||||||

| PURPOSE:To prolong the life by using an org. solvent having power of partially dissolving the surface of a plastic substrate as one component of radiation-curing lacquer to maintain the adhesive strength of a layer of the lacquer having formed signal pits to the substrate. CONSTITUTION:An org. solvent having power of dissolving a plastic substrate is used as one component of radiation-curing lacquer. Mono-, di- or triester of acrylic acid or methacrylic acid is used as a radiation-curing compound. Electron beams, gamma-rays or ultraviolet rays are used as a radiation source. When ultraviolet rays are used, it is required to add a photopolymn. initiator such as benzoin isobutyl ether or benzoin isopropyl ether to the lacquer. The plastic substrate is made of polymethyl methacrylate, polycarbonate, a vinyl chloride-vinyl acetate copolymer or the like. | ||||||
