An ink-jet head has a passage component made of resin and a filter plate through which ink is filtered. The filter plate is fixed to the passage component and has a melting point higher than that of the passage component. The filter plate has an annular region and an inner region, and holes are formed through the filter plate in the annular and inner regions. The passage component has a filter support face that is in contact with the annular region but out of contact with the inner region. A holder is formed on the filter support face. The holder penetrates through at least one of the holes formed in the annular region and covers the other face of the filter plate.

A method of sealing a liquid container, including filling a liquid into a liquid-containing bag including a cylindrical inlet; and sandwiching the cylindrical inlet with a pair of heat-sealing heads by application of heat such that the cylindrical inlet is sealed with the liquid therein, wherein at least one of the pair of heat-sealing heads comprises a concave edge.

The present invention provides a method that allows ultra-precisely bonding by which a complete sealingly bonded molded article can be produced in a simple manner. This method includes (1) fixing an injection molded article (a) at a position (predetermined bonding position) formed with a mold; (2) mounting and moving a molded article (b) to be bonded to the injection molded article (a) to the predetermined bonding position within the mold; (3) positioning the molded article (b) at the predetermined bonding position ; and (4) closing the mold for bonding.

In reprocessed plastic material utilizing as a raw material thermoplastic molded part (12), a compatible sheet material (15) being stuck thereon, the weight of the sheet material (15) is made 0.5% or less of that of the molded part, and further the Izod impact strength and the melt flow rate of the reprocessed material are made, respectively, 80% or more and 120% or less of those of the virgin material. Thereby, good quality reprocessed plastic material with less degradation in physical properties and color relative to the virgin material is provided without adding a step other than a usually conducted recycling step, for recycling of a thermoplastic, a compatible label being stuck thereon.

Nonmetallic materials (18, 28) are welded without solder or adhesive by a laser (202) and preferably fiber optics (204) that direct laser light (220) through one of the materials (18) to create a seam weld. Through use of fiber optics the beam is optimally (Fig. 11) converted to heat, avoiding weld flaws due to underheating and material damage due to overheating. Welding is rapid and reproducible even for the smallest of contact geometries, achieving for example strong solderless gold-to-gold compression laser welding of a silicon substrate (28) to a polymeric (e. g. polyimide) flex circuit tape (18), without tape damage. The bond can be between a straight gold-bond line (210, Figs. 20-22[C]), or complex weld seam pattern (210, Figs. 17-19[C]), on the tape and a mating gold bond line or pattern (Figs. 17-22[A]) 208 on a semiconductor chip (28). In an inkjet printhead the result is to avoid delamination and nozzle skewing, associated in other methods with adhesive curing. Reduced skew provides less dot-placement error and thus better print quality. Better head configuration facilitates fixing a nozzle member to the substrate, and increasing nozzle area stiffness, nozzle camber angle and directionality, and substrate-to-tape bond strength-reducing deformation and so consistently raising ink refill speeds, and reducing ink trajectory errors and delamination. In particular embodiments, increased tolerance to aggressive solvents in inks, and more consistent chamber geometry, result in better drop-volume control, better pen quality, repeatability and reliability; and cutting down of process steps, processing time, cost, and in-process handling. These in turn provide ease of assembly, higher yields and reliability, ease of nozzle serviceability, and overall material and manufacturing cost reduction.

The supporting structure coverable with multiple concentric layers (3) of elastic silicone-based material to produce rollers (2) having a mirror-finished flexible outer surface has a hollow cylindrical body (6) and a surface that is affected by multiple openings (30) which are variously distributed and sized to allow the passage, produced by centrifugal force, of the material in the fluid/semifluid state from the inside towards the outer surface and to provide subsequent engagement.

A manufacturing method of a liquid jet head comprises the discharge ports for discharging the ink, the liquid channels in communication to the discharge ports, and energy generating means for generating the energy for use in discharging the ink. The method includes the steps of preparing a substrate having the energy generating means, preparing a resin ceiling plate fabricated by molding and having the grooves which constitute part of the liquid channels, positioning and contacting the ceiling plate on and with the substrate so that the grooves may be located above the energy generating means, and forming the liquid channels constituted of the grooves and the substrate by directing a laser beam from outside the ceiling plate in the state where the ceiling plate and the substrate are joined, to weld together the ceiling plate and the substrate.
