IPC: B32B27/04
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To prevent air from being swallowed, by dipping a printed circuit board where wetting property is given into thermosetting resin varnish, forming a thermosetting resin dipping coated film on the surface, and then performing heating and curing and forming an insulation layer made of thermosetting resin. SOLUTION: A printed circuit board, where the flat portion of a printed circuit board and recessed and projecting surfaces, the hole wall surface of through hole metal plating, or the like is wetted by the spray drop of an organic solvent, is dipped into the same liquid organic solvent to give wetting property. When the printed circuit board that becomes an inner-layer circuit is dipped into the thermosetting resin varnish, thermosetting resin varnish easily enters not only a flat surface but also the recessed and projecting surfaces for constituting a fine space and the wall surface of a through hole plating hole part. Then, when a dipped coated film is heated, thermosetting resin flows on melted softening and flows into the fine space, thus reducing the gathering of air in the fine space part.

Title: Production of ceramic extrusion molded accessory
Inventor: TAWARA HIDEO
IPC: C04B33/32
Filed: 1988-12-21
Abstract: PURPOSE:To provide an extrusion-molded ceramic accessory without producing any crack even in a sintering process by forming openings reaching a space portion thereof in the building-facing part of the calcined product of an extrusion-molded product for the ceramic accessory and subsequently sintering the opening-formed calcined product. CONSTITUTION:A raw material powder such as clay is kneaded with water and, if necessary, a thickening agent to prepare a raw material, which is extrusion-molded into a wet molded product, with e.g. a screw type extruder, and the wet molded product is dried and calcined. The building-facing part of the calcined product is provided with openings reaching the cavity thereof and subsequently sintered. The disposition of the openings permits that the central portion of the calcined product is communicated with the outside thereof, and hot air enters into the central portion to remarkably reduce the difference of the temperatures between the central portion and the peripheral portion thereof. Thereby, the method does not cause any dry contraction, produce the difference of the thermal expansion between the central and peripheral portions even on the sintering process and hence produce any crack.

Abstract: PURPOSE:To form a glazed surface having natural ruggedness by the simple method. CONSTITUTION:A ground coat 12 is applied on a tile body 10 and an over coat 14 of a m.p. higher than the m.p. of the ground coat 12 is applied on a part of this ground coat 12. The ground coat 12 melts and the over coat 14 floats by being partly in an eutectic state when such tile body is fired at the m.p. of the ground coat 12 or above when the tile body is cooled after the ground coat 12 nearly melts, the m.p. of the ground coat 12 part having the over coat 14 is increased by the eutectic and, therefore, the molten part solidifies from this part and the ground coat 12 part exposed on the outside surface solidifies last while shrinking on solidification. The parts of the over coat 14, therefore, constitute projecting parts and the parts of the ground coat 12 constitute recessed parts.
