Title: Optical waveguide
Inventor: YONEDA ISAO
IPC: G02B6/42
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a waveguide without complexing the mounting form and also without increasing the cost required for optical axial adjustment, by forming a V groove on the substrate surface, forming light reflection films reflecting light on both ends of the V groove and mounting an optical fiber in the V groove. SOLUTION: The V groove 2 is formed on a silicon substrate 1, and the core wire of the optical fiber 4 cut to a length mountable into the V groove 2 is mounted. The light reflection films 3 made of gold with a high reflectance are formed on the slopes of the V groove 2 opposite to both side end surfaces of the optical fiber 4. The material constituting the light reflection film 3 is constituted so that a chromium thin film is formed on the silicon for improving adhesiveness, and a gold thin film with high reflectance is formed on it. Electrode pads 5 are formed on the surface in the periphery of the optical reflection film 3.  By such a structure, since the light is bent by the optical reflection films 3, when the optical fiber 4 is coupled with a light emitting/receiving element of a surface light emission type or a surface incident type, an optical semiconductor element is mounted precisely directly just above the optical reflection film 3 turning a light emitting surface of a light receiving surface upside down on the same substrate.

Title: Molding method for seat skin member and skin member
Inventor: YAGISHITA NORIO
IPC: B68G7/06
Filed: 1988-12-24
Abstract: PURPOSE:To prevent a skin member from being wrinckled and the like by arranging either one of a skin consisting of a skin member and wadding in a molding tool so as to be molded into a desired curved surface, and thereby consequently joining the other one together along the curved surface of the aforesaid one. CONSTITUTION:A skin member is formed by joining a skin 11 to wadding 12. The skin 11 is arranged on the molding surface 22 of a vacuum molding tool 21 so that the skin 11 is formed with a curved surface 11a along the molding surface 22 by means of evacuation. In the second place, adhesives 18 are applied to the joining surface of the wadding 12 so that the wadding 12 is arranged along the curved surface 11a of the skin 11 so as to be joined. The skin member is therefore formed with the curved surface at the time when the skin 11 is joined to the wadding 12, the skin member can thereby be formed into a desired curved surface with no wrinckle, no change in material and no damage to the member accompanied.

Inventor: FUJII EIJI
IPC: F24F5/00
Filed: 1989-12-20
Abstract: PURPOSE:To increase the refrigerant supply pressure and temperature to heat transfer tubes in a heat storage tank so as to increase the temperature difference between the refrigerant and heat storage medium during heat exchange and improve the cooling performance by providing an auxiliary compressor which pressurize a portion of refrigerant gas and supplies it to the heat storage tank. CONSTITUTION:The refrigerant is pressurized by a refrigerant pump 17 and an auxiliary compressor 25 up to the same pressure as the refrigerant passing through a main compressor 2, so that a pressure reducing valve, etc. become unnecessary. And, as the refrigerant is pressurized by the auxiliary compressor 25 before entering the refrigerant pump 27 and the degree of supercooling at the inlet of the pump is improved, the risk of cavitation is avoided. In conventional apparatus, a pressure reducing valve, a mixing tank and a level control valve, etc. for gas separation are required because the refrigerant led to and pressurized by the main compressor 2 has a higher pressure than the refrigerant pressurized by the pump 17, and the pressure of the refrigerant from the main compressor is reduced to join and mix both refrigerants together.

Filed: 1987-12-24
Abstract: PURPOSE:To obtain optical parts for necessitating no mount nor painting for interrupting an unnecessary light beam by forming a part for necessitating to interrupt a light beam on the surface of the optical parts to a rough surface. CONSTITUTION:A lens 1 is constituted of an effective surface 2, a flat part 3, an intermediate part 4 provided on an intermediate part and an edge 5. Also, the effective surface 2 is brought to specular working, and the intermediate part 4 is formed to a rough surface. At the time of forming the rough surface, in case of polishing an edge 8 by a grindstone in a conventional decentering process, a deformed grindstone is used instead of a conventional grindstone, and by polishing the surface of the lens of the outside of the effective diameter simultaneously with decentering, the rough surface is formed. As a result, a light beam which has been made incident on the outside of the effective diameter is scattered, therefore, the influence is scarcely exerted on an image forming point, and accordingly, the lens for necessitating no mount nor painting for interrupting an unnecessary light beam can be obtained.
