Title: Metal gasket
Inventor: UEDA KOSAKU
IPC: F16J15/08
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To improve durability of an engine by equalizing surface pressure around a cylinder bore for a long time. SOLUTION: In this metal gasket, a laminated portion 4 of a base plate 2 is formed on a periphery of a combustion chamber hole 3, while thickness of the laminated portion 4 exceeds the thickness of other portions. When the metal gasket is arranged between a connection surfaces of a cylinder block and a cylinder head followed by fastening by bolts, maximum load is applied to the laminated portion 4 for sealing the connection surfaces. The laminated portion 4 is prepared by bending back an end of the base plate 2 on the side of the combustion chamber hole 3. A metal shim plate 5 harder than the base plate 2 is fitted into a bent-back portion, whose contact area with the laminated portion 4 is varied along the circumferential direction of the combustion chamber hole 3. The laminated portion 4 is compressively molded in thickwise direction of the plate in such a state.  In addition, an entering amount of the shim plate 5 into the laminated portion 4 is varied by utilizing difference of stress due to difference of contact areas of the shim plate 5, at the time of compression. It is thus possible to vary thickness of the laminated portion along the circumference of the combustion chamber hole 3.

Title: Blind textile for electromagnetic wave shield
Inventor: SATO HIROSHI
IPC: H05K9/00
Filed: 1988-08-22
Abstract: PURPOSE:To shield electromagnetic waves given to an OA equipment, etc., by bonding a metallic thin-film worked film with a base fabric made of a flame- retardant fiber. CONSTITUTION:A film manufactured by thin-film working a metal or a metallic compound is attached while using a woven and knitted good made of flame- retardant fibers as a base fabric 4, thus preparing a blind foundation.

Filed: 1990-08-08
Abstract: PURPOSE:To prevent clogging of a reacting vessel with soot-like carbon and prolong continuous operating time by providing an oxygen-introducing port for oxidizing excess carbon on optical fiber and in the reaction vessel at a downstream side part performing carbon coating. CONSTITUTION:For instance, in forming a coating film by a heating CVD method, a hydrocarbon-based gas as a raw material is charged into a reaction vessel 2 together with an inert gas and pyrolytically decomposed at a high- temperature part in a furnace, then a part forms a carbon film having dense graphite structure on the surface of optical fiber 1 and on inner face of the vessel 2. Remaining carbon is downwardly flowed with a gas flow in the vessel 2 and oxidized by oxygen supplied from an oxygen-introducing port 4 installed at a position having a temperature of about 1000 deg.C in downstream side of the vessel 2 to be converted to CO2, then discharged from a lower port of the reaction vessel 2. In the process, although graphite-like carbon on the surface of the fiber 1 is also subjected to oxidation reaction, rate of oxidation is low and a small value in comparing to soot-like carbon.
