Title: Swash plate compressor
Inventor: MATSUDA MIKIO
IPC: F04B39/00
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To restrain a lowering of the life of a thrust bearing by decreasing load applied to the thrust bearing in a swash plate compressor. SOLUTION: In an operating chamber 38, a coolant sucked in an intake port 24 is compressed to the intermediate pressure, and in an operating chamber 39 formed on the external driving source side, the coolant compressed in the operating chamber 38 is sucked from a communicating passage 30 to be compressed to the discharge pressure. Thus, the axial load applied to a rotating shaft 5 due to a pressure difference between the internal pressure of a swash plate chamber 38a and the atmospheric pressure is substantially cancelled by the working force applied to a double-head piston 8 by the coolant in the operating chambers 38, 39.

IPC: G03F1/66
Filed: 1990-11-21
Abstract: PURPOSE:To prevent the contamination of a photomask and drop of the photomask by installing an adsorbing surface for adsorbing the surface of the photomask and an opening/closing valve for connecting the adsorbing surface and the atmosphere. CONSTITUTION:In a holding part 1, each sucker 5 is installed at four corners in the lower part, and a photomask is held by these suckers.

Title: Carbon fiber reinforced prepreg
Inventor: KOMADA HAJIME
IPC: B29B11/16
Filed: 1992-11-27
Abstract: PURPOSE:To obtain a prepreg having excellent impact absorbing property for obtaining a tennis racket to which only a little vibration will be transmitted at hitting a ball by burying in layer a resin film having damping property when a carbon fiber reinforced prepreg is manufactured. CONSTITUTION:Carbon fibers are wound on a drum being impregnate with epoxy resin, cut off, and taken out from the drum. The fibers are folded such that carbon fiber angles become constant. A prepreg can be made by inserting a damping film when the fibers are folded. For a resin film having high damping property, polyisobutylene, polyisobutylene-isoprene copolymer are preferable. When a resin, for example, polyoctenamer is mixed in those, they are pelletized without lowering the damping property so much, and the film can be molded. It is desirable to provide adhesive layers on both faces of the damping film. A frame of a tennis racket can be obtained by winding the prepreg on a core and heating it in a mold.
