Title: Shoe for swash plate type compressor
Inventor: GARAI YOSHIHIRO
IPC: F04B27/08
Filed: 1980-03-31
Abstract: PURPOSE: To assemble easily as well as miniaturize a swash plate type compressor and further minimize its horsepower consumption, by forming a hemisphere part in a shoe and bringing it in sliding contact with a spherical depressed part of a piston.  
     CONSTITUTION: A shoe 15 consists of a hemisphere part 15a which is engaged and brought in sliding contact with a spherical depressed part 10b of a piston 10, a column part 15b next to the hemisphere part and a backing metal 16 fitted to the bottom of the column part. The bottom outer side of the backing metal can slide on an edge face 5a of a swash plate 5. A hole 17 with an internal diameter at its opening part shorter than that of the bottom is formed in the shoe 15 and filled with  fillers such as a felt and the like. Since consumption of horsepower is minimized  due to two sliding portions, one between the swash plate 5 and the shoe 15 and the  other between the shoe 15 and the piston 10, the length of the compressor in axial  direction may be shortened by reducing the gap between the shoe 15 and the  spherical depressed part 10b. Utilization of the fillers 18 containing lubricant improves sliding conditions.

Title: Optical recording medium and its formation method
Inventor: KUBOTA TAKESHI
IPC: G11B7/254
Filed: 1995-03-02
Abstract: PURPOSE: To obtain an optical recording medium which has an excellent abrasion resistance and prevents a warp or a crack due to a bend. CONSTITUTION: In an optical recording medium which is overlaid with a hardened layer 6 by a hardening resin on a transparent protective layer 1, the hardness of the hardened layer 6 is made continuously high from the interface toward the surface of the transparent protective layer 1. When the hardened layer 6 is to be formed, a plurality of hardening resins whose coefficients of hardening contraction are different are supplied simultaneously so as to be overlapped in a state that their coefficient of hardening contraction becomes large from the interface toward the surface of the transparent protective layer 1, and the resins are then hardened collectively.  A layer whose hardness is high (whose coefficient of hardening contraction is large) exists at the outside, and a layer whose hardness is low (whose coefficient of hardening contraction is small) exists at the inside, no interface exists between the layers, and the layers are in a continued state. As a result, it is possible to obtain the optical recording medium in which a warp does not exist as a whole, whose bending fitness is excellent and whose abrasion resistance is excellent.
