Title: Hydraulic rotating machine of swash plane type
Inventor: KOKUBU HARUO
IPC: F03C1/253
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To prevent abrasion, seize and the like from being generated on a sliding plane between a piston and a cylinder and a sliding plane between a swash plane and a shoe to improve performance of a hydraulic rotating machine. SOLUTION: A sulfurizing layer 23 is formed on the side of an outer periphery of a piston 21 and a sulfurizing layer 24 is formed on the side of a concave spherical part. Also, a sulfurizing layer 29 is formed on the side of convex spherical part 27A of a shoe 25. In addition, a sliding member 30 made of copper alloy and the like is provided on the rear side of the seating 26 of the shoe 25. Abrasion on sulfurizing layers 24, 29 generated on the sliding plane E between the piston 21 and the shoe 25 is minimized by making the sulfurizing layers 24, 29 thinner than the sulfurizing layer 23. Thereby, a worn fragment generated by these sulfurizing layers 24, 29 is prevented from coming into the sliding plane F between the swash plane 4 and the sliding member 30 via an oil passage 28 on the shoe side for a long period.

Title: Removal of oxidized metal film
Inventor: MAEJIMA SEIJIYU
IPC: B24C11/00
Filed: 1980-03-13
Abstract: PURPOSE: To prevent the occurrence of both physical and chemical problems on the surface of a treated metal by employing a metal the same in the type as the treated metal or a particle of an oxide thereof as blasting material when an oxidized metal film is peeled off.  
     CONSTITUTION: When a particle of a metal the same in the type as a treated metal or a particle of an oxide thereof is used in a single or mixed manner as blasting material, pieces of the metal impinging each other during the blasting don't cause any progress in corrosion, lowering in electric characteristics or other problems on  the surface of the treated metal even when left thereon or sticking thereinto. This is because there is no difference in the tendency of ionization between the two metals, which are the same in the type. The reason why the particles of the oxide are mixed is that the hardness and the strength can be increased in the surface treatment of a metal, for example, aluminum. Thus, this method can eliminate physical and chemical problems on the surface of the treated metal.
