Title: Closed-type scroll compressor
Inventor: SAKURAI KAZUO
IPC: F04C18/02
Filed: 1994-07-14
Abstract: PURPOSE:To efficiently separate lubricating oil contained in gaseous refrigerant by providing a passage system for gas to flow from a discharging port arranged in a closed container to the outside of a compressor after the gas discharged from a compression mechanism part passes an electric motor and flows toward the inner wall of the closed container. CONSTITUTION:When a driving shaft 7 is rotated by an electric motor 4, a turning scroll 5 is turned without making its self rotation, and the volume of a space is decreased while the space formed between the turning scroll and a fixed scroll is moved. Thereby, gas is sucked from a suction connection port 21 and compressed, and then discharged from the discharging hole 6d of the fixed scroll 6. In this case, the discharged gaseous refrigerant is allowed to flow into a gas passage 15 formed by an outer peripheral surface 8f of a frame 8 and the inner wall of a closed container 1, and made pass the electric motor 3, so as to cool it. After that, it is made pass a gas passage hole 16a bored on a cover 16 arranged on the lower part of the electric motor 3, so as to be made to collide with the inner wall of the closed container 1 facing it. Thereby, gaseous refrigerant is separated into lubricating oil and gas.

Title: Manufacture of fixing roller
Inventor: SUZUKI YUJI
IPC: B29L31/32
Filed: 1990-06-20
Abstract: PURPOSE:To prevent a parting line from being generated by coating the fixing roller with an elastic rubber material so that the external diameter of the roller coated with the elastic rubber material in an unvulcanized state has a specific relation with the external diameter of the roller after vulcanization and polishing. CONSTITUTION:A roller mandrel 20 which is made of aluminum, iron, copper, etc., is coated with the elastic rubber material across a primer to specific thickness to form an elastic rubber coating layer 30 in an unvulcanized state. The layer 30 needs to be thicker than the external diameter D after the polishing so as to satisfy 1.04D<=A<=1.12D, where A is the external diameter of the roller right after the roller is coated with the unvulcanized elastic rubber material and D is the finish external diameter of the roller after the vulcanization and polishing. When A is less than that, the effect to prevention against parting line generation after the manufacture of the fixing roller is small and when larger, the improvement of the effect can not be expected. Thus, the coating thickness of the unvulcanized elastic rubber material is set within the range to prevent the generation of the parting line almost completely.
