Title: Rotary compressor
Inventor: MATSUURA HIDEKI
IPC: F04B39/00
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To reduce sludge, which is generated in a slide part between a roller and a vane when an HFC-based refrigerant is used. SOLUTION: A vane 10 of a rotary compressor using an HFC-based refrigerant is formed such that an oxinitriding treatment and an oxidation treatment are applied onto a surface of a sintered metal. Thus, the surface of the sintered metal is hardened with the oxinitriding treatment, while it becomes porous with the oxidation treatment so that its holding property of a refrigerating machine oil is improved. A roller 8 is made of a cast iron. Moreover, polyvinyl ether oil is used as the refrigerating machine oil so that generation of a metal soap in a slide part between the roller 8 and the vane 10 is prevented. As a result, scuffing between the roller 8 and the vane 10 is reduced, generation of sludge (mainly the metal soap) between them is restrained, so that the rotary compressor and a refrigerating plant using it have improved reliability.

Title: Magnetic head for reading diskette
Inventor: SUNNHIYUN RII
IPC: G11B5/265
Filed: 1989-07-11
Abstract: PURPOSE: To provide an excellent performance magnetic head for reading a diskette by giving a reading function to an erase head and also preventing non-erase part from generating. CONSTITUTION: A middle part of a gap 3 of a erasing- and reading head 1 is formed by being arranged in parallel with the gap 4 of the recording head 2 in the same length w, and also both end parts of the gap 3 are open in the state of symmetrically bend at a prescribed angle of θ in the direction of the head 2. And when agreeing to a synchronizing signal SYNC, the head 1 is synchronized and moves to an address mark A/M and also starts detecting information recorded in disk tracks. Since, with this magnetic head, erasing and reading are performed by the head 1 and information recording by the head 2, erasing and recording information on a diskette can be done from the time when the head 1 detects the address mark A/M. Further, since the gap 3 for the head 1 is bent and extended to the head 2 side, non-erase part is not generated.

IPC: G11C29/04
Filed: 1988-07-15
Abstract: PURPOSE:To extend the life of a nonvolatile memory (NOVRAM) by detecting the value of a rewriting flag at the time of power source disconnection, and transferring data in a RAM part to a ROM part only when the RAM part is rewritten. CONSTITUTION:When a part of the memory area of a RAM part 10 is used as the rewriting flag, and the data in a ROM part 11 is transferred to the RAM part 10 by a re-call signal, and when the data in the RAM part 10 are newly rewritten from a control part 13, respectively different values are written to the rewriting flags, at the time of re-calling, the rewriting flags are all set at '0' and at the time of data writing, the rewriting flags are all set at '1'. At the time of the power source disconnection, the control part 13 detects the rewriting flags, and executes a storing action only when the flags are all at '1' (only when the data contents of the RAM part 10 is changed). Thus, the unnecessary storing action for the NOVRAM is eliminated, and its life can be extended.
