Title: Fingertip pulse wave sensor
Inventor: HASEBE NOBORU
IPC: A61B5/024
Filed: 1989-04-25
Granted: 1991-08-08
Abstract: A fingertip pulse wave sensor includes a fingertip cushion supporting member (10) having a fingertip cushion supporting surface (11), and a nail supporting member (20) having a nail supporting surface (21) which is disposed in opposed relationship with the fingertip cushion supporting surface (11) at an interval smaller than the standard thickness of fingertips (1). Either of the fingertip cushion supporting member or the nail supporting member (20) is fixed, and the other of the fingertip cushion supporting member (10) and the nail supporting member is hinged. The hinged fingertip cushion supporting member (10) or nail supporting member is urged in the direction in which they are moved to each other by an elastic body (30) which is capable of applying a substantially fixed amount of pressure with respect to the variations in the pivot stroke caused by the variations in the thickness of the fingertips (1) resting on the fingertip cushion supporting member (10). The fingertip pulse wave sensor also includes a light-emitting element (15) which is disposed on either of the fingertip cushion supporting surface (10) and the nail supporting surface, and a light-receiving element (26) which is disposed on the other of the fingertip cushion supporting surface and the nail supporting surface.

Title: Austenitic stainless steel screw and method for producing the same
Inventor: TAHARA MASAAKI
IPC: C23C8/26
Filed: 1991-04-23
Granted: 1995-01-13
Abstract: An austenitic stainless steel screw has a surface formed into a hard nitrided layer, and a part such as a screw head which is in contact with outside air has its ultra hard surface layer of the hard nitrided layer removed by scouring or the like, to be rust resistant. Even when the ultra hard surface layer is thus removed, an inner hard layer of the hard nitrided layer which was present beneath the surface layer remains to maintain the hardness of the screw surface. A method for manufacturing the austenitic stainless steel screw includes, upon forming the hard nitrided layer on the screw surface by nitriding, cleaning the austenitic stainless steel screw surface with a fluorine- or fluoride-containing gas prior to nitriding. Thereby, any remaining foreign matter or oxidized layer or the like on the screw surface is removed and at the same time the screw surface is activated so N atoms easily penetrate and diffuse during nitriding to form a uniform nitrided layer.

Title: Front loading driving device of magnetic recording/reproducing apparatus
Inventor: CHOE JONG-DON
IPC: G11B15/62
Filed: 1992-11-21
Granted: 1995-01-19
Abstract: The driver can drive the housing of the front-loading cassette tape by the driving power of the tape loading motor, and it can easily switch the driving power. The driver contains: a first power transfer gear which is fed from the loading motor; a transfer gear which conveys the housing of the front-loading cassette tape; a movable gear which is connected with the first power transfer gear to selectively transfer the power; a second power transfer gear to selectively supply the power of the first power transfer gear; a power switch gear to drive the second power transfer gear.

Title: Process for producing a nitrile resin having a good impact resistance
Inventor: KIM SUNG-KOOK
IPC: C08F279/04
Filed: 1992-11-24
Granted: 1996-01-09
Abstract: emulsion polymerising 10-30 wt.% the mixt. of unsatd. nitrile monomer and alkenyl aromatic hydrocarbon monomer; then opt continuously emulsion polymerising the residual unsatd. nitrile and alkenyl aromatic hydrocarbon in the condition of no more than 6% of the unsatd. nitrile among the producted polymer to termination of the polymerisation. The process is processed in the presence of rubber latex. The obtd. resin has excellent chemical resistance and good workability and impact resistance.
