Title: Fingerprint collating device
Inventor: EGUCHI OSAMU
IPC: A61B5/117
Filed: 1988-04-12
Abstract: PURPOSE:To execute the collation of a fingerprint with a simple constitution by providing a picture processing part, which detects the optical condition of a finger depressing surface and detects the fingerprint, and a finger direction guide member to be protruded from the depressing surface. CONSTITUTION:An arithmetic part 23 emits a light emitting device 21 synchronizing with the image pickup period of a light receiving device 22. A light to be emitted from the light emitting device 21 is incident on the depressing surface 11 of a prism 1. Then, the light is wholly reflected in the recessed part of a fingerprint part 41 in a finger 4 and partially reflected in the projecting part of the part 41. The light receiving part 22 receives the light to be reflected from the depressing surface 11 and converts the light to a video signal. This video signal is primary picture-processed by the arithmetic part 23, which is composed of a microcomputer, and a fingerprint pattern signal is extracted. This fingerprint pattern signal is compared with a fingerprint pattern signal for referring of a specified person to be stored in advance and discriminated. Then, since a horseshoe-shaped barrier part 30 is installed in the edge part of the depressing surface 11 as a stopper member in order to specify the edge position of the finger 4, the finger 4 can be prevented from being dislocated in a longitudinal direction.

Title: Method for sintering operation
Inventor: FUJIHIRA KOICHI
IPC: F27B21/08
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently operate a magnetic field to a sintered ore by installing an attracting magnet at the upper part of the ore oppositely to the surface layer of the ore from the position for igniting a sintered ore material to the position for discharging the ore, thereby reducing the diffusion of the field to a pallet of ferromagnetic material. SOLUTION: A pallet 9 endlessly coupled to convey sintered ore has a grate formed of nonmagnetic material, a grate bar, a sidewall, and electromagnets Mi (Ma to Me) from the position 50 for igniting the surface layer of the material to a sintered ore discharging position (ore discharging) oppositely to the surface layer of the ore 10 generated on the pallet 9. The more sintered up to the arrival at the ore discharging position is dropped from the pallet 9 when the pallet 9 is rotated down. In this case, the air permeability of the material layer is improved by magnetically levitating the ore by the electromagnet Mi on a route for proceeding the combustion from the surface layer to the lower layer of the material on the pallet 9 to improve the combustion efficiency.

IPC: H02M3/28
Filed: 1988-04-14
Abstract: PURPOSE:To reduce a switching noise in high efficiency by inserting a current transformer in series with a feedback diode to detect a feedback current, and turning OFF a switching element after a resonance current completely becomes zero. CONSTITUTION:A series resonance converter has a DC power source 1, feedback diodes 2-3, switching elements 4-5, a transformer 6, resonance capacitors 7-8, an inductor 9, rectifying diodes 10-11, and a smoothing capacitor 12, and supplies a current to a load resistor 13.

Title: Valve device
Inventor: OKANO MASATOSHI
IPC: F16K1/22
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To provide a valve seat in which a high level difficult work is not required and a superior sealing durability is maintained for a long period of time. SOLUTION: As a rod 4 is rotated around a turning center 01 from its full closed state in a direction Q, an eccentric section 4a is rotated in a deflected state in such a way that its axis center 02 may be moved in an arcuate manner around the turning center. With such an arrangement as above, a valve element 3 is separated from a seat ring 2. As the rod is further rotated in the direction Q, a notch 4c is engaged with a stepped key 5 and the valve element is integrally rotated together with the rod. In turn, as the rod is rotated from its full- closed state in a direction S, the valve element is integrally rotated together with the rod. However, after the valve element is abutted against a full-closed stopper section 1b, the valve element is not rotated even when the rod continues to rotate.  After this operation, as the rod is further rotated in the direction S, the eccentric section 4a rotates in an eccentric manner while pushing up a stepped key 5 against a spring 6 and then the valve element is moved towards the seat ring.
