Abstract: A lock including a lock bolt (12) equipped with a locking body (14) of cylindrical overall shape intended to be locked by snap-fitting into a locking orifice (16) of complementary shape made in a striker plate (18). The lock bolt (12) additionally includes an anti-hammer ring (76) surrounding a region of the locking body (14) which, when the lock bolt (12) is locked, is in contact with the periphery of the locking orifice (16). As a preference, the body (14) is equipped with a releasable snap-fitting mechanism including bearing limits (40) for axial bearing which are intended to interact with a first face (36) of the striker plate, and at least one retractable locking ball (42) intended to interact with a second face (38) of the striker plate. When the lock bolt (12) is locked, the anti-hammer ring (76) extends axially between the bearing elements (40) and the ball (42), lying adjacent to the first face (36) of the striker plate.

Abstract: An optical information reading apparatus comprises an optical integration circuit type pickup in which an optical waveguide for guiding light and a condensing coupler for condensing the guided light propagating within the optical waveguide are formed on an optical integration circuit substrate, sub-couplers for radiating a part of the injected light upon the information recording surface in the vicinity of a light spot formed by the optical pickup and subsidiary light detection elements for receiving reflection light of the light radiated from the sub-couplers reflected from the information recording surface. The sub-couplers and the subsidiary light detection elements are formed integrally with the optical pickup on the optical integration circuit substrate. Thereby the detection error can be reduced, it is not necessary to use attachment parts and therefore the apparatus can be integrated to thereby make it possible to minimize the size.

Abstract: A method and a device for obtaining plasma from a few microliters of blood for analysis purposes. The method makes use a transfer strip (10) and a turntable for performing centrifuging operations.

Abstract: A heat developable light-sensitive material comprising a support having provided thereon at least a light-sensitive silver halide, a binder, and a compound capable of ring-closure to produce a benzimidazole ring upon heat development can be developed to an increased maximum density with less fogging at a relatively low temperature in a short period of time.
