Title: Inter-tooth brush
Inventor: INABA OSAMU
IPC: A46B5/00
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To provide an inter-tooth brush on whose shaft any particularly large bending moment will never be applied and which is free from a risk of shaft breakage during the service by introducing such an arrangement that the shaft bends along the surface of a thin and long conical hole when a flexural stress acts on the shaft. SOLUTION: An inter-tooth brush concerned 1 is structured so that brush bristles are implanted in a shaft 3 consisting of a thin steel strand followed by a molding process so that a circular or conical shape is formed and this shaft 3 of steel wires is fixed to the tip of a shank 4 made of plastics, etc., wherein the shaft 3 is inserted through a hole 7 having a thin and long, irregular conical shape formed at one end of the shank 4, and that of the shaft ends opposite the brush 2 is fixed by means of hot press attachment. The end of the brush shaft 3 is folded in U-shape, and a rectangular hole is formed at one end of the shank 4 of the shaft accommodation part 9 where the u-shaped end 8 is put in. Accordingly no large flexural stress will act on the shaft 3, which is thus free from risk of breakage or slipping off.

Title: Torque limiting mechanism
Inventor: KUMOI KAZUNARI
IPC: F16H35/10
Filed: 1994-12-22
Abstract: PURPOSE: To provide a torque limiting mechanism having little rattle and constant cutoff torque and preventing the driven side from being freely rotated when the excess torque is cut off. CONSTITUTION: A ball 10 inserted into the hole of an inner rotor 2 is pressed by an outer rotor 5 by a spring 11, and a friction plate 13 engaged with the outer rotor 5 is pressed to an inner flange 1 by a disk spring 18. When excess torque is applied, the reaction force of the spring 11 is defeated, the ball 10 is pulled in, and the torque is cut off. Since the torque by friction is invariably applied between the friction plate 13 and the inner flange 1, the minimum torque required is invariably transmitted. This ball type torque limiting mechanism has little rattle, and it has an effect that the driven side is not rotated freely when torque is cut off.

Filed: 1989-12-12
Abstract: PURPOSE:To eliminate a projection on the side of a rear cover by arranging a magnetic head which records information on the magnetic storage part provided on the film by vertical magnetization on the photosensitive surface side of the film surface where there are projections of various arranged members. CONSTITUTION:A magnetic body 9 which is arranged on the rear cover side to form a magnetic path and the magnetic head 10 which is arranged on the side of a camera main body are arranged across the film 1. When information is read out of the magnetic storing part, a PNP transistor(TR) 16 and an NPN TR 17 are turned off and when a magnetized part comes onto the magnetic head 10, a voltage applied to the uninverted input terminal of a voltage comparator 14 becomes higher than a reference voltage inputted to its inverted input terminal, thereby inputting a signal to a microcomputer 15. The microcomputer 15 reads the input signal to read the information out. Thus, the magnetic head 10 is arranged on the photosensitive surface side of the film surface where various members such as a photographic lens are arranged and projections are already formed to eliminate projections on the rear cover side.

Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To eliminate such problems associated with the conventional processes for producing tannin of an insoluble or condensation type that intricate stages of gelatinizing tannic acid by adding aldehyde, sulfuric acid, phosphoric acid, etc., to a waste liquid or adding ammonia, aldehyde and sulfuric acid thereto and heating the waste liquid, etc., are need and the safe storage of the recovered harmful materials is difficult. SOLUTION: The tannic acid and gelatin are added to the waste liquid contg. org. materials, metals, heavy metals including osmium and other harmful materials by noticing that the tannic acid reacts with metals and gelatin and forms the complex of the macromolecules insoluble in water in the reaction with the gelatin. The complex including the org. materials, metals, etc., which are the materials to be removed is then settled by its own weight and the harmful materials included in the waste liquid are easily separated and recovered. Further, the recovered harmful materials are mixed with clay for pottery and the mixture is fired, by which the harmful materials are sealed into the pottery. The safe storage of the harmful materials is thus made possible.
