IPC: G02B6/42
Filed: 1982-08-05
Abstract: PURPOSE:To obtain beams with high parallelism as light emerging from an end face of an optical fiber by pressing a heated convex body against the end face of the fiber contg. a thermoplastic resin as the core material to form a concave end face and joining a transparent body having a convex surface to the concave end face. CONSTITUTION:An optical fiber 1 contg. polymethyl methacrylate as the core material is inserted into a connector 2, and a convex body 4 of glass, poreclain, metal or the like is heated, pressed against an end face of the fiber 1, cooled, and detached to form a concave end face. The body 4 is preferably spherical. Light emeging from the concave end face of the fiber 1 is less extended than light emerging from a flat end face. A convex body corresponding to the concave end face such as a spherical lens is fixed in the concave end face with an adhesive 5 to obtain emergent light close to parallel beams. About half of the lens is inserted into the concave end face. A heated transparent spherical lens may be directly joined to a flat end face of the fiber 1 by press bonding.

Abstract: PURPOSE:To provide a food container which is not deformed at the time of usage, and can be easily discarded after the usage by forming the container body of a polyolefin resin film which contains a large quantity of a mineral filler. CONSTITUTION:A container A which is used as a container of fermented soybeans, etc., is formed of a film with a thickness of 300mu -1000mu, which is formed using a material consisting of a polyolefin resin containing 40-60% of a mineral filler, by vacuum molding or compression vacuum molding. Thus, a resin in which a large quantity of a mineral filler is contained has a heating value at the time of burning, which is close to that of paper. Also, since all the thermal decomposition products of polyolefin resins are lower hydrocarbons, they do not generate a noxious gas which is connected to the atmospheric contamination due to be burning. In addition, even when the container has a large thickness, it is comparatively easy to be smashed, and can be crushed, and the discarding of which can be easily performed.

Title: Magnetic toner developing device
Inventor: TOODA TOSHIO
IPC: G03G15/09
Filed: 1983-07-27
Abstract: PURPOSE:To separate easily two-component toners for development intruded into a one-component magnetic toner developing device and to prevent mixing of printing colors by sticking the two-component toners for development to a conductive member by the electric field between a sleeve and the conductive member. CONSTITUTION:A toner of the 1st color sticks to a metallic roller 33 by the electric field between the roller 33 and a sleeve 32 when the toner of the 1st color used in a two-component magnetic bruch developing device intrudes into a one-component magnetic toner developing brush 34. The one-component magnetic toner receives the stronger force of the magnetic force from a magnetic roller 31 than the force that the toner receives from the magnetic field between said two members and the toner hardly sticks to the roller 33. The toner on the roller 33 is taken by a scraping plate 35 and is housed into the vessel 36 of a partition plate 36. The toner of the 1st color is thus easily recovered and is prevented from being mixed with the one-component magnetic toner, by which the mixing of both colors is prevented.
