Abstract:
PURPOSE: To improve productivity and to reduce the defective ratio of products by using optical fibers for warp or woof to weave textile and arraying the optical fibers like a reed screen. CONSTITUTION: The optical fibers 1 are used as warp and normal fiber 2 is used as woof and the woof is intermittently woven, The woven textile is slitted at positions (a-a) in the drawing to extract an optical fiber structure arraying the optical fibers 1 like a reed screen and having the length La. The normal fiber 2 is woven only at both the end parts of the optical fibers 1. In this invention, the fiber array on one side is held easily, precisely and rapidly without any skilled technique independently of the number of optical fibers and their length and diameter, so that the productivity is sharply improved and the defective ratio of products can be sharply reduced.

Abstract:
PURPOSE:To prevent any tension from being applied to a flat yarn by allowing the flat yarn to extend inside a case in a state substantially having no annular part. CONSTITUTION:A flat yarn 10 is allowed to extend inside a case 20 in a state where its one end 12 can be drawn out outside the case 20 and has substantially no annular part. The extension of the flat yarn 10 in the case 20 is generally enabled by introducing the yarn into the case 20 from the side of other end part 14 thereof, while giving a swing thereto to the right and left and back and forth. Further, this extension of the flat yarn 10 in the case 20 is arranged as possible to allow the other end part 14 of the flat yarn to be drawn out outside the case 20, similarly with one end part 12.
Abstract:
PURPOSE:To obtain a plastic molded article useful as rotary parts or sliding parts, by forming an infiltrated layer of an aqueous dispersion of fluorine- contained resin in the interior of a plastic molded article on the surface side. CONSTITUTION:An aqueous dispersion of a fluorine-contained resin (preferably containing wax and/or silicone as well as the fluorine-contained resin) is brought into contact with the interior of a plastic molded article such as rotary parts, sliding parts, etc. on the surface side, so that an infiltrated layer having >=5mu (preferably >=20mu) is formed on the interior of the molded article on the surface side. The aqueous dispersion of the fluorine-contained resin attached to the surface of the molded article is removed by washing or wiping out, to give the aimed molded article. The contact treatment is preferably carried out under reduced pressure at
Abstract:
PURPOSE:To lengthen the life of a belt and to prevent a trouble by providing a flexible sheet in such a manner as to rotate round the vertical shaft on the lower portion and an extension portion of a conveyer at the end portion of the belt conveyer. CONSTITUTION:At the end portion of a belt conveyer 5, support boards 1, 2 are provided on the lower portion and an extension portion, respectively, and a flexible sheet 3 is disposed on each of the boards in such a manner as to rotate round a vertical shaft 4. In this case, the flexible sheet 3 is constructed in such a manner as to rotate smoothly by adopting a slide system, a fluid film system, a rotor contact system or the like. In this arrangement, when a work is received on the flexible sheet 3 and turned to a position of a conveyer belt to take over the work, the sheet 3 turns and enters below the conveyer belt, so that the work is transferred onto the conveyer belt. In this arrangement, the life of a belt can be lengthened, and the constitution is simple to decrease a trouble.
