Title: Wound-form substance of resilient yarn and winding method
Inventor: KAI KAZUHIRO
IPC: B65H54/28
Filed: 1993-05-07
Abstract: PURPOSE:To prevent the drop of a yarn from a peripheral surface during handling and unwinding and to prevent the occurrence of a trouble, such as end down, at a post process by a method wherein an outermost yarn layer having a specified winding width is formed on the upper layer of an ordinary yarn layer between the two selvages of the ordinary yarn layer. CONSTITUTION:A wound-form substance comprises an outermost yarn layer 2 wound in a winding width narrower than width between two selvages 3; and an ordinary yarn layer 4 wound in a winding width between the two selvage parts 3 therebeyond. The outermost yarn layer 2 is formed in a winding width being 70-90% of width between the two selvages of the ordinary yarn layer 4. In the so formed wound-form substance, manufacture is effected such that, before winding of the ordinary yarn layer 4 is completed, the winding width of the outermost yarn layer 2 is decreased in a way to separate a friction roll and a full bobbin away from each other. This method prevents the drop of a yarn during handling and causes maintenance of the tension of a yarn as it is since the yarn of the ordinary yarn layer 4 is tied by the outermost yarn layer 2 of an upper layer, and prevents the occurrence of a slack during unwinding of the ordinary yarn layer 4.

IPC: G06K7/12
Filed: 1987-04-30
Abstract: PURPOSE:To thin a hologram scanner by laminating at least two pieces of holograms, in a crossing state and forming a hologram window. CONSTITUTION:A read window is formed by a hologram window 3 provided with at least two pieces of first and second band-like holograms 31, 32 for crossing each other. Laser scanning beams 33, 34 emitted to the outside of a device pass through the hologram window 3, and also, deflected by the band- like holograms 31, 32, and become scanning beams for irradiating a medium to be read, and a signal scattered beam from the medium to be read passes through the band-like holograms 31, 32 of the hologram window 3 and detected by a photodetector of the inside of the device. Since the read window it self is synthesized in advance to a crossed scanning pattern, such a space as usual is not required, a distance extending from the read window to the window cover is shortened and a hologram scanner can be thinned.

IPC: G03G5/14
Filed: 1988-04-28
Abstract: PURPOSE:To improve the quality of an image by incorporating a copolymer of ethylenic hydrocarbon and acrylic ester and/or methacrylic ester as copolymerizable components and a photoconductive substance which does not practically exhibit sensitivity to light for imagewise exposure into an intermediate layer. CONSTITUTION:A copolymer of optionally substd. ethylenic hydrocarbon and acrylic ester and/or methacrylic ester as copolymerizable components is used as a binder in an intermediate layer 7 interposed between a photosensitive layer 8 and an electrically conductive support 1. The intermediate layer 7 contains a photoconductive substance which rectifies optical carriers generated in in the photosensitive layer 8 at the time of exposure without reducing resistance as bulk, increases sensitivity and can lower residual potential. Since the photoconductive substance does not practically exhibit sensitivity to light for imagewise exposure, the resistance of the intermediate layer 7 is kept moderate, the injection of holes from the support side is effectively prevented and the occurrence of black spots can further be prevented.
