Title: Coating device of photo sensitive drum for zerography
Inventor: YAGISHITA AKIO
IPC: G03G5/00
Filed: 1977-12-23
Abstract: PURPOSE: To form a highly smooth coating on a photosensitive drum by making the supply and recovery of a photosensitive solution possible and by using vertically movable coating blade so as to effect the coating operation in the atmosphere of solvent vapors.  
     CONSTITUTION: A coating blade 4 is positioned in the vicinity of a drum 1, while turning the drum 1, and a photosensitive solution is supplied to the blade 4 through a hose 6 from a tank 5 vented to the atmosphere so that a coating 9 is formed on the surface of the drum 1. When this coating 9 is formed all over the circumference of the drum 1, the blade 4 is retracted upward, and the tank 5 is connected with a vacuum source so that the excess photosensitive solution is sucked and recovered into the blade 4. On the other hand, the solvent stored in a solvent reservoir 8 is evaporated from the holes in the bottom of a mirror surface forming plate 7 so that it steals into the clearance between the drum 1 and the plate 7 thereby to shield the drum 1 with the solvent vapors. Thus, the solvent is prevented from being abruptly evaporated from the coating 9 thereby to smoothen the coating.

Title: Optical switch
Inventor: MINEMURA HIROYUKI
IPC: G02F1/31
Filed: 1987-06-24
Abstract: PURPOSE:To enable an optical switch to operate even if a conductive path is not used by using a superconductor which makes a state change between superconduction and normal conduction. CONSTITUTION:This optical switch is constituted by utilizing the change in the interaction with light arising from the state change between the superconduction and the normal conduction of the superconductor 10 formed on a transparent substrate 20. Light is reflected by a Meissner effect when the light is projected on the material in the superconducting state. The Meissner effect disappears and the quantity of reflected light decreases when the material is transited to the normal conducting state by temp., electric current and magnetic field, etc. The change in the reflectivity or transmissivity of the superconducting state and the normal conducting state is settable as desired by adequately selecting the film thickness of the superconducting material at this time. The optical switch of the simple constitution is thereby obtd.
