Patent JP-S6319912-A (JP)
Title: Semiconductor relay circuit
Inventor: MORI YASUSHI
IPC: H03K17/78
Filed: 1986-07-14
Abstract: PURPOSE:To prevent generation of the heat of an output MOSFET by setting a switching element in series to an optical electromotive force diode array and making the switching element conduct at a time point when the output of said diode array rises up enough. CONSTITUTION:The optical signal received from a light emitting diode 1 reaches the gate of a switching element containing an optical trigger FET 3 to set the S (source)-D (drain) impedance of the gate at a low level. The voltage is produced at both terminals of a resistor 4 by the conduction of the FET 3 and the current produced by an optical electromotive force diode array 2. Thus the S-D impedance is set at a low level for an output MOSFET 5 of an n channel type E (enhancement) mode. Then the MOSFET 5 is kept in an ON state and a conduction state is kept between relay output terminals 7 and 7'.

Title: Production of glass thin film
Inventor: ITO MASUMI
IPC: C03B8/02
Filed: 1990-06-25
Abstract: PURPOSE:To enable production of a thick film having no defect by combining the production of functional glass by sol-gel method and the production of thin films by sputtering. CONSTITUTION:A mixture soln. is prepared by adding water and alcohol to metal alkoxide expressed by the general formula M(OR)4 (wherein M is metal and R is alkyl group) and further adding a functional inorg. material. This mixture soln. is hydrolyzed and polymerized by dehydration condensation to synthesize a bulk glass. Then, by using this bulk glass as a target for sputtering, a glass thin film having the same compsn. as that of the bulk glass is formed on a substrate. By this method, the bulk glass can be obtained without subjecting to high temp. process so that no influence is given to the various kinds of dopants to be added. By forming thin films by sputtering, the compsn. of thin films does not change and thereby, film thickness can precisely be controlled. Defects such as cracks or peeling are hardly caused even when the film is made thick.

Title: Separating and carrying method of transfer material in electrostatic recording device
Inventor: IYAMA SADAOMI
IPC: G03G15/00
Filed: 1982-09-25
Abstract: PURPOSE:To prevent disorder of a toner image, disorder of a transfer image and a shift of the transfer image, by installing a flexible belt-like separating member on one end side of an intermediate picture supporting body, so that when a part of said member contacts with the surface of the picture supporting body, and both its side parts are separated from the surface of the picture supporting body and also contact with a transfer material, said member can be bent in accordance with its force, and feeding the transfer material so that its tip hits against the entrance side part of the part where the separating member does not contact with the picture supporting body. CONSTITUTION:A transfer material 4 is extruded by a paper feed roll and collides with a separating belt provided on an inlet of a space R, but since the belt is flexible and also is detained by a spring so as to be bent freely, the belt is pushed by the transfer material and forms a bend A, by which a shock due to a collision of the transfer material is absorbed, and it moves in the direction in which a contact time of the transfer material and a drum face 1a is lengthened. Some electrostatic attraction is left between the drum and the transfer material even after destaticization, therefore, the transfer material pushes up the separating belt, a bend part B is formed, and when the transfer material advances further and the rear end of the transfer material passes through the part A, the bend of the part A disappears, the bend of the part B increases, and it moves in the direction in which a contact time of the transfer material and the drum is extended, therefore, disorder of a transfer image and transfer shortage are prevented.
