Filed: 1983-05-12
Abstract: PURPOSE:To provide a combustion device which is of a small size and light in weight and can perform safe combustion for a long time, by a method wherein contact oxidation reaction is made in gas fuel, produced by evaporating methanole, ethanole, ether, aceton, methane, buthane, etc., by means of a ceramic porous material by which a platinum group metal is carried. CONSTITUTION:The lower part of a fuel feed porous material 3 is conditioned to be immersed in fuel 2 stored in a fuel tank 1, and thereby the liquefied fuel 2 is sucked up by a capillary phenomenon, and almost of the fuel produces a gasified fuel during the suction process, and if a shutter 4 is opened, the fuel flows upward and is fed to a ceramic porous material 5 by which a catalyst component located above the shutter 4 is carried. Thereby, the gasified fuel performs oxidation reaction, i.e., combustion by the action of platinum, being a catalyst component, within a ceramic porous material 5. Utilization of excellent oxidation catalyst action of a platinum group metal enables efficient combustion for a long time without needing an ignition source.

Title: Manufacturing method for photoconductive coat of image pickup tube
Inventor: MARUYAMA AKIO
IPC: H01L31/04
Filed: 1982-05-21
Abstract: PURPOSE:To obtain a photoconductive coat for an image pickup tube with high quality, high yield, and low cost by dividing the formation process of the photoconductive coat into a number of processed and providing a process that removes a material of a characteristic defect made to adhere to the surface of the photoconcuctive coat between them. CONSTITUTION:A blocking coat formation substrate in which the first blocking coat is formed on the surface of the transparent photoconductive coat of a transparent glass substrate is set in a high frequency sputtering device and reactive sputtering is performed while the argon gas pressure and the hydrogen gas pressure are being adjusted. When the thickness of the photoconductive coat (amorphous hydrogenated slicone film) reaches 1,000 to 10,000Angstrom , the substarate is taken out from the high frequency sputtering device and ultrasonic cleaning is performed for it. Then the substrate is checked and defective substrates are removed and then the same processing as the said first reactive sputtering is performed by transferring only good substrates to the subsequent second reactive sputtering process. Furthermore, the second cleaning and the second check are performed in the same way as the said first cleaning and the said first check, respectively. As a result, the photoconductive coat of 1 to 4mum in thickness can be obtained by the processes up to the fourth reactive sputtering process.

Title: Strip accumulator
Inventor: WATARAI MASARU
IPC: H02P29/00
Filed: 1986-04-15
Abstract: PURPOSE:To prevent the buckling and meandering of a strip by providing an oscillation signal generating device which makes the controlling current of a torque control means a pulsating current and always driving a motor by means of this oscillating signal. CONSTITUTION:The torque of a motor 27 is controlled by a torque control device 29 and a carriage roller 21 is moved so as to make this torque a defined value, to restrain change in the tensile force of a strip 31 which is put around the carriage roller 21. In this case, a torque controlling current is made a pulsating current by an oscillation signal generating device 30. Thereby, the value of the control signal of torque is always changed, causing the motor 27 to slightly rotate at all times. Accordingly, since a frictional force which acts on a moving mechanism for moving the carriage roller 21 does not become a statical friction, variation in tensile force which acts on the strip 31 can be restrained. Accordingly, the bucking and meandering of a strip 31 can be prevented.
