Title: Plasma oxidation method
Inventor: MAEDA MUNEO
IPC: B01J19/08
Filed: 1979-11-06
Abstract: PURPOSE: To make plasma excitation state longer in life and make oxidation treatment speed high by using the mixed gases consisting of mixture of nitrogen gas and oxygen gas for the gas to be admitted into the reaction chamber in a plasma oxidation method.  
     CONSTITUTION: Oxygen gas admitted and heated in a reaction chamber 3 is excited to plasma by the high frequency electric power from a waveguide 4, whereby the material 2 to be oxidized is oxidized. If at this time the mixed gases consisting in mixing nitrogen gas in oxygen gas are used, the 2nd light emitting part L 2  is produced in succession to the 1st light emitting part L 1  and the plasma excitation state continues long in time; therefore, the rate of oxidation reaction for the material 2 improves and nevertheless the degree of freedom in the apparatus manufacture increases.

Title: Pressure sensor
Inventor: IZUTSU MASAYUKI
IPC: G01L21/10
Filed: 1986-06-19
Abstract: PURPOSE:To obtain a small-sized, stable sensor by forming a heat radiation layer on the 1st optical waveguide formed on a substrate and a heat insulation layer on the 2nd optical waveguide, and supplying light beams which have a specific phase relation to both optical waveguides. CONSTITUTION:A Mach-Zehnder interferometer 11 consists of an optical waveguide 3 for input, optical waveguides 1 and 2 which branch from it, and an optical waveguide 4 for output where their outputs are multiplexed. The heat radiation layer 12 is provided covering one optical waveguide 1 and the thick heat insulation layer 13 is arranged on the remaining part of the surface of a substrate 10 including the other optical waveguide 2. Then when heat is supplied from below the substrate 10 by a constant quantity, the temperature of the optical waveguide 1 where the heat radiation layer 2 is arranged varies with pressure, so a temperature difference is generated between the optical waveguides 1 and 2. A phase difference is generated between light waves propagated in the optical waveguides 1 and 2 owing to the temperature difference and the intensity of light obtained from the output optical waveguide 4 varies with the phase difference. For the purpose, the output light is detected to detect the pressure by the optical integrated circuit.

Filed: 1988-06-11
Abstract: PURPOSE:To abolish efforts to fixedly adhere electronic parts to a board individually with resin by a method wherein lead wires of other electronic parts are inserted into a through hole of a circuit board on which electronic parts are soldered, and are soldered with a solder-resistance mask plate against it. CONSTITUTION:A solder-resistance mask plate 6 is one in which a thin body 8 having solder resistance is fixed to a picture-frame-like supporter 7. In electronic parts soldered to a circuit board beforehand, a portion desired to avoid the contact with solder which is melted again is a non-opening 9, and a portion desired to be in contact with a molten solder, for example, a portion equivalent to a lead wire terminal lead-out portion, is made an opening 10 by removing the thin body. Such solder-resistance mask plate 6 is contacted with the main surface of a wiring board 1 in which electronic parts are mounted. Lead wires of electronic parts with lead wires are inserted into the through hole of the board from the rear surface and directed to the main surface, and the main surface is contacted with the molten solder layer, and lead wires are connected to a conductor on the board. This abolishes the need for fixedly adhering electronic parts individually on a board by using resin for contact.

Title: Matrix for fuel cell

IPC: H01M8/02
Filed: 1983-08-08
Abstract: PURPOSE:To increase the mechanical strength and the electrolyte-holding ability of a matrix for a fuel cell by constituting the matrix of the first layer consisting of SiC fibers fixed together with a fluorine resin binding agent in the direction parallel to the electrode surface and the second layer formed by packing SiC fibers with beta-type crystalline SiC fine powder and a fluorine resin binding agent. CONSTITUTION:After SiC fibers 12 are added to an aqueous solution of a surface active agent, ethylene glycol is added before the mixture is stirred. The thus prepared mixture is then combined with an aqueous mixture solution containing PTFE11. Next, two pieces of sheet-like thin SiC fiber films are formed by the thus obtained mixture using a metallic net. The thus formed thin SiC fiber film consists of a network in which SiC fibers 12 are tangled with each other in the surface direction. Next, one of the two thin SiC fiber films is impregnated with a mixture solution prepared by adding both ethylene glycol and a PTFE mixture solution containing a surface active agent to beta-type SiC paticles 10 before performing drying. After that, these two thin sheet-like films are placed upon each other before the laminate body is heated and pressed so as to unify them owing to the binding agent PTFE interposed, thereby obtaining a matrix having a double-layered structure.

Title: Hydraulic device in battery type industrial vehicle
Inventor: SUGIYAMA SHOJI
IPC: F15B21/14
Filed: 1990-06-01
Abstract: PURPOSE:To prevent occurrence of noise and vibration by changing over a feedback change-over valve at the pilot pressure corresponding to a hydraulic value at the time of expansion and contraction of a lift cylinder and absorbing irregular fluctuation of the pilot pressure between a lift control valve and the lift cylinder. CONSTITUTION:When a lift lever 6 is changed over from its neutral position to its lower position with a fork in an unloaded or slightly loaded condition, a change-over valve 11 is changed over to (b) position in advance if return hydraulic pressure cannot function an electric motor 42 as a generator. A pressure is not given to the junction Z of a by-path piping line D, so that an opening check valve 27 is not opened. Therefore, pilot fluid P in an operating pilot piping line 26 opens a closing check valve 21 to flow out pilot fluid gathering in a pressurizing pilot piping line 19 into a drain piping line 12. Because the change-over valve 11 which has already been changed over to (b) position does not change its condition, it is thus possible to prevent vibration and so forth which occur due to changing-over action.
