Title: Production of polymeric electrolyte membrane for fuel cell and fuel cell
Inventor: MURATA MAKOTO
IPC: H01M8/10
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To uniformize a membrane thickness by forming a polymeric electrolyte on the inner peripheral surface of a cylinder by injecting a liquid medium containing a specific amt. of the polymeric electrolyte and a solvent having a specific azeotropic point in the cylinder having a cylindrical inner peripheral surface and volatilizing the solvent by the rotary centrifugal force of the cylinder. SOLUTION: At first, a predetermined liquid medium is injected into a cylinder having a cylindrical inner peripheral surface. This liquid medium contains 1 wt.% or more of a polymeric electrolyte and a medium having a b.p. or azeotropic point of 60-220 deg.C. Subsequently, the cylinder holding the liquid medium is rotated and the liquid medium is applied to the inner peripheral surface of the cylinder by the centrifugal force generated by the rotation of the cylinder and the solvent thereof is volatilized. By this constitution, the polymeric electrolyte having an almost uniform thickness and a cylindrical shape is formed on the inner peripheral surface of the cylinder. By this method, the thickness of a polymeric electrolyte membrane 12 for a fuel cell is uniformized and the capacity of the fuel cell can be stabilized.

Abstract: PURPOSE:To accurately and easily form the necessary thickness of a thin film in case of etching by simultaneously etching predetermined parts except a thin film structure of a semiconductor substrate, emitting a light to the predetermined part during etching to detect the depth of etching, thereby controlling the etching. CONSTITUTION:Silicon oxide films 2, 3 are formed on upper and lower surfaces of an N-type Si semiconductor substrate 1, and a P-type diffused resistance region 4, an aluminum wiring layer 5 and a PSG film 6 are formed. Then, a diaphragm 7 and the film 3 of an etching end point detecting region 9 are removed by photoetching, with the film as a mask it is etched. A light is emitted perpendicularly from a light source 10 through an optical system 11 to the region 9 during the etching, and the reflected light is detected by a photodetector 12. An etchant uses a crystal surface selective etchant. Accordingly, the reflected light is generated with respect to an incident direction while the surface perpendicular to the incident direction of the light as designated by a broken line 9' remains on the way of etching, but when a V-shaped groove is completed, the reflection of the incident direction becomes almost naught.

When the power is supplied to an automatic betting ticket vending device, the display position flag is set at 0 and the part 1 monitors whether a race updating signal is received from the host or not. If so, the flag is inverted to 1 from 0. Then, the part 3 changes the display position of the idle screen based on the flag of the part 4. That is, a fact whether the flag is set at 0 or not is checked. If so, the idle screen is shown at a prescribed screen position of 0. Meanwhile, the idle screen is shown at a prescribed screen position of 1 if the flag is set at 1 respectively.

Title: Submerged arc welding method
Inventor: MIYAZAKI MAKOTO
IPC: B23K9/18
Filed: 1977-10-21
Abstract: PURPOSE: To enhance the welding efficiency of submerged arc welding by a method in which a filler metal bar is placed in beveling portion covered with flux and then the core wire and the filler metal bar are melted for welding.  
     CONSTITUTION: The snap metal 4 is placed on the back of the beveling of the base metal 3, and then the TIG welding core wire 9 consisting of single or plural filler metal bars are inserted into the beveling portion and covered with the flux 2. Then, core wire 1 is thrust into the flux 2 to make a submerged welding. Because arc during welding occurs under the condition of being covered with the flux 2, the concentration of heat can be attained, and therefore the TIG core wire 9 is completely melted. The molten core wire 1 and the TIG core wire soldify as the welding proceeds to constitute the deposited metal 7. In this method, if the kind of filler metal is changed, a variously combined welding can be made
