IPC: H01M8/02
Filed: 1986-04-03
Abstract: PURPOSE:To obtain a reactant gas separating function necessary for a seperator, though using a porous carbon with low cost, by impregnating the porous carbon as a base with an electrolyte to form the separator. CONSTITUTION:A carbon powder film made of acetylene backed or a porous carbon base made by forming carbon powder under pressure is impregnated with phosphoric acid as an electrolyte to form a flat-plate-like separator 6, which is interposed between cell modules 1. A sealing tape 8 such as a Teflon tape is stuck to The peripheral surface of the separator 6 to hermetically seal the surface to it from an ambient gas. As a resule functions of a reactant gas separation and electric connection between cell modules, which are required for the separator 6, are fulfilled. Besides, the separator is less expensive than a separator made of a gas-impermeable carbon and is therefore more enconomic than it.

Title: Support material with low pit level
Inventor: RAABE GUENTER
IPC: B29C48/08
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To make the surface properties uniform and lower the pit level by imparting a form to the surface by a cooling roll with a structure manufactured electrolytically on the surface. SOLUTION: The roll to be used when manufacturing a support material is a roll which is chromium-plated and surface-treated by sandblasting. A surface structure can be created using a controlled process by reversing the direction of electric current using the control process during electroplating. These surface structures are projections with roundness distributed uniformly, and the roll is for cooling with a uniform roughness distribution Rz. The standard deviation of these cooling rolls is 0.050-0.120 μm, preferably 0.060-0.100 μm. Thus a surface with a uniform gloss value is produced on an extrusion-processed article.

Title: Preventing circuit for pop sound
IPC: G11B20/02
Filed: 1992-03-31
Abstract: PURPOSE:To effectively prevent pop sound generated at the time of recording and reproducing in a cassette tape recorder or the like by using constitution of a circuit of a small size and reduced electric power consumption. CONSTITUTION:When an external switch 13 is turned on, a power amplifier 18 is applied with DC voltage of 3 volts from a terminal 14 and amplifies an audio signal from an audio signal input terminal 24 to output it from an output terminal 25. In this constitution, when the external switch 13 is turned off, electric charge on a capacitor C1 is discharged via a load circuit 15, and a potential VA of an input side (point A) of a ripple filter 17 is rapidly reduced. And when it coincides with a potential VB (held approximately at 2.65V) of a decoupling terminal 20 side (point B) connected to a capacitor C2, a miller circuit 27 operates and a current is outputted. Due to this, a transistor Q3 is turned on, a current from a constant current source 19 flows in the transistor Q3 while bypassing, and current supply to the power amplifier 18 is interrupted. Therefore, operation of the power amplifier 18 is stopped before stopping input of an audio signal, and the generation of pop sound is effectively prevented at the time of switching off.

Abstract: PURPOSE: To prevent short-circuit and disconnection between multilayer interconnections by forming a interconnection layers without pointed angular section through the etching of two polycrystal layers of varied etching rate in an interconnection pattern after formed on a substrate.  
     CONSTITUTION: A polycrystal silicone layer 3 void of doped impurity is applied at a thickness of about 2000Å to a semiconductor substrate 1 on which an insulating  film 2 with a thickness of several hundred Å is formed and then, a polycrystal silicone layer containing impurity (P or the like) is applied thereon at the same thickness as the lower layer. After a photoresist film 5 is formed at the specified position, an etching is conducted. Consequently, a moderately slant surface is formed  thereon due to the difference in the etching rate between the upper and lower  layers. Then, after the removal of the resist film 5, annealing is conducted if necessary. In this matter, the impurity on the upper layer is allowed to diffuse into the  lower layer so as to make an even interconnection layer 6. The second interconnection layer is formed through an insulating film 7.

Title: Inter-station phase synchronization system
Inventor: NISHIKAWA NOBUHIRO
IPC: H04W92/00
Filed: 1994-04-18
Abstract: PURPOSE:To prevent phase synchronization error due to a reception of a transmission timing signal from a different base station by using transmission timing signals of plural patterns so as to identify a sender base station based on the pattern. CONSTITUTION:A base station 2 inputs a frame signal not including a transmission timing signal sent from a central station 1 via a relay line to a timing signal adder 13 via a line terminator 9. The adder 13 adds a transmission timing signal to each group of the received frame signal and sends the result to a phase synchronization device 10. The device 10 compares the phase of the transmission timing signal in the frame signal with a phase of a transmission timing signal in a frame signal from a phase reference station detected by the reception antenna 5 and the transmission timing signal detector 14. Furthermore, the transmission timing of the frame signal from the relay line is adjusted by the device 10 to eliminate the difference from the timing in both the timing signal. In this processing, the frame signal whose transmission timing is arranged with the phase reference station is sent to a mobile station 4 from the transmitter 11 via the antenna 3.
