Title: Electrolyte film for solid polymer fuel cell and solid polymer fuel cell using same
Inventor: ISONO TAKAHIRO
IPC: H01M8/02
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To provide an electrolyte film capable of enhancing strength without degrading power generation efficiency and a solid polymer fuel cell using the electrolyte film.

The electrolyte film 10 is formed so that a thickness of the electrode forming region 12 becomes thinner than that of the outer peripheral region 14. A cell unit 26 is structured so that a cell 24 includes the anode 20 formed on one side of the electrode forming region 12 of the electrolyte film 10 and the cathode 22 formed on the other side of the electrode forming region 12, and a fuel chamber 30 is formed on an anode side of the cell 24 and an oxidizing agent chamber 34 is formed on a cathode side of the cell 24.

Title: Optical spectrum analyzer
Inventor: OSHIMA SHIGERU
IPC: G02F1/335
Filed: 1988-02-29
Abstract: PURPOSE:To obtain a large dynamic range by projecting collimated light in plural directions and making the light incident on an acoustooptic modulator. CONSTITUTION:A semiconductor laser 1 has light emission parts 1a and 1b and a lens 2 collimates the light from the laser 1 and projects two beams on the acoustooptic modulator. Here, when a high-frequency signal is applied to the electrode of the modulator 3, an acoustic wave 4 is generated and a high- sensitivity optical spectrum analyzer is formed which has high diffraction efficiency to a light beam satisfying the Bragg condition with said acoustic wave 4 on condition that the light beam is the light beam from the light emission part 1a. The light from the light emission part 1b, on the other hand, does not satisfy the Bragg condition, so an optical spectrum analyzer having low sensitivity is formed. Those light beams are incident on different photodetectors in a photodetector array 6 through a condenser lens 5. Thus, a large dynamic range like a dynamic range formed by connecting the dynamic ranges of the optical spectrum analyzers is obtained.

IPC: G06K1/12
Filed: 1987-02-27
Abstract: PURPOSE:To print a bar code with high quality, by constructing a bar code printer such that a linear heating element having same length as the height of bars in the bar code is formed, then it is heated through a heating element driving circuit to print the bars with the heat onto a thermographic paper, the thermographic paper is fed through a paper feed mechanism. CONSTITUTION:A bar code signal encoded through a host CPU3 is driven in by means of a driver 2 which can drive a heating element 1 sufficiently. The drive signal is employed for driving the heating element 1. Turning ON, OFF of the heating element 1 is determined based on the level of the driven bar code signal. A platen 5 being controlled through a host CPU3 is driven by a platen driver 4, and a bar code is printed by feeding a thermographic paper in the direction perpendicular to the bar code. Resolution of the bar code can be regulated by controlling drive signals for the heating element 1 and the platen 5. Since a linear heating element 1 is employed, the edge portion of the bar can be printed linearly with high quality.

IPC: G11B7/24035
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To provide an optical information recording medium capable of having an enough modulation degree under an enough small state of thermal nonuniformity and writing to be suitable for high speed recording and high speed reading by suppressing deterioration of jitters caused by the thermal nonuniformity generated at the time of high speed recording and unbalanced pit lengths and also making a light absorbing layer enough thin in thickness. SOLUTION: This optical information recording medium is for recording information by irradiating the light absorbing layer 3 with recording light L1, and an average film thickness Dav of the light absorbing layer 3 is 40 nm<=Dav<=100nm, and then when an EFM signal is recorded under optimum power, a dyestuff survival rate E in the light absorbing layer 3 is 0.6<=E<=0.9. Thus, since the average film thickness and the dyestuff survival rate of the light absorbing layer are regulated to fall within the specified ranges, the optical information recording medium having a satisfactorily good characteristic against jitters and an enough modulation degree even in the case of high speed recording is obtained.

Title: Preparation of bisdialkylaluminum oxane
Inventor: SATOU HIROSHI
IPC: C07F5/06
Filed: 1981-03-26
Abstract: PURPOSE: To obtain the titled compound by an easy operation with high precision of reaction, by adding water which is saturated in a hydrocarbon solvent or contained in it in a concentration lower than it to a trialkylaluminum, followed by reaction.  
     CONSTITUTION: Water which is saturated in a hydrocarbon solvent (e.g., pentane, etc.) or contained in it in a concentration lower than it is added to a trialkylaluminum shwon by the formula II (R is 1W6C alkyl), followed by reaction, to give a compound shwon by the formulaI. The reaction is carried out in an atmosphere of dried nitrogen or argon. The temperature should be a temperature < the decomposition temperature of an individual aluminium oxane.  
     EFFECT: Reaction uniformity is prevented because of no partial existence of water, and the saturation solubility of water in the solvent is constant depending upon temperature, so that a necessary amount of water can be introduced in good repreducibility only by temperature control. Vigorous reaction can be suppressed free from side reactions.
