Title: Manufacture of catalytic sheet of electrode for fuel cell
Inventor: KAMITOMAI SHINJI
IPC: H01M4/88
Filed: 1991-05-21
Abstract: PURPOSE:To provide a porous structure having extremely high porosity, by impregnating a flocculent object with epsilon-caprolactam in melting state to knead it to be dispersed uniformly in kneaded materials, and by making the lactam exist in a sheet as solid or solid state with high viscosity following vaporization of solvent also during a rolling process. CONSTITUTION:Catalytic fine grain suspension and dispersion of fluororesin are mixed each other, and catalytic fine grain and fluororesin are flocculated together in the mixture, and flocculent object is impregnated with epsilon-caprolactam in melting state and epsilon-caprolactam is removed by provisionally-burning after a rolling process. In this case, weight percentage of epsilon-caprolactam in epsilon- caprolactam solution is 40-87%. As epsilon-caprolactam makes solution having moderate flowability with a little amount of solvent, is caked or has high viscosity by vaporization of a little amount of solvent, and is removed easily with provisional-burning temperature of 150 deg.C-200 deg.C, methyl alcohol, solvent naphtha and others out of water and organic solvents are enough to be used as solvent.

Abstract: PURPOSE:To prevent an unrequired radiant wave generated from a feeder circuit from being affected adversely on the radiation pattern of an antenna, by performing feeding to a print dipole antenna and a slot line formed on the front side of a dielectric substrate with a microstrip line formed on the rear side. CONSTITUTION:An electromagnetic wave transmitted on the microstrip line 15 in which a metallic foil 12 is set as a ground conductor excites the slot line 14 at a coupling part 16. At this time, since the microstrip line 15 is positioned within a spatial part 19 covered with the metallic foil 12, no unrequired radiant wave is leaked to the outside including the radiating direction D of the antenna. And the electromagnetic wave excited on the slot line 14 arrives at the print dipole antenna 13 through the spatial part 19 and a cavity 18, then, excites the antenna. The metallic foil 12 in the periphery of the antenna 13 is removed, and only the dielectric substrate 11 remains, and since the bottom part of the cavity 18 equivalent to a reflecting plate is positioned at a position separated by around 1/4lambda, the electromagnetic wave can be radiated effectively in the radiating direction D.

Title: Abnormality detecting method for write head of magnetic storage reproducing device and system therefor
Inventor: GOTO MASANORI
IPC: G11B20/18
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To reduce the erroneous judgment of an abnormality detection in a write head by outputting prescribed write data to a R/W channel while executing a write operation and outputting the write data from a controller without performing the code modulation of the write data while outputting a control command to a recording circuit being in the R/W channel. SOLUTION: At the time of a write command, a controller 105 makes a R/W channel 104 and a R/W amplifier 103 output a write operation command 113 by outputting a write operation command 117 to a MPU 106. The R/W channel 104 performs the code modulation of write data 111 by a recording circuit 141 to transmit the modulated write data 115 to the R/W amplifier 103, which converts the write data 115 into current waveforms by a write driver 131 to transmit the current waveforms to a write head 102, which records them on a recording medium 101. A WUS detecting circuit 132 monitors the operating state of the driver 131 and when there is an abnormality, the circuit outputs a WUS signal 114 to the MPU 106, which performs an erroneous detection processing.

Title: Manufacture of hydride secondary battery
Inventor: FUKUNAGA HIROSHI
IPC: H01M10/28
Filed: 1991-04-19
Abstract: PURPOSE:To reduce self discharging by charging an accumulator in the opening system after it is assembled, by keeping the accumulator at 30-60C, by removing nitric ion, and by stirring the accumulator or bubbling it with inert gas after it is kept. CONSTITUTION:By charging and keeping an accumulator in the opening system, NO3<-> (nitric ion) is reduced into NH3<-> (ammonia), and is dissipated to outside of the accumulator. As a result, self discharging due to NO3<-> is suppressed. As the temperature at which the keeping is carried out after discharging is higher, reduction reaction is further promoted, however, when the temperature exceeds 60 C, a polypropylene nonwoven fabric or polyamide nonwoven fabric that are used as separator are easily affected by heat. When the temperature becomes lower than 30C, the effect of promoting the reduction reaction is reduced. The period of keeping is different correspondent to the temperature at the time of keeping, however, a period of around 2-4 days is preferred. After the keeping, by stirring the accumulator or by bubbling it with inert gas such as argon, dissipation of ammonia to the outside of the accumulator is effectively carried out.
