Title: Manufacture of electrode for fuel cell
Inventor: MAOKA TADANORI
IPC: H01M4/88
Filed: 1982-06-15
Abstract: PURPOSE:To obtain a high-performance electrode for a fuel cell by mixing a dispersion liquid of catalyst particles and a dispersion liquid of a water-repellent binding agent together with a surfactant, and applying the thus prepared dispersion liquid to a porous base body so as to cause the catalyst particles to be homogeneously dispersed in the surface of the base body. CONSTITUTION:A catalyst particle dispersion prepared by dispersing catalyst particles of platinum or the like carried on carbon powder or the like in water, and an aqueous dispersion of a binding agent such as polytetrafluoroethylene are mixed together with a nonionic or an anionic surfactant. The thus obtained catalyst mixture, while maintaining its dispersion form, is applied to a porous base body made of carbon paper or the like, then dried, thereafter being homogeneously pressed with a roller or the like. Following that, the pressed body is heated in an inactive atmosphere so as to obtain an aimed electrode for a fuel cell. By the means mentioned above, the catalyst particles and the binding agent are prevented from being aggregated, and the catalyst particles disperse and permeate in the base body. Consequently, the life of the performance of the electrode is lengthened.

Title: Frequency detecting circuit
Inventor: NISHIKAWA AKINARI
IPC: G11B20/10
Filed: 1982-06-15
Abstract: PURPOSE:To reduce the clock margin of a counter, by applying a demodulated clock signal and its inverted signal to each of counters set in parallel to each other and thn comparing these outputs with each other by a comparator. CONSTITUTION:A counter type register 126 supplies the register value 128 equivalent to the maximum inverting period Tmax to a comparator 124. The comparator 124 compares addition data 122 with the value 128 and then transmits an output pulse 130 to the register 126 only when the data 122 is larger than the value 128. Then the register value is increased by one. These operations are repeated within a prescribed period, and then the register 126 delivers the register value 132 in the form of the final maximum inverting period which is counted with a frequency double as high as a demodulated clock signal 114. Therefore, the resolution converting the detection of frequency can be substantially improved double, and the time margin required to counters 106 and 108 is equal to the conventional value. This process results in a reduction of the clock margin of a counter.

At the time of pushing the pressurized punch 3, when the sintered body 4 passes through the tapered part, i.e., the small diameter part 1c in the die 1, this is compressed to the shaft axial direction and the cross section is re duced and compacted. The sintered body 4 is lengthened in the axial direction and the mandrel 2 is shifted to the pressurizing direction. When the whole part of the sintered body 4 passes through the small diameter part 1c in the die, the mandrel is pulled out. By this method, the cylindrical metal parts having 0.5-2mm thickness can be obtd.

Title: Inverter
Inventor: KIMURA ARATA
IPC: H02M7/515
Filed: 1981-07-03
Abstract: PURPOSE:To reduce a loss of an inverter by storing the charged charge of a snubber capacitor in a GTO, a snubber capacitor and an auxiliary capacitor forming a closed loop, thereby eliminating a snubber resistor. CONSTITUTION:When a GTO1 is turned ON, the charge of a snubber condenser C1 is charged through a GTO1, a current limiting reactor L1 and a diode D13 in an auxiliary capacitor C5. When the GTO1 is then turned OFF, a current continuously flows in a closed loop of a GTO4, a flywheel diode D1 and a current limiting reactor L2 by the energy of a load. Accordingly, the terminal voltage of the GTO2 becomes substantially zero, and the charged of the capacitor C5 is thus discharged through the closed loop. In this manner, a snubber resistor can be eliminated, thereby reducing the loss of an inverter.
