Title: Power generation system of fuel cell
Inventor: TAKEMOTO TOSHIAKI
IPC: H01M8/04
Filed: 1988-02-05
Abstract: PURPOSE:To prevent lack of hydrogen, remove adsorbed oxygen and prevent performance being worsened while power generation is stopped by supplying inert gas and hydrogen gas to an oxidant electrode and a fuel electrode respectively and turning a resistor on/off in accordance with a detected value of hydrogen concentration at an outlet of the oxidant. CONSTITUTION:In a process in which power generation of a fuel cell is stopped, supplying oxidant to an oxidant electrode 1b is stopped, to which inert gas is supplied from an inert gas supplying system 4 to purge oxygen remained thereof. On the other hand, with starting stop operation, a resistor 7 provided at a direct current output is turned on to energize the fuel cell. This causes that adsorbed oxygen is consumed and removed due to reaction of the oxygen adsorbed to the oxidant electrode 1b and hydrogen supplied to a fuel electrode 1a. In this case, when a voltage detected by a voltage detector 6 is high, a control device 8 selects a tap so as to minimize a value of the resistor 7. With procceding removal of the adsorbed oxygen, the oxygen is removed which reacts with the hydrogen and a current flows between the electrodes in accordance with electromotive force of a concentration cell due to concentration difference of the hydrogen. Then, the resistor 7 is turned off.

Title: Multi-point data transmission/reception system
Inventor: FUJIMURA NORIAKI
IPC: H04B7/005
Filed: 1979-03-02
Abstract: PURPOSE:To avoid the undesired continuation of the divergence state by transmitting the disturbance signal to give divergence to the automatic equalizer of the MODEM in the center unit and at the same time inhibiting transmission of the synchronization signal to answer the resynchronization signal sent from the side of the center unit. CONSTITUTION:Center unit 1, terminal unit 5A and others form the multi-point data transmission/reception system as well as MODEM2 and 4A incorporating automatic equalizers 9 and 16. MODEM4A of unit 5A detects the divergence state of equalizer 9 of its own at divergence state detection part 17, and then the disturbance signal is transmitted through disturbance signal transmission part 14 to give divergence to equalizer 9 of MODEM2 in unit 1 based on the output of part 17. And at the same time, the transmission is inhibited 7 for the synchronization signal to answer the resynchronization signal sent from unit 1. As a result, the undesired continuation can be avoided for the divergence state.

Abstract: PURPOSE:To obtain excellent connecting strength of a semiconductor device and to eliminate the adverse thermal influence to other parts by having heating means for a semiconductor element placing block and a capillary for supplying a fine wire respectively. CONSTITUTION:A semiconductor element 13 secured by a low melting point solder 14 onto a lead frame 15 is placed on a block 16 at the lead frame 15, and the electrodes are connected by a gold ball 12 at the end of a capillary 11.

Thus, since temperature necessary to thermally pressing is applied from above and below by two heat supply units, the gold wire can be connected with the heat of the minimum value as required, and the heat transferred to the low melting point solder 14 is reduced as compared with the conventional one. Accordingly, the melting of the solder and displacement of the position can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To keep each power load operating and prevent malfunctions of the loads due to the influence by external noise by turning a power reducing signal on and off repeatedly according to set stop time and operation time to reduce power to be supplied to a corresponding load. SOLUTION: When a demand operating section 1 outputs a cut-off signal to a power load 24, a control signal outputting section 2 (a power reducing signal controller) controls the output of the cut-off signal according to a preliminarily set time. To be more specific, when the demand operating section 1 outputs a cut-off signal to a certain power load, the control signal outputting section 2 outputs the cut-off signal and stops the output of the signal to the load, each for a specified period of time set for each operation. This operation is repeated until the demand operating section 1 stops outputting the cut-off signal. By this method, each power load can be kept operating and the interference of noise, etc., can be prevented.
