Title: Hydrogen geneator
Inventor: TAJIMA HIROYUKI
IPC: C01B3/06
Filed: 1978-03-14
Abstract: PURPOSE: To enhance the utilization efficiency of metal hydride by regulating the amount of H 2  generated according to the change in the consumption of H 2  and by preventing the occurrence of overpressure by the procedure in which supply water between inner wall and outer wall is vaporized to steam by means of a reaction heat produced when H 2  is generated by the reaction of the supply water with metal hydride.  
     CONSTITUTION: When supply water from th water tank 1 is flowed out of the nozzle 13 into the internal container 8, it reacts with CaH 2  coming near the nozzle 13 to generate H 2  and reaction heat. As the reaction heat builds up, the supply water in the space 11 is heated to water vapor, and the water vapor diffuses widely into the container 8 and undegoes reaction throughout the container, where the amount of H 2  generated varies with the amount of water vapor. Thus, the amount of H 2  generated varies with amount of consumed H 2 , and thereby the variation in pressure in the container 8 is reduced. With the build-up of reaction heat to a great extent, the pressure or water vapor in the space 11 is raised and water vapor of more than predetermined pressure is released from the safety valve 10.

Title: Heater with automatic temperature control
Inventor: TANABE MAKOTO
IPC: H01L39/16
Filed: 1988-02-12
Abstract: PURPOSE:To have an automatically temp. controlled heater with the number of parts reduced and in simplified control mechanism by connecting in series a plurality of oxide superconductor with different critical temps. CONSTITUTION:Resistance of each heater is represented by R, and the current by I. The critical temp. of heater 3-1 shall be 10 deg.C, 3-2 20 deg.C, 3-3 30 deg.C, and the heater 3-4 be -30 deg.C which is below normal service temp. This is to prevent the circuit from being broken, as the whole being put in superconductive condition at the time a switch 2 turned on should cause flow of a very large current. Because the whole is in normal conductive condition when the ambient temp. is 35 deg.C, the total resistance becomes 4R to present that I35=V/4R, P35=V<2>/4R. When the ambient temp. is 25 deg.C, on the other hand, only the heater 3-3 becomes in superconductive condition to result in a total resistance of 3R to present that I25=V/3R, P25=V<2>/3R. When the ambient temp. is 15 deg.C, 5 deg.C, in the same manner, it is presented that P15=V<2>/2R, P5=V<2>/R. That is, the amount of heat emission increases with lower ambient temp.

Abstract: PURPOSE:To enable efficient data communication for which an ISDN network is used when a line is connected by plural calls through plural routes. CONSTITUTION:After a propagation delay time difference detection part 25 decomposes the reception data received from an ISDN network 5 by a line interface part 22 into a time slot, the part 25 determines the propagation delay time difference of each time slot from the detection timing of the detection pattern inserted into each time slot and delivers these time differences to a synchronizing control part 24.
