Title: Hydrogen producing device
Inventor: KONDO YUMITO
IPC: C01B3/38
Filed: 1989-06-29
Abstract: PURPOSE:To reduce the start-up time of the entire reforming line by combining the raw gas feed line, vapor generating line, air feed line, reformer, produced hydrogen delivery line, reformer waste combustion gas line and further the CO converter jacket, branch pipe and switching valve for a specified action. CONSTITUTION:The branch pipe 6A branched from the branch point of a switching valve 5 is allowed to communicate with a desulfurization reactor jacket 13 provided around the catalyst of a desulfurization reactor 1. When the device is started up, the reformer waste combustion gas is introduced into a turnout 6A from the switching valve 5 and passed through the jacket 13 to heat the reactor 1. The reactor 1 is heated in a relatively short time when started up with the waste combustion gas without consuming power for an electric heater, and the start-up time of the entire device is reduced. Furthermore, since the heat of the waste gas leaving the jacket 13 is recovered by an air preheating heat exchanger 4, the heat is efficiently recovered even in the start-up.

Abstract: PURPOSE:To provide a pressure sensitive sensor with a very high sensitivity and presenting a high reliability which converts the received pressure directly into an electric signal through deformation of liquid and eliminating any power supply for in advance impressing a voltage on the electrode. CONSTITUTION:A pressure sensitive element concerned comprises a vessel 1 which accommodates liquid 3 and is deformable with the received pressure, a porous body 2 which is installed in the vessel 1 and admits passage of the liquid 3, and a pair of electrodes 4, 4 which are installed on both surfaces of the porous body 2 and induce an electromotive force when the liquid 3 passes the porous body 2. When pressure acts on the vessel 1, the liquid 3 in the body 2 moves within it in the direction of pressure application to cause electromotive force to be induced between the electrodes 4, 4. This may be used also as a liquid nature element owing to existence of the porous body 2 and electrodes 4, 4.

Filed: 1989-06-29
Abstract: PURPOSE:To automatically select a retiming signal independently of the repeating frequency of an inputted data signal by constituting a circuit with a 1/3 frequency dividing circuit, a phase comparator and a selector. CONSTITUTION:A master clock signal 103 is subjected to 1/3 frequency division by a 1/3 frequency dividing circuit 107, from which 1/3 frequency division clock 1071-1073 (PHI0-PHI2) whose phase differs by 2pi/3 each are generated. When a phase comparator 108 decides that the change point of an output signal of a 1/2 frequency dividing circuit 106 is between the clock rises of the clock signals PHI0 and PHI1, the clock signal PHI2 is selected by a selector 109. Moreover, a latch circuit 111 applies retiming to the output signal of a latch circuit 110 in the timing of the output signal of the selector 109 without error, an data signals 1121-1123 synchronously with the phase of the master clock signal are outputted. Thus, the retiming signal is selected automatically independently of the repeating frequency of the inputting data.

Title: Fuel battery with molten carbonate
Inventor: FUJITA YOJI
IPC: H01M8/02
Filed: 1988-07-05
Abstract: PURPOSE:To keep a battery electrode for a long period of time by actuating a chemical change which generates Li2CO3 to cause variation in the ratio of lithium to other elements, and by carrying Li-containing composite oxides which refills Li2CO3 into electrolyte. CONSTITUTION:Electrolyte in an electrolytic layer is decreasing through reaction with a gas chamber component member 10 on the air electrode side. On the air electrode 12 side consisting of NiO porous body wherein LiFeO2 is doped, one of the major factors for wear of electrolyte is reaction of Li2CO3 with iron oxides. Li2CO3 is consumed selectively, and the Li/K ratio in the electrolyte transfers from initial value of 62/38 to a small value. With decreasing Li/K ratio, the LiFeO2 carried previously in the air electrode 12 emits Li2CO3 while reacting with CO2 in the air electrode side gas, and this is refilled into the electrolyte with the Li2CO3 worn, and at the same time, the Li/K ratio is kept constant and the battery characteristic prevented from dropping.
