Title: Read control circuit
Inventor: IKEDA YOSHINOBU
IPC: G06F11/10
Filed: 1984-10-08
Abstract: PURPOSE:To simplify the initialization procedure and minimize the initialization time by providing the means to change the display of unstored of parity matched data to the display of 'toring' of parity matched data, when storing the data. CONSTITUTION:A register 4 is storing the parity matched data immediately after the power is turned on or at the time of reset. Address information is read from a memory 1, decoded by a decoder 14 and inputted to AND gates 9 and 10. When the address information specifies the address to No.1, the first output of the decoder 14 is '0', and the output of the gate 9 is also '0'; and the second output of the decoder 14 is '1', and it is inputted to the gate 10. Another input to the gate 10 is supplied from FF7, but as immediately after the power on or reset FF7 is reset and outputting '0', the output of the gate 10 becomes '0'. Therefore, the switching signal, which is outputted from OR gate 11 is also '0'. In this case, therefore, a multiplexer 5 selects the contents of a register 4, and outputs to a data bus 6.

Title: Heat exchanger for reformer of fuel cell generator
Inventor: ROBAATO MISAGE
IPC: H01M8/04
Filed: 1988-08-26
Abstract: PURPOSE: To eliminate a necessity for arranging an auxiliary heater to energize a power generator by a method wherein three different flow passage cores are stored in a single housing and all these flow passage cores are thermally connected to each other by heat exchanging fin plates. CONSTITUTION: Hydrocarbon fuel of raw material to be pre-heated passes through a conduit 58 into a heat exchanger 2 and is not only heated by discharged gas from a catalyst reforming device passing through a central core section 14, but also heated by cooling water flowing from a power generator fed from the conduit 28. Then, when the power generator is energized, the heat exchanger 2 is pre-heated with cooling water of high temperature flowing through the pipe 34. This cooling water is sufficiently heated when the fuel cell is energized, the lower half mass of the core section 14 is heated sufficiently more than a dew point of the initial discharged gas flowed from the reforming device and similarly, the upper half mass of the core section 14 is sufficiently pre-heated by the discharged gas and each of them is prevented from being coagulated.  It is not necessary to arrange any heater for pre-heating and adjustment of the heat exchanger 2.

Title: Calorimeter
Inventor: MUTO HIROYUKI
IPC: G01N27/18
Filed: 1994-09-05
Abstract: PURPOSE: To make the effects of fluctuations of environments and gas hard to receive, and measure a heating value of the gas continuously by providing a thermal conductivity measuring means and a heating-value computing means, and performing the measurement of the thermal conductivity. CONSTITUTION: When the thermal conductivity of gas to be measured is changed, a voltage applied on a circuit is changed so as to keep a heating temperature TRh (also a resistance value Rh) of a temperature measuring resistor 1 constant. A thermal conductivity λm, which is computed with a thermal- conductivity computing part 4 based on the change in applied voltage, is used, and the heating value of the gas to be measured is computed based on the relationship of the heating value H=-549.7×λm+35562.9 in a heating-value computing part 5. That is to say, a heating value of the gas to be measured can be obtained by measuring the thermal conductivity. Here, the value of the thermal conductivity under the pressure range of the degree of the atmosphere is hardly changed. In the normal case, the measurement is performed in a constant temperature oven.  Therefore, the effects of the fluctuations of the environments such as temperature and the gas are hard to receive, and the heating value of the gas can be continuously measured.
