Filed: 1983-04-15
Abstract: PURPOSE:To ensure the correct input of an AC signal even without using a smoothing circuit by feeding the AC input signal to a voltage detecting circuit only when the instant value of the AC input signal is set at the maximum level. CONSTITUTION:The output of an AC signal power supply 1 is supplied to an input terminal 7a of a voltage detecting circuit 7 via voltage dividing resistances 3 and 4 after undergoing the full wave rectification through a rectifying diode 2. While the output of a diode-stat 2 is supplied to a delay pulse generating circuit 9 which generates pulses with a time delay of 1/4 cycle of the power supply 1 via a zero voltage detecting circuit 8. The maximum value (crest value) of an input signal is detected from the circuit 9 and then applied to an input terminal 7b of the circuit 7 as an input timing signal. The circuit 7 accepts the input from the terminal 7a only when the output signal of the circuit 9 is delivered. Thus the AC signal can be fed correctly even without using a smoothing circuit.

Filed: 1987-03-23
Abstract: PURPOSE:To equalize acquisition of the using right of a channel and to evade the adverse influence due to the fixed using right of the channel, by exchanging the priorities between blocks of the same level as well as between two processing requests including a block of a basic level. CONSTITUTION:For four channels CH0-CH3, the CH0 and CH1 form a level-1 block 11 and the CH2 and CH3 form a level-1 block 12 respectively. Then the CH0 is used by a request and the priorities are exchanged between blocks 11 and 12. In addition, the CH0 and CH1 are switched with each other within the block 11. When the CH2 having the highest priority is used, the blocks 11 and 12 are switched with each other together with switch of channels carried out within the block 12. In such a way, the priorities are successively switched with use of channels of higher priorities so that the acquisition of channel using right is equalized and the adverse influences due to the fixed using right of channels can be evaded.

Title: Trace for branch instruction
Inventor: SEKIMOTO KOJI
IPC: G06F11/28
Filed: 1989-03-17
Abstract: PURPOSE:To improve the storage efficiency of a buffer for tracing by gathering only effective information without storing the repetition of unnecessary data in the buffer for tracing. CONSTITUTION:Every time the branch instruction is executed, a comparator 17 compares the contents of a save address register 3 which are data to be traced with the contents of a trace copy register 6. When the comparison result of the comparator 17 shows a coincidence, '000' is set in a trace address low- order register 51. Consequently, the storage address of the buffer 4 for tracing is returned and next trace data is overwritten on trace data which is stored in this range. When the comparison result of the comparator 17 does not show the coincidence, the value of the save address register 3 is stored in the buffer 4 for tracing. Consequently, data is prevented from being stored repeatedly and the buffer for tracing can be used effectively.

Title: Fuel cell power generation system
Inventor: AMAMIYA TAKASHI
IPC: H01M8/04
Filed: 1985-03-30
Abstract: PURPOSE:To achieve improved operation efficiency of a fuel cell power generation system by minimizing the time required for restarting the system and restoring the state of power generation after emergent suspension of the operation of the system by providing the fuel reformer with a second combustor in which a fuel combustion air introduced from other systems are combusted. CONSTITUTION:When the operation of a power generation system is emergently suspended, a valve 23a is opened and a valve 11a is closed to stop combustion in a main combustor 7. While valves 8a, 12a and 24a are closed to maintain the internal pressure of a fuel reformer 4, combustion is performed in a second combustor consisting of a pilot combustor 6. The flow rate of a fuel supplied into the pilot combustor 6 is controlled by a valve 6a. Combustion air is supplied from an external air source through a valve 27a for controlling the flow rate. By thus continuing combustion in the pilot combustor 6 while maintaining the internal pressure of the fuel reformer 4, the internal temperature of the fuel reformer 4 is maintained high. Consequently, the time for restarting the system and restoring the state of power generation after emergent suspension of the operation of the system is greatly reduced.

Title: Method to control flow rate of heat exchanger
Inventor: OKAZAKI MAKOTO
IPC: F28F27/02
Filed: 1985-03-30
Abstract: PURPOSE:To control the flow rate of each flow path with total flow rate always being maintained at a constant, by changing the flow rate except a specific one, as well as to change the flow rate of specific flow path, when the outlet temperature in specific flow path exceeds and become dissociated from a predetermined range of temperature around average temperature. CONSTITUTION:The deviation among average outlet temperature of each flow path 12-1, 12-2 and 12-3 and actual outlet temperature of each flow path is always monitored. When even one among the flow paths 12-1, 12-2 and 12-3 exceeds the predetermined range of gap, a value to change the setting value of accompanying other flow paths is calculated without changing the total value of whole flow rate, and a value to set fresh flow rate is given to each flow rate regulator in order to give the same effect as to change a setting value by giving a predetermined fixed rate to the specific flow path. In such a manner the flow rate of each flow path is controlled, by changing the flow rates of other flow paths as much as possible to correct the increased rate of specific flow path, when the flow rate needs regulating as the temperature in the specific flow path has changed.
