Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To surely turn on a switching element on the secondary of a transformer when a main switch is turned off, by providing a gate voltage generating circuit which perfectly turns on/off a switching element for synchronous rectification. SOLUTION: A coil L1 is connected with the collector load of a transistor Q4 in a synchronous rectifier circuit and the voltage at the joint of the coil L1 and a resistor R2 is applied to the gate G of an FET Q3 as a signal for turning it on/off. A resistor R1, the transistor Q4, the coil L1 and the resistor R2 constitute a gate voltage generating circuit 10 and the coil L1 is connected for driving a communication FET Q3. When a main FET Q1 is turned off, the transistor Q4 is turned off to discharge energy stored in the coil L1 to the resistor R2 and the commutation FET Q3 is turned on with the gate-source voltage induced by a generated voltage. The switching element can thereby be turned on surely when the main FET is turned off.

Title: Memory initial setting system
Inventor: YAMAZAKI GINZOU
IPC: G06F1/00
Filed: 1979-11-26
Abstract: PURPOSE: To ensure an automatic execution for both the initial setting to a volatile memory and the preservation of data to a nonvolatile memory, by discontinuing the initial setting to the volatile memory when the boundary address is detected between the volatile and nonvolatile memories.  
     CONSTITUTION: The boundary address is set previously to the address setting device 104 between the volatile memories 102A/102B and the nonvolatile memories 102C/102D. The CPU101 gives an initial setting to the volatile memory in the fixed timing. In this case, the program counter 201 shows the address of the memory to receive the initial setting. Then a comparator 203 is given between the designated address of the counter 201 and the set address of the device 104. Receiving the coincidence signal, the CPU101 discontinues the subsequent initial setting actions and starts the normal job thereafter. Accordingly, the initial setting is given only to the volatile memory, and the data stored by the precedent process is preserved in the nonvolatile memory.

Title: Drive controller in hybrid vehicle

IPC: B60L50/16
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To prevent a transitory decrease in driving torque and a feeling of deceleration caused thereby when an engine is put in an idling state and a creep running state is shifted to an accelerated state using an assist motor. SOLUTION: When an internal combustion engine is put in an idling state and a creep running state assisted with output torque of a motor is detected by a creep running detecting means (step 021), the revolutions of an engine should be increased on the basis of a demand of an increase in driving force in the running state. In this case, a torque command value for controlling the output torque of the motor and increasing the revolution of the engine is so controlled that the torque command value is not smaller than that of the running state under a given reference condition, and then a decrease in demand of driving force can be prevented by the electric motor torque controlling means (step 030).
