Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To increase starting power of the actuator simply by fitting a fluid system to the forward stage of an input port of the actuator. SOLUTION: In the initial movement of a piston 2 from the initial position, pressure in a primary pressure room 31 is intensified and generated in a secondary pressure room 32 by the difference of areas of a large diameter end 21a of the piston 2 and a small diameter end 22a of the piston 2 and the fluid of the secondary pressure room 32 is outputted to an output port 92, while, during the piston 2 is proceeding to the final end position after passing through a switchover position, a bypass path 61 makes the primary pressure room 31 communicate with the secondary pressure room 32 and acts to output the fluid in the primary pressure room 31 as it is.  An actuator with improved starting power can be obtained with such simplified composition because pressure higher than the system pressure can be automatically supplied to the actuator, when the actuator is started, by guiding the system pressure to the primary pressure room 31 and the secondary pressure room 32 is communicated with the actuator.

Title: Hybrid vehicle
Inventor: KUMAKURA HIROTAKA
IPC: B60L50/16
Filed: 1992-11-16
Abstract: PURPOSE:To suppress exhaust of harmful components by deciding a schedule of an engine speed and a load based on a catalytic temperature, and controlling the operations of the engine and a generator based on the schedule. CONSTITUTION:A temperature sensor 23 detects the temperature of a catalyst and inputs a temperature signal to an engine controller 10. The controller 10 controls the operation of an engine 1 immediately after starting based on the input temperature signal. That is, the speed of the engine 1 is gradually increased from a low level until warm-up of the catalyst is finished. The charging quantity of a battery 4 is controlled through a charge quantity controller 11 to gradually increase the load of the engine 1 from a low level. Thus, after the engine 1 is started, the engine speed and load are suppressed to low values, and the engine 1 and the generator 2 are so controlled as to gradually increase them as time is elapsed. Thus, exhaust of harmful components can be suppressed.

Title: Circuit and method for re-establishing phase current
Inventor: KENESU EI BERINGAA
IPC: H02M7/5387
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To protect a power supply switch in each phase bridge from an excess current, and give a microcontroller sufficient data for suitably controlling a motor. SOLUTION: A phase current reconstructing circuit 10 detects and reconstructs a phase current in a phase bridge 12A. Amplifiers in phase current reconstructing elements 22a-22c amplify voltage signals of both ends of detection resistors 18a-18c, and transmit the signals to a sample-and-hold circuit, in which a phase current in the phase bridge 12A is reconstructed. An excess current comparator compares the amplified voltage signal with a reference voltage, and detects the excess current in the phase bridge 12A. When the excess current is detected, an excess current latch blocks a pulse width modulation signal from a microcontroller 26 to a power supply which 16A in the phase bridge 12A, and the switch is turned off. Thereby the power switch 16A is protected from damage due to an excess current.

Title: Injector driving circuit
Inventor: YASUI TAKUYA
IPC: F02M51/00
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent a reduction in off-speed of the solenoid of an injector to prevent a reduction in injection characteristics of the injector. SOLUTION: At a point of time when the lean-rich signal from an oxygen sensor 17 begins to repeat lean and rich, a control signal generating part 14 gradually reduces a reference voltage so that holding current is changed from I1 →I2 →I3 →I4 (I1 >I2 >I3 >I4 ). An injector is thus ON up to a necessary time, and when the injector is quickly OFF with Lower than a holding current limit value LLMT when the holding current is then set to I4 , the lean state is formed. When the lean-rich signal at that time is inputted, the control signal generating part 14 judges the I3 just before the time when this lean state is held as a truly necessary minimum holding current, sets the holding current to I3 , and applies the reference voltage (reference signal) to a holding current supplying circuit 9 on the basis of the I3 .
