Title: Hydraulic source device
Inventor: ONISHI KUNIMORI
IPC: F04B23/02
Filed: 1990-09-28
Abstract: PURPOSE:To improve the efficiency of operation with a compact tank by disposing vertically a partition plate on the side of a motor disposed on the downstream side of a position of a return path member opened to a flow path and disposing an intake port of a hydraulic pump on the downstream side of the flow path in which the motor is disposed. CONSTITUTION:When a hydraulic pump 3 is driven by supplying current to a motor 2, working liquid in a tank 1 is discharged from the hydraulic pump 3 through an intake pipe 15 to a joint block member 8. Hydraulic actuator receiving the discharged working liquid is operated to circulate the working liquid from the joint block member 9 through a return piping and return path member 11 into the tank 1. Operating sounds are attenuated by the working liquid and the propagation of the operating sounds is interrupted and attenuated by partition plates 12A, 12B. The working liquid circulating from a return port 11A of the return path member 11 into the tank 1 is sent from a flow path 13A to flow paths 13B, 13C in the tank 1 to be sucked by the hydraulic pump 3. The motor 2 is disposed in the flow path 13B and the working liquid actively flows around the motor to cool it.

Title: Mos type semiconductor integrated circuit
Inventor: TAMURA TAKESHI
IPC: H03K19/00
Filed: 1986-11-04
Abstract: PURPOSE:To prevent an excessive shorting current at a high voltage source side when a low voltage source is an intermediate level and stable by putting serially a transistor between a next step a GND and adding the input signal of a level shift and the signal of inversion to a gate. CONSTITUTION:An Nch transistor 1 is connected between an inverter 5 and GND, the input signal of a level shifting circuit 4 and the signal of the opposite phase are given to the gate of the transistor 1 and like that, the gate signal of an inverter 3 is inputted. The conditions, in which the output signal of a level shifting circuit does not come to be stable, occur only when an Nch transistor 13 is turned on. The Nch transistor 1, since the signal of the phase opposite to the transistor 13 is inputted, is turned off then. Consequently, even when the gate signal of the inverter 5 does not come to be stable, the channel is cut in which a shorting current flows at the inverter 5 itself. Thus, when a low voltage system voltage is stable at the intermediate level, an excessive shorting current to flow at the high voltage system can be eliminated.

Title: Controller for energy-generating-means mounted electric vehicle
Inventor: EGAMI TSUNEYUKI
IPC: B60L50/10
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To improve the acceleration performance and the power regeneration performance of a car by controlling the target charging level of a charging means so as to decrease it when the car speed is high, and to increase it when the car speed is low. SOLUTION: First, the value of a vehicle speed obtained this time from a vehicle speed sensor is read (S1030), and an average vehicular speed Vm is computed by averaging a large number of vehicular speed values read in a specified period T immediately before it (S1032), and a target charging level pbp is determined from a map according to the computed average vehicular speed Vm (S1034). Furthermore, a present charging level pb is found from an SOC meter (S1036). Next, a required battery power value pb' which is the difference between a target charging level pbp and the present charging level pb found is computed (S1038), and returns to a main routine.  Consequently, it becomes possible to perform large power regeneration at high-speed times and to perform strong acceleration at low-speed times, since a charging level is decreased when the vehicular speed is high, and a charging level is increased, when the vehicular speed is low.
