Title: Overvoltage inhibition circuit of capacitor
Inventor: DOBASHI HIDEYOSHI
IPC: H02M7/48
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To easily detect the failure in the charge circuit of a capacitor without using any expensive DC voltage detectors or DC current transformers. SOLUTION: In a conventional circuit where the series circuit of a discharge resistor 11 and a discharge transistor 13 is connected in parallel with a smoothing capacitor 3, and a capacitor voltage detector 14 gives an ON command to a base drive circuit 20 when a first setting voltage is exceeded and gives an OFF command to it when a second setting voltage cannot be exceeded, the presence or absence of the voltage between the collector and emitter of the discharge transistor 12 is detected by a voltage-dividing resistor 23, and the presence or absence of the voltage and the ON/OFF commands are given to a logic circuit 21.  A logic circuit 21 judges to be abnormal and abnormal when the voltage of the voltage-dividing resistor 23 exists or is equal to zero, respectively, when the ON command is issued, and judges to be normal and abnormal when the voltage of the voltage-dividing resistor 23 exists and is equal to zero, respectively, when the OFF command is issued.

Title: Control device for hybrid vehicle
Inventor: FUJIKI HARUO
IPC: B60L50/16
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To enhance the torque of a driving motor without over-discharging a battery even if the current carried out from the battery exceeds an allowable discharge current by an increase in load in the drive of the driving motor by use of the battery. SOLUTION: The actual current Ib of the battery is compared with an allowable discharge current upper limit value K-Ibh (S5). When the actual current Ib exceeds K-Ibh, a target engine torque Tet is calculated on the basis of operating state, and a command signal corresponding to the target engine torque Tet is transmitted to an E/G-ECU for controlling the torque of an engine (S11). In the E/G-ECU, the engine 1 is driven and feedback controlled so that the engine torque is the target engine torque Tet, a generating motor directly connected to the engine 1 is operated for generation, and the generated power is supplied to the driving motor (S11). Consequently, the shortage of the battery current is covered by the power from the generating motor.

Title: Air compressor
Inventor: ISOBE EIJI
IPC: F04B39/00
Filed: 2000-03-24
Abstract: PROBLEM TO BE SOLVED: To provide an air compressor with a simple structure and in low costs. SOLUTION: Since a piston 3a and a connecting rod 3b are integrated with each other and the connecting rod 3b is rotatably engaged with an eccentric position of an eccentric member 2 fixed to a rotary shaft M1 of a driving motor M, the piston 3a is moved in reciprocation while swinging. Since the rotary shaft M1 is eccentrically offset with an axis L3 of an inner circumferential wall 6a of a cylinder 6, air in a pressure chamber 7 is compressed by the piston 3 with reciprocating motion, and also a clearance S is generated between the piston 3a and the inner circumferential wall 6a only at the time of an intake stroke. It is thus possible to eliminate an intake valve at the time of the intake stroke.  Since the piston 3a and the connecting rod 3b are integrated with each other, this device is manufactured with a simple structure and in low costs in the case where, for example, it is formed by means of die-cast molding or resin molding.
