Title: Inverter device
Inventor: ISHIGAMI TAKAHIRO
IPC: H02H7/122
Filed: 1988-05-17
Abstract: PURPOSE:To drive an induction machine satisfactorily by giving an interruption time to the switching elements in an overcurrent state corresponding to the carrier frequency of PWM modulation. CONSTITUTION:AC commercial power supply is converted into DC with a rectification circuit 1 and a voltage doubler smoothing circuit 2, and reconverted into AC again with switching elements 3u-3z of a power inverter 3 to drive an induction machine 4. These elements 3u-3z are controlled by the PWM signals of a PWM generation circuit 8. Current detectors 5x-5z are respectively connected inseries to elements 3x-3z. If decided as there exists an overcurrent condition by overcurrent deciders 6x-6z, 9x-9z are set and the output is inputted into a logic circuit 10. Differentiating circuits 11x-11z generate OFF timing pulses of the elements 3, which are inputted into a logic circuit 12. Thus, in the timing which enable the elements 3 to be turned ON again, the induction machine 4 can be driven without interruption, because the interruption time corresponding to the carrier frequency is given to the elements which are turned OFF due to the overcurrent.

IPC: H04W88/02
Filed: 1978-09-27
Abstract: PURPOSE:To enhance the impulse ratio of a battery saving circuit to make the life of a battery long by changing the proportion of call signals, which are transmitted from the base station to a mobile station, according to the proportion of call signals from the exchange. CONSTITUTION:In the base station, call signals from the exchange are detected by call signal detection circuit 3, and the output from call signal oscillation circuit 4 is transmitted to intermission circuit 6. Simultaneously, the output obtained by changing the time of the first call signal from the exchange by transmission time variable circuit 5 is transmitted to intermission circuit 6. In intermission circuit 6, the output of oscillation circuit 4 is made intermittent by the output of circuit 5 and is transmitted to mobile station 2. In the mobile station, when call signals from the base station are received by receiver 10, detection signals from call signal detection circuit 11 become output signals to supply power continuously from intermission circuit 14, which causes battery 13 to be intermittent, through power feeder 101. As a result, the impulse ratio of power supplied to the receiver required for detecting surely call signals in the mobile station can be enhanced.

Title: Electrophotographic apparatus
Inventor: HARA HIROSHI
IPC: G03G15/04
Filed: 1993-05-21
Abstract: PURPOSE:To prevent the deterioration of a photosensitive material and prolong the service life thereof by installing a current control means which controls electric supply from a current supply means to an emission element during exposure by turning the current on or off on the basis of printing data. CONSTITUTION:A controller drives a main motor by sending a main motor control signal to an engine controller (ST1). Exposure is judged whether it is based on printing data within a printing range or it is for leveling the surface potential of a photosensitive material drum other than printing (ST2). When the exposure is judged to be outside printing range, switching is conducted to a current source by moving the movable contact point of a switch (ST3), and emission to the photosensitive material drum is conducted with a switching element turned on (ST4). A printing process (pre-exposure, printing, post- exposure) by exposure is judged whether it is finished or not (ST5). If the process is judged to be not yet finished, the process returns to ST2, and if judged to be finished, the main motor is stopped to finish the exposure control action.

Title: Solenoid valve with thermal safety device
Inventor: MORI KOUJIROU
IPC: F16K31/66
Filed: 1980-08-29
Abstract: PURPOSE: To shift a valve member forcedly regardless of current supply to a solenoid by forming a return spring of the valve member with an amorphous metallic soft magnetic substance.  
     CONSTITUTION: When current is supplied to a solenoid 20 and a magnetic circuit is formed in the body 10, return spring 22 and plunger 19, this plunger 19 is energized and shifts to the right to drive the valve 17 apart from the valve seat 18 and thereby to put the valve chest 16 into communication with a through hole 13. Because an amorphous metallic soft magnetic substance forming a spring 19 at temperature for the measuring range is converted into a paramagnetic substance, energization of the plunger 19 by the spring 22 will cut the magnetic circuit even though the solenoid 20 is supplied with current, so that the plunger 19 is put out of energization to permit the spring 22 to press the valve 17 and seat it forcedly on the valve seat 18.
