Patent JP-S5816311-A (JP)
Title: Electric power controlling circuit
Inventor: INOUE YUKIO
IPC: H02M5/257
Filed: 1981-07-22
Abstract: PURPOSE:To realize an assured control of electric power even though the resistance of load is unstable, by giving a control so as to ensure the even effective value for the electric power of a commercial power supply for each half wave. CONSTITUTION:A gate turn-off thyristor GTO is put into a load circuit that supplies the electric power to a load R through a commercial power supply E. The power supply voltage (ei) is fed to a zero cross detecting circuit 1, and the zero cross is detected for each half wave. Then a turn-on gate pulse is delivered. At the same time, the output voltage (eo) and a current (i) are fed to an effective value arithmetic circuit 2 to obtain the effective value of electric power to the load R. This effective value is converted 3 into a frequency and counted by a counter circuit 4 for each half wave. This count value is compared 5 with the target value, and a turn-off pulse is delivered when the coincidence is obtained. Thus the effective value of electric power is made even for each half value. As a result, the electric power can be controlled assuredly even though the resistance of the load is unstable.

Title: Hydraulic actuator
Inventor: ISHIDA HISAO
IPC: F15B15/06
Filed: 1983-06-24
Abstract: PURPOSE:To prevent a gear sound and the time delay of synchronization, by providing pistons, which are arranged oppositely facing to each other, in actuators and actuating an internal lever by these pistons. CONSTITUTION:The first actuators 2, 3 are formed by a pair of cylinders 21, 31 and pistons 23, 33 which are arranged oppositely facing to each other. An internal lever 4 is mounted to the pistons 23, 33 by a pin 5 so that the internal lever 4 may be actuated by the pistons 23, 33. In this way, a gear sound due to excessive control power in one direction or the time delay of synchronization due to too little control power and the like can be prevented because a device, when it is used as the actuator for speed change control, equalizes its operating force in both directions.

Filed: 1995-05-12
Abstract: PURPOSE: To set selectively transmission of image data of destination information by providing a means setting a transmission condition of read destination information. CONSTITUTION: A number transmission mode switch in an SRAM 76 being a transmission condition setting means selects either a level '1' indicating transmission of image data read for recognizing destination condition as part of transmission data or a level '0' indicating no transmission of the image data. A CPU 60 discriminates whether or not the number transmission mode switch is set to '0', and when '1', the image data of the destination information stored in a line buffer in an SRAM 7 are sent according to the set transmission mode. On the other hand, when the number transmission mode switch is set to '0', image data obtained by reading other areas than the area of the destination information of the transmission original are sent. Thus, the destination information is sent to an opposite facsimile equipment as required.
