Title: Automatic power factor adjusting device
Inventor: HAYADE SATOO
IPC: H02J3/18
Filed: 1982-03-05
Abstract: PURPOSE:To ensure the automatic and continuous control of power factor, by detecting the reactive power with an AC double phase servo motor and driving a single phase IVR with the rotary torque of the servo motor to control the output voltage and the compensating power. CONSTITUTION:The voltage is induced to a control winding l3 of a transformer 22 in response to the applied voltage and then applied to an input terminal of a IVR23. With application of this voltage, the voltage having the same phase and same level as that of the input side is induced at an output terminal and then applied to a control winding l4 of the transformer 22. As a result, the primary magnetic flux of the transformer 22 is controlled by the control magnetic flux generated by the energization of the winding l4, and accordingly the induced voltage by a secondary winding l2 is controlled. The energized voltage of the winding l4 is varied by the operation of a servo motor 24. The rotary torque of the motor 24 is proportional to the reactive power of the system. Thus the induced voltage of the winding l2 increases as the reactive power increases to increase the compensating power.

Title: Binary coding circuit
Inventor: INOUE TAKESHI
IPC: H03K5/08
Filed: 1982-03-05
Abstract: PURPOSE:To realize stable binary coding which is not affected by the level variations of illumination, the shading characteristics of an image pickup device, etc., by switching binary-coded signals when the change of signal level exceeds a fixed level. CONSTITUTION:The binary coding is carried out with a fixed threshold value T until the 1st binary coding switch point A, and the floating threshold value T' is used at and after the point A. When the binary coding level is 1, the value T' is decided to a level that is lower than the maximum value P1 by the prescribed set value V1 until the next switch point B. This value T' is not fixed and rises up with the rise of an input video signal g(t). Then the point B is used as the binary coding switch point in case the signal level drops. In such a way, the value T' is defined as the threshold value and then switched as a binary coding level. Thus a binary-coded signal that is approximate to an ideal form can be obtained as shown by the diagram.
