Title: Bridge-type inverter circuit
Inventor: SUZUKI SADANORI
IPC: H02M7/5387
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To provide an inverter circuit which especially uses a single drive power supply and is capable of being driven at a high frequency. SOLUTION: While FETs 21 and 24, 22 and 23 are being alternately switched by upper and lower FET switching signals L, R, high-frequency switching is conducted by high-frequency drive signals. For example, while the FETs 22, 23 are being turned on, a high-frequency driving signal F is supplied to transistors 31, 32 via an OR gate 30 to alternately turn on and off the transistor 31, 32, and the FET 22 is thereby driven at a high frequency. Furthermore, while the FETs 21, 24 are being turned on, a high-frequency drive signal F is supplied similarly to the two transistors via the OR gate to alternately turn on and off the two transistors, and the FET 24 is thereby driven at a high frequency. By adopting such a configuration, power based on high-frequency drive is supplied to an alternating-current load.

Title: Video camera
Inventor: KINUGASA TOSHIRO
IPC: H04N5/16
Filed: 1985-05-02
Abstract: PURPOSE:To simplify the adjustment procedure by suppressing automatically shading. CONSTITUTION:When shading exists in video signals 4, 5, a detector 6 detects the magnitude (VE-VS) of the shading, and a sawtooth wave having an amplitude proportional to the magnitude of the shading from a sawtooth wave generator 7 is subtracted from the video signal by a subtractor 8. The video signal 5 is outputted as a video signal (c) without shading by a feedback loop comprising the detector 6, the sawtooth wave generator 7 and the subtractor 8. Thus, it is possible to suppress automatically the shading at the dark state to simplify the adjusting procedure.

Filed: 1978-08-02
Abstract: PURPOSE:To simplify the construction and operation by changing the operations of an electronic circuit in accordance with the contacting time between the electronic circuit and a contact portion which is coactive with an externally actuating member. CONSTITUTION:When a battery voltage reduction detecting unit 8 predicts a malfunction, an externally actuating member 5 is actuated to operate a timer or counter 6. Then, in case the contacting time is an input shorter than a timer preset time, a frequency-dividing circuit 2 is not reset, but a subsequent timer of counter 7 is operated to generate such an output as subsequently operate a battery life control circuit 9. When a longer time signal input that the preset time of the timer 6 continues, this timer 6 reset the frequcncy-dividing circuit 2. In the case of the normal battery voltage, therefore, it is only when a winding stem is brought into contact with a single time resetting pin that a second hand can be advanced twice for a step shorter than 1/10 secong in a similar manner to that when the voltage is lowered. Thus, the actuation from the outside can be simplified.
