Abstract: PURPOSE:To improve the convenience of use by sending a video signal with in-frame coding processing just after a line is connected. CONSTITUTION:In the case converting a video signal SV into a digital signal and applying the coding processing to the signal, after a logic level of a control signal SCONT rises, the in-frame coding processing is selected for a prescribed period by a video signal transmitter 10 to process a picture data.

Title: Inverter
Inventor: USUI HIROSHI
IPC: H02M7/48
Filed: 1995-03-07
Abstract: PURPOSE: To obtain a small-sized, lightweight high frequency inverter. CONSTITUTION: When an overcurrent flows through the reactor 6 and the output capacitor 7 in a filter circuit 46 due to overload, for example, the overcurrent is detected, in the form of a corresponding voltage, by means of first and second current detection resistors 51, 52 connected in series with first and second MOS- FETs 2, 3. When the detected voltage exceeds a predetermined level, first or second overcurrent protective means 53, 54 interrupts the ON/OFF operation of first or second MOS-FET 2, 3. Since the first or second overcurrent protective means 53, 54 has high response rate, a high frequency inverter can be realized easily. Furthermore, the size and weight of inverter can be reduced because a small-sized, lightweight first or second current detection resistor 51, 52 can be employed as a current detection means.
