Title: Clamping circuit
Inventor: MAKIHIRA HIROSHI
IPC: H04N5/16
Filed: 1982-09-01
Abstract: PURPOSE:To reduce the influence of noise and to realize a stable clamping, by deriving a mean level of a signal to be clamped, and clamping its level. CONSTITUTION:A picture signal is amplified by a buffer amplifier 1. A low- pass filter 8 converts a mean level of a blanking section of the picture signal to an output signal. This output signal is held in a sample holding circuit 9 by a sampling pulse 11. A differential amplifier 13 converts the difference of the picture signal and the sample holding output to an output signal. As for a method for deriving a mean value of the blanking section, a method by the low- pass filter 8 and also a digital means or a method by an integration circuit, etc. are available. To averaging, the influence of noise can be eliminated.

Title: Semiconductor relay
Inventor: SATE TOYOFUMI
IPC: H03K17/66
Filed: 1992-06-10
Abstract: PURPOSE:To realize a semiconductor relay not being a surge generating source with simple configuration when the relay is used for an AC power supply. CONSTITUTION:Diodes 9, 10 are in inverse-parallel connected to bipolar transistors(TRs) 7, 8 connected in inverse series between relay output terminals 3, 4. Then a series circuit comprising a resistor 13 and a capacitor 14 connected between bases and emitters of the bipolar TRs 7, 8 is energized from the relay output terminals 3, 4 through a photo thyristor 6 having a zero cross trigger function coupled optically with a light emitting diode 5 between relay input terminals 1, 2 and resistors 11, 12. Thus, the semiconductor relay used by an AC power supply is conducted in the vicinity of a zero cross point of an AC voltage and the relay does not become a noise generating source. Furthermore, since the path through which a main current flows is formed by a PN junction, the semiconductor relay of a large capacity is easily built up.
