Abstract: PURPOSE:To suppress a luminance change in upper and lower non-picture portions in a current receiver suppressing the occurrence of a V sag being a cause for deteriora tion in picture quality, receiving and reproducing the signal of a letter box system or an intermediate system. CONSTITUTION:A vertical compression section 4 on a transmitter side compresses a wide aspect pattern so as to be reproduced even by a current receiver.

Title: Integrated circuit
Inventor: NAKAMURA MASAHIRO
IPC: H03K19/00
Filed: 1986-08-04
Abstract: PURPOSE:To prevent malfunction due to a change in an output signal by installing a delay circuit at least on one input side among output buffer circuits in terms of an integrated circuit including plural output buffer circuits. CONSTITUTION:The titled circuit is constituted of the output buffer circuit 2 which directly receives a signal S1 out of two internal signals S1 and S2 changing at the same clock timing, and the output buffer circuit 3 receiving the signal S2 through the delay circuit 6. Even if the potentials of the signals S1 and S2 change at the same clock timing, the delay circuit 6 prevents the potentials of output terminals 4 and 5 from changing simultaneously. This means that the potential of the output terminal 5 changes in 4 DELTAT after the potential of the output terminal 4 has changed. Therefore, a power source in the CMOS integrated circuit and the potential of a GND wiring change less. As a result, the influcence of the output buffer circuits upon an input level can be minimized. Said DELTAT denotes the gate delay time of an inverter comprising inverters I1-I4 and the circuit 6.

Abstract: PROBLEM TO BE SOLVED: To provide an amplifier circuit which raises the clip start voltage to suppress the frequent occurrence of distortions caused by the clipping and can cope with the large output by connecting directly the collector of an NPN type transistor TR to the high voltage. SOLUTION: When the output voltage of an amplifier 11 has a level lower than the reference voltage, a driver TR Q15 and also a power TR M11 are turned off and low voltage VccL is supplied to the collectors of TR Q11 and Q12 of the final output stage of the amplifier 11 via a diode D11 as the power voltage.
