Patent KR-900005603-B1 (KR)
Title: Chrominace signal processing device
Inventor: MATSMOTO TOKIKATS
IPC: H04N9/68
Filed: 1985-06-08
Granted: 1990-07-31
Abstract: The system has a variable gain amplifier (11) for gain control of a carrier chrominance signal. An A/D converter (12) effects A/D conversion of the output of the variable gain amplifier. The output of the A/D converter is demodulated (13) into chrominance difference signals (R-Y,B-Y). A circuit (15) computes the amplitude of the burst signal of the carrier chrominance signal from the two chrominance signals. A control circuit (21) produces a signal for controlling the gain of the variable gain amplifier from the computing circuits output. A demodulater has two different demodulation axes for producing the two chrominance difference signals with 90 degrees difference. One demodulation axis is at right angles with the burst signal vector.

The properties of the polymeric membrane of the microballoons (elasticity, permeability, biodegradability) can be controlled at will depending on the selected polymer, the interfacial deposition conditions, and the polymer additives.
