Patent KR-850000734-B1 (KR)
Title: Variable load impedance gain-controlled amplifier
Inventor: HARFORD JACK RUDOLPH
IPC: H03G1/00
Filed: 1981-04-22
Granted: 1985-05-23
Abstract: The transistor television intermediate frequency amplifier has variable gain controlled by automatic gain control current feedback. A transistor is biased in a common emitter mode with signals fed into the base junction and output taken from the collector. The collector has a variable impedance load formed by the base and emitter of a second transistor. Feedback current fed into the emitter of the second transistor flows to ground through the collector but alters the base emitter impedance and hence the gain of the amplifier. Two amplifiers with a common feedback current may be connected as a variable gain differential amplifier.

Title: Power converter
Inventor: ANDO DAKEKKI
IPC: H02P7/292
Filed: 1983-03-09
Granted: 1990-05-19
Abstract: The converter connects GTO elements to the positive arms of a three- phase full wave bridge circuit and repeats the mode of supplying power to a load from an ac power supply by controlling the GTO elements. The mode of making the current flowing to the load flow back at the time of interruption of the power supply mode is repeated when the power supply mode and the flow-back mode are switched over. Overvoltage at the time of the switching is suppressed by simultaneously causing the power supply and flowback currents to flow.

Abstract: The method for growing an oxide film of the  CMOS  integrated device is characterized by implanting  O2  gas  into  the  silicon wafer at 700-1200 deg.C and 1 l/min velocity, implanting O2 gas at 1200 deg.C and 1 l/min velocity, heat-treating it for 5 hr to form a no-flaw region, implanting O2 gas and tetrachloroethene (TCA) at 1200  deg.C,  7.5  l/min  (O2  gas)  and  215  cc/min  (TCA),  and heat-treating it for 70 min to form the oxide film.
