Title: Bi-cmos logic circuit
Inventor: UNO TAKASHI
IPC: H03K17/04
Filed: 1987-10-06
Abstract: PURPOSE:To attain small load capacitance and to make the operation high in speed by connecting emitters of NPN and PNP bipolar transistors(TRs) in common as an output terminal and giving an output of a CMOS logic circuit to a base of the bipolar TRs. CONSTITUTION:When an output D of NAND gate FET M1-M4 is at a low level in normal state, the output D is substantially at a ground potential level with a sufficiently small base current and an output E also goes to a low level. When the output D of the NAND gate transits to a high level, the level of the CMOS(NAND) gate transits quickly to a high level because of its own load and the current supply to the base of NPN TR Q1 and PNP TR Q2, then the TR Q1 is forward-biased and turned on. Since the TR Q3 is in cut-off state, no current flows. Thus, the potential at the node E rises quickly. When the output of the NAND gate transits to a low level, the TR Q3 is forward-biased and the TR Q1 is cut off, the operation is similar to the case with the transition to the high level.

Filed: 1989-09-29
Abstract: PURPOSE:To avoid any cracking for stabilizing the resistance value by a method wherein a protective film comprising a CVD oxide film to avoid the autodoping in case of forming an epitaxial layer is formed on the sides and rear surface of a semiconductor substrate meeting the specific film formation requirements. CONSTITUTION:A protective film 2 comprising CVD oxide film is formed on the sides and rear surface of a P type semiconductor substrate 1. The substrate 1 is continuously shifted while being heated on a heated conveyer belt.

IPC: H03K17/725
Filed: 1985-11-11
Abstract: PURPOSE:To eliminate the need for a large sized power transformer to step down a commercial AC power voltage and to improve the safety by using a multivibrator and a small sized transformer connected to its output so as to make a voltage fed to an operation switch section lower. CONSTITUTION:A commercial AC power supply E is converted into a DC voltage (12V) by a rectifier diode D1, a smoothing capacitor C1 and a Zener diode D2. When an operation switch SW is turned off, a transistor (TR) 3 is turned on/off synchronously with the oscillation output of a multivibrator 1. A pulse voltage appearing at a collector of the TR 3 is smoothed by a smoothing circuit comprising a capacitor C4 and a resistor R5, a DC voltage of nearly 12V is applied to an anode of a PUT Q1, in which a TR 4 is turned on and a gate current is fed to a triac Q2 and a load L being an incandescent lamp is lighted. In turning on the operation switch SW, since the impedance of the primary side of the small sized transformer T is nearly zero, the TR 3, the PUT Q1 and the TR 4 are turned off and no gate current is fed to the triac Q2 and the load L goes out.
