Filed: 1984-07-24
Abstract: PURPOSE:To detect the defect of a bidirectional switch element over the entire cycle by respectively detecting the positive and negative cycles of an AC power source by base-grounded and emitter-grounded transistors. CONSTITUTION:When a bidirectional switch element 2 is turned OFF, a current flows through a diode 14, an emitter-grounded transistor 15 and a resistor 16 in the negative half cycle, a current flows through the resistor 16, a base-grounded transistor 17 and a diode 18 in the positive half cycle to turn ON the transistors 15, 17, and a Hi output is input to the input I2 of a microcomputer 3. On the other hand, when the element 2 is turned ON, a voltage is not almost presented at both ends of the element 2, and the both transistors 15, 17 are turned OFF. Accordingly, the first I2 of the microcomputer 3 is always input with L0. When the microcomputer 3 turns OFF the element 2, if the L0 is input for approx. 1/4 cycle or longer, the transistor 10 is turned ON to melt a temperature fuse 12.

IPC: H01L21/28
Filed: 1990-06-12
Abstract: PURPOSE:To constrain a connecting resistance between a wiring and a diffusion layer in a lower position by a method wherein a first conductive layer surface exposing to an opening part provided in an insulating film is purified without giving etching damages. CONSTITUTION:After an insulating film is formed with an opening part, a first conductive layer 2 surface of an opening part 4 is purified without giving etching damages to remove an etching damage layer and a silicon natural oxidized film 8. Then, an alloy film containing silicon in an opening pat is formed and heat-treated, whereby separating silicon is formed. A second conductive layer 5 is coated thereon, and the second conductive layer and first conductive layer are electrically connected. Accordingly, since etching damages on the surface of the first conductive layer and a silicon spontaneously oxidized film are purified and removed, the separating silicon is certainly separated out inside the opening part and difference in level of a wiring on the opening part is made small. In addition, since growth of the separating silicon is uniformly made, a value of a connecting resistance between the second conductive layer and first conductive layer on the insulating film is lowered.

Abstract: PURPOSE: To widen the dynamic range for sensing voltage by comparing the first input current with the second input current, and at the same time, generating a signal only when the first input current exceeds the second input current by a specified amount. CONSTITUTION: An L1 processing circuit 106, a C1 processing circuit 110 and a CO processing circuit 114 match the voltage of an L1 line 138, a C1 line 146 and a CO line 150 to respective reference voltage, so that an electric potential drop is caused at both ends of registers RL1, RC1 and RC0. Thus, currents IL1, IC1 and IC0 are generated, and added at addition nodes 202, 206 and 210. The scum current of an L2/L1 addition node generates IL1DIF differential current equal to (IL2-IL1) at the L1 processing circuit 106, and the differential current flows toward the addition node 202. In a similar manner, the C1 processing circuit 110 generates ICIDF differential current equal to (IL2-IC1), and the CO processing circuit 114 generates ICODF differential current equal to (IL2-IC0). The processing circuits 106, 110 and 114 mirror-process the obtained differential current for rectification.  The rectified differential currents are supplied to comparators 118, 120, 122, 124 and 126, respectively, and then coupled with reference currents Iref1 -Iref5 .
