Title: Semiconductor circuit device
Inventor: KATO HAJIME
IPC: H01L23/373
Filed: 1990-09-07
Abstract: PURPOSE:To inhibit the generation of a thermal stress and the temperature rise of a semiconductor element by a method wherein in the case the element is mounted on an insulating circuit board via a heat sink, a composite material consisting of copper and glass is used as the material for the heat sink. CONSTITUTION:An insulating circuit board 5 is bonded on a heat sink 7 made of Al through a silicon resin adhesion layer 6 and a heat sink 9 made of a molybdenum and a power transistor chip 1 are soldered in order on the substrate 5. In this constitution, a composite material consisting of copper and glass is used as the material for the sink 9. This composite material is obtained by a method wherein copper powder and glass are kneaded so that the content of copper becomes 90wt.% to form into a pasty form, the pasty material is flowed in a metal mold and the powder and the glass are integrally sintered at 800 deg.C. Thereby, heat, which is generated when the chip 1 is actuated, is effectively dissipated. Moreover, a difference between the linear expansion coefficients of the sink 9 and the substrate 5 is small and no crack is generated in solder layers 2 and 4.

Title: Rotating position detecting apparatus for internal combustion engine
Inventor: ITO MASAYUKI
IPC: G01D5/244
Filed: 1991-09-18
Abstract: PURPOSE:To detect a reference position correctly in a simple constitution without being influenced by the shape accuracy of a rotor or the change of the cycle of an angular signal by the rotating speed. CONSTITUTION:Up-down counters 17, 18 count up/down clock pulses in accordance with a string of pulses from a rotation sensor 3, and detect the data of the irregular interval corresponding to a reference position from the pulse string. An angular signal is frequency-demultiplied by a frequency demultiplier 6. The first and second up-down counters 17, 18 are stopped to count up/down the clock pulses for two cycles of the angular signal. At the same time, the first and second up-down counters 17, 18 are let to count up and down alternatively for every one cycle of the angular signal. Accordingly, a reference position is detected from a detecting output of either of the up-down counters 17, 18.

Title: Chopper type regulator circuit and chopper type regulator ic
Inventor: SUZUKI TOMOHIRO
IPC: H02M3/155
Filed: 1995-09-18
Abstract: PURPOSE: To regulate the loss of a driver by providing a base current output terminal for outputting a base current flowing at an output transistor and connecting a base current output terminal to a load. CONSTITUTION: When the output of a PWM comparator 4 becomes 'L:, an N-P-N type transistor(NP) 65 is turned OFF, and a current flows at the NP 64. NPs 63 and 64 are a current mirror configuration. The current flowing at the NP 63 is the emitter area ratio of the NP 63 to NP 64, and the same current also flows at a P-N-P type transistor(PN) 61. PNs 61 and 62 are current mirror configuration. The current flowing at the PN 62 is the emitter area ratio of the PN 61 to PN 62. In this case, the area of the PN 62 to the emitter area of the PN 61 is sufficiently increased thereby to reduce the loss of a constant-current circuit 19. That is, when an output transistor(Tr) 18 is turned ON, the base current of the Tr 18 flows to the base current output terminal IB via the PN 62 and flows to a load 12.

Abstract: PROBLEM TO BE SOLVED: To simply and correctly measure a high frequency current flowing in a coaxial cable together with waveform data without switching transmission routes, etc., by arranging a high frequency current transformer in the outer circumference of the coaxial cable and detecting a leakage current. SOLUTION: In order to measure, for instance, a high frequency current at a plasma etching apparatus, a high frequency current transformer 6 of a clamp type or the like is arranged in the outer circumference of a coaxial cable 5 connecting a matching box 2 with an apparatus body 3. The coaxial cable of a structure, e.g. using a metallic mesh as an outside conductor has some external radiation.
