Patent JP-H01179452-A (JP)
Title: Heterojunction semiconductor device and manufacture thereof
Inventor: MATSUMOTO HIROSHI
IPC: H01L29/73
Filed: 1988-01-06
Abstract: PURPOSE:To realize a high emitter efficiency, a high carrier speed and a high collector breakdown strength by a method wherein the title device is constituted into a structure, wherein an impurity distribution in a base is set into a high concentration in the vicinity of an interface on the side of an emitter and is decreased steeply toward the side of a collector. CONSTITUTION:A heterojunction semiconductor device is constituted into a structure, wherein an impurity distribution in a base 10 is reduced steeply from the side of a high concentration emitter (GaP epitaxial layer) 2 toward the side of a collector region 5, and a high emitter injection efficiency, a low base resistance, a high-speed carrier traveling and a high collector breakdown strength are satisfied simultaneously. The former both are contributed by a fact that the concentration of the base 10 is high at the ends of the emitter and the latter both are contributed by a fact that the concentration of the base is low at the ends of the collector. Moreover, as the side of a sapphire substrate 1, which is an insulator, is the emitter, an emitter-substrate capacity is sufficiently small and the surface side is the collector and comes into contact directly with an electrode wiring layer at the upper part of the collector, a collector-substrate capacity can be removed. Moreover, as the emitter is an epitaxial layer on the insulator substrate, carriers are completely depleted in the substrate, an emitter- substrate capacity is very small and the high-speed efficiency of a heterobipolar transistor can be fulfilled sufficiently in an integrated circuit.

Title: Vibration type transducer
Inventor: YOSHIDA TAKASHI
IPC: G01L9/00
Filed: 1992-01-09
Abstract: PURPOSE:To measure a strain with high accuracy with a simple constitution by selecting a drain resistance, capacitance between a drain and substrate, and oscillating angular velocity so that their product can become extremely larger than '1'. CONSTITUTION:Since a negative potential is applied across a mobile electrode 30 from a DC power source E2, electrons are forcibly pushed toward the inside of a silicon substrate 24 from the lower surface of the vibrator 30 and, on the contrary, holes (p-type) are attracted toward the surface of the substrate 24. Because of the holes, a channel CNN composed of a p-type conductive layer is formed on the surface of the substrate 24 and an electric current id flows between a source S and drain D. The voltage the drain D generated by the current id is shifted in phase by a drain resistance RD and the capacitance CD formed between the drain and substrate 24 and, due to the potential change, the electrostatic attracting force between the electrode 30 and drain D changes, resulting in a change in the interval X between the electrode 30 and drain D. The oscillation caused by the potential change continues when the resistance RD, capacitance CD, and oscillating angular velocity omega are selected so that their product can become extremely larger than '1'. When a pressure PM is applied to the substrate 24, a strain is applied to the electrode 30 and its characteristic frequency varies. The pressure PM is detected by fetching the variation.

Abstract: PURPOSE:To reduce the smoke density and to increase the torque by controlling the supercharge pressure in a supercharger through the smoke density such that the supercharge pressure is increased as the increase of the smoke density to increase the suction air of an engine. CONSTITUTION:When the engine rotation is lower than 2,000rpm, the increase of the smoke density is detected by a smoke detector 26 to produce the amplified signal from an adder 35 to vary from L1 to L2 while the output from a comparator 32 will vary from P1 of B to P2 of C. Then it will function to open wide a solenoid valve 34 to close a west gate valve 24. When the engine r.p.m. exceeds over 2,000rpm, the output from an amplifier 28 is corrected by the output from D.C. current generator 33 for receiving a signal from an engine r.p.m. detector 31 as the increase of the smoke density. The opening of said solenoid valve 34 is lower than when r.p.m. is lower than 2,000rpm.

Title: Method for controlling sheet width in rolling mill
Inventor: SAKURADA KINYA
IPC: B21B37/00
Filed: 1988-01-08
Abstract: PURPOSE:To improve the sheet width accuracy and yield of a strip by setting a minimum value of variations in sheet width as a control target value and to control a tension between stands so that a measured sheet width value agrees with the target value. CONSTITUTION:A sheet width gage 3 is installed between stands of a rear stage rolling mill 2 of a hot continuous rolling mill and a sheet width minimum value detector 4 and a tension arithmetic unit 5 are also installed immediately after the gage 3. When the top end of a strip 1 reaches the gage 3, a measured sheet width value is inputted to the detector 4 and the detector 4 sets a sheet width minimum value at a moment where an output changing percentage changes from a minus value to a plus value as a target value of sheet width control and inputs the minimum value into the arithmetic unit 5. Then, the unit 5 finds a deviation between the measured sheet width value and the target value and inputs the deviation into a tension controller 6 to perform tension control. The sheet width accuracy and yield are improved because the sheet width control is performed by setting the target value restraining sheet width variation.

Abstract: PROBLEM TO BE SOLVED: To prevent magnetic powder such as friction powder and chip powder from being attracted to a work coil, to prevent the work coil from being damaged due to electric discharge and to greatly extend a forming roll life and a work coil life by specifying an oil quantity stuck on the surface of a hoop to be formed to a tubular body and making friction resistance with the forming roll proper. SOLUTION: When gradually tube-forming a hoop 1 from a U shape to an 0 shape by a forming roll 2, because rotation speeds are different at a part (a) and a part (b) or part (c) where the forming roll 2 of the smallest radius (r1) is brought in contact with the hoop 1 of the largest radius (r2), chip friction powder and chip powder are generated on the surface of the hoop 1 and the forming roll is worn. Also, when the magnetic powder such as the friction powder and the chip powder on the surface of the hoop 1 passes through a work coil, is attracted to the work coil by a high frequency current and when is accumulated to discharge, damages the work coil.  When the magnetic powder has an oil sticking quantity on the surface of the hoop 1 by 0.1-1.5 g/m<2> , the friction resistance between the forming roll 2 and the hoop 1 becomes proper, the attraction of the friction powder and the chip powder to the hoop 1 is prevented.
