Abstract: PURPOSE:To maintain surely an electric contact with a base, and prevent the recombination of minority carrier in a base region, by keeping electric continuity to a first region composed of first conductivity type formed in the vicinity of an electrode film and a semiconductor surface by the dielectric breakdown of an insulating film. CONSTITUTION:After the impurity diffusion regions of an emitter, a base and a collector are formed, an insulating film is formed so as to cover at least a base region surface, and a base electrode 18 is arranged thereon. Contact holes 21, 22 are made to lead out the electrodes of an emitter 17, a base 18, and a collector 19 with aluminum wirings. By applying a voltage between the base and the emitter or the collector, the oxide film formed on the surface of the base region is subjected to dielectric breakdown to obtain an electrical continuity 23 to the base electrode. Thereby, electric contact with the base can be surely obtained in spite of a thin base width, and the recombination of minority carrier in the base region can be restrained.

Title: Oil hydraulic multi-lief clutch
Inventor: KIMURA HIKARI
IPC: F16D48/02
Filed: 1983-05-14
Abstract: PURPOSE:To prevent shock and/or vibration caused by counter-load at the time of violent deceleration of a car by furnishing a relief valve on the way of a by- pass diverging at the midway of the pressure oil supply line, wherein the relief valve shall open to relieve the oil when any violent deceleration is sensed. CONSTITUTION:In the event of rapid deceleration of a car, pressure in a suction pipe on the bottom side of carburettor 47 will rise violently to lead to violent rise of neg. pressure at a diaphragm valve 44, and now another diaphragm valve 58 is put in service while the one 44 is opened. Thereby the oil in a pressure oil supply passage 37 flows out of a by-pass 43 to an oil pan to cause sink of oil pressure in an oil pressure chamber 33, and now the load applied to a pressure plate 27 will reduce to a level approx. equal to the load produced by a clutch spring 29. Therefore friction plates 25, 26 slip with each other to bring about the state that little counter-load is transmitted to the input gear 20 side, i.e. the engine side. Thus shock at the time of deceleration is relieved.

IPC: H03M1/48
Filed: 1992-03-09
Abstract: PURPOSE: To attain coding at an excellent speed in perception by dividing an input signal into spectral bands, selecting and coding N-sets of bands having a highest energy of noise with respect to perception. CONSTITUTION: An analysis filter bank 100 receives an analog input signal through a serial parallel register 105 to generate N-sets of frequency coefficients. Dividers 11-1-11-8 divide a minimum perceptional band signal generated by a perception model block 110 that receives an output of the bank 100 to generate a quotient signal. A selector 120 identifies n-sets of bands having a highest quotient from the quotient signal and provides an output of the result. In the case of analog transmission, an inverse correction circuit 130 generates n-sets of analog signals from this output and modulates them to form base bands having adjacent spectrums, and in the case of digital transmission, a formatter 125 formats the output to each transmission medium. Thus, coding at an excellent speed in perception is attained.

Filed: 1984-04-27
Abstract: PURPOSE:To decrease the number of wires of gate input terminals by arranging NAND gates dispersedly at an input and an output side. CONSTITUTION:The NAND gates 16-19 form RS type FFs 13 and 14, whose outputs -Q1 and -Q2 are connected to a binary input terminal of an MPX29. A table 1 shows which of outputs Q1 and Q2 and output terminals 9, 10, 11, and 12 are at a level L when switches (SW)1, 2, 3, or 4 is pressed. For example, when the SW1 is pressed, the -Q1 and -Q2 are at L and the Q1 and Q2 are at H, which is held. Thus, when one of the SWs is pressed, binary data indicating which SW is pressed appear at the outputs Q1 and Q2, or -Q1 and -Q2. Consequently, one of outputs of gates 20-23 goes down to L corresponding to the pressed SW as shown in the table. For example, when the SW1 is pressed, only a light emitting diode 9 turns on. Then, the outputs of the gates 17 and 19 are applied to the MPX29, one of input terminals 24-27 is connected to an output terminal 28 corresponding to the SW.

CONSTITUTION: The rear end of a buried pipe 1 is pushed while excavating the ground by an excavating head placed in a cutting edge 3, and the cutting edge 3, a leader pipe 2 and the buried pipe 1 are pushed into the ground. The bending of course due to the properties of the ground is confirmed by monitoring a target 8 by a TV camera 9 at that time. When bending is confirmed, hydraulic cylinders 6 placed in the direction of curved propagation are operated, the direction of the cutting edge is corrected, and excavation is continued. Solenoids for solenoid valves corresponding to the hydraulic cylinders 6 are supplied with electricity through power cables by remote control and excited and opened, and pressure oil is fed and the hydraulic cylinders 6 are worked.  Light-emitting diodes corresponding to the operated hydraulic cylinders 6 emit light at that time, and the normal operation of the hydraulic cylinders is displayed. When disconnection is generated in the power cable, the light-emitting diode does not emit light, thus instantaneously discriminating the working of the solenoid valve by viewing the light-emitting diode.
