Title: Formation of ohmic electrode
Inventor: YAMADA YOSHINORI
IPC: H01L21/28
Filed: 1980-07-14
Abstract: PURPOSE:To increase the reliability of an ohmic electrode for an FET or the like by forming a high melting point metal layer of Pt, Ni or the like at a predetermined thickness ratio on an Au-Ge alloy film covered on a GaAs substrate, and alloying it with plasma Si3N4 film by covering, thereby smoothing the electrode. CONSTITUTION:An Au-Ge alloy film and, for example, an Ni film of the thickness of 1/5-1/20 of the alloy film are formed as source and drain electrodes 3, 4 on a semi-insulating substrate 1 epitaxially grown with N type operation layer 2. After an Si3N4 film 5 is covered at low temperature (lower than 350 deg.C) by a plasma CVD method, it is alloyed in an ohmic contact. Then, the film 5 is opened, a pad electrode 6 made of Cr, Au is formed, and source and drain electrodes are thus completed. Since the ball-up of the alloy can be prevented in this manner, the surfaces of the electrodes can be smoothed, and the ohmic electrodes which are not deteriorated at the contacting resistance at high temperature can be provided.

Abstract: PURPOSE:To shorten a timer required for check or the output of an accounting report by dividing one report into two, and print-outputting the one of a receipt and the other on a journal almost simultaneously. CONSTITUTION:An electronic cash register is equipped with a CPU (central processing unit) 1, a bus line 2, a ROM 3, a RAM 4, a time-piece circuit 5, a mode switch 6, an I/O port 7, a keyboard 8, a keyboard circuit 9, a display 10, a display control circuit 11, a printer 14, a printer driving circuit 15, a drawer 16, a drawer opening device 17, and an I/O port 18. Here, one report is divided into two, and the one is printed on the receipt 12 and the other on the journal 13 simultaneously, respectively. Therefore, since one report is outputted simultaneously by dividing into the receipt 12 and the journal 13, output time can be shortened nearly to the half. Thereby, it is possible to reduce the time required for the check and the output of the accounting report.

IPC: H02N13/00
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To facilitate the method of setting an opposite polarity voltage in the case where a sample is separated from an electrostatic adsorption device, to simplify a control of the opposite polarity voltage and moreover, to cope also with a space-charge polarization (space- charge polarization to take a time for eliminating an electrification), which is generated in the case where an insulating film is formed on the rear (electrostatic adsorption side) of a semiconductor wafer of the sample, and to enable the separation of the sample from the device easily and smoothly even though the kind of the sample and the adsorption time of the sample on a dielectric material are changed. SOLUTION: A sample 1 is adsorbed on a dielectric material 2 and after a desired process ends, a switch 4 is changed over into a position (a) and the supply of a DC voltage 5 for electrostatic adsorption is stopped. A conductive pin 10 is opened and an air cylinder 14 is actuated to make the sample 1 separate from a push-up pin 12 by the elastic force of a spring 13. In the case where the sample 1 cannot be made to separate, this impossibility is discriminated by a position sensor 16 and the switch 4 is changed over into a position (c) to apply a reverse voltage to the sample 1. The strength of this reverse voltage is controlled by a controller 7 so that the strength approaches 0 along with an elapse of a time. An electrostatic force stored in the rear of the sample 1 is offset by a certain voltage and the separation of the sample 1 from the pin 12 becomes possible.

IPC: H01S3/03
Filed: 1979-07-27
Abstract: PURPOSE:To obtain a gas laser tube which is inexpensive, highly reliable, and suitable for mass production, by adjusting the loss of oscillated light by externally moving the insertion angle of a glass plate, and by converging the dispersion of the output values. CONSTITUTION:An outside housing 1 and a mirror 2 are connected by a metal support 4, flanges 4'-4''' are provided on the support 4, and a glass plate 5 is arranged in the support 4. While, the outside housing 1 and the mirror 3 are connected by a thin glass pipe 6, and an anode pin 7 is attached in the middle of the thin pipe 6. A cathode pin 8 which is located at the end of the outside housing 1 is connected to a cathode 9. A specified voltage is applied across the anode pin 7 and the cathode pin 8, and the laser tube is discharged, thereby a laser light 10 is emitted. In this case, the output value of the laser light 10 varies depending on the insertion angle of the glass plate 5 and the dispersion in the values of other parts. If the insertion angle of the plate 5 is adjusted by moving the flanges 4' and 4''' with pincers, the desired value can be obtained. The misalignment caused in the mirrors 2 and 3 is adjusted by the flange 4' and 4'' and the pincers. Thus, the mass production can be easily carried out by making it possible to adjust the insertion angle of the plate 5 from the outside.

Abstract: PURPOSE:To give tension to plural wires uniformly with one device at the same time, and make the space required smaller, by rolling these wires drawn out of a wire bobbin on plural reels parallelly installed in one fulcrum shaft, and setting braking force to the fulcrum shaft being rotated by friction of these wires. CONSTITUTION:Winding wires 8 are rolled on plural reels 17 parallelly installed in one fulcrum shaft 16, and braking force is given to the fulcrum shaft 16 to be rotated by friction of these wires 8 via these reels 17 at a tension source, then the required tension is given to respective wires 8 to be rolled on a coil winding part 13. Therefore, tension is uniformly giveable to these plural wires 8 with one of plural wire tension devices 15 at the same time, so that a floor space for the tension device 15 can be made smaller. In addition, the number of parts items is reducible and each tension device is simplifiable in structure and, what is more, tension adjustments can be done with the tension source of one fulcrum shaft 16 in common, thus adjusting operation is simplified and simultaneously variations in the tension can be brought to nothing.

Title: Resonance-type flyback converter circuit and controlling method therefor
Inventor: YUGUCHI TASUKU
IPC: H02M3/28
Filed: 1993-04-22
Abstract: PURPOSE:To realize a large control range in a converter circuit, by connecting a resonance capacitor in parallel with a switching element, and constituting a resonance circuit with inductance on a primary side of a transformer. CONSTITUTION:On a primary side of a transformer (T) a parallel circuit of a switching element and a resonance capacitor is connected in series to inductance (LP) between a power supply (VCC) and a ground (GND). Then, at a transient time from on to off or from off to on, a serial circuit made up of the inductance (LP) and a capacitor (Cr) is formed so that the transient characteristic is determined while the switching element has relatively high impedance. In this case, when resonance frequency at the rated load is set higher than an audio frequency band, an artificial load at light load becomes unnecessary. When a duty factor of switching pulses at heavy load is designed to be about 50%, the EMI characteristics are improved.
