IPC: H01S5/343
Filed: 1983-07-26
Abstract: PURPOSE:To obtain the FET which can be operated stably by a method wherein an electron block layer is superposed on a semiconductor substrate, the first semiconductor layer of N type having the thickness of electron wavelength or below and the second layer of small electron affinity and of the thickness with which an electron can be passed through are alternately laminated, and a working layer having large affinity is superposed thereon. CONSTITUTION:A high purity As electron block layer 2 consisting of Al0.5 and Ga0.5 is formed on a semiinsulating GaAs 1, an N type Si-added GaAs 9 of approximately 23Angstrom  in thickness and a high purity AlAs 10 of approximately 15Angstrom  in thickness are alternately laminated thereon, then a high density GaAs 4 is superposed, and an Al gate electrode 6 and Ai-Ge/Au electrodes 7 and 8 are attached. The electron generated from an N-layer 9 is distributed all over the laminated body by the quantization level Eq generated from the laminated body of the layers 9 and 10, and a deep electron trap relating to impurities is not formed. As the level Eq is higher than the conduction band Ec of the layer 4, the electron of the level Eq is partially drops to the layer 4, and secondary electron gas 5 is formed on an interface. However, as there is no deep trap level, no fluctuation in the secondary electron is generated by the irradiation of light and hot electron, and no difference is made in density at the room temperature and the low temperature, thereby enabling to obtain a stabilized FET operation.

Abstract: PURPOSE:To obtain a differential amplifier which supplies both differential outputs to a final-stage amplification part and is driven by a low-voltage power source by compensating mutual input voltage ranges by suing the 1st differential amplification part which has a P type MOSFET as an input transistor (TR) and the 2nd differential amplification part which has an N type MOSFET as an input TR, and composing one output of those differential outputs while making the DC bias point of one output coincident with the output bias point potential of the other output by a level shifting means. CONSTITUTION:The output terminal 20 of the level shifter 14 is connected to the output terminal 19 of a differential amplifier 200 to send a gate signal to the MOSFET 9 of the final-stage amplification part. Here, the quantity of the voltage shifting of the level sifter 14 is set properly and the voltage level at its output terminal 20 is equalized to the voltage level at the output terminal 19 of the differential amplifier 200. This circuit uses N type MOSFETs 3 and 5 and P type MOSFETs 5 and 6 as respective input MOSFETs of the two differential amplification parts 100 and 200, so even when a low voltage source is used, an input voltage level to be used has a wide range from a low supply voltage VSS to a high supply voltage VDD.

Title: Gas chromatograph apparatus and operation thereof
Inventor: MARUSURU JI U GOREI
IPC: G01N30/64
Filed: 1989-05-31
Abstract: PURPOSE: To enhance the economy, reliability and efficiency by coupling a detector with a switching assembly for filling a detector chamber alternately and selectively with carrier gas and column gas flow. CONSTITUTION: A gas source 34 generates a controlled faint gas flow of He in a cell chamber 30 through a coupling 36. When a hot wire 32 is heated through current control from a control circuit 33, He gas in the chamber 30 is discharged into a detection chamber 22 which is thereby filled with pure He. Gas in the chamber 22 is discharged to the main gas flow of chromatograph and substituted. Since the wall of switching cell 28 has sufficiently low temperature, heated gas in the chamber 30 is quenched when the wire 32 is inactivated and the pure He in the chamber 22 is sucked. Consequently, a gas flow can be sucked from a column 16 into the chamber 22 for the purpose of measurement and controlled pumping action can be ensured without requiring any movable component.

Filed: 1989-05-30
Abstract: PURPOSE:To demodulate data without generating a data error by providing a comparing value setting circuit to prepare a comparing voltage value to be changed corresponding the value of a gain control voltage, which controls the gain of a variable gain amplifier, in a fixe anplitude circuit. CONSTITUTION:In a fixed amplitude circuit 4, a comparing value setting circuit 43 is provided and the comparing voltage value is prepared to be changed corresponding the value of the gain control voltage which controls the gain of a variable gain amplifier 41. Then, this value is used for comparing a fixed amplitude signal in a comparator circuit 5. When the amplitude level of an input signal magnetic head reproducing signal to the variable gain amplifier 41 is small, this gain control voltage is high and when the level is large, the voltage is low. Accordingly, the comparing voltage value is prepared by utilizing this gain control voltage. The comparing voltage value to be used in the comparator circuit 5 is defined as the voltage value to be change in correspondence to the value of the gain control voltage. Thus, even when rounding is generated in the waveform of the fixed amplitude signal, the data can be correctly demodulated without extendig the pulse width of an amplifier sense signal.

Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To provide an incandescent lamp lighting circuit capable of substantially reducing high frequency components, controlling output voltage value, maintaining a specific light output and extending service life of an incandescent lamp by lightening a burden applied on an incandescent lamp load. SOLUTION: A power supply switch SW1 is switched on to apply full-wave rectification to a current supplied from a commercial power supply by a diode bridge D2, and the current is sent to a switch element Q1 after being charged in a capacitor C2. Since the switching element Q1 is switching at a high speed and an input current lin proportional to an input voltage Vin passes through it at a steady state, high frequency components can be reduced substantially. Energy is stored in and discharged from an inductance L1 and a capacitor C3, by switching on and off of the switching element Q1. A fixed voltage is supplied to an incandescent lamp load by this operation. In addition, a voltage between both ends of the incandescent lamp load R2 is fed back, in order to fix a load voltage and maintain a specific light output.
