Abstract: PURPOSE:To improve the performance of a compound semiconductor device without contamination on the surface wherein epitaxial growth is performed, by forming an oxide film in the clean super-high vacuum atmosphere before the compound semiconductor surface is polluted by such substances as oil and dust in the air. CONSTITUTION:n-GaAs film 2 is laminated on n<+>-GaAs base 1 by the molecular beam epitaxy (MBE) method and then oxide film 3 is formed by introducing oxygen or water vapour in the super-high vacuum chamber onto base 1 having film 2 which is heated up to 200 deg.C-300 deg.C. Next, base 1 is taken out from the super-high vacuum chamber and then tungsten is deposited by the electron beam evaporation method. W base 4 is formed on oxide film 3 by photoetching and then base 1 is reintroduced into the molecular beam epitaxy device and heated up to 550 deg.C or more. As a result, clean gallium arsenide surface can be provided since the surface contamination substance formed by exposing base 1 to the air is removed from the base surface together with oxide film 3. Furthermore, ohmic electrode 6 is formed by laminating n<+>-GaAs film 5 and then by depositing Au-Ge-Ni alloy on both sides of base 1 by using the resistance heating method.

Abstract: PURPOSE:To obtain a PLL output signal with high accuracy by providing a frequency division circuit, a circuit comparing the phase of an input signal whose phase is inverted at a prescribed period and that of an output signal of the frequency division circuit and an oscillation circuit whose oscillating frequency is controlled by the output signal and supplying the output signal to the frequency division circuit. CONSTITUTION:Only one period is extracted from an output signal of a waveform division shaping circuit 3 by a burst wave extraction circuit 5. The extraction is applied based on the front or rear edge of a horizontal synchronizing signal based on a timewise reference. Moreover, a signal obtained by frequency-dividing a horizontal synchronizing signal at a 1/2 frequency division circuit 7 is fed to the circuit 5 to switch the said extracted position for each horizontal synchronizing period. The phase of the output signal of the circuit 5 is compared with the phase of the output signal of the frequency division circuit 10 by a phase comparator circuit 6 and the frequency of a 4fsc oscillator 8 is controlled by the result of comparision. The oscillated frequency is set to 910H, that is, 4fsc. The circuit 10 is switched for each of one horizontal synchronizing period for 1/909 frequency division and for 1/911 frequency division. Then the output signal of the circuit 10 is a signal rising for each one horizontal syncrhonizing period based on the output.

Title: Analog switch
Inventor: TAKAGI NOBUYOSHI
IPC: H03K17/16
Filed: 1983-09-30
Abstract: PURPOSE:To eliminate the switching noises produced by the stored electric charge by using an element which stores the electric charge to obtain an analog switch and connecting a discharging circuit to the analog switch. CONSTITUTION:When the control signals are supplied to analog switches 31- 3N, MOSFETa and MOSFETb conduct with an MOSFETc turned off respectively. Therefore the signal charge flows through the analog switch, and a picture element signal is produced at an output terminal 4. Meanwhile the electric charge is induced at the electrostatic capacity between the gate and the source/ drain of the FETa and FETb and then stored. However this stored charge is discharged via an FETc which is turned on with the electric charge of a high level applied via an inverter (d) when the analog switch is turned off. Therefore the mixture can be eliminated in the next scan for a noise component which will be superposed on the picture element signal to be extracted.

Title: Measurement for coherence biometry by dynamic coherent focalpoint and method for photographing fault
Inventor: ADORUFU FURIIDORITSUHI FUERUHI
IPC: G01B9/02
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To achieve high and good resolution over the entire depth of an object when dynamic coherent focus is used by performing the displacement of focus and the adjustment of optical path length between measuring light beam and reference light beam through displacement of a single optical element. SOLUTION: Lateral resolution is enhanced when the position of a light returning part is measured using the measuring light beam of a short coherence interferometer comprising a Kosters double prism. Path length of a measuring arm and a reference arm having identical optical length is adjusted and the position of a light returning part in an object along measuring section is determined from the modified length of a measuring light beam 10 and/or a reference light beam 9 required for adjustment of path length. In this regard, the measuring light beam 10 is focused in or on the object and a measuring focus is shifted along a measuring section for the purpose of scanning while keeping coherent state with respect to the reference light.  Shifting of measuring focus and adjustment of the path required for ensuring coherence with respect to a reference light 2' are thereby performed by shifting a single optical element.
