Title: Manufacture of semiconductor device
Inventor: KONO MICHIHISA
IPC: H01L21/338
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To enable fine step etching with high precision, by selectively etching an AlGaAs layer exposed to a recessed part by a mixed gas plasma containing a chlorine gas and a fluorine-based gas, then cleaning the surface with water, and measuring the pinch-off voltage between two points on the recessed part. SOLUTION: An undoped high-purity GaAs buffer layer 2, an Si-doped n-type AlGaAs electron supply layer 3, and an n-type GaAs contact layer 4 are sequentially grown by epitaxial crystal growth on a semi-insulating GaAs substrate 1. Then, a recessed part aperture pattern is formed, and reactive ion etching of the n-type GaAs layer 4 in the recess aperture is performed using a mixed gas plasma containing BCl3 and SF6 which have a large selective ratio with respect to GaAs and AlGaAs. Next, by performing cleaning with water, a crystal transformation layer on the side of the AlGaAs surface is removed. Then, an electrode 8 of tartaric acid solution is caused to contact two points of the recessed part, and pinch-off voltage is measured by C-V measurement.

Title: Automatic paper-thickness detecting mechanism
Inventor: MATSUOKA EIJI
IPC: B41J13/00
Filed: 1987-03-24
Abstract: PURPOSE:To enable an appropriate gap to be automatically set, by designating only a retracting operation of a head by an initializing means when a power source is turned ON and at the time of resetting, and designating detection of the surface of a paper and stand-by of the head by a gap forming means at the time of starting printing. CONSTITUTION:When a power-ON or reset-ON operation is applied to a CPU 13, a designation of moving a head to a retracted position separate from the surface of a paper is issued according to a signal from a driving processor 15. Setting of a distance for the retracted position is made by setting the driving of a stepping motor 9 to, for example, 180 steps at maximum, whereby the head is stopped at a distance corresponding to the set value. At that position, the motor 9 is stepped-out, and the position is detected by a conventionally known step-out detecting means 19. The head waites for a printing command at that position. When the printing command is issued from the CPU 13, a gap forming means 18 is operated through the processor 15, thereby bringing the head into contact with the surface of the paper, and when the step-out state is detected by the detecting means 19, the head is thereafter retracted by a predetermined gap, and is thereby positioned at a printing position.

Filed: 1988-03-25
Abstract: PURPOSE:To obtain the minimum value of a function in a short time by deciding a temperature so that a time, when the function is changed from an initial condition up to a condition to give the minimum value, can be made minimum. CONSTITUTION:At the time of obtaining the minimum value of a function E to have many extreme values, the maximization of exp(-E/T) is considered instead of the function E. A parameter T is called temperature, it is introduced in order to generate a random noise and to permit a probability-like management, and when an attainment to the minimum value of the E is executed, the T is brought to O, and it needs to be remain at the minimum value without an error. Then, the temperature T is decided so that the time from the initial condition up to the condition to give the minimum value which is a final goal can be made minimum. Thus, the minimum value can be surely and speedily obtained.

Title: Fm receiver
Inventor: HORIIKE YOSHIO
IPC: H04B1/10
Filed: 1981-05-08
Abstract: PURPOSE:To eliminate noises, by performing the changeover between a radio reception mode and a TV reception mode when a varicap voltage exceeds the prescribed value. CONSTITUTION:The varicap voltage of a tuning varicap D1 is 6V in 90MHz and 8V in 95.75MHz, respectively, No current flows to a Zener diode D2 in the varicap voltage of 6V or so when the Zener voltage of the diode D2 is about 7V.  The varicap voltage becomes 8V in the tuning frequency of 95.75MHz, and the  current flows to the diode D2. Thus an pulselike noise eliminating circuit 46 is  earthed, and as a result, the signals supplied to the circuit 46 are delivered as  they are. Accordingly, the malfunction of the circuit 46 caused by the effect of  the subcarrier wave used for the multiple voice broadcast of TV is prevented to  produce no noise.

Title: Optical temperature measuring instrument
Inventor: HISHIKARI ISAO
IPC: G01K11/12
Filed: 1987-03-25
Abstract: PURPOSE:To perform stable temperature measurement with high sensitivity by using an interference film filter as a temperature sensing part and an image sensor for a photodetection part and measuring temperature from variation in the quantity of photodetection. CONSTITUTION:Light from a light source 1 is projected by an optical fiber 21 on the interference film filter 3 as the temperature sending part which varies in transmissivity or reflection factor with temperature and light from an optical fiber 22 is diffracted spectrally by a spectral means 4 such as a diffraction grating and photodetected by the image sensor 5 such as a CCD. The interference film filter 3 shifts in transmission wavelength characteristics to the long- wavelength side as the temperature rises, so the peak value wavelength and temperature are found previously. Further, picture elements of the sensor 5 and wavelength are made to correspond to each other and then the temperature is measured stably with high accuracy from the picture element position of the peak value or bottom value among respective picture element outputs without being affected by variation in the light quantity and the optical path.
