Title: Doping method in gallium-aluminum-arsenic layer
Inventor: TANAKA TOKUJI
IPC: H01L29/812
Filed: 1984-10-05
Abstract: PURPOSE:To enable controlling in good reproducibility, uniformly and in a required electron concentration by setting the concentration of a doping source SiH4 supplied in a reaction container at the time of forming an N type GaAlAs layer near the maximum electron concentration of the formed N type GaAlAs layer. CONSTITUTION:At the time of forming an N type GaAlAs layer using a doping source SiH4 in the thermal decomposition vapor phase growth of a III group element organic metal compound, e.g., (CH3)8Ga, (CH3)3Al and a V group element hydrogen compound, e.g., AsH3, SiH4 of the concentration set to near the maximum electron concentration of the GaAlAs layer against the concentration of SiH4 is supplied in a reaction container for doping. This reduces the dependability of the electron concentration of the GaAlAs layer upon the concentration of SiH4 near the above-mentioned maximum value and the electron concentration of the GaAlAs layer is made nearly constant whereby the dispersion of the electron concentration of the GaAlAs layer is greatly improved. Consequently, a high electron concentration GaAlAs layer excellent in uniformity and reproducibility can be formed.

Inventor: OHIRA YOSHIHIRO
IPC: G01B15/02
Filed: 1990-08-08
Abstract: PURPOSE:To obtain the method and the apparatus for measuring the thickness of the material attached t the inside of a pipe which can measure the thickness of the material attached to the inside of the pipe to be measured without using the similar reference pipe as the pipe to be measured by emitting radiation toward the pipe to be measured, and detecting the intensity of the radiation which is transmitted through the pipe to be measured and the material attached to the inside of the pipe. CONSTITUTION:Ultrasonic waves are transmitted from ultrasonic-wave transceivers 4 and 5, and the reflected waves are received. The thickness-value signal of a pipe to be measured 1 is outputted and stored in a memory 16. The positions of the ultrasonic-wave transceivers 4 and 5 are operated. A jig 7 is rotated by an angle theta in the clockwise direction. A radiation source 2 and a detector 3 are arranged on the central line of the pipe to be measured 1. Thereafter, radiation is emitted from the radiation source 2. The intensity of the radiation which is transmitted through the pipe to be measured 1 and a material to be attached to the inside of the pipe 1a on the central line A1 - A2 is detected with the detector 3. When the measurement of the thickness of the material attached to the inside of the pipe 1a at one place is finished, the measuring person turns the jig 7 at the specified angle. The thickness of the material attached to the inside of the pipe 1a are sequentially measured along the entire surface of the pipe to be measured 1.

Title: Method and device for recording
Inventor: OCHI HIROSHI
IPC: G03G15/08
Filed: 1983-11-08
Abstract: PURPOSE:To eliminate the need for uniform electrostatic charging by exposing a photosensitive body, and performing development simultaneously with or right after the exposure. CONSTITUTION:The photosensitive body 20 is in a drum shape and incorporates a light emitting diode array 6 and as self-focusing lens 7. Charged toner 4' sticks on the surface of a sleeve 5 and is supplied to near the surface of the photosensitive body 20, but the charged toner layer 4 on the sleeve 5 does not contact the surface of the photosensitive body 20. An exposure system for photosensitive body exposure is arranged in the photosensitive body 20 and an image of the light emitting diode array 6 is formed on a photoconductor layer 1 through the self-focusing lens 7. While the drum-shaped photosensitive body 20 is rotated as shown by an arrow 15, a pulse voltage P1 having such a polarity that the charged toner 4' is attracted to the surface of the photosensitive body 20 is applied to the sleeve 5 which serves as a counter electrode synchronously with light image irradiation. Thus, the need for uniform charging is eliminated and a corona charger which requires a high voltage need not be used.

Title: Ultrasonic decision device
Inventor: SATOU HARUJI
IPC: G01N29/07
Filed: 1983-11-07
Abstract: PURPOSE:To stabilize data by controlling the level of the transmission output of an ultrasonic decision device which detects whether there is decay in a wood column or nondesctructively according to the output of a reception part, and measuring transmission time when the amplitude of the reception output exceeds a fixed value. CONSTITUTION:The signal e0 that a pulse transmitter 18 outputs by receiving the output Es of a synchronizing part 1 varies in amplitude on every transmitting operation with the output of eT of a control signal receiver 17 which varies stepwise. The reception output from the intermediate state of an amplifier 14 is detected by a detector 20 and compared as a signal ED with a comparative voltage EHB by the 2nd comparator B21, which outputs a signal ER when the signal ED exceeds the voltage EHB. The output of the control signal generator 17 is cleared to ''0'' at the falling time C of the signal ER and the output value of a counter 5 is held in a latch 22. Consequently, the transmission time is measured when the amplitude of the reception output exceeds the fixed value, so stable data is obtained.
