Title: Growing method for semiconductor thin film
Inventor: SUGAWARA SATOSHI
IPC: H01L21/205
Filed: 1992-04-24
Abstract: PURPOSE:To realize the re-growth of a semiconductor thin film while variations in carrier concentration are controlled by supplying an organometallic compound gas made of a dopant metal when the temperature of a substrate is increased to a re-growth starting temperature. CONSTITUTION:An n-GaAs buffer layer 11, an n-Al0.5Ga0.5As cladding layer 12, a non-doped Al0.13Ga0.87As active layer 13, a p-Al0.5Ga0.5As carrier/barrier layer 14, and a p-Al0.25Ga0.75As guide layer 15 are successively grown over a GaAs substrate 10. Subsequently, three-dimensional diffraction gratings 25 are formed, and the gratings are transferred to the p-Al0.25Ga0.75As guide layer 15. Then, a p-Al0.6Ga0.4As etching-stop layer 16 and an n-GaAs current block layer 17 are successively grown. The second time growth is carried out while diethylzinc is run and also a temperature is increased to 750 deg.C. A third time growth is performed in the same manner as in the second time growth, whereby a drop in carrier concentration of the p-Al0.25Ga0.75As guide layer 15 can be suppressed, and a semiconductor laser with a superior high temperature performance characteristic can be realized.

Title: Detection system for earthing and contact of subscriber's line
Inventor: SATOU CHIKAO
IPC: H04M3/30
Filed: 1978-08-31
Abstract: PURPOSE:To omit the auxiliary power source by connecting the detection means to each subscriber's line and then connecting one side of the line to the power voltage with the other side connected to the divided voltage each. CONSTITUTION:Subscriber's line LA of one side of subscriber's telephone S is connected to power source -48V via detection relay A of detection device DET; while subscriber's line LB of the other side is connected to power source -48V via detection relay B and resistor R. Zener diode ZD is connected to the joint between relay B and resistor R, and the voltage of the joint is set to the constant voltage of, for example, -12V or so. As a result, if the earth fault may occur at line LA or LB, relay A or B operates. In case the short-circut fault occurs at lines LA and LB, both relays A and B have a simultaneous actuation. Thus both the earthing and the contact can be detected with just one unit of the power source.

Filed: 1978-08-30
Abstract: PURPOSE: To make sound the coated film on the stepped part through improvement of the shape of the stepped part of the conductive plated film, by forming the primary layer of the plated film into a multilayer structure consisting of two or more layers, and by specifying the specific resistance of each layer different from other layers.  
     CONSTITUTION: The first conductive film 7 of specific resistance ρ higher than that of Cu, Au, etc., for exampld Fe, Ni, film, etc., is formed on the substrate 1 by the vacuum evaporation method. The second conductive film 8 of low specific resistance like as Cu, Au, etc., is vacuum evaporated on this film 7. Furthermore, by chemical etching method, etc., the films 7, 8, being unnecessary to be plated, are seletively etched and removed using the etching solution which may develop the higher etching velocity for the film 8 than for the film 7. Next, the conductive plated film 3 is formed on these films 7, 8, being shaped into a step. As a result, the film 8 of specific resistance ρ lower than that of the film 7 is plated thicker, and the plated layer at the exposed end face of the film 7 is formed thin. Accordingly, the inclination of end of the film 3 is made gentle, and the insulation film 4 for coating the stepped part of the film 3 is scarcely broken, and the stepped part can be satisfactorily coated with the layer as thin as a quarter or so of thickness of the film 3.

Title: Detecting device of partial discharge
Inventor: YAMASHITA TAKAHIRO
IPC: G01R31/12
Filed: 1988-04-29
Abstract: PURPOSE:To facilitate the detection and analysis of a partial discharge sound, by a method wherein the input of a detection signal from a partial discharge sound detecting sensor to a signal processing circuit is checked by a detection signal of an external noise sensor. CONSTITUTION:When external noise occurs suddenly, both a partial discharge sound detecting sensor 10 and an external noise sensor 13 detect the noise simultaneously. When a detection signal of the sensor 13 inputs to a detection signal checking circuit 12, the signal is rectified by a rectifier circuit 18 and inputted to a peak value holding circuit 19. The circuit 19 raises the level of a control signal for a switch circuit 20 to a prescribed value or above. The circuit 20 is turned off to break a circuit which transmits an output of the sensor 10 to a signal processing circuit 11. According to this constitution, a useless signal due to the external noise is not inputted to the circuit 11, and thus the detection and analysis of a partial discharge sound are facilitated.
