Title: Light emitting diode
Inventor: KANEDA KOICHI
IPC: H01L33/14
Filed: 1985-09-12
Abstract: PURPOSE:To obtain a surface light emitting type light emitting diode having excellent light emitting amount/current ratio by forming a current passage area smaller than the area of a light emitting window at a substrate side. CONSTITUTION:An impurity such as zinc is, for example, diffused as an impurity in an N-type GaAs substrate 12 on an N-type electrode 11 so that the diameter of a non-diffused region becomes approx. 40mum to form a current narrowing region 13. Then, an N-type AlGaAs layer as an N-type enclosure layer 14, an N- or P-type such as P-type AlGaAs layer as an active layer 15, a P-type AlGaAs layer as a P-type enclosure layer 16 and an N-type AlGaAs layer as a cap layer 17 are sequentially formed by epitaxial growth from the surface. Then, zinc is diffused approx. 100mum of diameter in the layer 17 to form a P-type side selectively diffused region 18, gold-zinc is then deposited so that the diameter of a light emitting window 19 becomes 70mum to form a P-type electrode 20. A current flows in a funnel-shaped range, and the component which flows laterally to become reactive reduces.

IPC: G11B5/41
Filed: 1984-09-28
Abstract: PURPOSE:To eliminate effectively adhered dust by controlling the rotation direction of a disc drive motor of a floppy disc device and rotating a cleaning disc in opposite direction to the normal disc rotating direction in executing the head cleaning. CONSTITUTION:In loading a cleaning disc 5 to the floppy disc device and executing a head cleaning program of a control system 1, a control signal controlling the rotation direction of a motor 4 in the opposite direction to the normal rotation direction is transmitted to a terminal (a) of a rotation direction switching circuit 2.

Filed: 1981-12-18
Abstract: PURPOSE:To enable the accurate quantification of proteins of various densities in a proportional response area of a photodetector such as a TV camera, by quantifying a  large quantity of protein after a color reaction in a short time, while quantifying a  very small quantity of protein after a color reaction in a relatively long time. CONSTITUTION:Blood protein is separated into a flat-plate shaped polyacrylamide gel  by a method of two-dimentional electrophoresis (electrophoretic separation device 1).  This gel is processed in a pre-dyeing processing tank 2, and then is immersed in a buffer water solution containing 3,3'-diaminobenzidine. Subsequently, water peroxide is  added thereto to develop the color of a separated protein spot (color-developing tank  3). A prescribed time t1 later, it is taken out in an image reader (TV camera) 4, an information on the optical concentration of an electrophoresis-separated image is analyzed by an image-analyzing device 6, and thereby a relatively large quantity of protein  component is quantified. The gel from which the reading of an image is ended is returned to the color-developing tank 3, and a color reaction is continued. Next, at a  prescribed time interval, i.e. after a time t2, the gel is taken out likewise in the image-  reading device 4, and a relatively small quantity of component is quantified accurately  without an error.

Title: Bidirectional light transmission system
Inventor: YOSHIZAWA NOBUKAZU
IPC: H04B10/077
Filed: 1989-08-09
Abstract: PURPOSE:To detect the frame of a received auxiliary signal and to identify whether the received signal is transmitted from the station of a called party or from its own station by making mutually different the constitution contents of the frame synchronizing pulse of an auxiliary signal corresponding to each terminal station. CONSTITUTION:The auxiliary signals (b) and (e) are composed of the frame synchronizing pulses F1 and F2 of K bits and the data signals of N bits, respectively. When a fault is generated in a transmission line, optical signals D and G sent from the terminal stations 1 and 2 are reflected at the faulty point, inputted to directional couplers 31 and 32 of its own station and frequency- divided. For example, in an auxiliary drop part 61 of the terminal station 1, an auxiliary signal b' is dropped from a main signal B and outputted to a frame synchronizing detection part 91. Since the detection part 91 detects the frame synchronizing pulse F1 and does not detect the F2, only an F2 detection warning signal f0 is outputted. As a result, on the terminal station 1 side, it is judged that the fault is generated in the transmission line 3.

Abstract: PURPOSE:To prevent the generation of high frequency noise generated at each conduction of triac by providing a switch circuit conducting the triac in synchronizing with a specific point of an AC power supply and disconnecting a current at a presribed point of time. CONSTITUTION:A semiconductor switch circuit 9 discharges an electric charge of a capacitor 6 through the triac 8 by switching a switch 5 and using a power supply voltage synchronizing signal from a constant voltage diode 4 from a zero volt point and stops discharge after the discharge current is decreased to a prescribed current.

When the conductive current is decreased to a prescribed current, the conduction of the triac 8 is stopped. Thus, high frequency noise generated at each conduction of the triac and the fluctuation of a load current due to the variation in trigger sensitivity of the triac are eliminated.
