Openings are each make on the regions 2 and 3 and electrodes are formed in contact with the openings. To produce the electrodes, first, a metal film 7 made of a substance selected among from Cr, Ti and Mo is applied for the bottom layer by the electron beam evaporation. Then a metal film made of a substance selected among from Al and Ni is applied on the layer for the top layer while an intermediate layer 8 made of an alloy of those substances used for the two layers is allowed to form between the films 7 and 4. With such an arrangement, a strong adhesiveness is developed in the intermediate layer 8 thereby eliminating peeling. In addition, a better bonding property can be obtained for the top layer.

Abstract: PURPOSE:To surely add specific information in one and same track by detecting the number of specific information recording sections in one track and then recording specific information. CONSTITUTION:At the time of writing a new directory to a track on which a directory 321d is stored and in case of reading a track having the directory 321d once in a direction F over the entire card length, the level of a signal 315-1 in outputs 315-1, 315-2 of a IGD 315 goes to a high level in response to the change in a demodulation signal 305-8 and the signal 315-2 goes to a high level for a prescribed time while detecting the trailing of the signal 315-1. As the writing method, after the directory 321d is read, in scanning the track in the direction F again without track change, the signals 315-1, 315-2 appear again similarly as the directory is read. Since one directory is used, when the signal 315-2 goes to a low level, the start of write of the new directory is started. Thus, the writing of plural directions in one track is attained.

Abstract: PURPOSE: To prevent the video locations of the image for which a picture element shifting is performed and the basic image for which the shifting is not performed from being different by inhibiting the control of an image pickup state changing means when a high resolution image pickup is detected. CONSTITUTION: The control part 103 of a video input device main body 101 monitors the operation signals 108 to 110 generated by always operating a PP switch 104, a pan/tilt switch 105 and a zoom switch 106 by an operator. An object to be detected at first is a PP operation signal 108 and whether the high resolution input by a light transmission parallel plate(PP) 112 is performed or not is detected.

IPC: H01S5/323
Filed: 1990-06-05
Abstract: PURPOSE:To obtain a high reliability semiconductor light emitting device which eliminates oxidation during performance by forming a compound semiconductor layer on a substrate which comprises a single crystal of Si1-x Gex (0<=x<=1). CONSTITUTION:Si1-x Gex (x=0.75), whose lattice constant is small, is adopted as a substrate while GaAs1-x (x=0.25) is used as a growth buffer layer. Ga0.64 In0.36P, which is lattice-aligned with the substrate 2 is used for a active layer while Al0.64In0.36P is used for a clad layer 7. Therefore, this construction increases the difference of band gap energy between the active layer 6 and the clad layer 7 so that short oscillation wavelength maybe obtained without the application of aluminum for the active layer. As a result, it is possible to minimize performance deterioration caused by oxidation during performance and hence provide a high reliability semiconductor light emitting device.
