Title: Semiconductor laser element and modulation method
Inventor: KAYANE NAOKI
IPC: H04B10/54
Filed: 1989-06-29
Abstract: PURPOSE:To enable high speed modulation by covering the periphery of an active layer with an organic insulating film and reducing parasitic capacitance outside the active region and leakage of modulated signals. CONSTITUTION:An active layer 2, a p-type InP clad layer 3, a cap layer 4 are successively grown on a substrate 1. Then, a part including the active region 2 is left as it is and the periphery thereof is removed by etching, and a p-type InP layer 3 is again grown. Further, an organic insulating film 6 is applied, and evaporated to form an electrode metal element. Then the electrode metal in the central part of the element is removed to divide it into electrodes 7, 8 forming current injecting means. Since the periphery of the active layer 2 in this laser element is covered with the film 6, parasitic capacitance outside the active region 2 is reduced. When the current ratio at the electrode 7, 8 of the laser element is held at the predetermined value and a modulated signal is applied to the electrode 7 having low current value, good frequency characteristic can be obtained and high speed modulation is enabled.

Abstract: PURPOSE: To make possible to reduce the size and weight of a measuring unit and carry out high accuracy measurement by accumulating the data about a duration of sunshine in an electric current integrating module which constitutes the measuring unit.  
     CONSTITUTION: With a changeover switch 40 turned to a solar cell 10 side, a measuring unit MU is placed at a position to measure the duration of sunshine.

Title: Automatic music selector device for tape recorder
Inventor: SUEYOSHI MITSUSHI
IPC: G11B27/22
Filed: 1978-12-19
Abstract: PURPOSE: To secure the accurate counting of the silence parts at all times by blocking the signals sent from the silence detection circuit when the temporary pause mode is given.  
     CONSTITUTION: Silence detection circuit 1 detects the silence parts of the magnetic tape, and these detected silence parts are counted by counter circuit 2. Then a comparison is given between the desired music number memorized in memory circuit 3 and the count number of circuit 2. And when the coincidence is obtained, the desired music number is reproduced, and other music numbers are set under the high-speed reproduction mode. In such way, the automatic music selector device is formed. Now if the temporary pause mode is secured under the reproduction or the high-speed reproduction, FF10d is reset during the operation time by retrigger mono-multi 10c featuring the longer operation time. Accordingly, no count pulse is generated from circuit 1. Thus the miscount due to the temporary pause mode can be prevented, and thus the silence parts can always be counted accurately.

Title: Fine processing method
Inventor: HAMANAKA SUKEAKI
IPC: C23F4/04
Filed: 1984-08-10
Abstract: PURPOSE:To subject a thick plate material to fine processing with high processing accuracy by forming photoresist films of the same pattern to the same positions on both surfaces of the thick flat plate, stopping etching in the mid-way and changing over the same to laser beam processing. CONSTITUTION:The photoresist films 2 of the same pattern are provided to the same positions on both surfaces of a material 1A to be worked (thickness t2) which is a flat plate in etching of the flat plate which is the thick plate material or hardly etchable material. The etching is stopped at the point of the time when a bridge 7 attains a target thickness (t3) by etching. After the films 2 are removed, the bridge 7 of the part required to be removed is removed by the laser beam 13 of the scanning system in which the same pattern as the etching pattern is stored. The generation of the deviation between the upper and lower patterns and shear droops is thus prevented and the fine processing without notching, stepping, etc. in the stage of lamination is thus executed with high working accuracy.
