IPC: G11B7/00
Filed: 1986-05-14
Abstract: PURPOSE:To eliminate misrecording and to improve the reliability of a system by driving a laser with the output of a sample holding means which holds and outputs a monitor signal during the movement of an optical system including the laser. CONSTITUTION:A switching circuit 11 is closed in a normal playback state and a resistance 10 and the emitter of a Tr3 are connected mutually under a switching command 14, so that the driving current I2 of the laser 1 is controlled by conducting it through the Tr3. Then when the optical system is moved, a sampling command 13 is inputted to the sample holding circuit 12 to hold the monitor signal and then a hold signal 16 is outputted. Therefore, the Tr3 and a Tr18 become equal in base potential and the resistance and the emitter of a Tr11 are connected mutually under a command 14, so that the same current as the current I2 is conducted to the laser 1. Consequently, even if no monitor signal is sent back owing to the movement of the optical system, the misrecording to a recording part, etc., is eliminated and the reliability of the system is improved.

Title: Press-pinching detector
Inventor: YAGUCHI OSAMU
IPC: G01L1/20
Filed: 1989-04-28
Abstract: PURPOSE:To enhance detection accuracy by preventing erroneous detection caused by environmental change or secular change by generating the pressure detection voltage having the magnitude corresponding to the pressure applied to a pressure-sensitive element and performing the detection based on the fluctuation of said voltage. CONSTITUTION:A variable resistor whose resistance value changes corresponding to pressure is provided to a pressure-sensitive sensor 1 as a pressure-sensitive element 4. A pressure change detection circuit 10 detects the magnitude of the pressure applied to the sensor 1 on the basis of the resistance value Rv of the element 4 to output the detection voltage Vs corresponding thereto. Fur ther, a condensor 14 cuts off the DC component of the voltage Vs outputted from the circuit 10 to take out the same. The output voltage VQ of the con denser 14 is not outputted when the resistance value Rv of the element 4 changes gently but outputted only when the change of the resistance value Rv is sudden. Therefore, when detection is performed on the basis of the voltage VQ, detection based on a change of pressure but not on the magnitude of pressure becomes possible and, even when the resistance value Rv is changed by secular change or temp. change, the erroneous detection due to said change can be prevented.

Title: Semiconductor device and its manufacture
Inventor: TAKAHASHI TAKESHI
IPC: H01L29/205
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To increase current gain and improve reliability by forming a high potential barrier to majority carrier of a base layer by a first emitter layer, and forming an emitter protection layer which is excellent in crystallinity on the emitter layer. SOLUTION: A high potential barrier is formed to a hole which is majority carrier of a base layer 18 by an emitter layer 20 formed of an n-InGaP layer. Since hole which is majority carrier of the base layer 18 is thereby hard to flow into the emitter layer 20 even if impurity concentration of the base layer 18 is raised, a large current gain can be obtained. Furthermore, III-V compound semiconductor including In produces conductive reactant when it is oxidized, and it is not desirable that a III-V compound semiconductor including In is exposed in a surface for ensuring reliability of a semiconductor device. Therefore, a surface of the emitter layer 20 is covered with an emitter protection layer 22 for preventing oxidation.

Filed: 1980-08-12
Abstract: PURPOSE:To prevent inspection objects from colliding with each other and being damaged, by a method wherein a magnetic substance is provided close to a housing base of a housing magazine case. CONSTITUTION:A housing part of a transfer mechanism of semiconductor IC devices, such as transfers them to the measuring equipment, consists of a housing  base 8, a magazine case 9 and a magnetic substance 11 which is placed close to an  arbitrary position of the base 8. Said semiconductor IC devices to be tested are  transferred to the top end of the magazine case of the housing part and drop inside  the case naturally but they stop clropping or reduce the dropping speed because of  the contraction force of the magnetic substance 11 when they come near the substance 11. Thus the ceramics parts of said devices are prevented from being broken  or cracked.

Abstract: PURPOSE:To confirm exactly a complicated waveform distortion, and a responsiveness against a higher harmonic content which increases and decreases suddenly, by recording the current waveform of a real system, as an electric signal in a recorder, reproducing it, and applying it as a detecting signal. CONSTITUTION:As for a device to be tested AF, its output terminal is connected to a testing bus l, and a recorder FR is connected to a detecting signal input terminal.

The device to be tested AF receives this signal, executes a higher harmonic analysis, and a compensating current IO is generated in order to eliminate a higher harmonic component. In this state, the operation is inspected by comparing the current waveform of the bus l and the waveform of the detecting signal ID.
