Title: Laser beam machine
Inventor: YOSHIDA TOSHIO
IPC: B23K26/06
Filed: 1987-02-20
Abstract: PURPOSE:To prevent supply of overcurrent to an amplifier by fitting a laser beam generation means for detecting and a detector to a supporting plate of a resonator mirror to monitor the alignment and absorption loss of a resonator. CONSTITUTION:The laser beam generation means 13 for detecting and the detector 15 are fitted to the supporting plate 12 to support a total reflection mirror 2. Then, a laser beam 14 from the generation means 13 is projected on a partial reflection mirror 3 and a reflected laser beam 16 is made incident on the detector 15. Accordingly, the voltage in proportion to the beam quantity of the laser beam and the voltage in proportion to the dislocated position from the reference position of the laser beam are detected with the detector 15. Since these voltages show the absorption loss due to a stain of the mirror 3 and the quantity of deviation of a set angle, if a resonator abnormal signal is outputted when the voltage is over a prescribed value, supplying overcurrent to the amplifier 1 is prevented and damage of the lamp and deterioration of service life is prevented.

IPC: H02K11/00
Filed: 1984-03-02
Abstract: PURPOSE:To always optimally control AC motors by measuring various impedances of the motors and deciding the calculated constants of controlling a converter on the basis of the measured results. CONSTITUTION:A coordinates converter 4 calculates on the base of a current command signal and the signal of an oscillator 3, and outputs 2-phase current command pattern signals. These pattern signals are compared with a current detection signal in the respective phases, and the GTO of an inverter is controlled ON or OFF in response to the deviation. On the other hand, the AC/DC two axial components of the motor voltage are detected by a voltage component detector 8. A motor constant calculator 9 outputs a command signal, holds the output current of the inverter at the prescribed value and measures the electric constants of the motor.

Abstract: PURPOSE:To unite this photodetector to other semiconductor element and to realize an output of a large electric current by a method wherein a light waveguide layer used to optically detect incident light is formed as one part of a collector layer between the collector layer and a base layer. CONSTITUTION:A light waveguide layer 3 used to optically detect incident-light is formed as one part of a collector layer 2 between the collector layer 2 and a base layer 4. When the light waveguide layer 3 used to detect the incident light is formed as a semiconductor layer, it can be easily formed collectively with other semiconductor elements and a forward bias is applied between an emitter and a base. In addition, since a potential barrier is lowered, a stream of electrons, on the side of the emitter, flowing to the side of a collector over a base region is increased; a large electric current can be caused to flow.

Abstract: PURPOSE:To quickly execute operation by making it possible to specify the number of gate circuits for finding out exclusive OR between the input of a certain digit of a binary number to be added and a carry input from a lower digit. CONSTITUTION:An exclusive OR circuit XOR2 finds out exclusive OR between inputs X3, X4 out of the inputs X1 to X4 of certain digits of a binary number to be added and an exclusive OR circuit XOR3 finds out exclusive OR between the output of the circuit XOR2 and a carry input Cin from the lower digit.
