Abstract: PURPOSE:To obtain a carbon dioxide gas laser capable of obtaining effective laser light ray by disposing a photodetector in the vicinity of a discharger, detecting the generation of an arc discharge due to the variation in the quantity of light, and regulating a discharging current supplied to the discharger, thereby suppressing the generation of an arc discharge and preventing the consumption and damage of the electrodes. CONSTITUTION:A plurality of arc detectors 10 are disposed in the vicinity of a discharger 5, and the output is inputted to an arc detector 11. Further, an arc detection signal outputted from the detector 11 is processed by a signal processor 12 so as not to cause an error detection due to the disturbance light, and applied to a controller 13. The controller 13 outputs a control signal to an SCR control unit 14 to regulate the discharging current of the discharger 5 in response to the output from the processor 12. The unit 14 generates a phase pulse in response to the control signal, and applies it to the gate of an SCR to control the phase of a power source AC 200V. Thus, the phase controlled voltage is applied from a high voltage stepup transformer 15 through a high voltage rectifying and smoothing cirlcuit 16 to the discharger 5, and supplied through a discharging stabilizing resistor R to discharging electrodes 6a, 6b.

IPC: H02P8/38
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To diagnose the output accurately by performing diagnosis while avoiding the time when the level at the output terminal is inverted through induction between windings in a stepping motor. SOLUTION: Pulses are outputted sequentially from the output ports 10-40 of a microcomputer 5 at a predetermined period. Based on the pulses, a drive circuit 3 turns the phases A-/B of a stepping motor 2 on/off. A diagnostic circuit 4 provides the microcomputer 5 with signals 1I-4I corresponding to the terminal level of the phases A-/B. When the output from the microcomputer 5 is Lo level, corresponding output terminal level of the stepping motor is equal to the battery voltage and a decision is made that the stepping motor is normal it the input level to the microcomputer 5 is Hi otherwise the stepping motor is abnormal. Since no current flow through phase A when diagnosis is made immediately before outputting a drive pule, phase A can be diagnosed accurately.
