Title: Arc welding machine
Inventor: TAJIMA SHINJI
IPC: B23K9/10
Filed: 1986-06-27
Abstract: PURPOSE:To discriminate an arc state from a short-circuited state at the time of welding regardless of inductance of a wiring cable between a welding power source and a torch by discriminating whether or not a ratio of a peak value of the positive voltage induced at the time of accumulating the energy of a reactor for smoothing an output power source to an absolute value of a peak value of the negative voltage induced at the time of giving off the energy is more than a prescribed value. CONSTITUTION:The positive voltage induced at the time of accumulating the energy of the reactor 27 for smoothing an output electric current is inputted to a circuit 32 via a diode 31 and the peak value VP of the positive voltage outputted from the circuit 32 is added to a comparator 36 as it is. On the other hand, the negative voltage induced at the time of giving off the accumulated energy of the reactor 27 is inputted to a circuit 34 via a diode 33 and the peak value VN of the negative voltage outputted from the circuit 34 is inversed by an inversing amplifier 35 and amplified and added to the comparator 36. Then, when a ratio of VP/VN to be a discriminating reference of arc/short-circuit is more than the prescribed value, the output of a H level which is a detected signal of the short-circuited state is produced on the comparator 36 and when the ratio of VP/VN is less than the prescribed value, the output of a L level which is the detected signal of the arc state is produced on the comparator 36.

Filed: 1982-08-30
Abstract: PURPOSE:To radiate an electron beam to a predetermined position by correcting the deflection signal quantity only by a correction amount obtained in response to the deflection data to a deflection unit and analysis voltage data when the analysis voltage of an energy analyzer is changed. CONSTITUTION:An electron beam 2 is scanned by a deflection unit 1 to be radiated to a sample 3 on an XY stage 4. Secondary electrons from the sample 3 are detected by a detector 7 constituting an energy analyzer 6 and fed to the mark detection circuit 16 of a correction data generation circuit through an ADC 19. The analysis voltage is applied from the circuit 16 to an analysis grid 8 through a DAC9 and scanned for mark detection through a DAC12 for each analysis datum. The mark position coordinates data are compared with the reference analysis data by a calculation circuit 18 to calculate the correction data, which are stored in a correction data memory unit 11a. The data read out of the unit 11a and added 14 to the deflection voltage from the DAC12 to be fed to the deflection unit 1, thus allowing to radiate the electron beam to a predetermined position even when the analysis voltage is changed.
