Title: Method and device for monitoring lapping allowance of material to be welded for seam welding
Inventor: BABA YUKIHIRO
IPC: B23K11/06
Filed: 1990-08-24
Abstract: PURPOSE:To accurately detect a lapping allowance of the materials to be welded by obtaining resistance between electrodes from an electric current and the voltage measured and comparing it with reference resistance between electrodes. CONSTITUTION:A welding current detector 11 fitted to a primary side coil 3a of a transformer 3 detects a secondary side current and controls a constant current so that it is maintained constant. A welding voltage detector 12 fitted to a secondary side coil 3b of the transformer 3 measures the voltage between rotary electrodes 4a and 4b. A computing element 13 inputs the secondary side current and voltage measured and operates the resistance between the electrodes. A setter 14 sets and inputs upper and lower limit values of the reference resistance between the electrodes corresponding to material, thickness, etc., of the materials to be welded. A comparing and determining device 15 compares whether the resistance between the electrodes obtained by the computing element 5 is within the range of the upper and lower limit values of the reference resistance between the electrodes set by the setter 14 and decides the propriety of the lapping allowance of the materials to be welded.

Moreover, picture addresses of X and Y are calculated at address calculating sections 35 and 36 and terminations of X and Y are checked by comparators 37 and 38. Positions of each picture element from the calculating sections 35 and 36 are stored in an inputted picture memory 39 and, at the same time, supplied to a correction calculating section 40. At the calculating section 40 the nonlinear distortion of each picture element position stored in the memory 39 is corrected. Each picture element position corrected at the calculating section 40 is stored in an outputting picture memory 43. Thus the nonlinear distortion of an original picture is corrected with a simple constitution.

Filed: 1990-08-24
Abstract: PURPOSE:To prevent the occurrence of erroneous feed back control and critical conditions by judging a pressure sensor at fault based on cylinder inner pressure detected by a pressure sensor, and thereby fixing cylinder control parameters which indicate that the pressure sensor has failed. CONSTITUTION:It is judged based on cylinder inner pressure P detected by a pressure sensor 10 that the pressure sensor 10 has failed, and the control parameters of a cylinder 1 indicating that he pressure indicator 10 has failed, are thereby fixed. And when it is detected that the pressure sensor 10 has failed, the feed back control of the cylinder 1 to which the pressure sensor 10 is attached, is designed to be suspended. By this constitution, the occurrence of erroneous feed back control and critical conditions caused by the failure of the pressure sensor 10 can thereby be prevented.

Title: Semiconductor laser driving equipment
Inventor: HATA KOJI
IPC: H01S5/042
Filed: 1992-08-20
Abstract: PURPOSE:To prevent deterioration and breakdown of a semiconductor laser regardless of supplying and cutting-off of a power supply. CONSTITUTION:A current flowing in a resistor 336 connected between a terminal TP1 and a terminal TP2 when a transistor 342 turns on is supplied to a semiconductor laser. A power supply wherein a regulator 359 turns on when transistors 356, 357 turn on is supplied to the terminal TP2. When the power supply is cut off, the transistor 357 turns on, the transistor 356 turns off, and the regulator 359 turns off. Hence the potential of the terminal TP2 is indefinite, the potential difference between the terminals TP1 and TP2 is decreased, the transistor 342 turns on, and current supply to the semiconductor laser is cut off. Thereby deterioration and breakdown of the semiconductor laser can be prevented regardless of supplying of cutting-off of the power supply.
