Title: Control method and apparatus for welding arc heat
Inventor: MAEHATA HIDEHIKO
IPC: B23K9/095
Filed: 1977-12-17
Abstract: PURPOSE: To form well-penetrated bead of a stable form by limiting the incoming  heat of welding arc by changing continuously or optionally the pulse width and  pulse repetition number of pulse current on automatic base.  
     CONSTITUTION: The condition of the weldig gap 4 is converted into the voltage signal v by the optical or supersonic edge detector 6 and the signal treatment device 7, and the arithmetic circuit 8 dispatches the value V obtained by deducting the detected signal Vo from the set signal Vr of the set value 9. The output voltage V is put in a voltage-frequency convertor built in the pulse-generating circuit 10, from which frequency fp corresponding to the input voltage is generated. Thus, the pulse repetition number fp is modulated according to the edge condition. The pulse frequency fp is sent through the amplifying circuit 11 to the switching circuit 5 to actuate the circuit 5. As the pulse frequency fp rises, the width of welding bead is reduced and the depth of penetration is increased. The DC power source 1 generates a pulse current from direct current to more than 10 Hz through the circuit 5.

Abstract: PURPOSE:To record desired video signals on a recording tape from a reproducing tape of a reproducing device by transmitting a temporary stop release command signal after a user sends a rewind signal to the reproducing device and transmitting a temporary stop setting instruction signal to a recorder after a prescribed time from the transmission of the signal. CONSTITUTION:When a switch 15 is pushed, a CPU 11 outputs a reproducing command signal, an LED 14 converts it to an infrared ray and a video camera starts a reproducing. A user retrieves a desired cut while watching the reproduced picture and pushes an editing button 12. If he wishes to rewind and to start a reproducing against the video camera, the CPU 11 transmits a rewind and reproducing command signal for the duration of two to three seconds when the button 12 is pushed and as a result, the camera is rewound and reproduced for the duration of two to three seconds. When he wishes to stop the recording on the recorder, the recorder is stopped by a temporary stop signal. the CPU 11 transmits a temporary release instruction signal and a recording is restarted after a prescribed period which is set by a rotary switch 13. The operations are greatly simplified because the editing is performed only using the button 12.
