Title: Method for controlling resistance welding current
Inventor: HIBINO TETSUHISA
IPC: B23K11/25
Filed: 1982-04-16
Abstract: PURPOSE:To stabilize the quality of welding, by dividing the control in one current conduction period to 3 periods, assuring the route for the current conduction meeting the electrode consumption after the start of melting and supplying adequate current density. CONSTITUTION:The welding current control in one current conduction period of resistance welding is divided to three control periods. In the 1st period, constant current control is accomplished for a prescribed time, and the degree of electrode consumption is estimated from the max. value of the resistance value between tips obtained at that time, then the next target value is determined. In the 2nd period, the resistance value is subjected to feedback control until the resistance value between the tips attains the target value or below and the route for the current conduction meeting the degree of the electrode consumption is assured. In the 3rd period, the voltage value is subjected to feedback control so that the voltage between the tips follows up the curve of the targe voltage value and adequate current density is supplied. The quality of welding is thus stabilized.

Filed: 1984-03-31
Abstract: PURPOSE:To perform stable developing operation by providing a conductive rubbing member which rubs against the surface of an image carrier before a developing process, and making this rubbing member conductive to a part having a lower potential than the surface potential of the image carrier through the developer in a developing device. CONSTITUTION:When the developer D contains high-resistance toner sufficiently, the resistance of the developer D between a developing sleeve 9 and a conductive member 12 is nearly equal to the resistance value of the toner and an electrostatic latent image is never disordered even when a destaticizing brush 11 contacts the photosensitive body 1. When, however, the toner is consumed gradually until the developer D between the sleeve 9 and member 12 decreases in toner density, the resistance of the developer D decreases and approximates to the resistance value of carriers and then charges on the photosensitive body 1 flow from the destaticizing brush 11 to the earth side through the conductive member 12, developer D, and sleeve 9 to reduce the difference between the surface potential of the photosensitive body 1 and the potential of the developing sleeve 9. Consequently, copy density decreases, but no carrier attraction is caused.
