摘要： A method of controlling the synchronized movement of a backing shoe in an automatic one-side welding of the type in which a light-transmittable backing material is placed in close contact with the back surface of the welding joint and a backing shoe adapted to be moved along with the movement of a welding apparatus is pressed through the backing material against the back surface of the welding joint just below a welding electrode whereby effecting the welding. The method employs photoelectric detectors which are embedded in the surface of the backing shoe contacting the backing material at four positions, i.e., right-front, right-back, left-front and left-back positions just below the electrode with respect to the direction of welding and the detectors are arranged at predetermined distances from each other, whereby the light emitted from the back surface of the welding joint and transmitted through the backing material is received by the detectors each of which generates an electric signal corresponding to the received light magnitude and the speed of travel as well as the lateral position of the backing shoe are controlled in such a manner that the below-electrode-point is maintained at a predetermined position among the light receiving positions on the backing shoe.

摘要： To realize power supply to each gate drive circuit without using an individual dedicated power supply for each gate drive circuit. A power conversion apparatus includes an individual drive unit that does not require a dedicated power supply, and includes gate drivers connected to switches and interface circuits and a power converter gate drive configured with a common power supply for supplying power to the gate drive unit. Power is supplied from main circuits or a number of common power supplies fewer than that of the number of the switches through one or more power supply terminals included in the interface circuit. Also, the signal can be transmitted by isolation from a signal source to the gate drivers.
