摘要： A control device for a belt continuously variable transmission with a primary pulley, a secondary pulley and a V-belt, includes an oil pressure control unit which applies a thrust to each of the primary pulley and the secondary pulley, and a controller. The controller judges whether or not a pulley ratio is less than 1. When the pulley ratio is less than 1, the controller sets a target thrust of the secondary pulley on the basis of an input torque to the primary pulley and a coefficient of static friction between an element forming the V-belt and the secondary pulley, and then to instruct the oil pressure control unit to apply the target thrust to the secondary pulley. When the pulley ratio is at least 1, the controller sets a target thrust of the primary pulley on the basis of the input torque to the primary pulley and a coefficient of dynamic friction between the element forming the V-belt and the primary pulley, and then to instruct the oil pressure control unit to apply the target thrust to the primary pulley.

摘要： A pulse welding apparatus using a pulse discharge such as a pulse arc welding apparatus and a short-circuit transfer arc welding apparatus. A pulse current waveform control circuit, which controls the pulse arc current so that a desired pulse arc current is supplied to the arc welding power supply for outputting the pulse arc current to the welding load unit, is constructed such that the optimum welding operation may be performed without having to adjust circuit components and modify circuit design. The pulse current waveform control circuit is in the form of a microcomputerized digital circuit which operates under a program to provide a desired pulse arc current. A modification of the program can provide any desired pulse arc currents without changing circuits. The optimum welding current waveform parameters or a target arc length signal is learned in the first welding stage and stored into a memory. An arc length feedback control or a current waveform control is performed under the control of program on the basis of the optimum welding current waveform parameters or the target arc length signal so as to control the faulty separation of globules when magnetic blow occurs and so as to reduce the variation of arc length due to external disturbances occurring at the welding torch so that improved welding quality is ensured under various environment.

摘要： A pulsed arc welding for carrying out arc welding or short-circuit transfer type arc welding by utilizing the pulsed discharge generated at the tip of a wire electrode. The propensity of wire electrode curvature causes irregular changes in the contact point of the wire electrode and variations in the arc length between the wire electrode tip and workpieces. Consequently, the invention detects arc voltage and current and checks the instantaneous variation in the arc length. The arc voltage value thus detected is converted to a reference arc voltage variable. Then the detected arc voltage value is compared with the reference value to compute a true arc length. A simulation arc length signal, which varies as welding proceeds, and a reference simulation welding current waveform are set, to compare the simulation arc length signal with the computed arc length signal. The reference simulation welding current waveform is corrected according to this difference signal to form and output a welding current waveform, which is controllable instantaneously to provide an ideal target arc length. Welding can be carried out with stability since the wire electrode is allowed to hold the simulation arc length during each welding process.
