Abstract: An induction heating system includes induction heating apparatuses, each including a high-frequency current transformer, a low-frequency current transformer and a heating coil, a high-frequency input switch connected to the high-frequency current transformer, a low-frequency input switch connected to the low-frequency current transformer, a first power source to output a high-frequency electric power and a low frequency electric power, a second power source, a first power source output switch connectable to the first power source, a second power source output switch connectable to the second power source, and a switch controller. Each induction heating apparatus includes a heater controller to send a signal to the switching controller to turn on one of the first power source output switch and the second power source output switch, to turn off the other, and to switch on or off each of the high-frequency input switch and the low-frequency input switch.

Abstract: A method of manufacturing a lead wire for a solar cell includes heating a wire material by a direct resistance heating or by an induction heating to reduce a 0.2% proof stress of the wire material while conveying the wire material and plating the wire material that is in a heated condition obtained by the direct resistance heating or by the induction heating while further conveying the wire material. An apparatus is configured to implement the method, and includes a plating bath, a conveyor mechanism configured to convey the wire material, a heater configured to heat the wire material, and a controller configured to control the conveyor mechanism and the heater.

Abstract: A current applying apparatus includes a pair of electrodes configured to contact a workpiece to apply an electric current to the workpiece, and a bus bar arranged to extend along the workpiece. At least one of the electrodes includes a moving electrode configured to move relative to the bus bar and the workpiece such that an electric current flows between the bus bar and the workpiece through the moving electrode, the moving electrode being connected to the bus bar so as to be movable relative to the bus bar, and the moving electrode being configured to contact the workpiece so as to be movable relative to the workpiece.
