A system for providing franking services includes one or more networks, one or more postage meters, and a postal infrastructure data center connected to the one or more meters through the one or more networks, wherein the postal infrastructure data center establishes communication with the one or more meters as required. One method of the present invention comprises powering the oscillator. A resist composition comprising the polymer as a base resin is sensitive to high-energy radiation and has excellent sensitivity, resolution, and etching resistance. According to the method, wafers can be stably separated from each other while pads of a semiconductor device are protected, so that stabilization in the fabrication process can be realized and pad corrosion caused by DI water is prevented during a sawing process. The inductor is energized to perform a magnetic pulse welding operation to secure the end of the driveshaft tube to the body portion of the yoke without generating a significant flow of air toward the inductor.
