A claw pole type motor includes a rotor having a magnet arranged on an outer circumferential surface thereof and a stator including an annular iron core and an annular coil received within the iron core. The adjustable hand rest attachment incorporates an articulated hand rest post to allow for varying angles of adjustment. An input node of the clocked inverter is connected to the bit line while an output node is connected to a data line. A high-frequency wave is generated by an inverter 13 based on the DC voltage supplied from the converter 12, and a dielectric barrier discharge is induced in the dielectric barrier discharge lamp 14 to irradiate ultraviolet rays.
