A hair dryer apparatus and method for use in hair care. A metal plate is inserted into the support part so as to increase rigidity. The transmitter section is operable to convert an outbound symbol stream into an outbound wireless signal. A plurality of radially extending flanges is formed about the circumference of the distal end. When the two selection transistors are in off-state, a potential can be supplied to the source or the drain of the pass transistor via the precharge transistor, and by electrical conduction, another potential for a context is applied to the gate of the pass transistor.
