A method and system for transmitting engine control data to or from the engine control unit of an engine. An adjusting device may adjust the follower relative to the base member to partially extend the cutting member out of the outer peripheral portion of the carrying member for suitably machining the work pieces. The illumination capacitor may be charged to a first voltage and a boost capacitor of the capacitive voltage divider circuit may be charged to a second voltage that is a fraction of the first voltage. Also, when a P type body layer 19 is formed, an interface between the P type body layer 19 and an N-epitaxial layer 18 is located at a deeper position than a bottom end of the gate electrode film 11. The discharging part includes a discharge transistor and an auxiliary transistor. Also included is a method for treating cancer in a human which comprises administering to the human subject an anti-cancer effective amount of any of the compounds listed above in combination with an anti-cancer effective amount of other conventional chemotherapeutic agents.
