ON resistance and leakage current of a vertical power MOSFET are to be diminished. One example method comprises, adjusting a brake torque applied to a deactivated rotating engine after an engine restart request, the brake torque applied to slow the engine to at least a predetermined threshold speed without stopping the engine, and engaging a starter to the still rotating engine to increase the engine speed and restart the engine. A screw shape shaft fixedly provided with a gear disposed rotational moving line of the timing belt is provided in the frame and conjointly moved with the timing belt. The second and third pixel electrodes are arranged along a first direction parallel to a major axis of the first pixel electrode and disposed to expend along second directions perpendicular to the first direction.
