A CPU core of a game machine displays a game image on an LCD, executes a game process, and performs an updating process on the game image. The thickness variation of the gate dielectric film is lowered, whereby a field effect transistor with high mobility is manufactured. In addition the control recalculates an engine operating point target based on the calculated engine speed final target and calculates an engine power final target based on the recalculated engine operating point target. The cover is partially translucent and adjacent the base track such that the rails engage with the attachment grooves. The direct connection between the display module and the data link facilitates bi-directional communication with the vehicle’s on-board computer for diagnostics as well as reprogramming of the on-board computer which may be accomplished in real-time. The pump is composed of a pump drive section, drivingly rotated by a motor, and pumping sections which perform a pump function with the rotation of the pump drive section.
