The ergonomic handle for a fuel cap pivotably engages to a top surface of the cap and is movable between a stowage position lying against part of the top surface of the cap and engaging against and activating a locking mechanism of the cap upon pivoting into such stowage position, and an upright functional position where the handle is pivoted to a position perpendicular to the cap. The second display control section processes an output signal from the first display control section to be displayed on the display section. The method and apparatus are able to acquire a signal with extremely small interference and acquire a higher mobile performance. The dielectric layers may include oxide-nitride-oxide layers that function as a charge storage structure for the memory device.
