An electronic component includes: an oscillation circuit that is electrically connected to a resonator element; and a substrate that includes a first surface on which the oscillation circuit and wiring that is electrically connected with the resonator element and the oscillation circuit to form an oscillation loop are disposed, and a second surface opposite to the first surface. The demands have multiple due dates, and the multiple due dates have different priorities. A plurality of terminal electrodes is provided on the first surface of the base. Corresponding apparatus and a computer program are also provided. The second end of the helical drive engages a bearing mounted to a stationary bracket mounted to the door opening structure. An alphanumeric keypad 14 is carried by the housing 12.
