    摘要: A can lid of the fully-open type has a disk-shaped panel, a score notched endlessly in a surface of the panel along an outer circumferential edge of the panel, for forming an opening in the panel, and a tab fixed to the panel by a rivet. The tab is attached in a direction substantially perpendicular to an initial tear-off line of the score. The surface of the panel which is concealed from view by the tab is printed with a circular mark representing a rolling direction in which the material of the panel has been rolled. The score is defined such that the rolling direction extends substantially at a right angle to the initial tear-off line of the score. The panel has an auxiliary score defined in the surface thereof near the rivet and positioned across the rivet from the initial tear-off line substantially parallel to the initial tear-off line and separate therefrom.

    摘要: The present invention provides a MOS-type variable capacitance element which can obtain a sufficient capacitance valuable width and, at the same time, can eliminate restrictions imposed on a control voltage range. A MOS-type variable capacitance element includes a MOS transistor in which an N well having polarity opposite to polarity of the P type is formed on a P type semiconductor substrate, a pair of source and drain regions are formed in the inside of the N well, an N-type high-concentration region is formed in the inside of the N well, a gate oxide film is formed on the N well, and a gate electrode is formed on the gate oxide film, a first electrode which connects the source and drain regions to a reference potential, a second electrode which is connected to the gate electrode, and a third electrode which is connected to the N well and applies a control voltage having polarity equal to polarity of the P type to the N well using the reference potential as a reference, wherein a variable capacitance element is provided between the second electrode and the third electrode.
