    Abstract: A double-tuned circuit includes a primary side tuned circuit 10 having a first air-cored coil (L2) and a secondary side tuned circuit (11) having a second air-cored coil (L3). The first air-cored coil (L2) and the second air-cored coil (L3) are opposed to each other so that one opening end of the first air-cored coil (L2) and one opening end of the second air-cored coil (L3) are capable of being coupled to each other on a coil mounting surface. The coil mounting surface is provided with a first conductive pattern (12) formed adjacent to the first air-cored coil (L2) in a direction perpendicular to an arrangement direction of the first and second air-cored coils (L2, L3), and both ends of first conductive pattern (12) are connected to a ground.

    Abstract: A structure of a vibrator to increase reliability in an electrical connection between power supply terminals of and circuit board electrodes of the vibrator, and to improve mounting efficiency of the vibrator on a circuit board. In the structure, the terminals are constructed from twisted coil springs, and contact portions of the terminals, which portions are in contact with the electrodes, are made in a winding form. The twisted coil springs each are wound around a pivot pin, and steps as clearance for the contact portions and surface portions to which the contact portions are opposed face to face are provided. However, alternatively to the steps and surface portions above, any of the following structures can be adapted: providing a partition plate between two power supply terminals, or surrounding spaces, in which the contact portions can elastically deform, by insulative box members, or extending the twisted coil spring portions to the contact portions asymmetrically in a positive and a negative electrode so that, when the power supply terminals are elastically deformed, each of the contact portions to be deformed more outward than each of the coil spring portions.

    Abstract: In an oscillator circuit employing a pattern coil on a printed-wiring board as a resonator circuit, in order to satisfactorily adjust dispersion in oscillation frequencies, an air-core coil wound by more than half a turn and less than one turn is provided so as to be connected to the pattern coil in parallel and planted on the printed-wiring board, and the oscillation frequency is adjusted by adjusting the angle of the air-core coil relative to the printed-wiring board.
