An embodiment of the present disclosure provides a method to reduce acoustic vibration in a multilayered capacitor stimulated by a radio frequency signal by placing a first capacitor layer adjacent to second capacitor layer sharing a common electrode such that the acoustic vibration is reduced by applying one or more anti-acoustic vibration bias voltages to the multilayered capacitor. Other embodiments are disclosed.

The invention comprises a technique and associated mechanisms by which dielectric resonator circuits, such as filters, can be tuned in both frequency, bandwidth or both without the need for irises, tuning screws and / or tuning plates. In accordance with the invention, the positions of the dielectric resonators are adjustable relative to each other within the cavity in multiple ways, including vertically and horizontally. The dielectric resonators also may tilt relative to each other. Furthermore, an off-center longitudinal hole can be machined in one or more of the dielectric resonators so as to make the electromagnetic field of the resonator non-uniform so that the dielectric resonator can be rotated about its longitudinal axis to alter the coupling between dielectric resonators. In accordance with another aspect of the invention, frequency tuning can be accomplished by using two separate dielectric resonators adjacent each other, one on top of the other, and adjusting the vertical spacing therebetween to achieve the desired center frequency within that dielectric resonator pair.

An inductor of the present invention includes a plurality of insulating layers being stacked and coil patterns respectively provided on predetermined layers of the insulating layers. The coil patterns are provided on at least two of the insulating layers, and electrically connected to each other. With this arrangement, it is possible to improve Q of the inductor without increasing the size of the inductor.

Apparatus comprises a tuning fork having first and second tines, a first magnet disposed on the first tine, and a second magnet disposed on the second tine. In one embodiment the magnets comprise permanent magnets; in another they comprise electromagnets. In a preferred embodiment the magnets have magnetic moments oriented essentially parallel to the axis of the tines and anti-parallel to one another. In operation, the apparatus is made to oscillate at or near its resonant frequency, and in the presence of a magnetic field a parameter of the oscillation (e.g., its frequency, phase or amplitude) is altered in a fashion that allows the magnitude or direction of the magnetic field to be determined. In a preferred embodiment, the tuning fork is disposed within a vacuum enclosure, which increases the Q of the apparatus.

An electronic component includes first and second resonators provided within a layered substrate including stacked dielectric layers. The first resonator includes resonator-forming conductor layers of a first type and a second type. The resonator-forming conductor layers of the first type and the second type are reversed in relative positions of the short-circuited end and the open-circuited end, and are alternately arranged in the stacking direction of the dielectric layers. An input terminal is connected to all of the resonator-forming conductor layers of the first type. The second resonator includes resonator-forming conductor layers of a third type and a fourth type. The resonator-forming conductor layers of the third type and the fourth type are reversed in relative positions of the short-circuited end and the open-circuited end, and are alternately arranged in the stacking direction of the dielectric layers. An output terminal is connected to all of the resonator-forming conductor layers of the third type.
