摘要： An object is to provide a resonator and a vibrator with a high Q value in which dissipation of vibration energy in vibration of the vibrator is small, and a thickness of a support part of the vibrator of a beam structure is made thicker than a thickness of the vibrator and the support part is formed in axisymmetry with respect to a length direction of a beam. By this configuration, brittleness of the support part is improved and loss of vibration energy from the support part is reduced and also loss of vibration energy resulting from surface roughness of a surface of the vibrator can be reduced, so that a resonator having a high Q value can be provided.

摘要： A switch comprises voltage applying means for providing direct current potentials to first to third beams arranged with a spacing slightly distant one from another, and electrodes for inputting/outputting signals to/from the beams. By controlling the direct current potential provided to the beam, an electrostatic force is caused to thereby change the beam positions and change a capacitance between the beams. By causing an electrostatic force between the first and second beams and moving the both beams, the first and second beams can be electrically coupled together at high speed. Also, an electrostatic force is caused on the third beam arranged facing to the first and second beams, to previously place it close to the first and second beams. When the electrostatic force is released from between the first and second beams, the second beam moves toward the third beam thereby releasing the first and second beams of an electric coupling.

摘要： A switch that is capable of responding at a high rate at a lower DC potential while providing high isolation. In this switch, a microstructure group, having microstructures, is used. By slightly moving the microstructures a small amount the group, as a whole, achieves a large amount of movement. Also, by this configuration, it is possible to decrease a DC potential to apply to control electrodes of the microstructures. As a result, a high isolation switch capable of operating at a high rate at a lower DC potential is realized.

摘要： A compact high-performance mechanical vibration filter which deals with high frequency band signals. Microcolumn beams as minute mechanical vibrators are used to increase a mechanical resonance frequency. The plural microcolumn beams are arranged in an array and a common detection electrode surrounds each microcolumn beam with prescribed gaps between them, thereby preventing an output signal from becoming weak. When some of the mechanical vibrators are restrained from vibrating, it is possible to monitor and remove a noise component generated in the output signal by direct electromagnetic coupling of an input signal.

摘要： A switch for switching over a propagation path of external signal by contacting or non-contacting a movable member to or from an electrode. The switch comprises an input port for inputting an external signal, a movable member connected to the input port, a first electrode for propagating the external signal, a first control power supply connected to the first electrode and for generating a control signal, a second electrode for blocking the external signal, and a second control power supply connected to the second electrode and for generating a control signal. The first control power supply provides a control signal to the first electrode. The movable member is displaced by a driving force generated based on a potential difference between the movable member and first electrode and a potential difference between the movable member and second electrode, thereby being contacted to the first or second electrode.

摘要： An object is to provide an electromechanical filter which can define a vibration mode so that a vibrator can be excited only in a desired vibration mode, that is, a filter which can suppress any vibration mode other than a desired vibration mode. The electromechanical filter includes a first member for inputting a signal, a second member disposed at a predetermined distance from the first member so as to surround the first member and to be excited due to an electrostatic force caused by the signal input from the first member, and a third member disposed at a predetermined distance from the second member so as to surround the second member and to detect vibration of the second member. The second member is designed to receive an attractive force from the first member and the third member so as to be bound and regulated as to a vibration direction.
