If a customer has picked up a product from a display shelf, a display device displays first sales promotion information. In an information providing system, if the customer has not been attracted to the product and has returned the product to the display shelf, the display device displays second sales promotion information, which is different from the first sales promotion information. By displaying the different pieces of sales promotion information using the display device provided near the product, it is possible to promote the product to the customer in two different ways, thereby stimulating the customer's desire to buy the product and reducing loss in opportunities to sell the product.

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.

The electromechanical element includes a first electrode formed on a substrate, a second electrode formed at a predetermined interval to the first electrode so that the interval is changed, and supporting portions for supporting the second electrode, wherein the supporting portions of the second electrode are able to be displaced.

Electromechanical element and electronic equipment using the same

An electromechanical filter of the present invention is an electromechanical switch formed on a substrate. The switch has a fixed electrode which is to become a signal transmission line, and a movable electrode formed in a levitating manner while being spaced from the fixed electrode with a gap therebetween. An insulating film is provided on the fixed electrode, and an actuator is formed around the movable electrode formed on a post section. Thereby, an electromechanical switch equipped with a movable electrode fixing mechanism which prevents occurrence of self-actuation, which has hitherto been difficult to realize, is materialized.

Electromechanical switch

The present invention provides an electromechanical switch enabled to achieve a high-speed switching response at a low driving voltage. An electromechanical switch body, which is an MEMS switch, has a first movable electrodeand a second movable electrode, both ends of each of which are respectively fixed to and laid on a first anchorand a second anchorformed on a silicon substrate, and also has a fixed electrodethat faces these movable electrodes. A first electromechanical switchenabled to be driven at a low voltage is constituted by the first movable electrode, which has a relatively weak spring force, and the fixed electrode. A second electromechanical switchenabled to be latched at a low voltage is constituted by the second movable electrode, which has a relatively strong spring force, and the fixed electrode. Consequently, the first movable electrodeis displaced at high speed at a low driving voltage, so that the first electromechanical switch is turned on at high speed. A restoring force causes the second movable electrodeto perform natural vibrations at high speed, so that the second electromechanical switch is turned off at high speed. The restored second movable electrodeis latched at a low driving voltage, so that the second electromechanical switch is turned on.

The outer wall detects an oscillation of the inner wall when a signal of a predetermined frequency is inputted from a connected signal input side electrode to the inner wall, so that this signal is outputted via a connected signal output side electrode.

An MEMS switch includes a substrate, a conductive beamformed on a surface of the substrate, and three-layer structure beams Band Bformed on the surface of the substrate and disposed to be opposed to the conductive beam. The MEMS switch is characterized in that: each of the three-layer structure beams includes a first conductive layer, a second conductive layerand a dielectric layersandwiched between the first conductive layer and the second conductive layer; the first conductive layer is opposed to the conductive beam; at least one of the conductive beamand the three-layer structure beams is displaced on a plane parallel to the substratedue to an electrostatic force so that the conductive beamand the first conductive layercan come into contact with each other; and a conductive path is formed between the conductive beamand the second conductive layerwhen the conductive beamand the first conductive layer are in contact with each other.

MEMS switch

A small-size electromechanical filter that can be highly integrated and can be tuned is provided. An electromechanical filter includes a conductor acting as a signal line (movable electrode)a magnetic field generating portionfor generating a magnetic field passing through the conductor, and a drive electrodefor changing the magnetic field passing through the signal line by displacing relative positions of the conductor and the magnetic field generating portion, whereby a tuning of a ferromagnetic resonance frequency, which is difficult to realize in the prior art, can be realized by changing the magnetic field passing through the signal line.

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.
