According to one embodiment, a circuit element includes a silicon substrate, a lower electrode, a dielectric film, and an upper electrode. The lower electrode is formed on a major surface of the silicon substrate by a doping process. The dielectric film is formed on the lower electrode. The upper electrode is formed on the dielectric film. The upper electrode includes a slit.

Circuit element

A displacement conversion mechanism of an embodiment is a displacement conversion mechanism which is provided with a base, a displacement element which is in contact with the base and is displaced in a first direction, a first displacement portion which is in contact with the displacement element and can be displaced in the first direction, a second displacement portion which connects to an end of the first displacement portion at a first connection portion, and connects to the base at a second connection portion, and a third displacement portion which connects to the other end of the first displacement portion, connects to an end portion of the second displacement portion at a fourth connection portion, and can be displaced in a second direction intersecting with the first direction.

Displacement conversion mechanism and tunable filter device

A thermal insulation waveguide between a high-temperature unit and a low-temperature unit in a vacuum, chamber of an embodiment, the thermal insulation waveguide includes, a first substrate including a first line in the high-temperature unit, a second substrate including a second line in the low temperature unit, and a thermal insulation element connecting the substrates, and including a third line including an inductance component and connecting the first and second lines. The first substrate includes a first capacitor unit connected with the first line. The second substrate includes a second capacitor unit connected with the second line.

Thermal insulation waveguide and wireless communication device

According to an embodiment, a control apparatus includes a shaper and a compensator. The shaper receives a first target value in position control of a controlled object and generates a second target value which changes substantially rampwise over a time equal to or shorter than a period corresponding to one of resonance frequencies of the controlled object until the second target value becomes equal the first target value. The compensator compensates for a control signal, used for controlling the controlled object, based on the second target value.

Control apparatus and tunable filter apparatus

According to an embodiment, a filter characteristic tuning apparatus includes a characteristic tuning member, an elastic member, a first movable member, a second movable member, and a driving mechanism. The elastic member comes in contact with a characteristic tuning member by deformation, and separates from the characteristic tuning member by a restoring force. The first movable member deforms the elastic member in a closing operation. The driving mechanism displaces a second movable member such that a projection opens/closes the first movable member. The characteristic tuning member changes a gap between the characteristic tuning member and the resonator by a linear driving force obtained by converting the transmitted rotary driving force.
