    摘要： A microswitch is provided with a movable electrode contact component including a bending displacement component having a cantilever shape, a piezoelectric/electrostrictive element having a piezoelectric/electrostrictor and a voltage application electrode layers, and a substrate joined to a support portion of the movable electrode contact component and having a fixed electrode disposed on the surface thereof, wherein the piezoelectric/electrostrictive element is driven to displace the movable electrode, so that the movable electrode and the fixed electrode can be brought into a state of being electrically connected to each other or disconnected from each other. At least a thin plate of the bending displacement component is made of a ceramic material, and the thin plate, the piezoelectric/electrostrictor, and the voltage application electrode layers are integrated by firing. The microswitch can efficiently switch high-frequency signals at low power consumption and has excellent responsiveness, excellent durability, and high reliability of long term driving.

    摘要： A first electrode and a second electrode are provided in separation on a main surface of a substrate made of a ferroelectric single crystal. A first voltage is applied between the first electrode and the second electrode, for example, on condition that the first electrode is positive and the second electrode is negative, to generate and grow a first polarization-inverted portion toward the second electrode from the first electrode. Then, the distance between the first electrode and the second electrode is changed, and a second voltage is applied between the first electrode and the second electrode on the same condition, to generate and grow a second polarization-inverted portion, in a different area from that of the polarization-inverted portion, toward the second electrode from the first electrode.

    摘要： According to the invention, a film of optoelectric single crystal may be formed on a substrate made of optoelectric single crystal by a liquid phase epitaxial process. The process comprises the steps of producing a melt of a solute and a melting medium, a solid phase and a liquid phase coexisting in the melt; then cooling the liquid phase for producing super cooling state in the liquid phase; and contacting the substrate to the liquid phase to form the film on the substrate by an epitaxial growing process. The film may be produced on the substrate, the film having a half value width of an X-ray rocking curve not more than that of the substrate.
