    摘要: The first movable electrode is flat, but the second movable electrode is deformed into a convex shape. A dielectric layer is placed on the facing surface of the second movable electrode. By adjusting a voltage to be applied between the first movable electrode and the second movable electrode, an arbitrary distance is secured between the two electrodes by the electrostatic attractive force generated between the two electrodes, and a desired electrostatic capacitance is obtained. When the distance between the two electrodes is shortened, first, at the center, a part of the first movable electrode and a part of the second movable electrode come into contact with each other with the dielectric layer between them. Then, the first movable electrode and the dielectric layer (second movable electrode) come into contact with each other successively from the contact part towards the periphery side, and the contact area gradually increases.

    摘要: A microswitching element includes a base substrate, a fixing portion attached to the base substrate, and a movable portion including a fixed end fixed to the fixing portion. The movable portion is surrounded by the fixing portion via a slit having a pair of closed ends. The movable portion includes a first surface and a second surface. The first surface faces the base substrate, and the second surface is opposite to the first surface. The microswitching element also includes a movable contact portion provided on the second surface of the movable portion, and a pair of fixed contact electrodes each including a contact surface facing the movable contact portion. The fixed contact electrodes are attached to the fixing portion.

    摘要: An electrical contact device (X1) includes a first contactor with contact portions (C1, C2) and a second contactor with contact portions (C3, C4). The device (X1) also includes an electrical circuit having a branch path (YA) provided by the contact portions (C1, C3) and a branch path (YB) provided by the contact portions (C2, C4). When closed, the branch path (YA) has a smaller resistance, and the branch path (YB) a greater resistance. In a closing operation, the first and second contactors approach each other. Then the contact portion (C1) and the contact portion (C3) contact with each other after the contact portion (C2) and the contact portion (C4) contact with each other. In an opening operation, the first and second contactors separate from each other. Then the contact portion (C1) and the contact portion (C3) separate after the contact portion (C2) and the contact portion (C4) separate.

    摘要: An electrical contacting device includes a plurality of current paths connected in parallel to each other, and a plurality of electrical contact points each having a first contact and a second contact that are mechanically opened and closed. Each current path is provided with a corresponding one of the contact points. For prevention of the occurrence of arc discharge at the contact points, each current path has its electrical characteristics adjusted in order not to allow the passage of the minimum discharge current.

    摘要: A film bulk acoustic resonator is fabricated in the following manner. First, a base layer is formed on an insulating substrate. Then, a resonator assembly is formed on the base layer. The resonator assembly includes a first electrode held in contact with the base layer, a second electrode, and a piezoelectric layer held between the first and the second electrodes. Then, a resist layer is formed to cover the resonator assembly and the base layer. Then, a through-hole is formed in the resist layer so that the base layer is exposed via the through-hole. Then, etchant is supplied via the through-hole to make a space in the base layer under the resonator assembly. Finally, the resist layer is removed.
