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.

The switching element includes a substrate, two supporting members fixed to the substrate, and a movable beam bridging between the supporting members. The beam includes a membrane, a movable contact electrode and a movable driving electrode, both disposed on the membrane. The switching element also includes a pair of stationary contact electrodes facing the movable contact electrode, and a stationary driving electrode cooperating with the movable driving electrode for generation of electrostatic force.

摘要： An angular velocity sensor is provided that includes a frame, an oscillator and torsion bars that connect the oscillator to the frame. The frame, the oscillator and the torsion bar are formed integral with each other by etching a material substrate in the thickness direction of the substrate. The oscillator, configured in the form of an H, includes a support, two first arms and two second arms. These arms extend from the support in an arm-extending direction perpendicular to the thickness direction of the substrate. The oscillator includes a mounting surface that is provided with a piezoelectric driver for generating in-plane oscillation of the oscillator, and with a piezoelectric detector for detecting out-of-plane oscillation of the oscillator.
