摘要： An electric contact device (X1) comprising a first contact having contact parts (C1, C2), a second contact having a contact part (C3) facing the contact part (C1) and a contact part (C4) facing the contact part (C2), and circuitry (Y1) where a branch (YA) including an electric contact (SA) consisting of the contact parts (C1, C3) and exhibiting a relatively low resistance under closed state of the electric contact (SA) and a branch (YB) including an electric contact (SB) consisting of the contact parts (C2, C4) and exhibiting a relatively high resistance under closed state of the electric contact (SB) are arranged in parallel. In the closing operation where the first and second contacts approach each other, the contact parts (C1, C3) abut against each other after the contact parts (C2, C4) abutted against each other. In the opening operation where the first and second contactors recede from each other, the contact parts (C2, C4) recede from each other after the contact parts (C1, C3) receded from each other.

摘要： A tuning fork type vibrational gyroscope, wherein a tuning fork type oscillator having two arms and a base is supported on a supporting substrate installed on a stem, and an oscillation limiting member comprising an annular rubber elastic body is installed so that it surrounds the base with its one face fixed to the stem, whereby though, when a vibration or impact is given externally, the tuning fork type oscillator is oscillated according to the vibration or impact, the amplitude of the tuning fork type oscillator is limited by the presence of an oscillating limiting member so as to prevent the tuning fork type oscillator from impacting against surrounding members such as the stem, and a gyro characteristic is not impaired and also there is no possibility that a gyro function is lost due to stop of driving vibration.

摘要： In an acoustic wave filter constituted by arranging resonators having resonance characteristics or antiresonance characteristics in a ladder form, the resonator on the parallel arm in the first stage on the input side has a large flowing-in current and its service life is shortened due to the heat generated from its thin-film wiring. In order to prevent the shortening of the service life of the resonator, bonding wires (33, 31) are bonded to connecting electrodes (130, 131) for connecting one end of each of comb-teeth-like electrodes constituting the resonator or bonded to lead-out conductor (130-1) extended in the longitudinal direction of the connecting electrodes at positions on both sides of the center line C1 of the comb-teeth-like electrodes. The wires (33 and 31) may be bonded on the center line C1, but it is preferable to bond the wires (33 and 31) symmetrically with respect to the center line C1. It is preferably that the lengths of the comb-teeth-like electrodes are larger than the widths of the electrodes.
