    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.

    摘要: A cathode ray tube display device including unnecessary radiating magnetic field reducer which improves the ability to reduce an unnecessary radiating magnetic field, especially, generated by a vertical deflection coil. A pair of coil is disposed in opposing relationship on the opposite sides of the ferrite core along an X-axis or in the horizontal direction of the deflection yoke so as to be in contact with an open side end of the ferrite core. Each coil has a shape curved with a predetermined radius of curvature conforming to the shape of the outer peripheral surface of the ferrite core. The ferrite core acts as a magnetic material for the coils which reduces the unnecessary radiating magnetic fields to increase the coil inductances to thereby produce a large extremely low frequency magnetic field (ELMF) reducing effect.
