  • Coaxial connector plug and manufacturing method thereof
    Patent number: 8678836
    Abstract: An outer conductor portion includes an outer conductor and a pair of outer terminals. The outer conductor is formed into a substantially cylindrical shape extending in the z-axis direction. The outer terminals are drawn toward the positive z-axis direction side of the outer conductor. In a plan view in the z-axis direction, the outer terminals are each bent in a direction outwardly from the outer conductor, and face each other across the outer conductor. An insulator has two sides, an upper surface in contact with a positive z-axis direction-side end portion of the outer conductor, and a lower surface in contact with the outer terminals at the sides, and thereby is nipped by the outer conductor portion in the z-axis direction. A central conductor is attached to the insulator, and is provided in a region surrounded by the outer conductor.

  • Package structure of a piezoelectric device mounting and supporting a piezoelectric vibration element
    Patent number: 8558435
    Abstract: A piezoelectric device has a piezoelectric vibration element mounted in a package wherein the piezoelectric vibration element comprises two stick-like vibration legs; a central leg provided between the two vibration legs; a coupling portion that couples one end of each of the two vibration legs and one end of the central leg; and a protrusion portion that is coupled to another end of the central leg, has a predetermined angle, neither 0 nor 180 degrees, to the length direction of the central leg, and extends into a direction not interfering with the driving legs. In making the piezoelectric device smaller and thinner, this configuration avoids interference between a support point on the central leg, provided for supporting the vibration element, and conductive electrodes, improves insulation between the conductive electrodes, and reduces the generation of short-circuits between the conductive electrodes.

  • TURBINE VANE OF STEAM TURBINE AND STEAM TURBINE
    Publication number: 20130243587
    Abstract: The invention includes vane members that have a space formed therein and a plate spring member that is disposed inside the space of the vane members and elastically contacts inner surfaces of the vane members. The plate spring member includes a positioning portion, an elastic contact portion, and a connection portion. The elastic contact portion is divided into plural numbers in the length direction of the vane members. As a result, in the invention, the elastic contact portion elastically contacts the inner surfaces of the vane members without any partial contact throughout the entire surface thereof. Accordingly, the elastic contact area between the elastic contact portion and the inner surfaces of the vane members is widened, so that self-excited vibration generated in a turbine vane may be reliably suppressed.
