    摘要: Disclosed is a vacuum circuit breaker including a small-sized electrode structure capable of reducing deformation with age thereby enhancing the reliability and a vacuum bulb and a vacuum bulb electrode used for the breaker. In the vacuum circuit breaker, each of a fixed electrode and a movable side electrode includes an arc electrode made from particles of a refractory metal material, a high conductive metal material and a low melting point metal; an electrode supporting portion, made from the high conductive metal material, for supporting the arc electrode; a back conductor having a diameter smaller than the electrode supporting portion; and an external side connecting portion having a diameter larger than that of the back conductor. The arc electrode is integrated with the electrode supporting portion, back conductor, and external side connecting portion by the high conductive metal material, preferably, by melting of the highly conductive metal material.

    摘要: A piezoelectric device comprises: a piezoelectric resonator element having a base, a plurality of oscillating arms paralleled each other and extended from the base, a plurality of supporting arms extended from the base and in parallel with the side surface of each of the plurality of oscillating arms so as to sandwich the plurality of oscillating arms, a groove formed in at least one of a front surface and a back surface of each of the plurality of oscillating arms and an end weight layer formed in at least one of the front surface and the back surface near to an end portion of each of the plurality of oscillating arms; a package storing the piezoelectric resonator element within a containable recess and being air-tightly sealed by a lid; a bottom surface recess rimmed in the bottom surface of the containable recess; and a connecting pad formed as a protrusion in an region that is connected with the plurality of supporting arms in the bottom surface of the containable recess. A part of the plurality of supporting arms is connected to the connecting pad via a joint portion. The bottom surface recess includes an edge in a region of the bottom surface of the containable recess opposing a part of the plurality of oscillating arms between the groove and the end weight layer, and the edge rims the bottom surface recess so as to allocate a part of the bottom surface of the containable recess opposing the end weight layer inside of the edge.
