    摘要: A structure with superior shock resistance is proposed for a parasol-type acceleration sensor. The acceleration sensor comprises a support portion the lower end of which is fixed to a substrate; a beam portion on which a detection element for applying changes to an output signal in correspondence with strain caused by acceleration acting on the detection element is formed, one end of the beam portion being connected to the top part of the support portion; a suspended weight connected to the other end of the beam portion; and a stopper substrate with a window portion through which, in order to guide an output signal of the detection element via a pad that is formed on the upper end face of the support portion, a conductor lead that is connected to the pad passes. Overswing of the weight is limited by means of the stopper substrate.

    摘要: Ladles used for vacuum refining processes, for example a VOD process, are provided with covers to cover openings of ladles. The covers generally consist of refractories, which are required to have excellent resistance to thermal spalling due to heat cycles and not inhibit decarbonization during refining processes of molten steel. The ladle cover comprises a refractory having a carbon content 5 wt % or more. Preferably, a refractory has a carbon content 5 wt % or more is used for a central section of the ladle cover, and a refractory having a carbon content less than 5 wt % is used for peripheral sections of the ladle cover.

    摘要: A piezoelectric resonator includes a base plate and a strip-type, energy trapping piezoelectric resonator chip mounted on the base plate. The piezoelectric resonator chip includes a piezoelectric chip plate and a pair of electrode patterns formed on the opposed main surfaces of the piezoelectric chip plate. One main surface of the piezoelectric chip plate faces the base plate and is parallel therewith, and a conductive layer is formed on each end of the main surface facing the base plate. The thickness of the conductive layer is greater than that of the electrode pattern so that the electrode pattern is separated from the base plate. The conductive layer is directly mounted onto a conductive portion of the base plate, so as to electrically connect the electrode pattern and the conductive portion of the base plate.
