  • Patent number: 8718467
    Abstract: Terminals of upstream and downstream sides of an in-service line and a detour line are connected by optical couplers. An optical oscilloscope is connected to one optical coupler, and a chirped pulse light source is connected to the other optical coupler to thereby form dualized lines. The detour line includes an optical line length adjuster for compensating for the phase difference of optical transmission signals that occurs because of the optical line length difference with the in-service line. Pulse light in which an optical frequency is chirped is transmitted from the chirped pulse light source. The pulse light is branched by the second optical coupler, passes through the in-service line and the detour line, is multiplexed again by the first optical coupler, and is measured by the optical oscilloscope.

  • Publication number: 20130301189
    Abstract: An electrolytic capacitor according to the present invention employs a capacitor element wherein an anode foil having an anode internal terminal and a cathode foil having a cathode internal terminal are wound or laminated through a separator. The end of the anode foil faces with the cathode foil through the separator and the surface area of the cathode internal terminal is provided with an enlargement treatment, whereby the small area portion of the cathode foil that faces with the anode foil is eliminated, and the charge/discharge characteristics are thus improved.

  • Patent number: 8156827
    Abstract: An external force detection device includes a weight portion, a supporting portion, and a beam portion provided in an SOI substrate which includes an upper layer and a lower layer that are capable of being etched with a first etching gas and sandwich an intermediate layer that is capable of being etched with a second etching gas. The weight portion is displaced in accordance with an external force to cause the beam portion to deform. The upper layer in a gap portion between the weight portion and the supporting portion is etched. The lower layer in the gap portion and the lower layer below the beam portion are etched. The intermediate layer in the gap portion is then etched. The groove formed by etching the upper layer has a multidirectional two-dimensional shape.

  • Patent number: 8093853
    Abstract: A device-positioning pedestal capable of positioning devices of different sizes. The device-positioning pedestal comprises a plurality of guide members corresponding to the sides of the device and coming in contact with the sides of the device to position the device, at least one guide member includes a slide mechanism that supports the guide member so as to slide relative to the device-positioning pedestal member and a fixing mechanism that fixes the guide members at desired positions. The guide members are set to be adapted to the size of the device by the guide member-adjusting means separate from the device-positioning pedestal. The guide member-adjusting means adjust the position of the guide members based on the size of the device measured by device size-measuring means separate from the guide member-adjusting means or based on the data of data-recording means attached to the device-positioning pedestal.
