  • Load simulator
    Patent number: 9425024
    Abstract: A load simulator includes a passive element, two electrode plates that are connected to the passive element, and a bias applier. The bias applier is a coil spring, for example, and is provided between the two electrode plates. The bias applier biases at least one of the two electrode plates in a predetermined direction. The two electrode plates are disposed so as to be substantially parallel with each other, for example, and the bias applier biases the two electrode plates in the direction of separation from each other.
    Type: Grant

  • High frequency detection device and coaxial cable including the same
    Patent number: 8937480
    Abstract: The present invention provides a high frequency detection device that detects a high frequency voltage signal according to a high frequency voltage generated in a power transmission body. The high frequency detection device includes a substrate and a capacitance conductor fixed to the substrate. The capacitance conductor includes a penetration portion and a capacitor electrode. In the penetration portion, the power transmission body is disposed so as to extend along the penetration portion in a state in which the axial direction of the power transmission body and the substrate are substantially orthogonal. The capacitor electrode is provided to be opposed to the power transmission body.
