Abstract: A partial discharge measurement device according to the present invention includes a frequency separation unit for separating a partial discharge signal which occurs in an apparatus under diagnosis and is detected by a sensor into the partial discharge signal and a main circuit voltage phase signal, an arithmetic device which receives the partial discharge signal and the main circuit voltage phase signal separated by the frequency separation unit and calculates a partial discharge signal synchronized with a main circuit voltage based on the partial discharge signal and the main circuit voltage phase signal, a power supply device for extracting a voltage obtained by dividing the main circuit voltage and supplying a power supply voltage to the arithmetic device, and a control unit for issuing an instruction for powering on or off at least the arithmetic device to the power supply device.

Abstract: Multiple protecting devices, such as an air bag and an air bag jacket, are controlled and operated in accordance with the shape and size of an impact. A normal collision determining section causes the air bag and/or the air bag jacket to operate in accordance with the magnitude and direction of a collision based on outputs of G sensors. When a collision predicting section predicts a collision on the basis of other vehicle information obtained by a vehicle-to-vehicle communication device and own-vehicle information, it causes a stand-by collision determining section to start instead of the normal collision determining section. The stand-by collision determining section determines a collision mode in advance and sets a threshold value for determining the outputs of the G sensors to a value different from a value used in the determination of the normal collision determining section so as to permit quick determination of a collision.

Abstract: A tube which includes: a tube body portion through which a fluid flows; a protector portion having an interior hollow space in which the tube body portion is provided, and an exterior wall defining the interior hollow space and having a flat outer surface; and a supporting portion supporting the tube body portion inside the hollow space in a position spaced from an inner surface of the hollow space. The supporting portion extends from the exterior wall of the protector portion in a direction substantially perpendicular to the flat outer surface of the exterior wall and across the hollow space to support the tube body portion at a middle portion thereof.

Abstract: A washer nozzle is provided with a pair of clicks protruding in the opposite directions for engaging to a vehicle body and a wedge-shaped projection overhanging in the direction in the intersecting at right angles to the protruding direction of the clicks for being pressed against the vehicle body to a cyclindrical part forming a part of the washer nozzle, and possible to be fixed on the vehicle body securely because it is restricted in the both directions intersecting perpendicularly each other.
