  • Patent number: 10811860
    Abstract: A wire harness includes electric wires, a curvature restricting member and an exterior member. The curvature restricting member includes a strip-like connecting portion and a plurality of pieces and is capable of being curved in orientation that the connecting portion is arranged inside and the pieces are arranged outside. In an inverse orientation, curvature of the curvature restricting member is limited by adjacent pieces abutted onto each other. The curvature restricting member is oriented such that a width direction of the connecting portion is a vertical direction and the connecting portion is positioned outside in a vehicle width direction with respect to the pieces when a sliding door is fully-closed. The connecting portion includes a portion with high flexibility and a portion with low flexibility, and a portion in vicinity of the sliding door has higher flexibility than a portion at a first end side of the curvature restricting member.

  • Patent number: 8559201
    Abstract: A grid-connected inverter includes first and second power conversion circuits, a contactor and a control circuit. The first conversion circuit converts a first DC voltage to a second DC voltage. The second conversion circuit converts the second DC voltage to an AC voltage. The contactor connects an output side of the second conversion circuit to a power system. The control circuit includes a decision circuit and controls start and stop operations of the conversion circuits, and opening and closing of the contactor. The decision circuit decides whether a condition of the contactor is abnormal by detecting, after the control circuit controls the contactor to be open, whether or not a value of the second DC voltage is less than a threshold value, and if the value of the second DC voltage is detected to be not less than the threshold value, decides that the condition of the contactor is abnormal.
