  • Patent number: 10792474
    Abstract: A guidewire includes a core shaft, a coil body disposed around an outer periphery of the core shaft, and a resin layer. The resin layer includes a proximal end part disposed around an outer periphery of the coil body; a distal end part located between the core shaft and the coil body distal to the proximal end part and having an outer diameter that is smaller than an outer diameter of the proximal end part; and a tapered part located between the proximal end part and the distal end part and having an outer diameter that decreases in the distal direction. The distal end part of the coil body is not covered with the resin layer.

  • Patent number: 9685682
    Abstract: A secondary battery module 1 of the present invention stores cell blocks 40 in a module case 2, and cools battery cells 101 in the cell blocks 40 by circulating coolant to the inside of the cell blocks by introduction of the coolant into the module case 2. The secondary battery module has a structure of communicating coolant circulation ports 22 that open to a case wall section 21 of the module case 2 and coolant circulation ports 62a that open to the cell blocks 40 with each other by a communication member 71, and passing wiring through a space region 80 formed outside the communication member 71 and between the case wall section 21 and the cell blocks 40. Thus, wiring can be executed without interfering flow of the coolant, and the total secondary battery module 1 can be miniaturized.
