    Abstract: The balloon catheter of the present invention is provided with a balloon base at a front end of a tubular catheter body having a predetermined length. The balloon base includes a cylindrical base having a larger diameter than an outer diameter of the catheter body, and a lumen having substantially the same diameter as the outer diameter of the catheter body is formed on the base over an entire length with both ends opened. A central axis of the lumen is inclined at a predetermined angle with respect to a central axis of the base concentric with a central axis of the catheter body, and an outer peripheral surface is formed in parallel with the central axis of the base. The balloon is provided on the outer peripheral surface of the parallel base to obliquely inflate with respect to the central axis of the catheter body during inflation.

  • Patent number: 10304616
    Abstract: It includes an electricity receiving coil unit having an electricity receiving coil that generates heats due to electrical conduction thererof, an electric component storage box having a rectifier, and a harness electrically connecting the electricity receiving coil unit and the electric component storage box with each other. Part of the harness is routed in a vicinity of a front end of an upper face of the electricity receiving coil unit. Flows are made turbulent when traveling air hits the harness, and thereby airflows behind the harness turn into turbulence. Even if affixes such as mud fixate on the upper face of the electricity receiving coil unit, the affixes are removed by the turbulence.

  • Publication number: 20180351655
    Abstract: An output apparatus outputs an acoustic wave set with a specific frequency indicating identification information to a terminal apparatus that is to acquire the identification information from the acoustic wave. The output apparatus includes circuitry. The circuitry adjusts the specific frequency of the acoustic wave to another frequency by applying a predetermined frequency to the specific frequency, depending on a moving direction of a terminal apparatus that is to be notified of the identification information. The circuitry generates the acoustic wave of the another frequency. The circuitry outputs the generated acoustic wave of the another frequency.

  • Patent number: 10144300
    Abstract: A power receiving portion is installed in a middle in a vehicle width direction at a front portion on a lower surface of a floor panel close to steered front wheels. Therefore, the power receiving portion can be accurately aligned with a power supply portion on the road surface side so as to face each other with a sense of steering in such a manner as to align the center of a vehicle with the power supply portion when the vehicle advances to a predetermined stop position in a parking space. Moreover, a high-current system wire harness for transmitting electric power from a battery located on the lower surface of the floor panel to a motor unit in a front compartment passes above the power receiving portion so as to improve the safety of the wire harness.

  • Patent number: 9827864
    Abstract: A power reception-side coil is mounted on the bottom surface of a vehicle body and contactlessly receives power transmitted from a power feeding-side coil disposed on the ground. The power reception-side coil is of a solenoid type such that an electric wire is wound with the vehicle longitudinal direction as a coil axis. A shield member that is a plate-shaped magnetic shield is disposed between the bottom surface of the vehicle body and the power reception-side coil. The shield member has a forward-inclined surface serving as a first wall part protruding downward of the vehicle, the forward-inclined surface being raised and provided at the vehicle front side in a direction of the coil axis with respect to the power reception-side coil.
