  • Patent number: 9362563
    Abstract: The present invention provides a highly reliable energy storage device capable of preventing a reaction current from flowing in a carbon nanotube electrode by ionizing a catalyst metal or a substrate metal to cause the metal to flow out to an electrolytic solution. An energy storage device of the present invention includes: at least a pair of electrode bodies that are a cathode and an anode; and an electrolytic solution. At least one of the electrode bodies is configured such that a layer of carbon nanotubes is formed on an electric conductor. A coupling region where one ends of the carbon nanotubes are coupled to and electrically connected to the electric conductor and a non-coupling region where ends of the carbon nanotubes are not coupled to the electric conductor are formed on a surface of the electric conductor. The carbon nanotubes having one ends connected to the coupling region are toppled to cover a surface of the non-coupling region.

  • Patent number: 9301342
    Abstract: A heater wire is obtained by twisting together a plurality of heating element wires in which a rectangular wire is spirally wound around a core wire, and forming an insulating sheath on an outer peripheral surface of the twisted heating element wires. The current carrying capacity can be increased by increasing the number of the heating element wires and there is no need of increasing the cross-sectional area of each of the rectangular wires. Therefore, a reduction in the bending capacity due to an increase in the cross-sectional area of the rectangular wires can be avoided, and the bending capacity can be improved significantly.
