  • Patent number: 8464893
    Abstract: A pressure container has an inner shell with a pair of fittings and a reinforcement layer formed around the inner shell, and is configured so that a reinforcement member is attachable to the pair of fittings in a process of forming the reinforcement layer and a functional component which performs a predetermined function is also attachable to the fittings. This can allow the reinforcement member to prevent expanding deformation of the pressure container in production of the pressure container, and can ensure effective use of openings after removal of the reinforcement member.

  • Patent number: 8434507
    Abstract: A safety valve device has a safety valve body and is configured to open at a temperature of or over a preset reference temperature. The safety valve device also includes a gas flow path arranged to make a flow of hydrogen flowing out of a hydrogen tank via the safety valve body in a valve open position, and a discharge pipe configured to have a hydrogen discharge opening and arranged to discharge the hydrogen flowing through the gas flow path to the outside. The hydrogen discharge opening of the discharge pipe is formed to discharge the hydrogen in an oblique direction relative to a direction of an axial center of the gas flow path. The discharge pipe also has a groove formed to apply an input rotational force to the discharge pipe and thereby rotate the discharge pipe around the axial center of the gas flow path.

  • Publication number: 20100170906
    Abstract: A tank for storing gas is provided with a dye capsule layer including capsules containing dye or with an impact recording layer formed on the outer surface of the tank body. The impact recording layer has, for example, a hear-insulating material layer formed on the outer surface of the tank body, having a heat-insulating function, and capable of holding deformation, a dye capsule layer formed on the outer surface of the heat-insulating layer and including capsules containing dye, and a dye absorbing layer formed on the outer surface of the dye capsule layer and capable of absorbing dye. By an impact, the dye released from the dye capsule layer is absorbed into a dye absorbing layer of the tank. The dye exudes on the surface of the dye absorbing layer and spreads. The degree of impact given to the tank is estimated from the degree of spread of the dye or the degree of density of the dye.
