20100170906 | TANK - 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. | 07-08-2010 |
20100269956 | GAS SUPPLY STRUCTURE - A gas supply structure includes a nozzle having a gas supply passage, and a receptacle having an insertion hole into which the nozzle is inserted to achieve connection, wherein the receptacle is provided with a first O-ring that is provided in the vicinity of the insertion hole for the purpose of gas sealing, and a second O-ring that is provided further downstream the gas supply path than the first O-ring for the purpose of gas sealing, a portion of the second O-ring is bonded to a recessed section in the receptacle using a bonding material, and a foreign matter removal member is positioned closer to the insertion hole than the second O-ring. The foreign matter removal member is provided within the receptacle so as to partially protrude from an inner peripheral surface that extends from the insertion hole of the receptacle. | 10-28-2010 |
20100276024 | SAFETY VALVE DEVICE, VALVE APPARATUS, HIGH-PRESSURE GAS TANK, AND VEHICLE - A safety valve device has a safety valve body configured to include a valve mechanism opened 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 of the valve mechanism, 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. In a typical application of a high-pressure gas tank with such a safety valve device mounted on a vehicle, this arrangement of the safety valve device enables the discharge direction of the high-pressure gas that is discharged from the safety valve device to be readily adjusted. | 11-04-2010 |

20090032135 | Fuel Supply method and fuel supply device - In order to enable fuel to be sufficiently supplied to a mobile object without requiring a power source outside the mobile object, a compressor is driven by power supplied from a fuel cell vehicle, and hydrogen emitted to gas piping from a pressure accumulator is supplied to a high-pressure hydrogen tank of the fuel cell vehicle side, in a method for supplying the hydrogen as a fuel gas to the high-pressure hydrogen tank mounted on the fuel cell vehicle from the pressure accumulator of the hydrogen station. A power-supplying operation required for driving the compressor is performed by at least a secondary battery or a fuel cell. | 02-05-2009 |
20090050630 | Mobile Object Managing Device and Method - To improve the management quality of a fuel tank by managing a set of relevant information on the fuel tank and relevant information on a mobile object associated with each other and allowing a history of use of the fuel tank to be trackable, a mobile object with a fuel tank, has control means for storing the fuel tank relevant information stored in first storage means provided at the fuel tank, and the mobile object relevant information stored in second storage means provided at the mobile object in the first storage means and/or the second storage means in association with each other. The fuel tank relevant information includes at least one of information on the owner of the fuel tank, information on production of the fuel tank, information on an attribute of fuel to be filled, and information on the filling work, and the mobile object relevant information includes at least one of information on the owner of the mobile object, the serial number of the mobile object, and the registration number of the mobile object. | 02-26-2009 |
20090071965 | Pressure container and method of producing the same - 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. | 03-19-2009 |
20090186256 | RECEPTACLE - A receptacle including a structure for connecting a mobile object having a supply port with a fuel supply device connected to the supply port to supply the mobile object with fuel and external power is provided. The fuel supply device is provided with a first conductive portion containing the supply port when being connected, and supplying the mobile object with the fuel via a fuel supply channel formed therein, a second conductive portion provided on the outer peripheral side of the first conductive portion to supply the mobile object with the external power when being connected, an insulating portion electrically insulating the first conductive portion from the second conductive portion, and a ground line grounding the first conductive portion. | 07-23-2009 |
