20100209793FUEL CELL SYSTEM AND METHOD FOR CONTROLLING THE SAME - A fuel cell system includes a replacing unit for replacing a gas remaining in the anode of the fuel cell with the anode gas supplied anew by the anode gas supply unit when starting up the fuel cell. The amount of the anode gas is set to be lower, if the operation condition determining unit determines that the last operation was performed in a low-temperature and short-time operation mode. The operation condition determining unit sets the amount of the anode gas so that the gas remaining in the anode can be replaced with the anode gas with an entire anode capacity if the anode was been scavenged while no electro-chemical reaction was progressing in the fuel cell. The present invention can set the amount of anode gas appropriately when starting up the fuel cell.08-19-2010

20080277997Vehicle wheel - A vehicle wheel in which an additional air chamber member in a tire air chamber is fixed on an outer circumferential surface of a well portion, which includes: a first vertical wall surface rising outward in a radial direction from the outer circumferential surface of the well portion and extending in a circumferential direction of the outer circumferential surface; and a second vertical wall surface formed in the well portion facing the first vertical wall surface, wherein the additional air chamber member comprises an additional air chamber formed therein and a communication hole communicating between the additional air chamber and the tire air chamber; and wherein the additional air chamber member is fitted between the first vertical wall surface and the second vertical wall surface, and both end portions of the additional air chamber member in a width direction of the vehicle wheel are secured between the first vertical wall surface and the second vertical wall surface.11-13-2008
20090072611Vehicle wheel with pressure sensor - A wheel body includes a wheel body including a disk and a rim fixed to an outer circumference of the disk for supporting a tire for the vehicle; an air pressure sensor unit for detecting a pressure in an air chamber in the tire with transmitter; a sub air chamber member on the rim, having a for reducing a magnitude of a resonance sound generated by an air column defined by the air chamber defined by the rim and the tire. The air pressure sensor unit and the sub air chamber member are disposed in a circumferential direction of the wheel so as to cancel out one unbalance mass distribution of the vehicle wheel in the circumferential direction of the wheel caused by disposing the air pressure sensor by another unbalance mass distribution of the wheel in the circumferential direction caused by disposing sub air chamber member.03-19-2009
20090108666Vehicle wheel - A sub air chamber provided around outer circumferential surface of a well of a rim of a vehicle wheel includes an upper plate and a lower plate connected at edges thereof which are fitted into channels in first and second vertical wall surfaces formed on the rim. At least one of the upper plate and the bottom plate has orthogonally and diagonally aligned beads to vertical walls, extending in a circumferential direction of the wheel, supporting the sub air chamber, connecting parts locally connecting the upper plate and the bottom plate. The sub air chamber has a protruding part for communicating the sub air chamber with the tire air chamber and serves as a stopper of the sub air chamber.04-30-2009
20100090520Vehicle wheel - A vehicle wheel which includes an additional air chamber member forming an additional air chamber in a tire air chamber. The additional air chamber member is fixed on an outer circumferential surface of a well portion of a rim. The additional air chamber member is provided with a communication hole communicating between the additional air chamber and the tire air chamber. The communication hole is disposed at a position shifted from a discharge port of an air valve for supplying air in the tire air chamber in a wheel circumferential direction and opened to the tire air chamber.04-15-2010
20100096909VEHICLE WHEEL - A vehicle wheel includes: a disk and a rim having a well portion and fixed to the disk for supporting a tire for the vehicle; and an additional air chamber member secured to an outer circumferential surface of the well portion in a tire air chamber defined between the rim and the tire. The additional air chamber includes a communication pipe with a communication through hole therein for communication between the additional air chamber and the tire air chamber. The additional air chamber has a peak in a radial direction of the vehicle wheel. A radius D04-22-2010
