  • Patent number: 7743208
    Abstract: A file memory stores data corresponding to identifiers of an allocated area in an identifier space. A first memory stores a basis position of the allocated area in the identifier space. A second memory stores a weight of the storage apparatus as a performance degree. A first decision unit decides a space width to divisionally allocate the identifier space with another storage apparatus by using the weight and a weight of another storage apparatus. Another storage apparatus allocates a neighboring area of the allocated area in the identifier space. A second decision unit decides the allocated area of an area between the basis position and a basis position of the neighboring area in the identifier space by using the space width.

  • Patent number: 7713056
    Abstract: A catalytic combustor is configured to accelerate the combustion processing of anode off gas in the combustor to reduce the amount of unburned hydrogen discharged to the outside of the combustor. Anode off gas and cathode off gas discharged from the fuel cell are fed into the catalytic combustor and combusted with a catalyst. Ventilation air is supplied from inside of the fuel cell is also supplied to the catalytic combustor. A portion of the catalytic combustor located upstream of the catalyst inside is divided into an upper flow path and a lower flow path by a partitioning plate and a gas flow passage is provided upstream of the upper and lower flow paths. The cathode off gas is supplied to the gas flow passage.

  • Publication number: 20080155551
    Abstract: In an apparatus for resource management, a resource bidding unit calculates a bid price indicating a virtual price of a resource for each of application programs to consume or supply within a predetermined unit-time, and makes a bidding by inputting the calculated bid price. A bidding management unit allocates a resource per unit-time to each of the application programs based on the bid price input by the resource bidding unit. Moreover, the resource bidding unit determines a state of an application program whether active or inactive, and calculates the bid price to allocate the resource preferentially to an active application program rather than an inactive application program.

  • Publication number: 20080118879
    Abstract: A controller determines whether a rate of temperature rise on an upstream side of a catalyst portion is at a determination criterion value or higher, and, when the rate of temperature rise on the upstream side of the catalyst portion is at the determination criterion value or higher, the controller determines that a combustor is in an abnormal combustion state. Therefore, an abnormal combustion state of the combustor can be detected before temperature of the combustor becomes high.
