  • Patent number: 7942628
    Abstract: A first compression stage and a second compression stage being arranged at positions adjacent to each other. The first centrifugal impeller and the second centrifugal impeller are arranged in such an orientation that back sides of the first centrifugal impeller and the second centrifugal impeller face to each other. A connection flow path is formed in the first housing and the second housing for introducing the compressed fluid from the first compression stage into the second compression stage.

  • Publication number: 20110004780
    Abstract: There is provided a server system that collects memory information at the time of occurrence of a failure if a failure occurs in the operating system so as to enable failure analysis. Stall monitoring of a firmware is performed by hardware and, if a stall is detected, a reset is performed. A memory has a memory area used by a boot loader of the firmware and a memory area used by another part of the firmware. It is determined based on a reset factor retained in a device whether the reset is a normal reset or a reset associated with the stall detection. In the case where the reset is a reset associated with the stall detection, information of the memory area of the memory used by the another part of the firmware at the time of occurrence of the stall is collected.

  • Publication number: 20100102616
    Abstract: Provided are a back pad having comfortable riding feeling and an excellent supporting performance for an occupant even if its thickness is reduced, and a seat for a vehicle having the back pad. A back pad (1) comprises a lumber part (2), a back support part (3) on the upper side of the lumber part, and side parts (4, 4) disposed on both the left and right sides of the lumber part (2) and the back support part (3). The back pad (1) is made of polyurethane foam. Since the hysteretic loss of the back support part (3) is larger than that of the lumber part (2), the vibration absorbing performance of the lumber part (2) may be excellent. The hardness of the lumber part (2) is higher than that of the back support part (3) whereby the performance of supporting the lumber of the occupant may be excellent.

  • Patent number: 7689728
    Abstract: There is provided a method for describing an ACPI machine language table used in a computer system having a multibridge PCI structure, which enables an OS to support hot plugs for PCI devices subordinate to a PCI multibridge. Upon receiving a call requesting a resource information method for a PCI device from an ACPI driver on an OS, a PCI configuration access is made to a subordinate bridge in a PCI device side, so that the ACPI machine language table supplied from a BIOS returns resource information of the PCI device. A PCI configuration access is made to a superordinate bridge in a PCI system bus side, to obtain resource information of the subordinate bridge. The resource information of the subordinate bridge is obtained from the superordinate bridge, and secondary resource information is obtained from a PCI configuration space of the subordinate bridge.
