  • Publication number: 20110116893
    Abstract: An object of the present invention is to provide a connection structure for sheet-metal parts that permits two sheet-metal parts to be screwed to each other with good conductivity by a simple process in a simple structure, and an image forming apparatus provided with the connection structure. Disclosed is a connection structure for connecting a first sheet-metal part (31) to a second sheet-metal part (41) by placing the sheet-metal parts (31) and (41) such that their respective contact surfaces face to each other and by connecting the contact surfaces by a screw (50). A first pilot hole (32) that is smaller than the screw (50) is made in the first sheet-metal part (31), and a plurality of first small holes (33) that are smaller than the first pilot hole (32) are made in the first sheet-metal part (31), around the first pilot hole (32).

  • Patent number: 7891644
    Abstract: A air spring 10 is provided, where flex deformation of a shoulder portion in a dustcover due to the restorative force of a bellows portion during compression thereof is prevented, whereby deterioration of the life of the dustcover due to such deformation is prevented. With the air spring 10, a stopper 82 of a deformation-preventing cap 70 is arranged at the outer peripheral side of a shoulder portion 54 in a dustcover 50. At the time of compression deformation of a bellows portion 56, the stopper 82 comes into contact with the shoulder portion 54, and flex deformation of the shoulder portion 54 towards a linking tube 52 side is restricted. Due to this, the restorative force from the compression deformed bellows portion 56 via the shoulder portion 54 can be supported by the stopper 82 of the deformation-preventing cap 70.

  • Publication number: 20090313391
    Abstract: The disclosed is a computer system enabling a plurality of LPARs on a plurality of physical computers to share an SR-IOV device that requires an interface between a PF and a VF. In an environment where a PCI SR-IOV device is allocated to virtual machine monitors on a plurality of physical computers through an I/O switch, a PF is allocated to a first virtual machine monitor and a plurality of VFs is allocated to an LPAR on an optional virtual machine monitor. When a second virtual machine monitor detects an event that is generated from a VF to the PF, the second virtual machine monitor communicates the detected event to the first virtual machine monitor to which the PF is allocated, and allows the first virtual machine monitor to execute the PF event.

  • Patent number: 7538780
    Abstract: A drawing processing apparatus and method wherein scrolling display which provides no sense of incongruity is achieved in 3D display. 3D information is produced using information in a drawing object range extracted as a predetermined range on map data. The drawing object range of an object of the 3D drawing process is moved in response to a scrolling operation. While the drawing object range is moved, 3D image data are successively produced using the drawing object range at every point of time and outputted to implement 3D display on a display screen. Thereupon, the drawing object range to be used for the 3D drawing is moved such that individual portions in the drawing object range are moved by movement amounts determined with reference to a distance in a perpendicular direction at a reference position in the drawing object range.

  • Patent number: 7509475
    Abstract: A virtual machine control method and a virtual machine system are disclosed. In the case where a guest program can be operated in a plurality of address translation modes and the same guest virtual address is translated into different host real addresses in each address translation mode, the illegal access to a host real address by illegal address translation by double registration in the same page table is avoided, and the address translation mechanism is efficiently operated. A plurality of host page tables are prepared in the main storage, and one of the host page tables is selected with the change in address translation mode of the guest program. The bottom address of the selected host page table is set in the host page table register thereby to switch the host page table.
