  • Patent number: 8320154
    Abstract: A micro-switching element provided with a first electrode 4 containing an ionic conductor and a second electrode 5 composed of an electric conductor, wherein the first electrode 4 and the second electrode 5 are physically and electrically connected to each other through deposition of a metal ion from the ionic conductor, and wherein a photoresponsive film 9 that receives light to generate a carrier is disposed between the first electrode 4 and the second electrode 5 to fill up the space between the electrodes. Accordingly, a micro-switching element is provided of which the characteristic fluctuation is small and which hardly produces a problem of operation failure.

  • Patent number: 8291162
    Abstract: One code (a compressed redundant code) is created based on a plurality of first redundant codes, each created on the basis of a plurality of data units, and this compressed redundant code is written to a nonvolatile storage area. This compressed redundant code is used to restore either a data element constituting a multiple-failure data, or a first redundant code corresponding to the multiple-failure data, which is stored in an unreadable sub-storage area of a partially failed storage device, and to restore the data element constituting the multiple-failure data which is stored in a sub-storage area of a completely failed storage device, based on the restored either data element or first redundant code, and either another data element constituting the multiple-failure data or the first redundant code corresponding to the multiple-failure data.

  • Patent number: 7875352
    Abstract: A stabilized inorganic nanoparticle which is stabilized by bonding protective ligands to a surface of an inorganic nanoparticle, wherein one part of binding sites on the surface of the inorganic nanoparticle are bonded to the protective ligand, the other part of the binding sites remain as a free site not bonded to the protective ligand, and satisfies the condition that the amount of the protective ligand bonded to the inorganic nanoparticle is a critical amount or the condition that the form of modifying the surface of the inorganic nanoparticle by the protective ligand is a critical modification form. According to the present invention, there is provided a stabilized inorganic nanoparticle that is stabilized by a protective ligand and can be rapidly functionalized with ease by bonding a functional ligand thereto.

  • Patent number: 7865665
    Abstract: A disk array system having first and second housings and a controller for controlling the first and second housings. Fiber channel hard disk drives are received in the first housing, and serial ATA hard disk drives are received in the second housing. When reading data stored in a serial ATA hard disk drive in the second housing, the controller reads a plurality of pieces of data including the data to be read and parity data for the plurality of pieces of data from all the hard disk drives of an RAID group to which the hard disk drive storing the data to be read belongs. Thus, the controller examines whether the plurality of pieces of data including the data to be read are written in the hard disk drives with erroneous contents or not.

  • Patent number: 7181570
    Abstract: A diskarray system has a diskarray controller and a plurality of disk devices. Each of the disk devices has a media, a head, and a head position controller. The diskarray controller performs online data check operation, and stops the online data check operation over the disk device at first predetermined timing. After stopping the online data check operation, the diskarray controller issues an unload enable command to the disk device so as to move the head to a position different from positions at which the head reads or writes data from or to the media. The head position controller of the disk device moves the position of the head on the basis of the received unload enable command.
