  • Patent number: 7728500
    Abstract: In an electrodeless discharge lamp suitable for use at a place with unfavorable environmental conditions or at a place where lamp replacement is difficult, the replacement of a lamp unit is facilitated and the lamp unit is prevented from falling off from a power coupler unit even if there is component deterioration caused by long-term use. A metallic elastic member is provided near a position on a metallic heat conduction member of the power coupler unit that is farthest from an electromagnetic field generating portion. In addition to an ordinary coupling structure between the power coupler unit and a coupling member, the elastic member is engaged with the coupling member of the lamp unit. When the lamp unit is mounted on or removed from the power coupler unit, a bulb of the lamp unit is turned relative to the power coupler unit about the axis and moved forward/backward in the direction of the axis.

    Abstract: The present invention provides a storage unit system that can be connected to a plurality of different kinds of networks and a controlling method for a system LU of a storage device control unit required in such a storage unit system. In the storage unit system, to an LDEV of a storage device, it is possible to set a system LU for storing control information in the storage unit system itself and a user LU for writing write data sent from a host device, while a management terminal specifies a system LU or a user LU to set a path definition to the LDEV and a CHN inhibits an access to the system LU from the host device in accordance with distinction specified by the management terminal. Furthermore, a path of the system LU is automatically defined to a backup LU, so that the control information stored in the system LU is backed up to the backup LU.

  • Patent number: 7478267
    Abstract: The access control device comprises a first interface (IF) which receives access requests from a host device, and a second IF which respectively accesses one or a plurality of access destination candidates in an external device. The second IF attempts to access a particular access destination candidate if the first IF has received an access request, and outputs a judgment result indicating that a recovery has been performed if it is determined that a recovery has been performed after the access attempt has failed. The first IF detects whether there has been a recovery in the access path to the particular access destination candidate by referring to the judgment result output by the second IF.
