20090252881 | METHOD OF SPRAY APPLICATION, AND SPRAY APPARATUS, FOR BENTONITE MATERIAL - The present invention provides a spray method and spray apparatus for bentonite-based material that allow forming a bentonite layer of high dry density. A spray apparatus | 10-08-2009 |
20090327599 | VIRTUAL TAPE DEVICE, DATA BACKUP METHOD, AND RECORDING MEDIUM - To provide a virtual tape device to reduce power consumption by utilizing a disk array device conforming to MAID. Two or more disk devices are divided into an information managing disk group whose power is kept on at all times and to two or more recording disk groups whose power is turned on/off as necessary when managing data. The virtual tape device includes: a volume information managing part which manages positions of virtual tapes allotted to storage areas of the recording disk groups; and a data managing part which rearranges, in the recording disk group whose power is on, the virtual tape for storing the data to the recording disk group whose power is off based on writing/reading information stored in the information managing disk group and positional information of the virtual tapes, and executes a control to write backup data to the recording disk group whose power is on. | 12-31-2009 |
20120099695 | FUEL GUIDE PIN, FUEL GUIDE PIN ATTACHMENT METHOD, CORE PLATE, AND NUCLEAR REACTOR - A fuel guide pin to be fixed to a core plate includes a shrink fit portion | 04-26-2012 |
20120181788 | JOINT STRUCTURE - In a joint structure, a tube member having a polygonal cross-section can be joined to a flange surface by full penetration welding with good strength margin, without imparting unreasonable force to the weld portion. The joint structure comprises a polygonal cylindrical lower guide tube joined by butt welding to a surface of a middle flange having a through-hole of the same shape as the lower guide tube, wherein at the end of the lower guide tube, within the linear portions that constitute each of the sides of the lower guide tube, there exists a weld portion welded to the surface in at least one location and an unwelded portion located separately from the weld portion, and a level difference at least as large as a distance equivalent to the weld shrinkage of the weld portion is provided between the end positions of the weld portion of the unwelded portion. | 07-19-2012 |
20140095507 | LIBRARY APPARATUS - A library apparatus according to an aspect of the present invention includes a plurality of magazines each including medium slots in which corresponding removable storage media are stored, and a magazine ID for identifying itself; at least one magazine slot each of which, at a time when one of the magazines has been loaded into itself, allocates physical slot numbers to the magazine; an ID reading unit; a logical library configuration information table including magazine presence or absence information which indicates whether or not any of the magazines is loaded in each of the at least one magazine slot; and a logical library management unit which updates the magazine presence or absence information on the basis of information indicating which of the at least one magazine slot the relevant magazine has been loaded into, and the magazine ID of the relevant magazine. | 04-03-2014 |
20150220279 | MAGNETIC TAPE DRIVE APPARATUS, MAGNETIC TAPE DRIVE SYSTEM, AND MAGNETIC TAPE DRIVE METHOD - A first system adaptation unit of magnetic tape drive apparatus communicates with a read/write request source based on a method adapted to a file system. A second system adaptation unit communicates data with the read/write request source based on a method adapted to a designated system other than the file system. A control unit allows the first system adaptation unit to be in a ready state when a format of a magnetic tape to be read and written is adapted to the file system and allows otherwise the first system adaptation unit to be in a not-ready state. The control unit deceives the read/write request source as if the first system adaptation unit is in the ready state even when the first system adaptation unit is in the not-ready state as well as the ready state. | 08-06-2015 |
20160092131 | STORAGE SYSTEM, STORAGE SYSTEM CONTROL METHOD, AND RECORDING MEDIUM STORING VIRTUAL TAPE DEVICE CONTROL PROGRAM - A storage system according to an aspect of the present invention includes: a virtual tape device that includes circuitry configured to operate as a management unit that reads a data set from a virtual tape storage unit that stores the data set, the data set including, in an associated manner, a piece of virtual tape data including a piece of user data stored in a virtual tape and management data including a piece of location data indicating a storage location at which the piece of virtual tape data is stored, a conversion unit that generates a virtual tape file including the data set, and a transfer unit that transmits the virtual tape file as transfer data to an external storage device; and the external storage device that stores the transfer data upon receipt of the transfer data. | 03-31-2016 |
