20090036549 | SUBSTANCE-ENCAPSULATED CARBON NANOHORN COMPLEX AND PRODUCING METHOD THEREOF - A cap of polyamine molecules is provided on an aperture portion of carbon nanohorns having apertures formed by oxidation. The polyamine cap opens and closes according to the pH of the ambient environment, thereby controlling release of an encapsulation substance. | 02-05-2009 |
20090208567 | SUBSTANCE-CONTAINING CARBON NANOHORN COMPOSITE HAVING POLYAMINE PLUG AND PROCESS FOR PRODUCING THE SAME - The present invention provides: a carbon nanohorn composite including a carbon nanohorn, a substance encapsulated in the carbon nanohorn, and a polyamine adsorbed by chemical reaction firmly to a surface functional group present on the opening part on the surface of the carbon nanohorn, wherein the release amount and release rate of the encapsulated substance can be controlled using the difference in size, substituent or three-dimensional structure of the polyamine, which is used as a plug; a method of controlling the release of the encapsulated substance; and a process for producing the carbon nanohorn composite. The release amount and release rate of the substance encapsulated in the carbon nanohorn composite is controlled by selecting a polyamine molecule, which plugs the opening part formed in the carbon nanohorn by oxidation, by its size, substituent or three-dimensional structure. | 08-20-2009 |

20120058053 | CARBON NANOHORN MRI CONTRAST AGENTS - A contrast agent characterized in that each of carbon nanohorns forming a carbon nanohorn aggregate has an opening at the side wall or tip, wherein a metal M (at least one metal selected from among paramagnetic metals, ferromagnetic metals, and superparamagnetic metals) or a compound of the metal M is incorporated in or dispersed on each of the carbon nanohorns. A contrast agent characterized in that it contains a Gd oxide. There is provided a contrast agent, which can be mass-produced easily, and satisfies the requirement of low toxicity and enables microscopic diagnoses when used for MRI. A contrast agent characterized in that is contains a carbon nanohorn aggregate. | 03-08-2012 |

20090199049 | PROGRAM PROCESSING DEVICE AND PROGRAM PROCESSING METHOD - A program processing device has a non-volatile storage, a volatile storage and a controller. The controller has a detector that detects a bit flip in the program, the variable data, and the constant data in the volatile storage, a constant recovery unit that, when the detector detects an error in the constant data, writes the constant data in the non-volatile storage into the volatile storage, and then continues the execution of the program from a point at which the program was being executed before the detector detected the error, and a restart that, when the detector detects an error in one of the variable data and the program, writes the program, the initial value of the variable data, and the constant data in the non-volatile storage into the volatile storage, and then executes the program written into the volatile storage from a beginning of the program. | 08-06-2009 |
20100037223 | METHOD FOR CONTROLLING STORAGE APPARATUS AND STORAGE APPARATUS - A method for controlling a storage apparatus includes rearranging an order of execution of commands supplied from an external apparatus and queued in the storage apparatus so as to optimize execution of commands, and adjusting a maximum retry time of a command on the basis of a passage time from receipt of the command, the maximum retry time being defined for each command. The adjusting includes at least one of a first adjustment and a second adjustment. The first adjustment reduces the maximum retry time of at least one of the commands queued in the storage apparatus on the basis of the passage time of said at least one of the commands at a first timing when the order of execution of commands is rearranged. The second adjustment reduces the maximum retry time of a selected command to be executed in the storage apparatus on the basis of the passage time of the selected command at a second timing before the selected command is executed in the storage apparatus. | 02-11-2010 |
20100131723 | ACCESS CONTROL APPARATUS, ACCESS CONTROL METHOD, AND STORAGE APPARATUS - According to one embodiment, an access control apparatus is configured to convert a logical address into position information of a physical sector to control access to a storage medium. The access control apparatus includes an access mode specifying command processing module and an access processing module. The access mode specifying command processing module receives an access mode specifying command specifying an access mode that defines a relationship between the logical address and the physical sector, and stores the access mode in an access mode storage module. The access processing module refers to the access mode storage module to determine an access mode for accessing the storage medium. | 05-27-2010 |

20140304547 | DRIVE ARRAY APPARATUS, CONTROLLER, DATA STORAGE APPARATUS AND METHOD FOR REBUILDING DRIVE ARRAY - According to one embodiment, a drive array apparatus includes a plurality of data storage drives constituting a drive array and a controller. The controller divides all data storage areas of each of the data storage drives into a plurality of logical unit areas and associates and manages each of the logical unit areas and each of the data storage drives. The controller identifies a logical unit area of an error occurrence object based on a notification from a data storage drive where an error occurred, restores data of the identified logical unit area, and performs reconfiguration processing of the drive array. | 10-09-2014 |
