20110073603 | SAMPLE LOW-TEMPERATURE STORAGE CASE AND ORGANISM TRANSPORTATION SUPPORTING SYSTEM - The storage case has a structure in which a sample storage case (S) contained in a storage case is cooled and held at a low temperature by a Stirling refrigerator. A detection element is disposed in a room-temperature area of the storage case. The chemical or physical property of the detection element varies when a contaminant adheres to the detection element. Entrance of a contaminant into the storage case can be checked by contactlessly checking the detection element from the outside of the storage case. The storage case includes a server for receiving the result of the check from the detection device, storing the result, and setting up connection via a communication line to at least two out of a terminal operable by the forwarder, a terminal operable by the carrier, and a terminal operable by the recipient to transmit the result to the two. | 03-31-2011 |

20120155011 | STORAGE DEVICE - A storage device having a plurality of recording devices in which a decrease in vibrations from the recording devices can be achieved with a small number of parts. A storage device having a plurality of recording devices mounted therein includes a handle for inserting and withdrawing the recording device into and out of the storage device. Two holding members each include a mounting portion where the recording device is mounted and a frame extending from the mounting portion to the handle. Two protrusions are formed to extend inwardly of a region surrounded by the recording device, the handle, and the two frames. A restriction plate is disposed so as to overlap the respective surfaces of the two protrusions; and a viscoelastic body is disposed at the overlapping portion for joining the two protrusions and the restriction plate to one another. | 06-21-2012 |
20130058034 | DISK UNIT AND DISK ARRAY APPARATUS - To reduce vibration in the rotation direction acting on the hard disk drive with a part of the hard disk drive as the rotation center. | 03-07-2013 |
20130141817 | STORAGE DEVICE - In a storage device provided with a plurality of recording devices, the vibrations which propagate to the recording devices through a board can be reduced with a small number of parts. A storage device equipped with a plurality of recording devices having: a canister equipped with the recording device; a board equipped with a circuit that transmits a signal to the recording device or processes a signal; a chassis equipped with the board and the canister; a plate-like piezoelectric element attached to part of the board; a vibration detection sensor attached to part of the board; and a control unit that controls a drive signal given to the piezoelectric element in accordance with a sensor output of the vibration detection sensor is proposed. | 06-06-2013 |

20100169333 | DOCUMENT PROCESSOR - A technique to appropriately process structured data is provided. If a conditional expression related to data stored in a database system is included in a document processing apparatus, a query builder generates a query statement corresponding to the database system from the conditional expression. A database plug-in sends the generated query statement to the database system and then acquires a query result from the database system. A view builder generates a view for displaying the acquired query result. The document processing apparatus displays a display screen for a document including the generated view. | 07-01-2010 |

20100027493 | TRANSMISSION AND RECEPTION CHANNEL SELECTION FOR COMMUNICATING BETWEEN A TRANSMITTER UNIT AND A RECEIVER UNIT - A data communication network. The network includes a transmitter unit for transmitting data and a receiver unit for receiving data from the transmitter unit. The network has two or more data channels via which data may be transmitted by the transmitter unit to the receiver unit. The receiver unit includes a receiver channel selection unit for selecting a reception channel from the at least two data channels. The receiver channel selection unit operates independent from a selection of a transmission channel by a transmission channel selection unit in the transmitter unit. The transmission channel selection unit is arranged to select a transmission channel from the at least two data channels to transmit data to the receiver unit. | 02-04-2010 |
