摘要:
An optical transmitter and receiver has stored in advance therein FEC techniques and applicable conditions for applying the FEC techniques to a counterpart optical transmitter and receiver. The optical transmitter and receiver measures a state of receiving data transmitted from the counterpart optical transmitter and receiver, determines an applicable condition satisfying the measured data reception state from among the stored applicable conditions, and selects a FEC technique stored in association with the applicable condition determined as satisfying. The optical transmitter and receiver then notifies the counterpart optical transmitter and receiver of the selected FEC technique.

There is provided a contact type measuring instrument in which the contact force of a probe is adjusted by a force created by compressed air and an attraction force between a permanent magnet and a magnetic body. This measuring instrument gives a pulling-in force or a pushing-out force to the probe by controlling a fluid pressure in a probe body. Also, between the permanent magnet attached to the tip end of a movable part of a micrometer attached to the probe body and a plate-shaped member attached to the end part on the side opposite to a contact of the probe, an attraction force according to a distance between the permanent magnet and the plate-shaped member is created.

A carrier for cell culture which enables cells to efficiently grow thereon is provided. A carrier comprises a particulate base body mainly formed of a resin material and a coating layer. The coating layer is formed from particles of a calcium phosphate-based compound, and the particles are partially embedded in the base body at the vicinity of the surface thereof whereby the coating layer coats the surface of the base body with a calcium phosphate-based compound. Such a carrier enables cells to adhere to and grow on the surface thereof. Therefore, the carrier can be used for cell culture, especially high-density three-dimensional cell culture. The coating layer can be formed, for example, by colliding porous particles of a calcium phosphate-based compound against the surface of the base body.

A system comprising a plurality of storage systems, which uses storage devices of multiple levels of reliability. The reliability as a whole system is increased by keeping the error code for the relatively low reliability storage disks in the relatively high reliability storage system. The error code is calculated using hash functions and the value is used to compare with the hash value of the data read from the relatively low reliability storage disks.

The risk of a third party referring to or using backup data without authorization upon restoring such backup data in an HDD recorder is mitigated. First authentication information of a user as the HDD owner and second authentication information of an engineer of a repair plant are registered in an online backup service system. The first authentication information is used when backing up data recorded in the HDD to the online backup service system, and the second authentication information is used when restoring the data backed up to the online backup service system. The data backup processing and data restoration processing are executed only when the authentication information is appropriate. Since the user will directly receive an email from the online backup service system regarding who restored which data at what time, such user will be able to audit the data restoration process independently from the person recovering the data.

Provided are a content transfer system, a content transfer method, and a home server capable of backing up all backup target contents without having to transfer all backup target contents. This content transfer system includes a home storage and an online storage. The home storage transfers identifying information of a backup target content to the online storage and requests the online storage to determine the existence of a content that is identical to the backup target content upon requesting the online storage to back up the backup target content, transfers metadata to the online storage when an identical content exists in the online storage, and transfers the backup target content to the online storage in all other cases.
摘要:
Disclosed is a scanning image display device for displaying an image on a plurality of display screens. The image display device includes a light source, a scanner for two-dimensionally scanning with light from the light source, and a controller which is electrically connected with the light source and the scanner. The controller controls the light source and the scanner to form an image on the surfaces to be scanned. The scanner is configured to be capable of scanning the independent plurality of scanning surfaces with the light from the light source.
