摘要:
A heat sink with fins comprising a pillar-shaped base member, and a plurality of fins which are inserted into a plurality of grooves formed in the side face of said base member and then both sides of each of said grooves are plastic-deformed to joint said fins in said base member.
摘要:
A heat sink including a base portion and a fin portion thermally contacted with the base portion. The inside of the base portion has at least one heat pipe, and a space (e.g., an air passage) formed around part of the peripheral portion of the heat pipe. The base portion is constructed of a first plate member that is contacted with a heat source, and a second plate thermally contacted with the fin portion. The heat pipe is placed between the first plate member and the second plate and is thermally contacted with them.
摘要:
A heat sink to be used with a heat source can include a base portion and a fin portion. The base portion can include a plurality of heat pipes and a space formed at least partially between adjacent heat pipes. The base portion can also include a first plate thermally connected to the heat source and a second plate thermally connected to the fin portion. The plurality of heat pipes contacts the first plate and the second plate. The plurality of heat pipes can also include a first portion that is closer than a second portion to the heat source. Additionally, a distance between adjacent heat pipes is smaller at the first portion than at the second portion.

摘要:
When data whose storage period is limited by copy control information is temporarily stored in a removable recording medium, the data are encrypted and decoding information (encryption key) necessary to decrypt the encrypted data is held on the device side. By doing so, the data cannot be used beyond a permitted period of the temporary storage. A storage device has an external input/output I/F for removably connecting a removable recording medium; a reception section for receiving copy control information and data (such as video data), the storage period of which data is limited by the copy control information; an encrypting section for encrypting the received data; and a control section for storing the encrypted data in the removable recording medium and storing decryption information (encryption key), necessary to decrypt the encrypted data, in a place in the storage device, outside the removable recording medium. The data stored in the removable recording medium can be reproduced only by the storage device.

A recording area of a hard disk is managed by units. Each unit comprises physically continuous recording regions having predetermined size, and usage status of the unit is stored in an allocation unit (AU) management table. Data requiring a real time processing is stored in each unit. When the usage status of the unit is changed or modified due to the recording or deletion of data, the AU management table is updated and then information indicative of the fact that the AU management table has been updated is recorded. An apparatus where the final change is made is detected at the time the hard disk is inserted or a file system is initialized. And if the apparatus which last made the change adopts the file system which does not use the AU management table, then the table is reconfigured so as to retain the consistency of the AU management table.

An information recording apparatus is provided which can record broadcasting information so as to accurately identify and reproduce broadcasting information to be reduced while increasing convenience in reproducing the broadcasting information.Time control is performed during reproduction in allocation units ALU based on the receiving time of the first packet and the receiving time of the last packet in the allocation unit ALU included in the broadcasting information. The allocation unit ALU includes a plurality of packets. Time control is performed also in access units, each of which includes an I picture, based on the display time information or the receiving time information of the I picture included in the packet.

A controller in a hard disk serving as a data storage device stores a license including a content key for decrypting encrypted content data E and others in a secure data storage portion. The license is managed in the secure data storage portion in accordance with a LBA, and the LBA for storing the license, which is being processed for transmission, is stored as a log in a log memory of the secure data storage portion. When a failure occurs during the transmission processing, the license, which was being processed for transmission, is specified based on the LBA stored in the log memory.
摘要:
There is disclosed a cable having a covering layer on the outside of a multicore stranded wire composed of plural insulated conductors that are intertwined, wherein at least an outermost layer of the covering layer is made of a crosslinked product of a resin composition containing (a) 10 to 60% by weight of a polyamide elastomer made up of a block copolymer whose hard segment is a polyamide, (b) 5 to 60% by weight of a thermoplastic polyurethane resin, (c) 10 to 60% by weight of a thermoplastic polyester elastomer, and (d) 0 to 20% by weight of a thermoplastic styrene elastomer. The airtightness and the watertightness at the interface between the cable and a molded body are kept for extended periods without taking any particular sealing measures. The corrosion of the conductors in the cable and the deterioration of the performance of the connected parts of machinery and tools can be prevented, and the cable has excellent water resistance.
