Abstract: An objective of the present invention is to secure the continuity of the communication between a client device and a standby server device, when a failure occurs and switch to the standby device is performed. A communication processing unit of the client device establishes connection with a plurality of server devices simultaneously by transmitting a UDP packet to the plurality of server devices by multicast. After establishing the connection, data of the application is transmitted by multicast to the plurality of the server devices. In the even of a failure, a standby server device receives the data packet multicast from the client device to continue the inter-application communication.

Abstract: A secondary texture cache is used commonly by a plurality of texture units, and stores part of texture data in a main memory. A cache controlling CPU controls a refill operation from the main memory to the secondary texture cache in accordance with cache misses of the plurality of texture units, so as to suppress occurrence of thrashing in the secondary texture cache. The cache controlling CPU suppresses occurrence of the refill operation when the plurality of operating units access an identical memory address with a predetermined time difference.

Abstract: An electric storage device is provided with a battery cell, a collector foil having a first metal plate and a second metal plate laminated together, and a voltmeter for measuring potential difference between the first metal plate and the second metal plate.

Abstract: The backup server in the backup site receives messages multicast from business servers in the primary site, extracts the business data, and stores it in backup databases for each business server. Upon this storing of business data, the sequence numbers in the messages are added to the business data to be stored in the backup databases. Detection of loss in sequence numbers allows the detection of which piece of the business data is lost. The backup server does not request a business server in the primary site to retransmit data even when business data is partially lost, but instead directly requests the database server in the primary site to transmit the lost business data.

Abstract: This invention enables to generate encoded data without noticeable image quality degradation when reproducing an image at a lower resolution not to mention the original resolution. An image a digital camera can capture takes three sizes L, M, and S. When the size L is designated, stream conversion information SC is set to “2”. When the size M is designated, the stream conversion information SC is set to “1”. When the size S is designated, the stream conversion information SC is set to “0”. When encoding image data in compression processing, block overlap processing of suppressing discontinuity of data at the boundary between adjacent blocks is executed as many times as the count set in the stream conversion information.

Abstract: This invention enables to generate encoded data without noticeable image quality degradation when reproducing an image at a lower resolution not to mention the original resolution. To accomplish this, when setting is done to transmit an image captured by a digital camera to a network, code stream forming information CF is set to “2” to arrange the encoded data of each tile in a resolution order. To suppress image quality degradation when reproducing at an intermediate resolution, stream conversion information SC is set to “2”. When encoding image data in compression processing, block overlap processing of suppressing discontinuity of data at the boundary between adjacent blocks is executed as many times as the count set in the stream conversion information. The obtained encoded data is arranged in accordance with the code stream forming information CF and output.

Abstract: A laminated core segment 30 into which a stator core is split has a core main body 31 that extends in an arc shape. On one end section of the core main body 31 there is formed a connecting section 40, and on the other end section there is formed a connecting section 41. The connecting section 40 is able to connect with the connecting section 41 of another laminated segment 30. In the connecting section 40 there is provided a protruding protrusion section 48, and the protrusion section 48 interferes with an interference section 53 on the connecting section 41 side when the stator core 30 is forced towards the direction in which the stator core is split. As a result, an assembly operation of the stator core becomes easier, and a magnetically excellent connecting structure can be obtained.

Abstract: Introduced is an end-point bridge that relays an end point—formed by an external bus in a device tree managed by a first processor unit and an end point formed by an external bus in a device tree managed by a second processor unit. A conversion unit in the end-point bridge replaces a requestor ID contained in an access request packet, for example, which has reached the end point, to the ID of the end point from the ID of a host bridge. The ID of the host bridge is stored in a memory in a manner that the ID of the host bridge is associated with a tag of the packet, and is used to return the requestor ID when a response packet to the request reaches the end point.

Abstract: There is provided a technique of accessing a memory of a processor from a peripheral device, thereby the security is ensured while efficiency is being pursued. An address converter 14 includes an address conversion table for converting an effective address into a physical address. The address conversion table stores the effective address to which an area in a memory of a processor unit 10 is allocated to each peripheral device 30 and identification information of an access source to which access permission is given, in association with each other. When the peripheral device 30 accesses, the address converter 14 determines to permit access to the effective address under the condition that the device identification information, included in an access request packet, by which the peripheral device 30 can be uniquely identified, matches the identification information of the access source corresponding to the effective address, in the address conversion table, designated by the access request packet.

Abstract: In a brushless motor for an electric power steering device having a configuration of 2 poles and 3 slots, or of an integral multiple thereof, a stator coil is supplied with current containing a higher harmonic component. A difference of 0.5% to 1.5% is provided between the higher harmonic component content rate of the stator coil current and the higher harmonic component content rate of the induced electromotive force generated in the stator coil with rotation of a permanent magnet, thereby mitigating the influence by an armature reaction generated in the induced electromotive force to reduce torque ripples. The difference between the higher harmonic component content rates is set on the basis of a change that occurs in the induced electromotive force due to the armature reaction at a time of supplying electricity to the armature coil.
