Abstract: A winding of a transmission coil included in a power transmission device of a contactless power feed apparatus and serving to transmit AC power to a power reception device contactlessly is formed of a wiring pattern provided on a substrate. The transmission coil is divided into partial coils arranged coaxially. Each of the partial coils is formed such that, among the partial coils, a number of turns of a winding included in a partial coil is larger as the partial coil is located more outwardly.

Abstract: A transmission and reception apparatus, includes a processor and a processing device coupled to the processor, wherein the processor is configured to detect insertion of a pluggable module, issue, when the insertion of the pluggable module is detected, an instruction to the processing device to generate a first test signal to be supplied to the pluggable module, extract an alternating current component from a first monitoring result of the first test signal by the pluggable module and acquiring pulse width information at a plurality of phase points, and set a phase point determined based on the pulse width information as an optimum phase value to the processing device.

Abstract: An information providing apparatus according to an embodiment includes a terminal information acquiring unit, a store information acquiring unit, and a sending unit. The terminal information acquiring unit acquires information on purchase planned products which is sent from a wireless terminal existing in a store in which a wireless LAN communication apparatus is installed, from the wireless LAN communication apparatus.

Abstract: A transmission system includes: a sending apparatus; a receiving apparatus; and an intermediate apparatus, the sending apparatus, the receiving apparatus and the intermediate apparatus being connected in a ring shape via a first transmission line used to transmit a first channel signal and a second channel signal in one direction and a second transmission line used to transmit the first channel signal and the second channel signal in another direction opposite to the one direction, the receiving apparatus including a first phase adjustment unit that adjusts a phase difference between the first channel signal of the first transmission line and the first channel signal of the second transmission line, and the intermediate apparatus including a second phase adjustment unit that adjusts a phase difference between the second channel signal of the first transmission line and the second channel signal of the second transmission line.

Abstract: When a database area multi-written or replicated in an external storage unit is separated, a database management system writes consistent data into the external storage unit. A method and system capable of controlling a timing of separating the replicated database area is provided. Furthermore, new data directory information necessary to access the replicated database is dynamically added based on the data directory information of the replication source database. A method and system capable of selecting whether to access the database which is the source of the replication or access the replicated database are provided. Thus, when the database area multi-written or replicated in an external storage unit is separated and physical replicated databases are created, it is possible to maintain consistency of the replicated databases while continuing transaction processing.

Abstract: A replication data base is created on the basis of a predetermined condition. A data processing system adds transactions that are lacking and/or cancels transactions that are not required, to and from a replication data base created on the basis of a certain arbitrary time, in accordance with a predetermined condition defined by the data base user.

Abstract: A data processing apparatus includes a storage device having a replication generation function for replicating a data base to create a replication data base, and stores data and a plurality of log information in transaction processing that uses the data in the storage device, selects a transaction that is performing a data operation without meeting a predetermined condition after synchronization between the data base and the replication data base is released, and performs the data operation cancellation processing to the replication data base by the selected transaction. It also selects a transaction, which meets the predetermined condition and is not performing a data operation to the replication data base, to perform a data operation to the replication data base with the selected transaction. It then becomes possible to reduce the burden for the data processing apparatus during using the replication data base.
