    摘要: An ultraviolet curable composition having, a coating film cured with ultraviolet rays with a large number of crosslinking points due to a (meth)acrylate compound that does not intramolecularly have a cyclic moiety and has a functionality of three or more and, the compound does not intramolecularly have a cyclic moiety, plastic deformation due to a cyclic moiety is less likely to occur. Additionally, a monofunctional (meth)acrylate compound forms a homopolymer having a glass transition temperature of 20° C. or less, has a low glass transition temperature, and is flexible. Curing contraction caused in ultraviolet curing is suppressed and plastic deformation is less likely in the resultant cured film at room temperature. An optical disc employing the above ultraviolet curable resin composition reduces warpage; and rapid recovery from deformation caused even by application of a load for a long period of time or as a result of an impact due to falling.

    摘要: To provide a database which has plural log storage areas, and eliminates the sort in the restoration process by means of the application of logs, thereby carrying out the restoration quickly. A management server allocates DB servers to a corresponding one of plural data storage areas so as to access the corresponding one. The DB servers store data to the allocated data storage areas. When the data is referenced or updated, a log representing a data change history is stored in preset log areas for each data server. When the management server transmits a notification to change the data storage areas, area remapping logs are stored in log areas.

    摘要: A database management method for updating data of a duplicated ID sequential arrangement table and arranging segments of data with respect to the arrangement table includes managing a management table holding the arrangement table name and a name of a duplicated key column, arranging a new row in an empty space in a first partial set of segments of rows having identical values in the duplicated key column to that of the new row, searching for a sequential empty space having capacity larger than that needed to hold the first partial set of segments of rows, and moving the first partial set of segments of rows to the sequential empty space and arranging the new row in a different set of segments if the sequential empty space is found or arranging the new row in a new segment if the sequential empty space is not found.

    摘要: In a back electromotive force phase detecting device, a timing generating unit generates a timing signal indicating a start timing, an intermediate timing and an end timing of a 180-degree electrical angle period in a detection target phase, from an excitation pulse signal. A difference calculating unit receives the timing signal, and calculates a difference between a total PWM control period of the detection target phase during a first-half 90-degree period, and a total PWM control period of the detection target phase during a second-half 90-degree period. In an excitation control device, a control unit changes the capability of driving a motor based on an output of the back electromotive force phase detecting device.
