  • Patent number: 9880765
    Abstract: [Object] Copy processing time is reduced by selecting an optimum copy method according to the content of difference data and the status of a system. [Solution] When the primary disk storage apparatus and the secondary disk storage apparatus are separated from each other after dual writing operation and a copy pair regarding which data is written to only the primary disk storage apparatus is to be resynchronized, the host computer selects either host-computer-based copy processing executed via the host computer or inter-disk-control-device copy processing executed between the first disk control device and the second disk control device, on the basis of information about copy processing including a difference data amount between the primary disk storage apparatus and the secondary disk storage apparatus, a data transfer amount between the respective apparatuses, and performance information of each apparatus.

  • Publication number: 20180026134
    Abstract: In an LDMOS having an element isolation region of an STI structure, there is prevented an occurrence of insulation breakdown which might be caused when electrons generated in a semiconductor substrate near an edge portion of a bottom face of the element isolation region are poured into a gate electrode. Immediately over an upper surface of an offset region adjacent to the element isolation region embedded in a main surface of the semiconductor substrate between a source region and a drain region, there is provided a trench penetrating a silicon film forming the gate electrode. As a consequence, the silicon film and a metal film for filling the trench form the gate electrode.

  • Publication number: 20180018136
    Abstract: While a specific application is running, a printer driver enables printing other data that is not data from the specific application. A dedicated driver (printer driver) that runs on a POS terminal occupies a communication port when receipt data is supplied from a POS application. The dedicated driver also sends print data generated based on the receipt data through the communication port to a POS printer. After continuing for a previously set time, the dedicated driver releases the communication port.
