  • Patent number: 9286000
    Abstract: Various embodiments are provided for saving a log data in a hierarchical storage management system using a disk system as a primary cache with a tape library as a secondary cache. The user data is stored in the primary cache and written into the secondary cache at a subsequent period of time. Blank tapes in the secondary cache are prepared for storing the user data and the log data, based on priorities. At least one of the blank tapes is selected for copying the log data and the user data from the primary cache to the secondary cache based on priorities. The log data is stored in the primary cache.

  • Patent number: 9189840
    Abstract: An electronic drawing generation apparatus includes: a shape determination section to determine a necessary part, which needs to be subjected to simulation, in a substrate serving as a simulation target; and a shape edit section to cut out the necessary part determined by the shape determination section from an input electronic drawing so as to prepare an output electronic drawing. The shape determination section includes a design rule check section to determine a design-rule violating part as the necessary part based on design rules stored in a design rule database.

  • Patent number: 9087515
    Abstract: A speech recognition apparatus is disclosed. The apparatus converts a speech signal into a digitalized speech data, and performs speech recognition based on the speech data. The apparatus makes a comparison between the speech data inputted the last time and the speech data inputted the time before the last time in response to a user's indication that the speech recognition results in erroneous recognition multiple times in a row. When the speech data inputted the last time is determined to substantially match the speech data inputted the time before the last time, the apparatus outputs a guidance prompting the user to utter an input target by calling it by another name.

  • Publication number: 20150095294
    Abstract: Accessing a file on a sequentially accessed storage device such as a magnetic tape often involves bypassing valid files and gaps between valid files. Presently taught is a method of copying valid files being bypassed to a second sequentially accessed storage device while not copying the gaps. When a read target file is reached, the read target file is read. During a write to a file writing position, valid files are copied to the second sequentially accessed storage device until the file writing position is reached and the file is written at the end of the valid files on the second sequentially accessed storage device.

At least one of the blank tapes is selected for copying the log data and the user data from the primary cache to the secondary cache based on priorities. The log data is stored in the primary cache. The selection of at least one of the blank tapes completely filled with the log data is delayed for writing additional amounts of the user data.
