  • Patent number: 10394662
    Abstract: A source remote copy configuration in a source storage system is migrated to a destination storage system as a destination remote copy configuration. The destination primary storage apparatus of the destination storage system defines a virtual volume mapped to the primary volume provided by the source primary storage apparatus which is a storage area of the virtual volume; takes over a first identifier of the primary volume to the virtual volume; transfers, when the virtual volume receives an access request, the access request to the source primary storage apparatus to write data in the primary volume; and takes over the first identifier from the virtual volume to another primary volume provided by the destination primary storage apparatus, after completion of copy of data from primary volume of the source primary storage apparatus into primary volume of the destination primary storage apparatus and secondary volume of the destination secondary storage apparatus.

  • Patent number: 6917054
    Abstract: A semiconductor device includes a trench formed on a source side of a drift region, a p-type gate region and a gate formed at the bottom of the trench, and the source formed over the entire surface of the unit device through an insulating film. The narrowest portion of a channel of the device is deeper than one-half the junction depth of the p-type gate region. This allows the width of the channel on the drain side to be reduced even when a lower energy ion implantation manufacturing process is used.

  • Patent number: 5926292
    Abstract: An image processing apparatus has a memory device for storing pixel image data including both halftone image data such as data of image of a photograph having a gradation and line image data such as data of text containing characters. The storage is conducted on the basis of blocks each having a predetermined number of pixels. The mean information quantity of the halftone image data per pixel stored in the memory means is not greater than the information quantity of the line image data per pixel stored in the memory means. The halftone image data being compressed on the basis of the block. Therefore, both the halftone image data and line image data can be stored in a small memory by using common addresses, without causing any degradation of the image quality.

    Abstract: An image sensing apparatus operating with adaptive selection of a first tracing algorithm in which an object image is traced by moving a detecting area capable of being movably set on an image sensing plane in such a manner that the luminance level difference between the inside and the outside of that area becomes maximum and a second tracing algorithm in which the object image is traced by moving the position of the detecting area in such a manner that a point at which a contrast becomes maximum comes to coincide with a central portion of the detecting are depending on the state of the image sensing plane. The threshold values for changing over between the first tracing algorithm and the second tracing algorithm are made to have a hysteresis characteristic.
