  • Patent number: 7603517
    Abstract: A disk storage device stores write data in a cache area of a data buffer according to a write command from a host, reports write completion to the host, and then writes the write data in the cache area to a storage medium. The disk storage device stores the write data stored in the data buffer in a save area created on the storage disk in response to the reception of a command which requires integrity, other than a write command, and reports a response to the host. Therefore processing time of this command and response time to the host can be decreased, while maintaining the safety of the write data.

  • Patent number: 7118207
    Abstract: Ink for use in an ink-jet color recording apparatus and a plurality of kinds of small microcapsules dispersed in the solvent, each small microcapsule having an outer shell destroyable with ultrasonic waves of a predetermined resonant frequency, each small microcapsule containing a color former within its outer shell with the outer surface of the outer shell covered with a developer. The plurality of kinds of small microcapsules are destroyed selectively with the corresponding predetermined stimuli to thereby produce magenta, cyan, yellow or black. The ink is colorless before producing the color. The ink-jet color recording apparatus irradiates the plurality of small microcapsules with ultrasonic waves of a selected frequency corresponding to a desired color to thereby change the color of the ink on a path through which the ink is fed from a color ink feeding device to an ink cartridge.

  • Patent number: 7022444
    Abstract: A color image forming method and apparatus using larger microcapsules each of which contains a plurality of kinds of smaller microcapsules scattered within the larger microcapsule, reacting substances that are mixed with each other to perform a coloring reaction being scattered inside and outside the smaller microcapsule. A protective wall of each smaller microcapsule is broken with a corresponding predetermined ultrasonic stimulus depending upon color component information to thereby cause the reacting substances to diffuse with each other to perform a coloring reaction and hence image printing. The conditions for breaking the protective walls of the respective smaller microcapsules that contain a color former component vary from smaller microcapsule to smaller microcapsule, or are determined depending upon the outer shapes, materials and thickness of the protective walls of the smaller microcapsules.
