  • Patent number: 11970004
    Abstract: A liquid discharge head includes a liquid discharge substrate that has a discharge-orifice row, pressure generating elements, and pressure chambers. The liquid discharge head discharges a liquid in a block-by-block manner using sequential driving. The discharge-orifice row is disposed so as to incline at an angle ?=Arctan (d1/d2) relative to a direction extending orthogonal to the conveyance direction of the medium, in which d1 (?m) is a disposition spacing of the discharge orifices in the discharge-orifice row in the conveyance direction and d2 (?m) is a disposition spacing of the discharge orifices in the discharge-orifice row in the direction orthogonal to the conveyance direction. A partition wall is formed between adjacent pressure chambers so as to separate the adjacent pressure chambers from each other. The partition wall has a communicating portion that communicates the adjacent pressure chambers with each other.

  • Publication number: 20070160346
    Abstract: A reading apparatus for reading data from a digital versatile disc (DVD) generates information indicating a plurality of predetermined portions of content stored on the digital versatile disc, based on navigation information of the DVD on which the content is recorded. A storage reads the predetermined portions from the DVD based on the generated information and stores the predetermined portions on a storage medium. A reading control section controls reading of data from the DVD and the storage medium so that the data of the predetermined portions stored on the storage medium is read and data subsequent to the data read from the storage medium is read from the DVD if reading of the data of the content is requested.
