  • Patent number: 11945285
    Abstract: The air discharge device includes a duct defining: a main flow path through which an air flow passes; and a main hole opened in a flat shape to discharge the air flow as a working air flow toward a downstream from the main flow path. A throttle portion is provided in the duct to reduce a flow path height of the main flow path from an upstream of the air flow toward a downstream of the air flow. A plurality of partitions are arranged to divide the main flow path in a major direction into a pair of side flow paths and at least one center flow path. The plurality of partitions are disposed in the duct such that a flow path width of the center flow path is reduced from the upstream of the air flow toward the downstream of the air flow.

  • Patent number: 8737811
    Abstract: A playback device that secures coexistence of a built-in GUI for a built-in machine created uniquely by the manufacturer and a stereoscopic image created by the contents provider. A subtitle decoder displays a subtitle in a predetermined layout by decoding a subtitle stream. A GUI processing unit draws the built-in GUI. The layout of the subtitle to be displayed is one of: normal layout in which areas for subtitle display are provided both in upper and lower parts of a screen; top arrangement layout in which an area for displaying subtitle is provided only in the upper part of the screen; and bottom arrangement layout in which the area for displaying the subtitle is provided only in the lower part. When the top or bottom arrangement layout is selected as the layout of the subtitle, the GUI processing unit selects the layout of the subtitle as the layout of the built-in GUI.

  • Publication number: 20130108240
    Abstract: A reproduction control unit starts to monitor a reproduction state of a title being reproduced by a reproduction unit. If a specific navigation command added to the title being reproduced is executed, the reproduction state at a timing of the execution of this command is stored into a local storage. Moreover, the reproduction control unit determines whether or not the title being reproduced by the reproduction unit is an HDMV movie title, and in the case of the HDMV movie title, the reproduction control unit stores its reproduction state into the local storage. Resume reproduction depending on a reproduction target title is performed based on the reproduction state associated with the execution of the above specific navigation command and register information on the HDMV movie title.
