  • Information processing apparatus and information processing method
    Patent number: 8120611
    Abstract: In an information processing apparatus (1) according to the invention, a GMCH (13) is connected to a CPU (11) through a CPU bus (12), and an ICH (15) is connected to the GMCH (13) through a dedicated bus (14). The GMCH (13) includes a graphics controller (131) which borrows a part of a memory (171) mounted to a memory card (17) in order to execute display processing. A graphics card (19) can be connected to the GMCH (13). In this case, a graphics controller (131) becomes a stop state. While the graphics card (19) is connected to the GMCH (13), the CPU (11) instructs the graphics controller (13) to execute processing other than display control processing, for example, processing such as MC and IDCT. As a result, it is possible to reduce a load applied to the CPU (11).

  • Automatic paper feed device
    Patent number: 5078825
    Abstract: An automatic paper feed device provided in a turnbar unit of a rotary press includes a slitter for slitting a web of paper in half. A paper feed rope having a leader connected thereto is located near the slitter. When the leading end of the web has passed through the slitter, the paper feed rope begins to move so that the leader will be moved in juxtaposition with the leading end of one of the two slitted webs. When the leading end of one of the webs reaches a predetermined position, a tape applicator will be activated to apply tapes both to the leader and the leading end of one of the webs so as to straddle them. The web thus connected to the paper feed rope through the leader is guided by the rope through a predetermined paper feed path.
