  • Publication number: 20090193235
    Abstract: In response to a transfer request, for which a loading time at a transfer source and a loading time at a transfer target are designated by a production controller, there is created a transfer scenario, which contains a basic transfer (From) from the transfer source to a buffer near the transfer target, for example, and a basic transfer (To) from the buffer to the transfer target. In order that the basic transfers (From, To) may be able to be executed, the buffer is reserved, and a transfer vehicle is allocated. The time period for the transfer vehicle to run to the transfer source or the buffer and the time period for the transfer vehicle to run from the transfer source or the buffer are estimated to assign a transfer command to the transfer vehicle. The possibility that the loading and the loading time may deviate from a designated period is evaluated. In case this possibility is high, a production controller is informed that a just-in-time transfer is difficult.

  • Patent number: 7304920
    Abstract: An optical head that detects a tilt in an optical disk. The optical head includes a condensing means, a light receiving means, a tracking error signal detection means, and an optical tilt detecting means. The light receiving means includes at least first and second light receiving areas, the first light receiving area being a rectangle having long sides that extend in a direction perpendicular to information tracks on the optical disk. The tracking error signal detection means detect error signals corresponding to light signals received in the first and second light receiving areas. The optical disk tilt detection means compare the tracking error signals to detect a radial tilt in the optical disk. In an alternative embodiment, the long sides of first light receiving area extend in a direction parallel to the information tracks, and the optical disk tilt detecting means detect a tangential tilt in the optical disk.
