  • Patent number: 6954414
    Abstract: A drive current or a drive voltage is controlled corresponding to change of load by sampling the drive current or drive voltage of a motor to move an optical pickup and then detecting change of the sampling signal as change of the optical pickup when it is moved. Moreover, change of the sampling signal is obtained from a difference of the sampling signals by comparing these sampling signals at the first and second points. Comparison of these sampling signals is conducted in unit of drive pulse.

  • Publication number: 20030095962
    Abstract: This invention provides a system for controlling the phenotypic characteristics of cells. A pair of chimeric polypeptides is anchored in the plasma membrane, each of which has a variable region sequence and an effector sequence. The polypeptides are independent in the absence of antigen, but form a stable complex with each other when antigen is provided. This drives the effector sequences together in a manner that produces a receptor activation signal, leading to a phenotypic change. By titrating the amount of antigen present in the environment, the degree of phenotypic change can be regulated. Cells bearing chimeric polypeptides can be used to measure the concentration of antigen or select cells transfected with a therapeutic gene.

  • Patent number: 6308002
    Abstract: Picture data received in the order of DC components and AC components is stored in a frame memory 115. At this point, an ID number detecting portion 117 detects an ID of a sync block and sends the detected ID to an encoding portion 114. Corresponding to the ID, the encoding portion 114 determines whether or not data that is read from a frame memory 93 is a buffering unit that has been stored. Thus, when the read data is the buffering unit, the read data is output as it is. When the read data is not the buffering unit, gray data is output.

  • Patent number: 5777952
    Abstract: A bias magnet unit has a permanent magnet that applies a bias magnetic field to an optical spot on a magneto-optical disk. A driving coil rotates the magnet in order to change a polarity of the bias magnetic field. A sensor detects the intensity and polarity of the bias magnetic field to confirm the rotational position of the magnet after it has been rotated. A linkage structure that is connected between a magnet holder of the magnet unit and the housing has arms that drive the magnet unit between two positions, one in which the magneto-optical disk cartridge can be inserted into the device and another in which the disk is loaded onto the spindle motor for recording/playback. Overall, the components of the device cooperate structurally to provide a relatively thin device structure having low power consumption.
