    摘要: An optical-pickup apparatus includes: a laser diode; an objective lens; a diffraction grating; a photodetector including main-beam-, first-sub-beam-, and second-sub-beam-light-receiving portions; a quarter-wave plate having either a second area allowing a reflected-laser beam to pass therethrough without polarization or a third area allowing the reflected beam to pass therethrough at a polarization angle different from that of the first area; and a polarizing member having a separate-light-amount ratio set therefor with respect to the reflected beams passing through the second or third area and an area excluding the second or third area from the first area, such that proportions of the reflected beams passing therethrough toward the photodetector are different, thereby decreasing an irradiation level when the first- and second-sub-beam-light-receiving portions are irradiated, as stray light, with the reflected beam reflected from either one, not subjected to a signal-reading operation, of the first- and second-signal-recording layers of an optical disc.

    摘要: A vibration controller includes a map controller, an adaptive controller, a set-up frequency judge/switcher, and an actuator. The map controller includes a data map storage for storing data on control signals determined in advance for a vibration insulator, and a signal generator for selecting one of the data, depending on a frequency of a cyclically pulsating signal emitted from a vibration generating source of a vehicle, from the data map storage and generating a control signal. The adaptive controller generates the control signal with respect to the cyclically pulsating signal using an adaptive control method. The set-up frequency judge/switcher switches from the map controller to the adaptive controller or vice versa based on the frequency of the cyclically pulsating signal. The actuator actuates an actuator of the vibration insulator based on the control signal generated by the map controller or the adaptive controller, whereby inhibiting the vehicle from vibrating.

    摘要: An active vibration insulator includes an electromagnetic actuator, a control-signals generating device, a driver, a calculator, and a judging device. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The control-signals generating device generates cyclic control signals based on cyclic pulsating signals output from a vibration generating source of a vehicle. The cyclic control signals actively inhibit vibrations generated by the vibration generating source from transmitting to a specific part of the vehicle. The driver drives the electromagnetic actuator by making the electric-current supplies variable based on the cyclic control signals. The calculator calculates an estimated transfer function composed of estimated values of a transfer function for a transfer system including the electromagnetic actuator and the driver. The judging device judges an inoperative malfunction of the electromagnetic actuator based the estimated transfer function.
