IPC: G11B7/09
Filed: 1981-12-28
Abstract: PURPOSE:To cause a beam to strike a track invariably at right angles and to detect a signal of good quality without deterioration in ON ratio, by floating an objective lens through a magnetic mechanism and adjusting its position to the track of a disk. CONSTITUTION:A cylindrical objective lens frame 1 holding the objective lens faces the disk 2 at distance. A pickup 3 having the objective lens frame 1 is freely movable in the radius direction over the disk through a leading mechanism which is not shown in a figure. This pickup 3 is provided with the 1st magnetic mechanism 4 and the 2nd magnetic mechanism 5 which float the objective lens frame 1 and adjust the position of laser light to a track of the disk 2. If the floating disk 2 rotates eccentrically to cause radius-directional track oscillation, a tracking control signal is detected. Then, the objective lens frame 1 is driven in a tracking direction B by a control signal current based upon the obtained tracking control signal. At this time, the 1st magnetic mechanism 4 provided vertically moves the objective lens frame 1 in parallel, and consequently the beam passed through the objective lens in the frame 1 traces one track invariably at right angles to the track while following up the track oscillation.

Title: Feedback controller
Inventor: ITO YOICHI
IPC: G05F1/44
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily control the quantity of DC offset by compensation, by providing means of determining an estimate of disturbance by operation. SOLUTION: When operating an estimate of disturbance, the same effect as inserting a filter of particular frequency characteristics to this power control system can be obtained, and a DC component of a main circuit (control system) containing a transformer 3 is restricted and also the drift excitation of a transformer 3 is restricted. In short, the frequency characteristics lower than 0 dB at DC and its vicinity in a current control system means that the DC component is hard to flow into a control target including a transformer 3, and the drift excitation of a transformer 3 is prevented. In this way, if the DC component can be restricted by a current controller, then the drift excitation can be prevented even though the DC offset has not been adjusted strictly to zero at current detectors 7u, 7w, 10w and A/D converters 8, 11 and so forth.

Abstract: PURPOSE:To improve the sensitivity of interruption of a transmission signal when the crosstalk from a receiver to a transmitter is less by providing a loss quantity control circuit. CONSTITUTION:The 1st loss variable element VR1 of a transmission side transmission loss control circuit 21 is controlled by a control voltage proportional to the difference between an output level of the sending-side 1st amplifier circuit 32 and an input level of the reception-side 2nd amplifier circuit 42. That is, when the reception signal level is larger than the transmission signal level, the 1st loss variable element VR1 of the circuit 21 acts like decreasing the transmission loss of the transmission signal line and when the difference is larger, the transmission loss is decreased. Thus, when the reception signal is inputted and the crosstalk from a speaker 43 to a microphone 31 exists, the difference between the transmission signal level and the reception signal level is decreased to increase the transmission loss of the transmission signal line and the loop gain of a loop comprising a microphone 31, a side tone prevention circuit 3, a speaker 43 and the microphone 31 is limited to prevent howling.
