Title: Method and device for high-speed positioning
Inventor: KAMIYA HIROYUKI
IPC: B23Q15/22
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To enable high-speed positioning while keeping positioning accuracy by detecting the vibrating state of a member to be driven generated with a target position as a center and changing a proportional gain from a high value under use at present into a low value. SOLUTION: At a vibration detection part 22, a position feedback pulse outputted from an encoder 12 is counted, this count value is compared with the number of pulses applied as the target position, and it is judged whether the member to be driven passes the target position or not. Next, when it is detected that the member to be driven is returned too much, the value of the counter for vibration detection is incremented, and this processing is repeated until the value of this counter for vibration detection reaches a prescribed count value. When this value reaches the prescribed count value, a switching signal for the value (Kp) of the proportional gain is outputted from the vibration detection part 22 to a Kp value setting part 24, and the Kp value setting part 24 switches a proportional gain Kp3 for acceleration/deceleration control to a lower proportional gain Kp4 for stop control.

And mixture ratio generator circuit 13 receives the output of circuit 3 to decide the mixture ratio between the signal of the specified frame and the signal preceding by one frame. Arithmetic circuit 2 mixes up the frame signal and the signal preceding by one frame based on the mixture ratio decided through circuit 13, and the output signal of circuit 2 is memorized through memory 4 in the form of the input. At the same time, the output is used as the signal preceding by one frame to control circuit 3 and then vary the mixture ratio.

Title: Optical disk device
IPC: G11B7/00
Filed: 1992-03-25
Abstract: PURPOSE:To suppress the occurrence of an offset drift due to temperature change by providing an automatic gain control circuit by the Gilbert type multiplying circuit of an open loop system. CONSTITUTION:The output signal of a differential amplifier OP1 is amplified and sent to the Gilbert type multiplying circuit 102 by the differential amplifier 101 of a focusing control circuit 15 and a tracking control circuit 16. Further, the output signal of the differential amplifier OP2 is amplified and sent to the Gilbert type multiplying circuit 106 by the differential amplifier 105. The output signal of an amplifier OP1 is added by an adder 109 and sent to the circuits 102. 106 as a control voltage. Thus, when the output signal of the adder 109 is small, an amplification factor becomes positive and when large, the amplification factor becomes negative, and then automatic gain control is executed. The automatic gain control circuit is constituted of the open loop type and the offset drift due to temperature change hardly occurs in comparison with a closed loop type.
