Title: Track access unit
IPC: G11B7/085
Filed: 1992-03-23
Abstract: PURPOSE:To realize high speed and stable track access by employing a two freedom control system of feedforward and feedback in order to take advantage of the characteristics of fine and rough actuators while suppressing vibration of fine actuator at the time of seeking. CONSTITUTION:An optical disc 20 normally rotates at a constant rotational speed. Upon receiving a seek instruction from a host machine, an MPU 10 seeks a current track and then seeks a feedforward value depending on the difference between a target track and a current track. The MPU 10 further determines a target speed data for moving an optical head 31 and processes a differential signal, corresponding to the difference from an actual speed, from the count value of a period counter 14. The differential signal is then added to the feedforward value and delivered to D/A converters 11, 21. At that time, rough and fine actuators 32, 34 begin to function and an error, which can not be followed up by feedforward compensation, is dealt with feedback compensation. Upon arriving at a target track, switching is made to position control at a data section.

Abstract: PURPOSE:To correct only the display of a main timepiece while maintaining the display of a subordiate timepiece as it is by one-time operation by setting the brake torque of a control lever larger than the slide torque of a sliding mechanism. CONSTITUTION:When a main winding stem 11 is drawn axially from its normal position by two stages, a changeover mechanism operates associatively to rotate the main winding stem 11, whose rotation is transmitted from a sliding pinion 10 to an hour wheel 2, thereby correcting the display of a main hour hand.

The purpose of the use of the lever 9 is to prevent the rotation of the hour wheel 2 caused by the main hour hand correction from being transmitted to a subordinate hour wheel 8. Namely, the slide torque of a jumper wheel 3 is about 2gcm, so the lever 9 and wheel seat 6 are coupled with each other to set brake torque generated at the wheel seat 6 to >=2gm to fix the wheel seat 6, a jumper pinion 7 fixed thereto, a 24hr transmission wheel 5, and a subordinate hour wheel 8 coupled therewith; and a slide mechanism operates to rotate only the jumper gear 4, and the rotation of the hour wheel 2 is not transmitted to the subordinate hour wheel 8.
