Title: Servo mechanism
Inventor: ISHIDA MICHIYASU
IPC: G05D3/00
Filed: 1987-02-06
Abstract: PURPOSE:To restrain a controlling object from projecting out of one of the entrances of the width of resolution of a servo mechanism and reduce the quantity of variation of said controlling object by making an unbalanced load which is directed in either of positive and negative directions act on said controlling object and holding said object in a target position. CONSTITUTION:The position of a table 1 is detected and fed back to a control device, in which the difference between the detected position and a target position is calculated and a motor 4 is redriven by the resultant output signal to carry out a correcting action, and the table 1 is held in a defined target position. At this time, since the table 1 is energized in the right direction R by means of a counter weight 6, it moves heavily in the left direction L while moving lightly in the right direction R. That is, as a servo mechanism, supposing that there is no counter weight 6, the position of the table 1 would be projected out in both R and L directions beyond the width  L of the resolution. However, since the table 1 is energized in the right direction R by means of the counter weight 6, it is hard for the table 1 to be projected out in the L direction, greatly reducing the quantity of variation in the position of the table 1.
