摘要： The invention is particularly applicable for the adjustment of an edge trimming saw by remote control, wherein the number of positions into which the machine element is to be adjusted is small. There is described a nonlinear system comprising a coarse adjustment for transferring the element to the vicinity of the desired point at a high velocity and a fine adjustment to transfer the body at a low velocity toward its final position. The fine adjustment is effected by a photocell device and a toothed strip of opaque material.
