Motion is such that the time taken to move from the first position to the second position is longer than the time taken to move from the second position back to the first position.

Abstract: A cam mechanism incorporating a highly precise bearing structure that improves the dynamic stability of the cam mechanism's rotating output component. Relevant structures consist of a worm gear driven rotating shaft driving a rotating output shaft supported by a cross roller bearing assembly incorporating V-shaped inner and outer bearing races that sandwich and ride over a set of rollers. Of particular note is that the outer or inner bearing race may be formed as a groove machined directly into the circumferential surface of the output shaft. Because the outer bearing race is a ring-shaped structure that concentrically surrounds the rotating output shaft, the output shaft and bearing races can be machined simultaneously as a single workpiece to assure a high degree of concentricity between the shaft and bearing races.

Abstract: A torque limiting device capable of transferring torque within a power train, and also capable of disengaging the torque transfer connection when the torque level exceeds a specific point. A specific ball bearing joint is formed where a radial boss mates with the inner circumference of a flange. The ball bearing joint consists of an outer radial groove formed on the aforesaid inner circumference, an inner radial groove formed on the boss and facing the outer groove, and ball bearings inserted between the two radial grooves. Each radial groove is formed to a V-shape cross section having a radius of curvature smaller than that of the ball bearings, thus providing ball bearing support at two points within each groove, and four points of bearing support in total. Rotation of the torque output part is thus supported adequately in both the radial and axial thrust directions by a single ball bearing structure which allows the torque limiter to be made to compact dimensions.

Abstract: The present invention relates to a carrier apparatus for clamping a work by a two-dimensional rectangular motion of a pair of feed bars to automatically carry the work linearly. The carrier apparatus has at least three cams for feed and clamp rotated by an input shaft. Each of the rotational motions of these cams is transmitted to a pair of bars in parallel through the paired turrets and paired motion conversion mechanisms in the form of rectangular motions. These rectangular motions in the both feed bars are applied to the clamping motion and the feed motion for carrying the work.
