    摘要： A ball screw apparatus having a revolving position detector for detecting revolutions of a ball screw nut and a ball spline nut and a number-of-revolutions altering means for issuing a command to decrement or increment the number of revolutions of the ball screw nut so that a difference between sets of revolution numbers becomes zero. In the ball screw apparatus, a driving motor is disposed in parallel with a driving shaft. An output of the driving motor is transmitted via a belt to each nut. When driving the motor in a clutch-off/brake-on state, only the ball screw nut is driven to revolve, and the driving shaft is slid in the axial direction. When driving the motor in a clutch-on/brake-off state, the two nuts revolve together, and the driving shaft is rotationally driven. A reduction ratio on the side of the ball screw nut is set equal to that on the side of the ball spline nut, whereby the two nuts synchronously revolve.

    摘要： A digitally controllable pneumatic linear actuator in which a moving piston driven by compressed air is initially decelerated by the pressure of compressed air applied to the both sides thereof in the course of its advancing movement toward a predetermined stop position and is then braked by a mechanical brake, thereby obviating failure of precise positioning of the piston due to the compressibility of air. The piston displacement is digitally detected, and the result of detection is fed back to a digital controller.

    摘要： A computer assisted manual machine tool system and method for milling, turning and grinding uses a computer model of machine objectives and location feedback signals from the tool to control motion switch means enabling and disabling tool motion. The manual machinist may position a tool to a target position by enabling motion along each controlled axis while the tool's position feedback for that axis is outside of the tolerance specification and disabling motion once the tool is within that tolerance. The machinist may contour within a specified tolerance zone by toggling the motion switch means for each axis to produce motion along that contour. The machinist may pocket by enabling motion while the tool is away from the pocket surfaces and disabling motion when the tool position is within a predetermined distance of any pocket surface.
