摘要： A slight-vibration-suppressing mechanism is attached to a piston rod 6 of an air pressure cylinder that stops the piston at a target position by means of a positioning control. The slight-vibration-suppressing mechanism includes a friction member formed of a pair of sealing members being in contact with the piston rod, and an air cell of compressed air fed to a periphery of the piston rod is formed by means of the friction member. An air flow path to feed and discharge the compressed air to the aforementioned air cell is formed, in which the compressed air generates a sliding friction, which suppresses slight vibration, via the friction member between the piston rod and the aforementioned friction member.

摘要： A positioning control system has a disturbance observer for estimating a disturbance from a displaced distance of a cylinder of a controlled object, and feeding back an estimated disturbance. The positioning control system also includes a saturation element and a low-pass element disposed in a feedback loop including the disturbance observer, and a saturated value changer for changing a saturated value of the saturation element based on a deviation. The saturation element is disposed in a forward path of a positive-feedback minor loop, whereas the low-pass element is disposed in a feedback path of the positive-feedback minor loop.

摘要： A suck back valve is equipped with a displacement speed regulating device made up of an ER (Electro-rheological) fluid filled in a chamber and whose viscosity changes in correspondence with the size of an external electric field, a coil member which generates the external electric field in response to an applied voltage, and a constriction which regulates a flow amount of the ER fluid between an upper-side chamber and a lower-side chamber of the chamber.
