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： An inner member having a supply port is installed at the inside of a housing, wherein the housing and the inner member are connected together by connecting bolts. Air is supplied to the supply port of the inner member and is directed and introduced through communication passages into an annular passage. Thereafter, the air is directed outwardly from a plurality of lead-out holes, which communicate with the annular passage, in a swirling direction with respect to an annular recess facing the workpiece. In addition, by having the air flow along the annular recess, which is formed with a substantially trapezoidal shape in cross section, the workpiece is maintained in a non-contact state with respect to a holding surface of the inner member.

摘要： Disclosed is a pressure-adjusting mechanism comprising a pressure-adjusting handle, a pressure-adjusting screw for adjusting resilient force of a spring member by making rotation integrally with the pressure-adjusting handle, and a pressure-setting scale for indicating a preset pressure value by rotating the pressure-adjusting handle in a predetermined direction. As a result, it is possible to obtain the pressure-adjusting mechanism which is constructed integrally with a pressure control valve owing to a simple structure and which makes it possible to easily adjust the pressure by an operator.
