Abstract
PURPOSE: To minutely displace a movable portion material, by changning the pressure of gas flowing between the movable portion matrial and a fixing portion mateial.
CONSTITUTION: Compressed gas is introduced from an admission hose 22, gas is flown to a clearance of a bearing between a sliding surface 13 of a movable portion material 1 and a bearing surface 26 of a fixing portion material 2, and the movable portion material 1 is floated by the gas pressure, thus ensuring non-contact supporting to the fixing portion material 2. Since the pressure of gas stream is approximately proportioned to the pressure of gas fed from the admission hose and inversely proportional to a distance of the clearance of the bearing approximately, the movable portion material 1 displaces by the pressure difference of admission hoses 22, 22a.
