Abstract

PURPOSE:To control vibration more rapidly than conventionally by providing a nozzle on the lower part of an expansion pipe, blowing water or air in the horizontal direction and utilizing the reaction force of jet. CONSTITUTION:A four port connection nozzle is open on the lower part of an expansion pipe 12, and water and air jet blow into the water therefrom. At first in order to adjust the strength of the jet, the displacement of a mark is caught by an optical displacement sensor and a signal in proportion to the displacement is output. A signal in proportion to displacement represents x. Next, a time differential signal x of x is made by a differentiation factor 32. Further, the sign is changed by a proportional factor 33 and this signal to the signal which is multiplied by constant. A pump element 34 delivers water or air of the velocity in proportional to this xsix through its nozzle. The reaction force can be obtained in inversely proportional to time differential time of the displacement because the reaction force of jet is approximately directly proportional to the velocity, and so the vibration can be controlled.
