Abstract
A method of applying fluid includes feeding fluid between two faces disposed with a gap maintained therebetween, and changing the gap between the two faces by driving an actuator for intermittently discharging the fluid filled in between the two faces. An input signal, in which a high-frequency component and a DC component are superimposed, is provided to drive the actuator in order to change the gap between the two faces, so that the fluid filled in between the two faces is intermittently discharged for fluid application.
