METHOD OF STIRRING LIQUID-LIKE OBJECT IN LIQUID DROPLET DELIVERY HEAD, AND LIQUID DROPLET DELIVERY DEVICE

摘要

PROBLEM TO BE SOLVED: To effectively stir a liquid-like object, even in a liquid-like object flow channel in a head.;SOLUTION: Liquid droplets of the liquid-like object are delivered respectively from a plurality of nozzle openings 95, by driving a piezoelectric element 120 provided in each of the plurality of the nozzle openings. The method includes a process for making the liquid-like object corresponding to the piezoelectric element flow at different pressure, by making different a driving state of the piezoelectric element.;COPYRIGHT: (C)2010,JPO&INPIT
