ELECTROSTATIC ACTUATOR, LIQUID DROP DISCHARGE HEAD AND INKJET RECORDER

摘要

PROBLEM TO BE SOLVED: To solve the problem that stable and high discharge efficiency and discharge characteristic cannot be obtained at low costs. SOLUTION: A plurality of electrodes 14a and 14b comprising conductive structural bodies electrically isolated and separated from each other are set at a diaphragm 10 for constituting walls of discharge chambers 6 which communicate with nozzle holes 4. The plurality of electrodes 14a and 14b are formed in a plane shape to go around. COPYRIGHT: (C)2003,JPO
