Patent number: 8251471Abstract: Apparatus including a plurality of droplet ejection devices, an electric source and a controller. Each droplet ejection device includes a fluid chamber having an ejection nozzle, an electrically actuated displacement device associated with the chamber, and a switch having an input connected to the electric source, an output connected to the electrically actuated displacement device, and a control signal input that is controlled by the controller to control whether the input (and thus the electric source) is connected to the output (and thus the electrically actuated device). The electrically actuated displacement device moves between a displaced position and an undisplaced position to change the volume of the chamber as a capacitance associated with the electrically actuated displacement device changes in charge between an actuated condition and an unactuated condition.Type: GrantFiled: August 18, 2003Date of Patent: August 28, 2012Assignee: FUJIFILM Dimatix, Inc.Inventors: Richard E. Fontaine, Scott Leger, Daniel Cote, Paul A. Hoisington, Melvin L. Biggs, Todd W. Boucher

Publication number: 20090122118Abstract: A printhead module includes a printhead body, a nozzle plate and one or more piezoelectric actuators. The printhead body includes one or more pumping chambers, where each pumping chamber includes a receiving end to receive a printing liquid from a printing liquid supply and an ejecting end for ejecting the printing liquid from the pumping chamber. The nozzle plate includes one or more nozzles formed through the nozzle plate. Each nozzle can be in fluid communication with a pumping chamber and receive printing liquid from the ejecting end for ejection from the nozzle. The one or more piezoelectric actuators are connected to the nozzle plate. A piezoelectric actuator is positioned over each pumping chamber and includes a piezoelectric material configured to deflect and pressurize the pumping chamber, so as to eject printing liquid from a corresponding nozzle in fluid communication with the ejecting end of the pumping chamber.Type: ApplicationFiled: January 22, 2009Publication date: May 14, 2009Applicant: FUJIFILM DIMATIX, INC.Inventors: Andreas Bibl, Melvin L.

Patent number: 7326439Abstract: An apparatus for depositing droplets on a substrate is disclosed. The apparatus includes a support for the substrate, a droplet ejection assembly which includes a pumping chamber, a controller and a source of static pressure to maintain the total pressure in the pumping chamber above a threshold pressure level to avoid rectified diffusion type bubble growth in the pumping chamber. The droplet ejection assembly is positioned over the support for depositing the droplets on the substrate and includes, in addition to a pumping chamber, a displacement member and an orifice that ejects the droplets. The controller provides signals to the displacement member to eject drops.Type: GrantFiled: May 16, 2005Date of Patent: February 5, 2008Assignee: FUJIFILM Dimatix, Inc.Inventors: Paul A. Hoisington, Melvin L. Biggs, Steven H. Barss
