Publication number: 20090322187Abstract: Microelectromechanical systems with structures having piezoelectric actuators are described. The structures each have a body that supports piezoelectric islands. The piezoelectric islands have a first surface and a second opposite surface. The piezoelectric islands can be formed, in part, by forming cuts into a thick layer of piezoelectric material, attaching the cut piezoelectric layer to a body having etched features and grinding the piezoelectric layer to a thickness that is less than the depths of the cuts. Conductive material can be formed on the piezoelectric layer to form electrodes.Type: ApplicationFiled: May 4, 2009Publication date: December 31, 2009Applicant: FUJIFILM Dimatix, Inc.Inventors: Andreas Bibl, John A.

Patent number: 7413300Abstract: An ink recirculation assembly includes a main ink inlet configured to receive ink from an ink source, a main ink outlet configured to direct ink toward an ink source, and a channel extending from the main ink inlet to the main ink outlet. The channel includes an inlet portion and an outlet portion. A pressure differential is formed across the inlet and outlet portions, for example, by a constrictor separating said portions. The inlet portion is configured to move ink from the main ink inlet to openings formed in the inlet portion, said openings configured to direct ink toward ink inlet channels for each of multiple printhead modules. An outlet portion is configured to move ink away from openings formed in the outlet portion toward the main ink outlet, said openings configured to receive ink from ink outlet channels for each of the multiple printhead modules.Type: GrantFiled: April 27, 2005Date of Patent: August 19, 2008Assignee: FUJIFILM Dimatix, Inc.Inventors: Kevin Von Essen, John A.
