Patent number: 8491100Abstract: A piezoelectric ink jet head that includes a polymer film, for example a flex print, located between the piezoelectric element and the reservoirs in the jet body. The film provides an efficient seal for the reservoirs and also positions the electrodes on the side of the piezoelectric element in which motion is effected, which can reduce the magnitude of the drive voltage. This location of the compliant flex print material also can enhance electrical and mechanical isolation between reservoirs, which improves jetting accuracy. The compliance of the polymer also reduces strain on the ink jet head.Type: GrantFiled: December 2, 2008Date of Patent: July 23, 2013Assignee: FUJIFILM Dimatix, Inc.Inventors: Edward R. Moynihan, Paul A. Hoisington, Yong Zhou, Amy L. Brady, Robert G. Palifka

Patent number: 7484836Abstract: A drop ejection device includes a group of orifices adapted to eject fluid drops. The fluids ejected from the orifices merge into a fluid drop. The orifices are separated by walls which define the orifices. The merging of the fluid into a fluid drop depends on the spacing of the orifices and the waveform applied to actuators which cause the fluid to be ejected.Type: GrantFiled: September 20, 2004Date of Patent: February 3, 2009Assignee: FUJIFILM Dimatix, Inc.Inventor: Edward R.
