| 20090109262 | FLUID EJECTION DEVICE - A fluid ejection device includes a fluid chamber having a first sidewall and a second sidewall, a flexible membrane extended over the fluid chamber and supported at an end of the first sidewall and an end of the second sidewall, an actuator provided on the flexible membrane, a first gap provided between the flexible membrane and the end of the first sidewall, and a second gap provided between the flexible membrane and the end of the second sidewall, and compliant material provided within the first gap and within the second gap. As such, the actuator is adapted to deflect the flexible membrane relative to the fluid chamber. | 04-30-2009 |
| 20110050808 | PIEZOELECTRIC PRINTHEAD AND RELATED METHODS - A piezoelectric printhead and related methods provide a first metallic electrode and a second metallic electrode deposited over a top surface and a bottom surface, respectively, of a piezoceramic plate. The second electrode is segmented into a plurality of electrode segments. A diaphragm is positioned over a plurality of pressure chambers, where the diaphragm includes a conductor positioned over each chamber. The piezoceramic plate is attached to the diaphragm such that each conductor on the diaphragm faces multiple electrode segments. | 03-03-2011 |
| 20110102516 | Printhead unit - Piezoelectric unit, comprising a fluid chamber, a fluid outlet, an actuator, comprising a thin film piezoceramic element and a membrane, acting as a wall of the fluid chamber, and a support element arranged for preventing a supported portion of the actuator from movement in a main direction of actuation movement of the actuator, while allowing such actuation movement on at least two sides of the supported portion, wherein the support element is connected to a unit portion that extends approximately opposite to the actuator. | 05-05-2011 |
