| 20110134193 | NOZZLE ARRANGEMENT WITH AN ACTUATOR HAVING IRIS VANES - A nozzle arrangement for an inkjet printhead includes a substrate defining an ink inlet; a plurality of posts extending from the substrate; a roof portion defining an ejection port, the roof portion supported by the plurality of posts; a plurality of vanes extending from the substrate and arranged to form a wall of a chamber around the ink inlet; and a plurality of thermal bend actuators respectively positioned at a base of each vane, each thermal bend actuator having a fixed end in the vicinity of one of the plurality of posts and a displaceable end opposite the fixed end. The plurality of thermal bend actuator are adapted to bend said vanes inwards with respect to the chamber in an iris-type manner to reduce a volume of the chamber, whereby ink is ejected from the chamber via the ejection port. | 2011-06-09 |
| 20110134194 | PIEZOELECTRIC DEVICE AND METHOD FOR MANUFACTURING THE SAME, PIEZOELECTRIC ACTUATOR, LIQUID EJECTING HEAD, AND LIQUID EJECTING APPARATUS - A piezoelectric device includes: a substrate; a first electrode formed over the substrate; a first piezoelectric element formed over the first electrode; a low density region which is formed at a side of the first piezoelectric element and has density lower than that of the first piezoelectric element; a second piezoelectric element which is formed to cover the first piezoelectric element and the low density region; and a second electrode formed over the second piezoelectric element. | 2011-06-09 |
