摘要： An ink jet print head includes an ink chamber defined by an electrostatically actuated membrane and a nozzle plate opposing the membrane. The nozzle plate includes a nozzle hole and a group of priming holes, the priming holes configured to maintain a substantially ink free surface on the nozzle plate during a freeze thaw cycle of ink in the ink chamber. A method for accommodating expansion and contraction of ink during a freeze thaw cycle of ink in an ink chamber is also provided. The method includes providing a group of priming holes in a nozzle plate of the ink chamber, the group of priming holes maintaining a substantially ink free surface on the nozzle plate during the freeze thaw cycle.

摘要： A chip used for dispensing a fluid such as ink provides ink-dispensing ejectors having an ink cavity over a supporting substrate, and further provides a heater for heating the ink in the cavity. The heater can be interposed between the substrate and the ink cavity to provide direct heating of ink as it is being dispensed. Various embodiments further comprise the use of the heater structure as a temperature probe to measure the temperature of the ink in the ink cavity. Other embodiments provides a chip having both a temperature probe and a heater as separate structures interposed between the ink cavity and the substrate. Further described is a temperature probe and/or heater which traverses a majority of a width of a substrate, and surrounds each drop ejector on at least two sides.

摘要： The present application is directed to electrostatic actuators, and methods of making electrostatic actuators. In one embodiment, an electrostatic actuator of the present application comprises a first electrode and a second electrode. The second electrode is positioned in proximity to the first electrode so as to provide a gap between the first electrode and the second electrode. The first electrode is capable of being deflected toward the second electrode. A dielectric structure comprising a dielectric landing post is positioned in the gap between the first electrode and the second electrode, the dielectric structure extending over a greater surface of the gap than the landing post. The landing post protrudes out into the gap so as to limit the minimum contact spacing between the first electrode and the second electrode.
