    摘要: A method of fabricating a printhead having a hydrophobic ink ejection face, the method comprising the steps of: (a) providing a partially-fabricated printhead comprising a plurality of nozzle chambers and a nozzle plate having relatively hydrophilic nozzle surface, the nozzle surface at least partially defining the ink ejection face of the printhead; (b) defining a plurality of nozzle openings in the nozzle plate; (c) depositing a hydrophobic polymeric layer onto the nozzle surface; (d) depositing a protective metal film onto the polymeric layer; (e) subjecting the printhead to an oxidizing plasma; and (f) removing the protective metal film, thereby providing a printhead having a relatively hydrophobic ink ejection face. Step (b) may be performed immediately after any of steps (a), (c) or (d).

    摘要: A thermal bend actuator comprising: (a) a pair of electrical contacts positioned at one end of the actuator; (b) an active beam connected to the electrical contacts and extending longitudinally away from the contacts, the active beam defining a bent current flow path between the contacts; and (c) a passive beam fused to the active beam. When a current is passed through the active beam, the active beam heats and expands relative to the passive beam, resulting in bending of the actuator. The active beam comprises a resistive heating bar having a relatively smaller cross-sectional area than any other part of the current flow path. Heating of the active beam is concentrated in the heating bar.

    摘要: A thermal bend actuator comprises an active beam for connection to drive circuitry and a passive beam mechanically cooperating with the active beam. When a current is passed through the active beam, the active beam expands relative to the passive beam resulting in bending of the actuator. The passive beam is comprised of first and second layers, and the second layer is sandwiched between the first layer and the active beam. The second layer is relatively more thermally insulating than the first layer.

    摘要: A thermal bend actuator, having a plurality of elements, is provided. The actuator comprises a first active element for connection to drive circuitry and a second passive element mechanically cooperating with the first element. When a current is passed through the first element, the first element expands relative to the second element, resulting in bending of the actuator. One of the plurality of elements is comprised of a porous material.
