摘要： A nozzle assembly for an inkjet printhead includes a substrate assembly defining an ink inlet aperture; a nozzle comprising a wall portion extending from the substrate assembly to bound the ink inlet aperture, and a moveable crown portion from which a skirt portion depends, the wall portion and the skirt portion defining a peripheral wall of a nozzle chamber; an anchor extending from the substrate assembly; and a thermal bend actuator connected between the anchor and a lever arm. The lever arm is in turn connected to the nozzle. The thermal bend actuator, upon actuation, moves the crown and skirt portions relative to the wall portion to eject ink in the nozzle chamber out through the nozzle opening. The skirt portion and the wall portion are separated by a gap, and the wall portion is shaped with an inwardly directed lip in the vicinity of the gap, the inwardly directed lip facilitating the formation of a fluidic seal effected via surface tension across the gap.

摘要： A wide format printer includes a carrier that is mountable on a support structure of the wide format printer in an operative position with respect to a platen of the wide format printer. A number of printhead chips are positioned on the carrier, the printhead chips together incorporating at least fifty thousand nozzle arrangements. The printhead chips are positioned so that the printhead chips are capable of ejecting ink drops into a printing zone defined by the platen. Control circuitry is also positioned on the carrier and is configured to control operation of the printhead chips.

摘要： A page width printhead assembly (1) for a digital inkjet printer has a support member that can be secured in the printer, and a printhead (2) that can be mounted to the support member. The support member has a core with at least one ink reservoir (6, 7, 8 and 9) enclosed within a laminated shell (4). The materials and structure of the shell (4) and the core (5) are selected and configured so that the co-efficient of thermal expansion of the support member as a whole is substantially equal to that of the printhead (2).

摘要： A printhead assembly with an elongate support member and two or more printhead modules detachably mounted in series along the support member, the support member having a structural component for strengthening the member, and a mounting component for mounting the printhead modules; wherein, the mounting component is connected to the structural component to allow relative thermal expansion. By allowing the structural component of the support to thermally expand relative to the mounting component, the structural components can be strong, inexpensive metal despite the co-efficient of thermal expansion (CTE). Only the mounting component need approximate the CTE of the printhead chips to maintain a suitable alignment of the modules.

摘要： Provided is an alumina sintered body including not less than 99.3% by weight of Al2O3, not more than 0.25% by weight of SiO2, not more than 0.3% by weight of MgO, and not more than 0.3% by weight of CaO, and having a surface open porosity of less than 5%, and an average open pore diameter of not more than 5 nullm. This alumina sintered body is applied to at least a surface exposed to ink in an ink jet recording head structure. This suppresses the elution of glass component of the alumina sintered body into ink, thereby stabilizing ink viscosity. This also suppresses falling of grains that causes clogging of ink discharge holes.
摘要翻译：本发明提供一种氧化铝烧结体，其含有：Al2O3：99.3重量％以上，MgO：0.25重量％以下，MgO：0.3重量％以下，CaO：0.3重量％以下，CaO：表面开孔度小于5％，平均开孔直径不大于5μm。将该氧化铝烧结体施加到喷墨记录头结构中至少暴露于油墨的表面。这抑制了氧化铝烧结体的玻璃成分向油墨中的溶出，从而稳定油墨的粘度。这也抑制了导致油墨排出孔堵塞的颗粒的下降。

摘要： An inkjet printhead lid has a light opacity component and a laser light transparent component molded together in two shots in an injection molding chamber. The laser light transparency component has a periphery that extends beyond a periphery of the light opacity component on substantially all sides thereof. An inkjet printhead body laser welds to the laser light transparency component in an area between the peripheries of the two lid components. Inkjet printers for containing the printhead are also disclosed. In the molding chamber, two sources of injection molding materials inject a first and then a second mold to mold the two lid components together. One of the two sources of injection molding materials has laser light transparency characteristics while the other has light opacity characteristics. Mechanical interlocking features may also exist in both of the two lid components.

摘要： A coated substrate for a center feed printhead has a substrate, a thin film applied over the substrate, and a slot region extending through the substrate and the thin film. A slot is formed through the slot region of the coated substrate. The thin film layer coating minimizes crack formation and/or a chip count in a shelf surrounding the slot through the substrate. In one embodiment, the slot is formed mechanically. In one embodiment, a plurality of thin films is used. The slot region extends through the plurality of thin films. Any combination of thin films may be applied over the substrate. In one embodiment, the thin film is at least one of a metal film, a polymer film, and a dielectric film. In another embodiment, the thin film material is ductile and/or deposited under compression. In one embodiment, the substrate is silicon, and the thin film is an insulating layer grown from the substrate, such as field oxide. In one embodiment, the thin film is PSG. In one embodiment, the thin film is a passivation layer, such as at least one of silicon nitride and silicon carbide. In one embodiment, the thin film is a cavitation barrier layer, such as tantalum.
