摘要： In a computer controlled, drop-by-drop, inkjet printer, either thermal ink-jet or piezoelectric, an apparatus for dampening the vibration caused by expelling the drops of ink. The apparatus includes an inlet and an outlet flow conduit connected to the chamber from which the drops are expelled and means for sweeping the vibration out of the chamber and into one of the flow conduits. In operation, the apparatus first expels a drop of liquid from the chamber and thereby creates a region of vibration in the liquid remaining in the chamber. The flow of liquid through the chamber flushes the region of vibration out of the chamber and into the outlet flow conduit, thereby hydraulically dampening the vibration.

摘要： A printhead having reduced spray includes orifi from which ink is expelled by an ink ejector. The orifi employ an aperture at the outer surface of the orifice plate having two orthogonal dimensions with one dimension having a greater magnitude than the other. The aperture is further defined by two non-intersecting edges spaced apart at one point by a distance of the smaller of the two dimensions and spaced apart at all other points by a distance greater than the smaller dimension such that the orifi are hourglass shaped.

摘要： An ink jet print head having a substrate with an upper surface, and an ink supply conduit passing through the substrate. An array of independently addressable ink energizing elements are attached to the upper surface of the substrate. An orifice layer has a lower surface conformally connected to the upper surface of the substrate, and has an exterior surface facing away from the substrate. The orifice layer defines a plurality of firing chambers providing communication to the ink energizing elements, and each of the orifices is positioned in registration with a respective single ink energizing element. The exterior surface defines a plurality of nozzle apertures, each providing the upper terminus of a single firing chamber. Each of the firing chambers is laterally separated from all other firing chambers by a septum portion of the orifice layer.

摘要： An inkjet printer printhead is coupled to an ink source and has a plurality of ink firing chambers dimensionally defined by a barrier layer disposed between a substrate and an orifice plate. Two ink feed channels are coupled to one ink firing chamber and are dimensionally defined, in part, by the barrier layer. One of these ink feed channels has a smoothly converging wide dimension inlet at the ink source and a narrow dimension outlet at the ink firing chamber. The other ink feed channel also has a converging wide dimension inlet at the ink source and a narrow dimension outlet at the ink firing chamber but has an "S" shaped wall contour to make it asymmetrical to the first ink feed channel. An island of the barrier layer separates one ink feed channel from the other ink feed channel serving the ink firing chamber. This island has an essentially flat wall surface disposed toward the ink firing chamber.

摘要： Pillars are formed in a fully integrated thermal inkjet printhead to prevent particles from entering into a nozzle chamber along an ink refill channel. The pillars are formed after a step of applying a thin film structure to a substrate. At one step, pits are etched through the thin film structure. At another step, material for an orifice layer is deposited into the pits. At another step, a firing chamber is etched into the orifice layer. At another step, a trench is etched into the backside of the wafer in the vicinity of the filled pits. The material filling each pit is not removed and remains in place to define the respective pillars. Two or more pillars are formed within the trench for each inkjet nozzle chamber. Alternatively pillars are formed by depositing material into the underside trench and performing photoimaging processes.
