摘要： Methods and systems for forming slotted substrates are described. In one exemplary embodiment, a substrate has a thickness defined by a first surface and a generally opposing second surface. The substrate has a fluid-feed slot extending between the first surface and the second surface with the fluid-feed slot being defined, at least in part, by a central portion and one or more capillary channels in fluid flowing relation to the central portion.

摘要： Described herein is a monolithic printhead formed using integrated circuit techniques. Thin film layers, including ink ejection elements, are formed on a top surface of a silicon substrate. The various layers are etched to provide conductive leads to the ink ejection elements. At least one ink feed hole is formed through the thin film layers for each ink ejection chamber. A trench is etched in the bottom surface of the substrate so that ink can flow into the trench and into each ink ejection chamber through the ink feed holes formed in the thin film layers. The trench completely etches away portions of the substrate near the ink feed holes so that the thin film layers form a shelf in the vicinity of the ink feed holes. In one embodiment, the shelf supports the ink ejection elements. An orifice layer is formed on the top surface of the thin film layers to define the nozzles and ink ejection chambers.

摘要： A bubble valve that comprises a liquid delivery channel and a localized heating arrangement. The liquid delivery channel includes an upstream portion and a constriction downstream of the upstream portion. The constriction has a smaller cross-sectional area than the upstream portion. The localized heating arrangement is located in the liquid delivery channel and generates heat to nucleate and enlarge a bubble in the liquid. The constriction is shaped to form a seal with the bubble. The localized heating arrangement additionally generates heat to move the bubble relative to the constriction to control the flow of the liquid. A pressure regulator that comprises a liquid delivery channel connected to a liquid outlet, a sensor located adjacent the liquid outlet, a controller that operates in response to the sensor and a localized heating arrangement. The liquid delivery channel includes an upstream portion, and a constriction located between the upstream portion and the liquid outlet. The constriction has a smaller cross-sectional area than the upstream portion. The localized heating arrangement is located in the liquid delivery channel and generates heat in response to the controller to nucleate and enlarge a bubble in the liquid. The constriction is shaped to form a seal with the bubble. The localized heating arrangement additionally generates heat to move the bubble relative to the constriction to control the flow of the liquid to the liquid outlet.

摘要： An inkjet printing device is arranged to employ a first set of multiple nozzle drop generators activated by a first address signal and a second set of multiple nozzle drop generators activated by a second address signal. The multiple nozzles of each drop generator of the first set are arranged in a predetermined geometric pattern, each of which encompasses at least one nozzle of a drop generator of the second set. The ink ejectors of one drop generator of the first drop generator set are arranged in subgroups, one subgroup of which shares a switched power return with one subgroup of ink ejectors of one drop generator of the second drop generator set.

摘要： A printhead for ejecting fluid has a nozzle on a first surface and a fluid feed channel defined within a second surface. The printhead includes an aggregate of thin-film layers, a portion of which is exposed by the fluid feed channel. The aggregate of thin-film layers contains at least one energy dissipation element suspended over the fluid feed channel. A heat spreader is mesially interposed within the aggregate of thin-film layers. The heat spreader proximally abuts to the energy dissipation element and extends from the energy dissipation element to extend past the fluid feed channel definition. The heat spreader is capable of dissipating heat from the energy dissipation element to a portion of the first surface of the printhead.

摘要： The described embodiments relate to methods and systems for forming slots in a substrate. In one exemplary embodiment, a slot is formed in a substrate that has first and second opposing surfaces. A first trench is dry etched through the first surface of the substrate. A second trench is created through the second surface of the substrate effective to form, in combination with the first trench, a slot. At least a portion of the slot passes entirely through the substrate, and the maximum width of the slot is less than or equal to about 50 of the thickness of the substrate.
