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.

摘要： A technique for controlling the abrasive jet machining process to drill an ink feed slot through an ink jet printhead substrate. The approach results in a relatively even slot edge adjacent to channels that supply the ink-droplet firing chambers of the printhead. The evenness of the edge reduces the tolerances required for designing the channels and other printhead components, thus permitting the construction of printheads with increased droplet ejection frequency. The printhead size is correspondingly reduced.

摘要： A method of delivering abrasive particulate material under pressure from a storage container adapted to contain the abrasive particulate material therein includes communicating an inlet valve with an inlet opening of the storage container and supplying a first gas, regulated to a first predetermined pressure, to the inlet valve. The first gas is released through the inlet valve and into the storage container, and a quantity of the abrasive particulate material is discharged through an outlet opening of the storage container to an output junction. In addition a second gas, regulated to a second predetermined pressure, is supplied to the output junction. As such, a pressurized supply of the abrasive particulate material is formed and delivered through the output junction.

摘要： A method of forming a slotted substrate that includes patterning a thin film over a substrate so that at least a portion of the substrate within a slot region is not covered by the thin film. In addition, a slot is formed in the substrate through the slot region that extends through the substrate and the thin film, wherein a chip count in a shelf surrounding the slot is minimized when the slot is formed in the substrate through the thin film in the slot region.

摘要： A pressurized delivery system for abrasive particulate material includes a storage container adapted to contain the abrasive particulate material therein, an input pressure line adapted to communicate with a pressurized source, and a fluidizing pressure line communicating with the input pressure line and an inlet opening in the storage container. A back-pressure pressure line communicates with an unoccupied portion of the storage container and an output pressure line. The output pressure line, into which the abrasive particulate material is fed from the storage container, communicates with the input pressure line, the back-pressure pressure line, and an outlet opening of storage container. During operation, pressurized gas is released through the inlet opening and into the storage container such that the abrasive particulate material adjacent the outlet opening is fluidized and maintained flowable so as to achieve consistent flow of the abrasive particulate material through the outlet opening.
