Abstract: By advancing a plurality of independent layers or profiles onto a rotating mandrel, and continuously bonding the layers or profiles together, an elongated, hollow, large diameter, multi-component and/or multi-layer tube or conduit is achieved. A wide variety of various materials, forms, profiles, composites, and components can be employed to produce the desired multi-component/multi-layer tube or conduit of the present invention. In this way, the multi-component and/or multi-layer tube or conduit is constructed possessing specific physical and structural attributes particularly suited to the needs of one or more industries or technological areas. As a result, prior art expensive manufacturing methods are completely eliminated and an effective, cost-efficient, multi-component/multi-layer tube or conduit having precisely desired requirements is realized.

Abstract: A fluid ejecting device and method of forming same are provided. The fluid ejecting device includes a substrate having a first surface and a second surface located opposite the first surface. A nozzle plate is formed over the first surface of the substrate. The nozzle plate has a nozzle through which fluid is ejected. A drop forming mechanism is situated at the periphery of the nozzle. A fluid chamber is in fluid communication with the nozzle and has a first wall and a second wall with the first wall and the second wall being positioned at an angle relative to each other. A fluid delivery channel is formed in the substrate and extends from the second surface of the substrate to the fluid chamber. The fluid delivery channel is in fluid communication with the fluid chamber. A source of fluid impedance comprises a physical structure located between the nozzle and the fluid delivery channel.

Abstract: A fluid ejection device and a printhead including one or more such fluid ejection devices are provided. The fluid ejection device includes a substrate having a first nozzle array and a second nozzle array, each array having a plurality of nozzles and being arranged along a first direction, the first nozzle array being arranged spaced apart in a second direction from the second nozzle array. A first fluid delivery pathway is in fluid communication with the first nozzle array, and a second fluid delivery pathway is in fluid communication with the second nozzle array. Nozzles of the first nozzle array have a first opening area and are arranged along the first nozzle array at a pitch P. Nozzles of the second nozzle array have a second opening area, the second opening area being less than the first opening area. At least one nozzle of the second array is arranged offset in the first direction from at least one nozzle of the first array by a distance which is less than pitch P.

Abstract: A method of etching a substrate and an article(s) formed using the method are provided. The method includes providing a substrate; coating a region of the substrate with a temporary material having properties that enable the temporary material to remain substantially intact during subsequent processing and enable the temporary material to be removed by a subsequent process that allows the substrate to remain substantially unaltered; removing a portion of the substrate to form a feature, at least some of the removed portion of the substrate overlapping at least a portion of the coated region of the substrate while allowing the temporary material substantially intact; and removing the temporary material while allowing the substrate to remain substantially unaltered.

Abstract: A printhead has a fluid chamber having an orifice, an associated fluid drop forming mechanism, and an associated fluid drop steering device. The fluid drop forming mechanism is operable to apply to fluid present in the fluid chamber energy sufficient to cause a fluid drop to be ejected from the orifice. The fluid drop steering device is operable to optionally apply to fluid present in the fluid chamber energy insufficient to cause drop formation prior to the fluid being ejected from the orifice. The fluid drop steering device is distinct from the fluid drop forming mechanism.
