Patent number: 8591008Abstract: A printer includes a printhead die including liquid ejectors separated by walls. Each liquid ejector includes a nozzle orifice and an associated drop forming mechanism. First and second liquid feed channels, extending in opposite directions, are in fluid communication with each liquid ejector. A liquid inlet includes a plurality of first and second segments in fluid communication with the first liquid feed channels and the second liquid feed channels, respectively. The first and second segments are located on opposite sides of the nozzle orifice. For a given liquid ejector, both of the first and second segments are directly in line with the liquid ejector.

Patent number: 7183216Abstract: A thermal oxidation process is used to fill trenches with an oxide; however, the oxidation process consumes some of the silicon. The embodiments herein advantageously apply this tendency for the oxidation process to consume silicon so as to convert all the silicon substrate material between the multiple trenches into an oxide. Therefore, because all of the silicon between the multiple trenches is consumed by the oxidation process, the multiple smaller trenches are combined into a single larger trench filled with the oxide.Type: GrantFiled: May 18, 2005Date of Patent: February 27, 2007Assignee: Xerox CorporationInventors: Cathie J. Burke, Peter M. Gulvin
