20090219349 | DIAPHRAGM PLATE WITH PARTIALLY-ETCHED PORT - A printhead assembly that includes a partially-etched port structured to be opened by application of pressure to the port area, one or more leaflets being depressed into an internal chamber communicating with the open port. | 09-03-2009 |
20090244182 | INJET JET STACK EXTERNAL MANIFOLD - An inkjet external ink manifold is provided that allows for use of a jet stack that does not internally contain ink manifolds. The external ink manifold has a manifold body that includes one or more ink manifold chambers and includes ports arranged to connect the chambers to one or more ink reservoirs. The external ink manifold further includes an adhesive layer overlying and sealing the ink manifold chambers. The adhesive layer includes a plurality of ports arranged to connect the external ink manifold chambers to the jet stack. | 10-01-2009 |
20100033532 | SURFACE CLEANING USING A FILAMENT - A cleaning apparatus for use in an inkjet imaging device comprises a wiper filament carriage; a wiper filament; and a filament tensioning system supported by the wiper filament carriage. The filament tensioning system is operably coupled to opposing ends of the wiper filament and configured to tension the wiper filament to form a substantially straight line therebetween. | 02-11-2010 |
20100141703 | METHOD FOR LASER DRILLING FLUID PORTS IN MULTIPLE LAYERS - A method includes attaching multiple layers to a back side of at least a portion of a fluid dispensing subassembly having at least one inlet port to form a fluid dispensing assembly, aligning a laser to a region of the fluid dispensing assembly, the region corresponding to the inlet port, and forming at least one hole in the region using a laser, the hole completing a path through the layers to the inlet port. A fluid dispensing assembly has a fluid dispensing subassembly having at least one inlet port, a fluid manifold having at least one outlet, at least two layers between the fluid dispensing subassembly and the manifold, and a fluid path in the at least two layers between the outlet and the inlet port, the fluid path having smooth walls and substantially uniform width. | 06-10-2010 |
20100294545 | INTERCONNECT FOR TIGHTLY PACKED ARRAYS WITH FLEX CIRCUIT - Exemplary embodiments provide interconnects and methods for interconnecting an electrical device array with a flexible circuit by filling a chemically-etched or laser-ablated integral stencil with conductive materials | 11-25-2010 |
20110298871 | ELECTRICAL INTERCONNECT USING EMBOSSED CONTACTS ON A FLEX CIRCUIT - A print head has a jet stack having an array of jets, an array of transducers arranged on the jet stack such that each transducer corresponds to a jet in the array of jets, and a flexible circuit substrate arranged adjacent the array of transducers such that contact pads on the flexible circuit substrate make electrical connection to at least some of the array of transducers, the flexible circuit substrate being embossed so that the contact pads extend out of a plane of the flexible circuit substrate. A method of manufacturing a print head includes forming a jet stack having an array of jets, arranging an array of transducers on the jet stack such that each transducer in the array of transducers corresponds to each jet in the array of jets, embossing a flexible circuit substrate having contact pads such that the contact pads extend out of a plane of the flexible circuit substrate, and arranging the flexible circuit substrate such that the contact pads electrically connect to at least some of the transducers in the array of transducers. | 12-08-2011 |
