    摘要: A novel method of fabricating the channel ends of an ink jet printhead: lithographically fabricating channels in photopolymer having the channel end blocked by a thin layer of photopolymer; sandwiching the photopolymer between two parallel substrates, one of which has an actuator for each channel; dicing through the substrates on a line perpendicular to the channels and leaving the channels and solid wall at the end of the channels intact; optionally coating the diced face including the polymer wall blocking the channel ends with a hydrophobic material; and forming nozzles in the end of the channels by laser ablating through the polymer layer at the end of the channel. Forming the nozzles after dicing and the optional coating prevents contamination of the interior of the printhead. The nozzles can be recessed from the diced edges of the substrate. Photolithographic formation of the end of the channel insures an accurate distance is maintained between the nozzle and the actuator. Improved jetting stability, directionality of the ejected drops, and drop size result from this novel fabrication method.

    摘要: Disclosed are adhesive coating compositions containing a metal peroxide for producing clear colorless adhesive coatings on substrates, particularly micro particulate substrates. In one preferred embodiment the nanoparticle coatings are chemically active and function at a high level of efficiency due to the high total surface area of the micro particulate substrate. Also disclosed are coated substrates and compositions having nanoparticles bound to a substrate by the coating compositions.

    摘要: A portable water-purification system includes a container for holding a liquid and an ultraviolet light source configured for immersion in the liquid. The ultraviolet light source is a straight low-cost tube controlled by electronic circuitry for providing hot-cathode striking at a relatively low voltage using a fly-back inductor. The operation of the water purification system is controlled by a micro-controller within the electronic circuitry.

    摘要: Plural film layers are disposed on a substrate. Each film layer has regions devoid of film material, thus forming film layer cavity openings. Each film layer has its cavities arranged to provide fluid coupling with its adjacent film layer or layers. The film layer cavities form a traverse channel coupling the top and bottom film layers and also one or more lateral channels coupling cavity openings in the top film layer. The film layer traverse channel couples with a substrate channel that extends from the substrate top surface to one or more of its other surfaces. A device such as a fluid dispenser, fluid ejector, sensor or bioprocessing device is disposed on the top film layer and fluidly coupled to the plural film layers traverse and lateral channels. The traverse channel and the one or more lateral channels are arranged to transport or flow one or more fluids.
