摘要： According to one embodiment of the present invention, a print head comprises a print head body defining an interior chamber and an orifice plate. The orifice plate has an outer surface and further defines a cleaning fluid orifice through the orifice plate for conducting a flow of a cleaning fluid through the cleaning fluid orifice and onto an outer surface of said orifice plate. The orifice plate also defines a drain orifice for conducting a flow of cleaning fluid from the surface to the interior chamber. A supply of pressurized cleaning fluid is disposed in said cavity and connected to the cleaning fluid passageway. During cleaning operations, the fluid flow system defines a flow of a cleaning fluid from the passageway and onto said outer surface. The drain orifice receives cleaning fluid from the outer surface and channels the cleaning fluid into the fluid return.

摘要： The present invention comprises a self-cleaning print head having an orifice plate defining an ink jet orifice, cleaning orifice and drain orifice. The orifice plate further defines an outer surface between the orifices. The print head has a source of pressurized cleaning fluid connected to the cleaning orifice and a fluid return connected to the drain orifice for storing used cleaning fluid. During cleaning operations, the source of pressurized cleaning fluid causes cleaning fluid to flow from the cleaning orifice, and the cleaning orifice directs the flow of cleaning fluid across the outer surface and the ink jet orifice and into the drain orifice.

摘要： A self-cleaning printer includes a print head having a surface that is susceptible to a contaminate build up. A cleaning liquid containing a concentration of macroscopic cleaning particles is flowed in frictive contact with the contaminate such that a combined effect of frictive force and hydrodynamic shearing force acting on the contaminate effectively removes the contaminate from the surface. Preferably, the cleaning particles are adapted to attach to the contaminate. They may include polymeric beads such as polystyrene spheres. The cleaning particles preferably have surfaces to which polymeric chains are attached, the polymeric chains having end groups which adhere to the contaminate.

摘要： The present invention resides in a self-cleaning printer with a print head having an orifice plate defining an ink jet orifice, a cleaning orifice and a drain orifice. The orifice plate further defines an outer surface between the orifices. A source of pressurized cleaning fluid is connected to the cleaning orifice and a fluid return is connected to the drain orifice for storing used cleaning fluid. A cleaning surface is disposed adjacent to and separate from the outer surface to define a capillary fluid flow path from the cleaning orifice across the ink jet orifice and to the drain orifice. During cleaning, the source of pressurized cleaning fluid discharges a flow of a cleaning fluid into the capillary fluid flow path and pressurized cleaning fluid from the capillary flow path passes through the drain orifice and into the fluid return.

摘要： A pump(10) for pumping various primary fluids includes a body(100) having a primary fluid channel(110) defined therein, and a primary fluid supply is coupled to the primary fluid channel to supply a primary fluid to the primary fluid channel. A mechanism(130/132) is provided for introducing a secondary fluid to an interface region of the primary fluid channel to thereby define a fluid interface between the primary fluid and the secondary dry fluid in the interface region. An energy delivery(150/160) device delivers energy to the interface region to create a thermal gradient along the fluid interface. The thermal gradient results in a surface tension gradient along the interface. The primary fluid will move to compensate for the surface tension gradient.

摘要： Drop-on-demand ink jet printer capable of directional control of ink drop ejection and method of assembling the method. The method comprises a print head body having an ink ejection orifice adapted to poise an ink meniscus thereat about a center axis passing through the orifice. A deflector is coupled to the print head body and is adapted to be in communication with the poised meniscus for lowering surface tension of a region of the poised meniscus. The poised meniscus deflects away from the region of lower surface tension and away from the center axis to define a deflected meniscus, whereby an ink drop separated from the deflected meniscus travels at an angle with respect to the center axis, so that the ink drop can strike a receiver at any one of a plurality of predetermined locations on a print line.

摘要： Methods and apparatuses are provided for depositing a material on a surface. In accordance with the method a stream of a component material is formed having formed printing and non-printing droplets and satellite droplets of the material. The stream is directed at the surface. A deflecting energy is applied to separate printing droplets from non-printing droplets in the stream, so that only printing droplets travel to the surface. The deflecting energy is adapted to direct non-printing droplets for non-printing drop collection, and to direct at least a portion of the satellite droplets to be controlled in a manner adapted to prevent the material in the satellite droplets from reaching the surface, so that less than all of the material in the satellite droplets reaches the surface. Articles are also provided having limited satellite material.
