摘要： A liquid emission device includes a chamber having a nozzle orifice. Separately addressable dual electrodes are positioned on opposite sides of a central electrode. The three electrodes are aligned with the nozzle orifice. A rigid electrically insulating coupler connects the two addressable electrodes. To eject a drop, an electrostatic charge is applied to the addressable electrode nearest to the nozzle orifice, which pulls that electrode away from the orifice, drawing liquid into the expanding chamber. The other addressable electrode moves in conjunction, storing potential energy in the system. Subsequently the addressable electrode nearest to the nozzle is de-energized and the other addressable electrode is energized, causing the other electrode to be pulled toward the central electrode in conjunction with the release of the stored elastic potential energy. This action pressurizes the liquid in the chamber behind the nozzle orifice, causing a drop to be ejected from the nozzle orifice.

摘要： An electrostrictive micro-valve is provided for modulating a fluid flow through a cannula or other narrow liquid conduit. The micro-valve includes a valve body having a passageway for conducting a flow of fluid, a valve element formed from a piece of viscoelastic material and disposed in the passageway, and a control assembly coupled to the viscoelastic material for electrostatically controlling the shape of the material to open or close the passageway. The valve element has a flat lower side connected to an inner wall of the passage of the valve body, and an upper side which faces an opposing wall within the passageway. The control assembly includes a pair of electrodes disposed over the upper and lower sides of the valve element. The electrode facing the lower side of the element is patterned so that localized electrostatic forces are generated across the viscoelastic material when a voltage is applied across both electrodes. Localized electrostatic forces generate a sinusoidal ripple throughout the viscoelastic material forming the valve element whose peak portions act as obstructions throughout the valve body that partially or completely obstruct a fluid flow.

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： A continuous ink jet print head is formed of a silicon substrate that includes integrated circuits formed therein for controlling operation of the print head. An insulating layer or layers overlies the silicon substrate and has a series or an array of nozzle openings or bores formed therein along the length of the substrate and each nozzle opening is formed in a recess in the insulating layer or layers by a material depletion process such as etching. The process of etching defines the nozzle openings at locations where heater elements are formed in the insulating layer or layers during a conventional CMOS processing of the integrated circuits. The print head structure thereby provides for minimal post processing of the print head after the completion of the CMOS processing.
