Patent Number | Published Abstract |
WO 2007113554 | Droplet deposition apparatus comprising an array of fluid chambers defined by a pair of opposing chamber walls, and in fluid communication with a nozzle for droplet ejection therefrom; a cover member is joined to the edges of the chamber walls and thus seals one side of the chambers. The cover member has a ratio of cover thickness to chamber wall separation less than or equal to 1:1. |
WO 2007007074 | In an ink jet printhead have an elongate ink chamber and a nozzle at one end, a continuous flow of ink is provided through a high impedance channel communicating with the chamber close to the nozzle. Ink is ejected through the nozzle by generating longitudinal acoustic waves in the fluid chamber. A high velocity ink flow into the chamber from the channel sweeps away from the nozzle debris or bubbles that might otherwise block the nozzle. |
WO 0038928 | Droplet deposition apparatus comprises an array of fluid chambers, each chamber communicating with an orifice for droplet ejection, a common fluid inlet manifold and a common fluid outlet manifold, and means for generating a fluid flow into the inlet manifold, though each chamber in the array and into the outlet manifold, the fluid flow through each chamber being sufficient to prevent foreign bodies in the fluid from lodging in the orifice. Each chamber is associated with means for effecting droplet ejection from the orifice simultaneously with the fluid flow through the chamber. The resistance to flow of one of the inlet and outlet manifolds is chosen such that the pressure at a fluid inlet to any chamber in the array varies between any two chambers by an amount less than that which would give rise to significant differences in droplet ejection properties between these two chambers. |
WO 0029217 | An ink jet printhead has a body of PZT bonded to a base plate. Channels cut in the PZT form ink chambers which are actuated by applying voltages to electrodes on surfaces of the chambers. The base plate also carries IC's which contain the drive circuitry for actuating the ink chambers. To ensure reliable electrical interconnection between the chamber electrodes and the IC's, the electrodes and conducting tracks on the base plate are formed in a single step by depositing a conductive layer over both the PZT body and the base plate. The necessary pattern of electrodes and tracks can be achieved by masking or by selective material of conductive material. |
WO 0112442 | A component for a drop-on-demand piezoelectric printhead is formed from a block of piezoelectric material and a substrate. The block of piezoelectric material has grooves formed in its lower surface and is attached to the substrate using an adhesive that is applied in sufficient quantity such that adhesive enters the grooves cut into the piezoelectric material. Upper grooves are sawn into the piezoelectric material through to the glue-filled lower channels in order to form ejection channels, the walls of which are separated from one another by means of a glue fillet. |
WO 03022585 | An ink jet printer with ink flowing through an ink chamber and over an ink ejection port leading to a nozzle has a deflection surface such as a chamfer at the junction of the chamber and the ejection port to inhibit debris from entering the port. |
WO 9852763 | Droplet deposition apparatus comprising first and second channels, one end of each channel communicating with a single, common supply chamber for supply of droplet liquid and the respective other ends of the first and second channels each communicating with a respective further supply chamber for supply of droplet liquid; each of said first and second channels having an opening for ejection of droplets there from; and actuator means being associated with each channel for effecting the ejection of droplets. |
WO 0108888 | Droplet deposition apparatus comprising an elongated chamber having a nozzle through which in operation droplets of liquid are ejected from the chamber for deposition, means for varying the pressure of liquid in the chamber by varying the volume thereof to effect ejection of said droplets and means for causing a flow of liquid in the chamber in addition to that necessary to replenish the ejected droplets, the flow passing across said nozzle to clean it. |
WO 0149493 | Droplet deposition apparatus comprises at least one droplet ejection unit comprising a plurality of fluid channels disposed side by side in a row, actuator means, and a plurality of nozzles, said actuator means being actuable to eject a droplet of fluid from a fluid channel through a respective nozzle; a support member for said at least one droplet ejection unit; a first conduit extending along said row and to one side of both said support member and said at least one droplet ejection unit for conveying droplet fluid to each of the fluid channels of said at least one droplet ejection unit; and a second conduit extending along said row and to the other side of both said support member and said at least one droplet ejection unit for receiving droplet fluid from each of the fluid channels of said at least one droplet ejection unit. |
WO 03022587 | A hollow cylindrical support for a plurality of flow-through inkjet print heads has two folded wall sections cooperating to define elongate inlet and outlet ink manifolds, one wall section being thermally conducting so as to promote heat transfer along the length of the support, the other wall section being thermally insulating so as to inhibit heat transfer between the inlet and outlet manifolds. The thermally insulating section serves to trap a boundary layer of fluid, for example in a cavity wall or cellular material. |
