摘要： A drop-on-demand liquid emission device, such as for example an ink jet printer, includes a member movable through a path for driving liquid from the device, wherein the speed at which the member moves is reduced over the time period that liquid is being expelled. During that time period, a portion of the liquid flows through a passage away from the nozzle orifice. According to a feature of the present invention, a variable flow restrictor increases the resistance to flow through the passage during the time period that liquid is being expelled; thereby tending to compensate for the reduction of the liquid-expulsion force over the time period. The result is a reduction of undesirable satellite droplets following a main drop.

摘要： A drop emission device includes a chamber having a nozzle orifice through which a drop of liquid can be emitted. A deformable electrode is associated with the chamber such that movement of the electrode in a first direction increases the chamber's volume and movement of the electrode in a second direction decreases the chamber's volume to emit a drop through the nozzle orifice. A fixed electrode opposes to the deformable electrode to define a second chamber there between such that control of relative voltage differences between the deformable and the fixed electrodes selectively moves the deformable electrode in the first or second directions. The variable volume is vented to a source of dielectric material through an opening in the fixed electrode. The ratio of the cross-sectional area of the opening to the perimeter of the opening is greater than 0.5 μm, and is preferably about 5 μm.

摘要： A continuous ink jet print head is formed using a combination of traditional CMOS technology to form the various controlling electrical circuits on a silicon substrate having insulating layer(s) which provide electrical connections and a MEMS technology for forming nozzle openings. A blocking structure is formed in the insulating layer(s) between a first ink channel formed in the silicon substrate and a second ink channel formed in the insulating layer(s). The blocking structure causes ink to flow around the blocking structure and thereby develop lateral flow components to the liquid entering the second channel so that, for droplets selected for printing, as the stream of droplets emanates from the bore of the nozzle, there is provided a reduced amount of heat needed for operating a heating element adjacent each nozzle opening.

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.

摘要： A printer having mechanically-assisted ink droplet separation and method of using same, for separating an ink meniscus from an ink nozzle orifice while clearing-away particulate matter from about the orifice. In a preferred embodiment of the invention, a heater surrounds an orifice formed by the nozzle, the orifice having an ink meniscus residing therein. As the heater heats the ink meniscus, surface tension of the ink meniscus decreases, thereby causing the ink meniscus to extend outwardly from the orifice to define an extended ink meniscus. A cutter, which is disposed near the orifice, includes a plate member disposed opposite an outside surface of the nozzle so as to define a passage between the outside surface and the plate member. The plate member has an opening aligned with the orifice and in communication with the passage. A gas pressure regulator in communication with the passage supplies pressurized gas into the passage, which gas flows along the passage an through the opening. As the gas flows through the opening, it impinges the extended ink meniscus to separate the extended ink meniscus from the orifice. As the extended ink meniscus separates from the orifice, it forms an ink droplet that travels to a receiver medium, so that an ink spot is placed onto the receiver medium. Moreover, as the gas flows through the opening, the gas clears-away particulate matter from about the orifice.
