Abstract: STAGGERED NOZZLE ARRAY of The Disclosure A jet printer includes a nozzle plate having at least two rows of nozzles, with the nozzles in one row being laterally staggered with respect to the nozzles in another row. The jets emanating from the respective rows of nozzles are directed in non-parallel trajectories to form at least a portion of a single line of dots at a time on a printing medium, with the jets from a given row forming non-adjacent dots on the printing medium. In practice, the nozzle plate is comprised of a semiconductor substrate, for example silicon, with the exit aperture of each of the nozzles in at least one row being axially misaligned with respect to the longitudinal center axis of their respective entrance apertures, resulting in a non-normal jet trajectory with respect to the plane of the nozzle plate.

Abstract: METHOD AND APPARATUS FOR ACOUSTICALLY SYNCHRONIZING DROP FORMATION IN AN INK JET ARRAY An ink jet synchronization scheme, wherein the drop formation of respective streams in an ink jet array are synchronized acoustically by individual acoustic fiber inputs to each of the streams. The acoustic fibers are attached to grooves adjacent each of the nozzles, with acoustic isolation being provided between the fiber and the nozzle substrate to prevent direct excitation of the substrate. This prevents the occurrence of resonance within the nozzle plate. Alternatively, acoustic isolation is achieved by mounting the synchronization structure separate from the nozzle plate. For example, the acoustic fibers are attached to the charge electrode structure, or are attached to a support structure intermediate the nozzle plate and the charge electrode structure. The acoustic energy inputs to the fibers are independently controlled as is required for certain printing schemes or are made identical as is normally the case.

Abstract: 1519103 Selective printing INTERNATIONAL BUSINESS MACHINES CORP 18 Nov 1976 [31 Dec 1975] 48201/76 Heading B6F Ink jet printer has pair of parallel rows of nozzles offset in the direction of their length. The jets issuing from each row are directed to different sets of non-adjacent dot positions in a row 12 and the trajectories of the jets emanating from one row of nozzles are not parallel to those of the jets emanating from the other row. The nozzles may be produced by anisotropic etching of a semi-conductor chip.

Abstract: In an ink jet printing system, a single nozzle or an array of nozzles are etched in a semiconductor material such as silicon. Each nozzle has polygonal or N-sided entrance and exit apertures of different cross-sectional area. Preferably, the nozzle is in the shape of a truncated pyramid with the entrance and exit apertures being substantially square in cross-section. The corners of the apertures and wall interfaces may be rounded to reduce stress concentrations.

Abstract: METHOD AND APPARATUS FOR CONTROLLING THE FORMATION AND SHAPE OF DROPLETS IN AN INK JET STREAM Method and apparatus is described for controlling the formation and shape droplets in an ink jet stream. The continuous portion of the stream is illuminated with a radiant energy source such as a laser. The surface wave profile produced by illuminating the stream is sensed to provide the fundamental and harmonic frequency components thereof. A perturbation drive signal, the amplitude and relative phase of which is a function of the sensed frequency components, is provided for controlling the formation and shape of the droplets.

Abstract: JET NOZZLE STRUCTURE FOR ELECTROHYDRODYNAMIC DROPLET FORMATION AND INK JET PRINTING SYSTEM THEREWITH The practice of this disclosure obtains a monolithic structure useful for electrohydrodynamically synchronizing the formation of droplets in a jet stream exiting from a jet nozzle. The monolithic structure is primarily adaptable for ink jet printing. The jet nozzle structure provided by the practice of this disclosure includes a jet nozzle design in a crystalline semiconductor block, e.g., of silicon (Si), germanium (Ge) or gallium arsenide (GaAs), with an electrode structure which is integrally incorporated therewith whereby a variable electric field is established proximate to the orifice of the jet nozzle structure. The electric field electrohydrodynamically perturbs the jet stream emitting from the jet nozzle structure so that formation of drops in the jet stream is controllably achieved, e.g. synchronously when the variable electric field is oscillating with a given periodicity. In an exemplary practice of this disclosure, a conductive region is integrally incorporated with a jet nozzle design formed from a block or wafer or substrate of single crystalline silicon either in or on said nozzle whereby a varying electric field is established proximate to the orifice such that the jet stream is temporally and spatially influenced electrohydrodynamically by said electric field. For a particular design of the conductive region, a doped Si region in the Si substrate is utilized therefor. In the fabrication of a particular type of jet nozzle design, which utilizes a block of single crystalline silicon during the fabrication of the jet nozzle, there is included a diffused p+ region and an insulation layer which is formed either unitary therewith, e.g., by oxidation, or is formed ancillary thereto by deposition of an insulation layer. When a synchronizing signal is applied to said p+ silicon layer, an oscillating electric field is established proximate to the orifice of the jet nozzle. There is achieved by the practice of this disclosure a monolithic device for ink jet printing with a plurality of jets which are controllable either independently or cooperatively through appropriate integrated silicon semi-conductor circuitry.
