Abstract: An ink jet printing head comprising a head body made from a material having high specific stiffness and the head body includes an ink passage which is kept small to retain the high body stiffness. The ink passage comprises a narrow slot connected with internal holes in the body which lead to ink inlet and exit ports. A nozzle plate having a plurality of orifices is fixed to the front of the head body and a piezoelectric crystal is fixed to the back of the head body. The piezoelectric crystal is kept thin compared to the head thickness, typically on the order of 1/20 to 1/30 of the body thickness, so that the effect of the crystal on the resonant characteristics of the assembly is kept small. The ink jet head provides a plurality of columns or jets of ink which are excited in such a way as to break up into uniformly and equally spaced drops at a fixed distance from the nozzle plate containing the orifices which produce the jets.

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: 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: A resistive ribbon thermal transfer printer has a thermal print head (18) movable across a record medium (12), and a ribbon (10) which passes between the print head and record medium from a supply reel (16) to a take-up reel (30). A selectively rotatable colour transfer device (42) applies one of four colours, depending on its angular position, to the fusible layer on the ribbon, between the supply reel and the print head.

Abstract: This printing apparatus and technique incorporates a color transfer station to impart a desired color to a fusible ink layer on a ribbon. The color transfer station is located between a supply reel providing the ribbon for printing, and the location where actual printing occurs. This color transfer technique is particularly suitable for use in resistive ribbon thermal transfer printing, where economical use of the ribbon is mandatory. The structure for transferring color to the ink layer of the ribbon utilizes wicks, felt-coated rollers, nozzles, etc., to being a selected colorant solution into contact with the ink layer of the ribbon, in accordance with the color desired for printing.
