US Classification:

400323, 400 29, 400691

Abstract:

The invention is directed to an apparatus for applying at least one graphic to at least one surface, comprising a portable scaffolding system that may be telescoped to accommodate a length and a width of the surface; a host device for receiving at least one head attachment; and a computing device for incrementally moving the host device along the width and the length of the surface and for controlling a distance between the host device and the surface. The invention is also directed to a computer-implemented method for applying at least one graphic to at least one surface, comprising receiving at least one selected graphic; receiving data for mapping the surface; communicating instructions to a horizontal drive means for moving a print head across a width of the surface; communicating instructions to a vertical drive means for moving the print head along a length of the surface; communicating instructions to a host drive means for moving the print head toward and away from the surface; and communicating instructions to the print head for applying at least one colorant to the surface.

Appl. No.:

6/562302

Inventors:

Francis C. Lee - San Jose CA
Ross N. Mills - Boulder CO
Robert N. Payne - San Jose CA
Frank E. Talke - Morgan Hill CA

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G01D 1518

US Classification:

346140R

Abstract:

An ink jet drop-on-demand printing system comprising an ink jet print head having an ink cavity supplied with a suitable ink. An electromechanical transducer is mounted in mechanical communication with the ink cavity, and a source of electrical signals is provided to selectively actuate the transducer to produce an ink drop of a selected size. To produce ink drops of a selected size the source of electrical signals produces one or more electrical drive signals each separated by a fixed time delay which is short with respect to the drop-on-demand drop production rate. Each electrical drive signal ejects a predetermined volume of ink and all the volumes of ink merge to form a single drop prior to the time the ink drops reach the print medium for printing.

International Classification:

B41J 2065
B41J 2205

US Classification:

347 11

Abstract:

In an electrostatic ink jet printer, all nozzles of a printhead are spaced generally the same distance from a moving paper print substrate. Three voltage levels are selectively applied to each nozzle of the printhead. As the paper moves past the printhead, a bias voltage Vb is applied to all nozzles which have a static protruding meniscus which shape is determined by a balance between the internal pressure, surface tension, and bias voltage. When the paper arrives at a print row, nonprinting nozzles have a shadow voltage pulse Vs, the "shadow pulse," applied thereto, and printing nozzles have a higher magnitude print pulse Vp applied thereto. The magnitude of the shadow pulse Vs causes an additional excursion of the ink meniscus to form at each non-printing nozzle. The higher magnitude of print pulse Vp causes an ink filament to move from a printing nozzle to the paper. The time duration of each print pulse is varied in accordance with an ink density parameter up to a range that is determined by the duration of the shadow pulse.

Appl. No.:

8/622815

Inventors:

Ross Neal Mills - Boulder CO

Assignee:

imaging Technology international Corp. - Boulder CO

International Classification:

B41J 214

US Classification:

347 47

Abstract:

An ink jet printhead includes a nonconductive substrate into which a plurality of tapered nozzle holes are formed with the wide hole area coincident with an ink entry side and with the marrow hole area coincident with an ink exit side, and with an ink reservoir mounted on the ink entry side. A metal layer covers the interior of each nozzle hole, and also provides an electrical control-signal conductor on the ink entry side for each metallized nozzle hole. The metal layer also provides a tubular metal extension for each metallized nozzle, these extensions extending a common distance beyond the ink exit side. A plurality of metal conductors may be provided on the ink exit side to facilitate nozzle control using signal-multiplexing techniques, or a field compensation electrode may be provided on the ink exit side.

International Classification:

G01D 1516

US Classification:

346140R

Abstract:

An ink jet drop-on-demand print head comprises a plurality of tubular piezoelectric transducers each having two electrodes formed by an electrically conducting coating. A housing member holds the transducers in a position which includes at least one row of transducers. A substrate includes a plurality of electrical conductors, and the substrate is positioned so that each electrical conductor is adjacent one of the electrodes. A resilient connector means is provided which is not conductive along its length but is conductive across its width, and the connector means is positioned to make contact with a selected one of the electrical conductors and only one of the electrodes of one of the transducers. In a specific embodiment, the substrate comprises a flat conductor cable, and in a second embodiment the substrate comprises a printed circuit board.

International Classification:

G01D 1516

US Classification:

346140R

Abstract:

An ink jet drop-on-demand print head comprises a plurality of electromechanical transducers, and ink from a manifold is conveyed to the transducers. The fluid path between the transducers and the corresponding nozzle in the nozzle array comprises a resilient dual function means. The dual function means not only provides the fan-in section but also seals the fluid path in fluid tight relation without the use of any adhesive or bonding material.
