Stephen Temple,Robert Alan Harvey,Mark Richard Shepherd,Paul Raymond Drury,Angus Condie,Salhadin Omer +5 more
TL;DR: In this article, a method of manufacturing an ink jet print head includes the steps of bonding a body of piezoelectric material to a base plate, and cutting channels into the PZT material to form ink chambers which are actuated by applying voltages to electrodes provided on surfaces of the chambers.
Patent
Fluid Supply Method and Apparatus
TL;DR: In this article, a method and apparatus for supplying fluid to a deposition device or printhead using the through flow principle is presented, where the pressure of fluid entering and exiting a printhead is controlled directly at the printhead by respective pressure controllers, preferably a transducer and control system or a weir.
Patent
Method of printing
TL;DR: In offset printing as discussed by the authors, a layer of varnish or similar coating material is deposited onto a print drum and an ink image pattern layer is printed upon this layer using a technique such as inkjet printing.
Patent
Fluid pumping and droplet deposition apparatus
TL;DR: In this paper, the authors present a planar construction of a rigid and flexible chamber wall for drop-on-demand ink jet printing with an electromagnetic actuator operating under the principle of flux modulation.
Patent
Nozzle plate for droplet deposition apparatus
TL;DR: In this paper, a polymeric material of the insert located within an aperture (28) formed in a body of the nozzle plate is used to fill the aperture of the inlet.
