Abstract: In accordance with the invention, there are jet stacks, ink jet print heads, and methods of making jet stacks and ink jet print heads. The method of making an ink jet print head can include providing a partial jet stack including a diaphragm (104), a plurality of port holes (106), and having an ink outlet side (109) and providing a polymer planarized piezoelectric array (115). The method can also include bonding the polymer planarized piezoelectric array to a side opposite to the ink outlet side of the partial jet stack using an adhesive, wherein the partial jet stack is aligned such that the planarized polymer (117) covers the plurality of port holes, and using the partial jet stack as a mask to extend the port holes through the polymer by ablating the polymer and an excess portion of the adhesive from the ink outlet side using a laser beam, generated by a laser.

Abstract: An inkjet external ink manifold is provided that allows for use of a jet stack that does not internally contain ink manifolds. The external ink manifold has a manifold body that includes one or more ink manifold chambers and includes ports arranged to connect the chambers to one or more ink reservoirs. The external ink manifold further includes an adhesive layer overlying and sealing the ink manifold chambers The adhesive layer includes a plurality of ports arranged to connect the external ink manifold chambers to the jet stack.

Abstract: The structure has an adhesive standoff layer attached to a liner layer. Standoff apertures (63) are formed in the liner layer and the adhesive standoff layer. A mask adhesive layer is attached to the liner layer. A mask liner layer (75) is attached to the mask adhesive layer. Mask apertures are formed in the mask adhesive layer and the mask liner layer in alignment with the standoff apertures. Independent claims are also included for the following: (a) a method of making a standoff/mask structure (b) a method of making an interconnected electrical circuit structure.

Abstract: A layered photosensitive imaging member is modified to reduce the effects of interference within the member caused by reflections from coherent light incident on a base ground plane. The modification described is to form the ground plane surface by an electroforming process which leaves the surface with a black finish. Light incident on the ground plane is absorbed, eliminating the reflections which contribute to the interference effect at the imaging member surface.

Abstract: An optical element for laser beam deflection in a raster output scanner (ROS) of an electrophotographic printer. The optical element (50) includes a chamber (54) containing a ferroelectric liquid crystal material having a variable index of refraction as a function of voltage applied thereacross. The ROS includes a control system coupled to a voltage source (58) for applying a voltage across the electrodes (53,57) of the optical element to control the variable index thereof in conjunction with the rotation of the polygon. This enables the beam to be positioned on a selected portion of each facet of the polygon as the polygon rotates, as well as compensating for facet alignment errors and/or belt motion errors.

Abstract: A holographic display includes "segmented" images (24) configured as if positioned in separate viewing "cells" (28, 28a corresponding spatially to preselected subareas of a desired display area with invisible segmenting cell sides. Constantly viewable unsegmented holographic images recorded in the same recording medium (16 min ) as the segmented images or on a separate recording medium can be multiplexed into the display area using a conjugate light source (50) of a different frequency or having a different polarization condition (e . g., unpolarized) from the conjugate light source (20) used to project the segmented images to be selectively displayed/blocked.

Abstract: The present invention is a multiple spot laser assembly, comprising a plurality of laser diodes, and a plurality of mounts, which include a support surface, upon which the laser diode are permanently affixed. The mounts, including the base plate and/or heat sink, further include a mating feature along an edge thereof for aligning a first mount with an adjacent mount, the two mounts abutting along at least one common edge. The mating features assure the accurate alignment of the laser diodes on the adjacent mounts when the mounts are assembled into a multispot laser light source.
