    Abstract: A drop emitting apparatus including a diaphragm layer (137) disposed on a fluid channel layer (131), a roughened bonding region (137A) formed on a surface of the diaphragm layer, a thin film circuit (138) having conformal raised contact regions (191) disposed on the bonding region, and a plurality of electromechanical transducers (139) adhesively attached to the raised contact regions and electrically connected to the conformal raised contact regions by asperity contacts formed between the conformal raised contact regions and the electromechanical transducers.

    Abstract: An apparatus and method is disclosed for bonding a nozzle plate to the front nozzle face of a printhead. A bonding station includes a heated printhead holder in opposed relationship to a nozzle plate holder with a curved lower surface. A nozzle plate having a row of nozzle holes and alignment apertures are formed by laser ablation in a thin polymer film. The film is moved into the bonding station, and the nozzle plate is aligned with pins on the curved nozzle plate holder surface. Both the printhead holder and nozzle plate holder are adjustable in directions perpendicular to the nozzle array on the printhead face and also rotationally. The adjustment insures that the nozzle plate, with adhesive applied to the bottom surface, makes initial tangential contact at the center of the nozzle array, resulting in accurate alignment of the nozzle plate holes with the nozzle array in the printhead face.

    Abstract: An optical element (50) for the selective deflection of a scan line in a process direction in a raster output scanner (ROS) electrophotographic printer (10). The optical element includes a chamber (54;Fig. 3) containing a nematic liquid crystal material having a variable index of refraction (n1(V)) as a function of voltage applied thereacross (Fig.2). The ROS includes a control and feedback system coupled to a variable voltage source (58) for applying a biasing voltage (V) across the optical element (50) to control the variable index of refraction (n1(V)) of the optical element for selectively deflecting the scan line in the process direction.

    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: Tintenstrahldruckköpfe, die eine erste Platte, eine zweite Platte und eine ausgehärtete Klebstoffzusammensetzung beinhalten, die zwischen der ersten Platte und der zweiten Platte eingebracht ist. Die ausgehärtete Klebstoffzusammensetzung hat eine Glasübergangstemperatur von mehr als etwa 115°C und bleibt stabil, wenn sie einem Acrylatmonomer ausgesetzt wird. Außerdem Tintenstrahldruckköpfe, die eine erste Platte, eine zweite Platte und einen ausgehärteten dünnen Klebstofffilm aufweisen, der zwischen der ersten Platte und der zweiten Platte angebracht ist und diese miteinander verklebt. Der ausgehärtete dünne Klebstofffilm enthält einen Polyimidfilm, der zwischen einer ausgehärteten ersten Klebstoffschicht und einer ausgehärteten zweiten Klebstoffschicht angeordnet ist. Verfahren zur Herstellung solcher Tintenstrahldruckköpfe.
