    摘要： A plurality of ink jet printheads are produced from two aligned and bonded substrates by an improved fabrication method. The confronting surface of one of the substrates contains a plurality of linear arrays of heating elements and driver circuitry, and the confronting surface of the other substrate contains a plurality of sets of shallow channel recesses, reservoir recesses, and alignment openings. Prior to mating of the substrates, the substrate surface having the channel recesses is coated with a layer of thermosetting adhesive, and a thick film layer is deposited on the substrate surface having the heating elements and driver circuitry and patterned to provide a plurality of vias therein at predetermined locations. The vias expose the heating elements, provide ink bypass trenches, and provide a number of groupings of small pits. In one embodiment, the alignment openings are used to visually align and mate the substrates, so that each alignment opening is aligned with a respective one of the groups of small pits in the thick film layer. To prevent misalignment between the substrates before the adhesive layer is cured, a UV curable adhesive is inserted into the alignment openings and into each group of small pits in the thick film layer aligned therewith and cured, thus fastening the substrates together. The fastened substrates are placed in a curing oven without lost of alignment therebetween and the thermosetting adhesive is cured. The bonded substrates are then diced into a plurality of individual printheads.

    摘要： A light shutter is provided wherein a first plate which includes a pixel electrode for use in applying a includes a background electrode located adjacent the pixel voltage potential across a ferroelectric material also electrode and substantially surrounding the pixel electrode, whereby an electronic mask can be created adjacent the pixel electrode in the ferroelectric material. A second plate which, along with the first plate sandwiches the ferroelectric material, includes a backplane electrode which is used in conjunction with the pixel and background electrodes on the first plate for applying voltage potentials across the ferroelectric material. By maintaining a minimal amount of spacing between the background electrode and the pixel electrode, a voltage potential can be applied between the background and backplane electrodes so that the ferroelectric material located adjacent the pixel electrode can be maintained in, for example, a non-light transmissive state whereby the contrast between the pixel and inter-pixel regions is greatly improved. Image bars or displays can be formed by arranging a plurality of light shutters (and consequently, pixel electrodes) on the first plate with one or more background electrodes surrounding the plurality of pixel electrodes. Additionally, the background electrode and/or other electrodes can be used for applying electric fields to the ferroelectric material which are non-parallel to the polarization direction of the molecules of the ferroelectic material to reduce the time required to change the ferroelectric material between light transmissive and light blocking states.

    摘要： A method and apparatus for applying a coating to a front face of an ink jet print head die or print head die comprise positioning a die in a cut out in a top surface of a block such that the die extends from the top surface of the block. An applicator such as a roller or flat blade is used to apply the coating to at least an upper surface of the die as the applicator rides along the upper surface of the die. When a roller is used as the applicator, the roller has a recess corresponding to the extension of the die from the top surface of the block. The roller recess contains a piece of elastomeric material which extends to an outer portion of the roller adjacent to said roller recess. The method and apparatus facilitate transfer of a thin, uniform film of coating to an ink jet printer print head die or a completed ink jet printer print head.
