摘要： A method of making a printhead includes forming a channel member by providing a mold having a top portion having peaks and valleys and by tape casting a slurry of piezoelectric material into the mold and onto the peaks and valleys of the top portion of the mold to form a tape cast member having a bottom surface with peaks and valleys and a flat top surface and removing the tape cast member. After removing the tape cast member, the top surface of the tape cast member is embossed so as to provide peaks and valleys in opposite sides of the tape cast member wherein the valleys in the top surface are disposed in an offset relationship to the peaks in the bottom surface. Thereafter, the embossed tape cast member is poled to align the electrical dipoles within the piezoelectric material; and a coating of conductive material is formed over the top and bottom surfaces of the tape cast member and then cutting grooves through conductive coating into the top surface in the valleys of the tape cast member to form a channel member. Finally, an orifice plate is provided over top surface of the channel member and a substrate over the bottom surface of the channel member.

摘要： A method of fabricating a modulator for modulating an incident beam of light includes a substrate having a cavity formed therein and a plurality of spaced-apart deformable elements formed in the cavity. The deformable elements each has a base layer, a poled magnetic layer formed in the base layer and a first light reflection layer deposited on the magnetic layer for reflecting an incident beam of light. Between adjacent deformable elements on the base of the cavity is arranged a second light reflection layer. A conductive element formed in the substrate electro-magnetically energizes the deformable elements to deflect in the cavity. Incident light passing through each one of the first light reflection layers is caused to destructively interfere with light reflected from the second light reflection layers thereby causing modulation of the incident light.

摘要： A method of making a modulator for modulating an incident beam of light uses a substantially planar light reflection surface formed by a light reflection layer associated with a plurality of deformable elements and a light reflection layer associated with a plurality of fixed elements. The fixed and deformable elements are arranged in a cavity of a substrate supporting the modulator. Light is modulated when a current is applied to a conductive element operably associated with the deformable elements causing the light reflective layer associated with the deformable element to deflect towards the base of the cavity from its substantial planar relations with the light reflecting layer of the fixed element.

摘要： A dielectric member with an integral, electrically conductive surface is made by molding a substrate from a zirconia alloy powder using a tape casting process. The resulting green substrate is sintered and after sintering may be cut to the final desired size and shape. Once the insulating ceramic substrate has been formed, the surface of the substrate is modified using infrared laser energy. Through the impingement of infrared laser radiation upon the surface of the ceramic substrate, an electrically conductive region is produced on the surface of the substrate. In such manner, the entire surface can be made electrically conductive or a particular pattern can be traced. As an integral part of the substrate, the surface will not delaminate from the substrate. Further, because the modified surface region and the substrate are both a zirconia, the coefficients of thermal expansion of the substrate and the modified surface region will be closely matched.

摘要： A method for making electromechanical parts and tools having at least one micro-diameter electrically conductive thread incorporated therein is accomplished by molding the elements which form the base for the electromechanical part or tool from a ceramic material and, during the molding step, there are formed one or more bores through each of the base elements. The base elements may be formed individually or at a planar array for later separation into individual elements. The base elements are then supported on a micro-porous substrate within a vacuum chamber and one side of the base element is flooded with a molten electrically conductive material. By drawing a vacuum within the vacuum chamber beneath the micro-porous substrate, the molten electrically conductive material is caused to flow into and through at least one bore in each base element. The molten electrically conductive material is then cooled. In such manner, through the molding of the ceramic material into the desired shape with desired bores forming conduits for the molten electromechanical material, a variety of micro-electromechanical parts and tools can be fabricated.

摘要： Flexible and reusable lithographic printing tapes are prepared from a zirconia ceramic that is an alloy of ZrO.sub.2 and a second oxide chosen from MgO, CaO, Y.sub.2 O.sub.3, Sc.sub.2 O.sub.3, a rare earth oxide or a combination of any of these. These printing tapes have an average thickness of less than about 5 mm. In use, a surface of the zirconia alloy ceramic printing tape is imagewise exposed to electromagnetic radiation which transforms it from a lydrophilic to an oleophilic state or from an oleophilic to a hydrophilic state, thereby creating a lithographic printing surface which is hydrophilic in non-image areas and is oleophilic and thus capable of accepting printing ink in image areas. Such inked areas can then be used to transfer an image to a suitable substrate in lithographic printing. These printing tapes are directly laser-imageable as well as image erasable.
