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.
