摘要： A method for micromolding ceramic articles and structures having spatial features as small as 0.1 .mu.m and having a depth ranging from 2.0 .mu.m to 100 .mu.m. A master mold of the article or structure to be molded is first fabricated using a silicon wafer and dry etching technology. A negative master mold is then produced by placing the silicon master mold device in a surrounding mold form and filling the surrounding mold form with a silicone or silicone rubber, preferably an RTV.TM. (a room temperature-vulcanizing silicone rubber compound). Such material replicates each of the micro features of the master mold in great detail to a resolution on the order of 0.1 .mu.m. The negative master mold is then used in a die to mold the desired individual elements or structures from a ceramic powder which is capable of replicating each of the micro features of the negative master mold to the desired resolution. Depending on the resolution required in a particular micromolded element, it may be necessary to use ceramic nano-particles in the micromolding process. For resolution of spatial features having dimensions as small as 0.1 .mu.m and a depth of about 2.0 .mu.m, ceramic nano-particles ranging in size from about 0.01 .mu.m to about 0.02 .mu.m can be used to micromold these features. If an integral structure is to be created from multiple micromolded ceramic elements, the elements are first assembled prior to sintering. Sintering results in an integration of the assembled elements to form a contiguous structure. A single element, or alternatively, multiple elements can be molded simultaneously from the stone mold cavity preferably using a dry pressing process or, in the alternative, a cold isostatic pressing process.

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： An imaging processor for receiving a medium for processing, the processor comprises a print head for providing and for directing a writing laser beam. A laser source also disposed in the image processor for creating a focusing laser beam for ultimately permitting adjustment of the writing laser beam. An imaging receptacle receives the medium and is exposed to both the writing and focusing laser beams, and the writing laser beam is periodically directed from the medium, to the imaging receptacle and back to the medium. A laser-absorbent coating is coated onto the imaging drum for absorbing the focusing laser beam that is received by the imaging receptacle for substantially eliminating transient oscillations in the writing laser beam.
