摘要： A method of making a microceramic electromagnetic light shutter, includes forming a micromolded bottom ceramic portion in the green state with a sacrificial fiber having a first and second end portion and being shaped in the form of a coil, mounted on its surface; forming a micromolded top ceramic portion in the green state having surface features that include a pair of bearing structures, at least one stop structure, and a first and second through-hole; assembling the top and bottom micromolded ceramic portions with the first and second ends of the sacrificial fiber being drawn through the first and second through-holes, respectively, and sintering such assembled structure to form a unitary ceramic body; etching through the first and second through-holes to etch away the sacrificial fiber to thereby provide an embedded coil receiving cavity. The method further includes filling the coil receiving cavity with a conductive material to form an embedded coil; providing a light aperture through the unitary ceramic body and a first and second recess in the unitary ceramic body; mounting a ferromagnetic element in the first recess; and mounting a shutter drive mechanism, having a shutter blade in the second recess and in operative relationship to the embedded coil and the ferromagnetic element, and such shutter blade being movable between light blocking and light passing positions relative to the light aperture so that when a drive voltage is applied to the coil, a field is created which provides a driving force to the shutter drive mechanism to move the shutter blade to the light passing position and when the voltage is discontinued the ferromagnetic element provides a torque on the shutter drive mechanism to return it to the light blocking position.

摘要： A method for forming an embedded multiwound microcoil in a ceramic substrate including the steps of forming a sacrificial mutiwound microcoil to be used in the ceramic substrate by wrapping a first sacrificial coil winding about the midsection of a sintered ceramic bar thereby forming a one winding sacrificial coil structure; dipping the one winding sacrificial coil structure in a sol-gel precursor and then forming an encapsulated one winding sacrificial coil structure from such sol-gel precursor; wrapping a second sacrificial coil winding about the midsection of the encapsulated one winding sacrificial coil structure thereby forming a two winding sacrificial coil structure. The method further includes incorporating the multiwound sacrificial coil structure into a green ceramic substrate; sintering the green ceramic substrate at a sufficient temperature to burn away the sacrificial coil windings thereby forming an embedded coil receiving cavity; flowing molten electrically conductive material into the embedded coil receiving cavity; and cooling the molten electrically conductive material to form the multiwound microcoil embedded in a ceramic substrate.

摘要： A method of engraving pre-sintered ceramic articles involves providing a source of laser energy for forming a polyester mask having a predetermined spiral pattern etched therein. To form the polyester mask, means are provided for computationally communicating a predetermined engraving pattern to the source of laser energy. Once the polyester mask is formed, it is overlaid onto the ceramic article forming a laminate and the laminate is bombarded with a hard alumina grit to form the spiral pattern in the ceramic article. After the ceramic article is engraved with the predetermined spiral pattern, the polyester mask is removed exposing an engraved ceramic article.

摘要： A method of cutting, slicing or perforating photographic imaging elements using certain cutting tools is disclosed. The cutting tool material includes zirconia and yttria at a molar ratio of yttria to zirconia from about 0.5:99.5 to about 5:95. The cutting tool is essentially a tetragonal crystal phase grain for the interior in a surface of cubic crystal phase grain or monoclinic crystal phase grain. This provides a hard, tough outer surface with a tough core. The cutting tool material can also be a composite of zirconia-alumina with or without surface modification.

摘要： An improved gear micropump (10) for delivering corrosive materials, particularly photographic materials, such as dyes and emulsions, has a pair of intermeshing gears (16,18) rotatably mounted on zirconia ceramic shafts (24,26). The ceramic shafts of the invention may be formed from zirconia and zirconia composite materials. The gear micropump (10) having the zirconia ceramic shafts (24,26) eliminates pulsation during fluid delivery and is resistant to wear and abrasion. Moreover the zirconia ceramic shafts (24,26) are strongly resistant to chemicals like photographic emulsions and dyes and, therefore, do not contaminate product with corrosive materials.
