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.

摘要： A method of making a print head (100) includes forming a body (110) having a closed base (120) and independent fluid containment compartments (220) formed about the closed base (120). A substantially planar piezoelectric transducer (80) comprising a slab (60) of piezoelectric material provides a means of enclosing each of the independent fluid containment compartments (220). Each of the independent compartments has operably associated therewith one of a plurality of first electrodes (20) arranged on a first surface (62) of the slab (60) of piezoelectric material and a portion of a second electrode (22) arranged on an opposite second surface (64). By applying a voltage to the first and second surface electrodes (20, 22) in a predetermined manner induces an electric field in a portion of the slab (60) of piezoelectric material and thereby forces fluid composition through the independent fluid containment compartment (220).
