摘要： Selected scintillator materials provided in transparent block form for use in systems such as CT scanning systems employ a garnet host material for an activator ion which provides the desired luminescence. The garnet host material preferably includes gadolinium as one of its components in order to provide a transparent host material in bar form which has a high x-ray stopping power (where the radiation to be detected is x-ray radiation). Chromium, cerium and neodymium are preferred activator materials.

摘要： Polycrystalline ceramic bodies having uniform transparent optical characteristics are produced by providing a green compact, presintering that compact at a temperature in the range from about 1,350.degree. C. to about 1,650.degree. C. until the closed porosity stage is reached, hot isostatic pressing the presintered compact to collapse substantially all pores disposed at grain boundaries and resintering the hot isostatically pressed compact at a temperature in the range from 1,700.degree. C.-1,950.degree. C. to cause grain growth under conditions in which pores, within those grains which are consumed by the growth of other grains, collapse as the grain boundary of the growing grain passes through the location of the pore in the smaller grain being consumed.

摘要： Transparent, polycrystalline garnet bodies having desirable properties for use as laser material, luminescent x-ray scintillator materials and other uses are produced by mixing a chloride source solution of the desired cations with a basic ammonium solution to produce a precipitate having a substantially uniform composition which can be further processed to provide the desired transparent body. This precipitate is separated from the solution, dried, thermally decomposed at a temperature in the range from 700.degree. to 1,000.degree. C., pressed to form a compact, isostatically pressed at up to 60,000 psi to provide a green, unsintered compact having a density in the vicinity of 55% of theoretic density. That green compact is then sintered in oxygen at a temperature between 1,400.degree. and 1,700.degree. C. to produce the desired transparent body. Alternatively, the compact may be sintered in oxygen at temperatures in the range from about 1,400.degree. to about 1,600.degree. C. to a closed pore stage and then hot isostatically pressed at high pressure to provide the desired transparent body.

摘要： Cellular glass structures are made by foaming select silicone resins. A foaming agent is reacted together with the silicone resin to form a foam that carries the resin as a continuous separate phase distributed throughout the foam. The foaming agent is removed by decomposition, and the remaining silicone resin is crosslinked to retain the foamed structure. The silicone resin is then heated in a non-oxidizing atmosphere at a temperature that will pyrolize the resin. During pyrolysis, the resin densifies to foam a unique glass composition comprised of silicon, oxygen and carbon, where carbon is chemically bonded to silicon, but there are essentially no chemical bonds between carbon and oxygen.

摘要： Evaporated ceramic coatings are prepared by furnishing an ingot of a ceramic material, treating the ingot to reduce sources of gas within the ingot, and evaporating the ceramic material in the ingot by melting the surface of the ingot with an intense heat source. The evaporated ceramic is deposited upon a substrate as the ceramic coating. The reduced gas content of the ingot decreases the incidence of spitting and eruptions from the molten surface of the ingot, thereby improving the quality of the deposited coating, and facilitating increases in evaporation rates and coatings process production rates.

摘要： Wear resistant cutting tools are comprised of cutting tools implanted with at least one element selected from the group consisting of, chlorine, fluorine, bromine, iodine, sulfur, indium, gallium and tin. The elements are implanted within the cutting tools in at least an effective amount to increase the wear resistance of the insert, up to an amount that does not substantially impair the hot hardness and toughness of the tool.In a method for lubricating the interface between a cutting tool and a workpiece in a lathe turning operation, at least one element selected from the group consisting of fluorine, bromine, iodine, sulfur, indium, gallium and tin are implanted in the tool. The elements are implanted so that the elements can lubricate the interface between the cutting edge and workpiece during turning without substantially impairing the hot hardness and toughness of the cutting tool. A workpiece is then shaped with the tool by metal removal, within a range of cutting speeds that cause the implanted element or elements to lubricate the interface.

摘要： An improved LED lead frame packaging assembly includes a thermally conducting, electrically insulating material that enhances the thermal conduction and structural integrity of the assembly, a UV-resistant encapsulantmaterial, and an integral ESD material that reduces electrostatic discharge. The thermally conducting, electrically insulating material creates an electrically insulating, thermally conductive path in the lead frame assembly for dissipation of power and also acts as a mounting structure thus allowing for the use of a soft encapsulant material, preferably a silicone.
