    • A process for preparing a film consisting of at least about 90 weight percent of cubic cadmium sulfide is disclosed.In one step of this process, a cadmium sulfide target with a density of at least about 3.8 grams per cubic centimeter is provided. In a separate step, there is provided a heated substrate which is at a temperature of from about 50 to about 300 degrees Centigrade. The heated substrate is disposed at a distance of from about 2 to about 10 centimeters from the target.Both the heated substrate and the target are subjected to a pressure of from about 10.sup.-4 to about 10.sup.-9 Torr. Thereafter, the cadmium sulfide target is contacted with a laser beam with a wavelength of from about 100 nanometers to about 30 microns, an energy of at least about 1.0 watt, and a beam width of less than about 5 millimeters.
    • 公开了制备由至少约90重量%立方硫化镉组成的膜的方法。 在该方法的一个步骤中,提供密度为至少约3.8克/立方厘米的硫化镉靶。 在单独的步骤中,提供了处于约50至约300摄氏度的温度的加热衬底。 被加热的基底设置在离目标约2至约10厘米的距离处。 被加热的基底和靶都受到约10-4至约10-9托的压力。 此后,硫化镉靶与波长为约100纳米至约30微米的激光束,至少约1.0瓦特的能量和小于约5毫米的波束宽度接触。

    • A deashed coal-water slurry and process for preparing the same containing 65-85 percent of solids and 0.01-2.4 weight percent of dispersing agent. The slurry is comprised of a coal compact whose coal particles have a particle size distribution in substantial accordance with a specified formula. The coal-water slurry has a relatively low viscosity of less than 4,000 centipoise at a 75 percent solids content and, when it is pumped at either a constant or an increasing shear rate, its viscosity decreases. Also disclosed are a pumping process and an electrophoretic deashing cell and process.
    • 一种脱水的水煤浆和其制备方法,其含有65-85%的固体和0.01-2.4重量%的分散剂。 该浆料由煤粒子组成,其煤粒子具有基本上符合规定公式的粒度分布。 煤 - 水浆料在75%固体含量下具有小于4,000厘泊的相对较低的粘度,并且当其以恒定或增加的剪切速率泵送时,其粘度降低。 还公开了一种泵送过程和电泳去除电池和工艺。
