    摘要: An orange broad-band emitting phosphor is a titanium-activated lanthanum oxysulfide containing up to about 0.05 moles of titanium per mole of lanthanum oxysulfide host. The phosphor is prepared by incorporating titanium oxide in the desired ratio to lanthanum into the mixture at the time the lanthanum is sulfurized in the presence of an alkali metal carbonate, to form lanthanum oxysulfide.

    摘要: A process suitable for reclaiming europium-activated yttrium oxysulfide contaminated with europium-activated yttrium oxide and other non-rare earth cathodoluminescent phosphors comprises forming a relatively uniform admixture of specific fluxing agents, the contaminated yttrium oxysulfide phosphor, a sufficient amount of reactive rare earth source selected from reactive yttrium and europium sources to achieve a predetermined yttrium to europium ratio in the admixture and an excess of the theoretical amount of sulfur required to convert the yttrium oxide and the yttrium source to yttrium oxysulfide, heating the admixture at a temperature of at least 850.degree.C in non-oxidizing atmosphere for a time sufficient to convert the yttrium oxide and the yttrium source to a europium-activated yttrium oxysulfide whereby the rare earth materials form a cathodoluminescent material and whereby the non-rare earth materials form water soluble reaction products, washing the resulting material with sufficient water to remove water soluble materials leaving a cathodoluminescent europium-activated yttrium oxysulfide phosphor.

    摘要: An electrophotographic copy machine includes a system manager which controls the operation of the copy machine based on a plurality of performance levels corresponding to fuser copy quality characteristics, i.e., TPE, gloss and fuse fix. Each performance level corresponds to job parameters of a job to be performed, such as black and white paper copies, black and white copies on 11".times.17" or A3 size paper, black and white transparency copies, and color copies. When a particular job is requested, if the temperature of the fuser roll or pressure roll is below a minimum temperature required by the corresponding performance level, the system manager either prevents operation or reduces the copy rate until the minimum temperature requirements are met. The result is consistent fuser performance of high quality copy output.

    摘要: An improved (Gd.sub.1-x Tb.sub.x).sub.2 O.sub.2 S X-ray phosphor, wherein x is from 0.0003 to 0.0045, and persistence causing impurity ions are kept below 5 ppm, exhibits increased brightness in the blue region of the spectrum, while exhibiting acceptably low persistence for X-ray intensifying screen applications.
