摘要： Disclosed is a process for treating particles of selenium alloy to reduce fractionation when the particles are subsequently vacuum evaporated onto a substrate which comprises (1) heating particles of an alloy of selenium and an alloying component selected from the group are exposed to oxygen; (2) exposing the particles to water vapor; and (3) subjecting the particles previously exposed to oxygen and water vapor to a vacuum. Also disclosed is a process which comprises (1) providing particles of an alloy of selenium and an alloying component selected from the group consisting of tellurium, arsenic, and mixtures thereof; (2) forming selenium oxide on the surfaces of the particles; (3) converting the selenium oxide on the particle surfaces to selenious acid; and (4) removing the selenious acid from the particle surfaces.

摘要： Method and apparatus for applying a periodic negative voltage to a coronode for the prevention of a streaming phenomenon in electrographic devices. A negative polarity voltage signal is applied periodically to the bare wire coronode of a positive corona charging device. The negative polarity voltage signal is believed to prevent the formation of streamer sites associated with the pepper tracking copy quality defect. The negative polarity voltage signal is applied to the coronode in a manner having a minimal effect on charging functions.
