    摘要: Methods and apparatus for protecting extruded metal powder green bodies (34) during firing are provided. In certain embodiments, one or more green bodies (34) are housed in a non-gas tight chamber (13) located in the hot zone (24) of a cold-wall vacuum/atmosphere furnace (10). Furnace gas, e.g., hydrogen, is supplied to the interior of the chamber (13). The resulting one-way flow out of the chamber (13) protects the green bodies (34) from the backflow of burn-out products, as well as from contaminants arising from the walls and internal components of the furnace (10). In other embodiments, green bodies (34) are housed in individual non-gas tight containers (36). The containers (36) minimize the amount of furnace gas which comes into contact with the green bodies (34) during sintering and thus minimize the level of exposure of the green bodies (34) to oxidative impurities in the furnace gas. When composed of the same material as the green bodies, the containers (36) also perform a getter function.

    摘要: The present invention relates to photoconductive elements having an electrically conductive support, an electrical barrier layer and, disposed over the barrier layer, a charge generation layer capable of generating positive charge carriers when exposed to actinic radiation. The electrical barrier layer, which restrains injection of positive charge carriers from the conductive support, comprises a crosslinker, a crosslinkable condensation polymer having as a repeating unit a planar, electron-deficient, tetracarbonylbisimide group.
