The disclosure is also directed to a metallization product of a ferrous oxide-rich molten slag.

    摘要： An integrated circuit including vertically oriented diode structures between conductors and methods of fabricating the same are provided. The diode is a metal-insulator diode having a first metal layer, a first insulating layer, a second insulating layer and a second metal layer. At least one asymmetric interface state is provided at the intersection of at least two of the layers to increase the ratio of the diode's on-current to its reverse bias leakage current. In various examples, the asymmetric interface state is formed by a positive or negative sheet charge that alters the barrier height and/or electric field at one or more portions of the diode. Two-terminal devices such as passive element memory cells can utilize the diode as a steering element in series with a state change element. The devices can be formed using pillar structures at the intersections of upper and lower conductors.

    摘要： In a dual-gradient drilling apparatus, a subsea solids processing unit includes a housing, a solids processing mechanism disposed in the housing between a drilling mud inlet and a drilling mud outlet, and a flushing mechanism configured to flush the solids processing mechanism with a flushing fluid. A subsea solids processing unit may be controlled by rotating the solids processing mechanism in a forward direction and increasing a drive torque when a measured speed of the solids processing mechanism is below a desired rotation speed. The desired rotation speed may be decreased when a measured torque exceeds a selected maximum and a rotation direction of the solids processing mechanism may be reversed when the measured speed falls below a selected minimum.

    摘要： A photoconductor with a charge transport layer having about 20-25% by weight of 4-N,N-bis(4-methylphenyl)-amino-benzaldehyde-N′,N′-diphenylhydrazone is in an essentially standard resin binder, such as a polycarbonate resin binder. Electrical characteristics are those of the larger amounts using conventional charge transport agents, and the larger amount of binder provides much improved wear resistance and consequently longer useful life of the photoconductor. Charge transport layers with only the foregoing bis-methyl material do exhibit moderate fatigue upon exposure to light. However, this can be overcome by adding 0.5% or less of a fluorenyl-azine as a light absorber, specifically 9-(p-diethylaminobenzylidenehydrazono)fluorene, in the charge transport layer. No antioxidant is required for electrical stability improvement.
