Abstract: Systems and methods for managing electrical power at a worksite are described herein. A control system determines available sources of electrical power at the worksite. The control system establishes communications with one or more work machines at the worksite and commences monitor power usage of the one or more work machines. Upon receiving an indication that a work machine requires power, the control system determines the type of power to be used by the work machine. The types of power can include a grid power supply and a portable power supply. If the portable power supply is required, the control system transmits an instruction to move the portable power supply to the location where the electrical power is to be used.

Abstract: A thin ferritic steel sheet having an excellent shape fixability capable of being used for bending is provided, comprising: at least 0.027 to less than 0.05 mass % of C, 0.01 to 1.0 mass % of Si, 0.01 to 2.0 mass % of Mn, not more than 0.15 mass % of P, not more than 0.03 mass % of S, 0.01 to 0.1 mass % of Al, not more than 0.01 mass % of N, not more than 0.007 mass % of O, the balance being Fe and inevitable impurities, wherein a ratio of presence of {100} planes parallel with a face of the steel sheet to {111} planes is not less than 1.0, and TS×El, which represents a product of maximum tensile strength (TS) multiplied by rupture elongation (El) of the steel sheet, is at least 13,860 MPA %.

Abstract: An electrophotographic photoconductor is provided which includes a photoconductive layer formed overlying an electroconductive substrate, wherein the photoconductor includes in a top layer thereof a polysiloxane mixture selected from the group consisting of a polysiloxane mixture of an unmodified polysiloxane compound and a modified polysiloxane compound, a mixture of a methacryl modified polysiloxane compound and an alkyl modified polysiloxane compound, a mixture of a methacryl modified polysiloxane compound and a vinyl modified polysiloxane compound, and a mixture of an alkyl modified polysiloxane compound and a vinyl modified polysiloxane compound. The photoconductor has good durability.

Abstract: A heat-treatment-hardenable cold-rolled steel sheet having a high r value, comprising 0.010% or less of carbon, 0.05 to 0.5% of manganese, 1.0% or less of silicon, 0.001 to 0.030% of sulfur, 0.03% or less of phosphorus, 0.0050% or less of nitrogen, 0.005 to 0.10% of sol. aluminum, and 0.8 to 2.2% of copper with the balance being iron and unavoidable elements and, optionally incorporated therein, either or both of titanium and niobium and further nickel and optionally boron. The steel sheet can be manufactured by subjecting a cold-rolled steel sheet having this composition to recrystallization annealing at a temperature of 750.degree. C. or above and then heat-treating the steel sheet at a temperature ranging from 450.degree. to 700.degree. C. for 1 minute or longer. Alternatively, after the recrystallization annealing, the sheet can be cooled to a temperature of 450.degree. C. or below within 1 minute, followed by work deformation and heat-treating the work-deformed product at a temperature of 450.degree. C.

Abstract: A heat-treatment hardenable hot-rolled steel sheet having remarkably excellent cold workability comprising 0.0005 to 0.015% of carbon, 0.05 to 0.5% of manganese, 0.001 to 0.030% of sulfur, 1.0 to 2.2% of copper, 0.100% or less of phosphorus, 1.0% or less of silicon, 0.0050% or less of nitrogen, and 0.002 to 0.10% of sol. aluminum with the balance being iron and unavoidable elements and substantially comprising a ferritic single phase structure free from occurrence of pearlite. The steel may also contain 0.01 to 0.2% titanium, 0.005 to 0.2% niobium, 0.15 to 0.45% nickel and/or 0.0001 to 0.0030% boron. The steel sheet is produced by hot-rolling the steel at a temperature above the Ar.sub.3 point and coiling the hot-rolled steel strip at a temperature of, preferably, 350.degree. C. or below. The resultant steel sheet is relatively easy to work, and its strength can be dramatically increased by heat treatment for a short period of time after working.
