A silver halide photographic material is disclosed, comprising a support having thereon at least one photographic silver halide emulsion layer containing silver halide grains dispersed in a dispersing medium, wherein in said silver halide grains, a total weight of the portion where at least one polyvalent metal ion is doped in an amount of not less than 1.times.10.sup.-4 mol per mol of the doped silver halide, is at least 10% based on the total weight of said silver halide grains.
摘要:
Negative type silver halide photographic emulsions are provided, formed by growing silver halide grains in the presence of a water-soluble iridium salt in a molar ratio of 3.times.10.sup.-4 mol or more to the amount of the total silver halides used in the formation of the silver halide grains and then chemically sensitizing the surfaces of the grains formed with a sulfur compound or with a sulfur compound and a gold compound. The present emulsions have high sensitivity and extremely improved variation of sensitivity and gradation under broad exposure conditions of high intensity exposure and low intensity exposure.

摘要:
A turbine generator system includes a turbine power generation unit including a generator and a turbine for driving the generator. The turbine generator system also includes an evaporator, a condenser, a medium feeding pump, a circulating pump, and a feeding passage. The evaporator receives heat from a heat source and supplies a working medium in a vapor phase containing a lubricant to the turbine power generation unit. The condenser condenses the working medium which has flowed through the turbine. The medium feeding pump raises a pressure of the condensed working medium and feeds the working medium to the evaporator, and the working medium extracted from the evaporator is supplied through the feeding passage to bearings in the turbine power generation unit.
