問題１
1.

A method of recovering metal components in slag generated duringoxidative refining of chromium-containing steel, comprising the steps
of:
reducing the slag from the oxidative refining of achromium-containing molten steel charge in a refining furnace, suchthat the total chromium concentration in the slag is adjusted between
0.3 and 3.0 wt%;
adding boron oxide to the slag which is then cooled;feeding the cooled slag into a blast furnace either directly orafter sintering the slag;
recovering the metal components from the slag into molten ironin the blast furnace by reduction;
pouring the molten iron out of the blast furnace;
performing oxidative refining on the melt by supplying oxygen;removing boron that has been recovered from the slag in the blast
furnace into the molten iron; andcharging the molten iron into the refining furnace and refining
the molten iron by decarburization.

2.

The method according to claim 1, wherein the specific consumptionof oxygen supplied is 2Nm3/ｔ for the molten iron.

問題２[0002]

Utilization of carbon-neutral biomass is one of the approaches
that need be taken to mitigate global warming. While various kinds ofbiomass exist, “wet” types such as sewage sludge, agricultural wastes,
livestock excreta, wastes from food plants and garbage are producedin larger quantities than dry types such as wood and, hence, they holda particularly great promise for effective utilization as resources
after recycling. However, wet types of biomass have such a high watercontent that they are not easy to recycle.

If fossil fuels were used

for drying and other purposes, recycled wet biomass would not be able
to contribute to mitigation of global warming.

A method and apparatus for converting sewage sludge to fuel isdescribed in JP 2005-319374 A. This technology is shown in FIG. 1;
sewage sludge is supplied to a drying furnace 11’, thence to acarbonizing furnace 12’ to generate carbide that can be used as fuel.
A heat source for drying and carbonization is provided by a sludge
incinerator 31 that burns part of the sludge. Part of the generated
carbide is supplied as fuel to the sludge incinerator 31 and thiscontributes to saving on the use of a fossil fuel in the sludge
incinerator 31.

Example 1
An electrode substrate 1, or a glass plate having an ITO anode2 formed thereon, was overlaid with thin films by vacuum evaporationin the following order: CuPc (a hole injection layer) 200 Å thick,acrylate-modified αNPD (a hole transport layer) 200 Å thick,acrylate-modified Alq3 (a light-emitting layer having an electron
injection and transport capability) 200 Å thick, and aluminum 150 Åthick as a cathode 4. After deposition of all layers of CuPc, αNPD and
Alq3, UV light (central wavelength, 365 nm; intensity, 100 mW) wasapplied for 10 seconds to crosslink the photo-reactive acrylate groups,thereby forming a polymerized organic layer 3.
[0036]A voltage (6 V) was applied between the anode (ITO) 2 and thecathode (Al) 4 to generate a current (6.5 mA/cm2), whereupon green light
was emitted at a luminance of 400 cd/m2. The device was evaluated forits durability at 85 °C; the half period of luminance was 2000 hr,indicating superior durability of the device at elevated temperature.
[0037]
Comparative Example 1
A device was fabricated as in Example 1, except that theacrylate-modified αNPD and Alq3 were replaced with αNPD and Alq3 freeof acrylate groups and that no UV irradiation was effected. The device
had a luminance of 400 cd/m2 and its half period was 700 hr, indicatingpoor durability of the device at elevated temperature.
