問１．銅精錬（クレーム翻訳）(出典：USP 4,830,667)

次のクレーム１～７を日本特許明細書の請求項１～７として翻訳しなさい。参考資料として上記出典の一部抜粋を添付しているが、これは翻訳対象ではない。
＜スタート＞
1. A process for removing sulfur from a molten copper mass containing sulfur in an amount up to
the sulfur content of Cu2S, up to about 5% nickel the remainder being essentially copper andassociated impurities comprising:(a) contacting said molten copper mass with a gas containing oxygen at a point or points above
about the midpoint of depth of said molten copper mass until said molten copper mass contains
sufficient oxygen to meet the sulfur specification of the product; while(b) sparging said molten copper mass with a gas from a point significantly below the midpoint of
depth of said molten copper mass; and(c) continuing sparging with an inert gas after contact between said molten copper mass and the gas
containing oxygen ceases.
2. A process as in claim 1 in which contact of said molten copper mass with a gas containing oxygen
is by top blowing.
3. A process as in claim 1 wherein said gas containing oxygen is air.
4. A process as in claim 1 wherein said sparging gas in step (b) is an inert gas.
5. A process as in claim 4 wherein said inert gas contains nitrogen.

6. A process as in claim 1 wherein sparging originates at or near the bottom of said molten coppermass.
7. A process as in claim 1 wherein during the latter part of sparging with inert gas the molten
copper mass is cooled whereby nickel is exsolved as nickel oxide from said molten copper mass.

＊参考部分
The present invention relates to the field of pyrometallurgical production of blister and/or refinedcopper from sulfide ores, concentrates, and/or secondary sources. More specifically, it relates to theefficient conversion of copper containing significant amounts of sulfur, e.g. up to about 20%, into
copper metal having a sulfur content less than about 0.1% or even less than 0.01% and a low
content of impurities amenable to oxidation.
EXAMPLE I
Three tonnes of copper assaying 3.1% nickel and 1.2% sulfur were melted using an oxy-fuel burnerin a ladle into the bottom of which had been installed a porous ceramic plug. The temperature of themelt was adjusted to 1300.degree. C. Nitrogen was blown through the plug at 40 liters/minuteduring meltdown and blowing. To effect conversion, air was blown at 10 m.sup.3 /minute through a
3.8 cm diameter schedule 40 pipe suspended 51 cm above the eye in the bath formed by the nitrogensparging. The fuel consumption rate was adjusted to offset heat losses and maintain a bathtemperature of about 1300.degree. C. After 30 minutes of blowing, the bath assayed (wt. %): 0.023 S,
1.24 Ni, 0.67 O. Blowing was resumed for one minute after which nitrogen stirring was continued
for 60 minutes while maintaining the temperature at about 1300.degree. C. At the end of this period,
the bath assayed (wt. %): 0.008 S, 1.13 Ni, 0.92 O. Then, the burner was turned off; the nitrogenrate was adjusted to 10 liters/minute, and the melt allowed to cool. After 45 minutes, the blister
temperature was 1215.degree. C., and it assayed (wt. %): 0.005 S, 0.55 Ni, 1.02 O.
Samples of mush taken at the end of cooling showed that this material contained little copper oxide
so that the ratio of copper as oxide to nickel as oxide was well below one. An oxygen efficiency close
to 100% was calculated based on the composition of the final bath.

次の米国特許明細書の一部抜粋を日本語に翻訳しなさい。

＜スタート＞As used herein and in the appended claims, the terms "calcine," "calcining," "calcination" andgrammatical variations thereof, refer to a process of heating a particulate substance below its
melting point to effect a chemical change in one or more component of the material, such as to drive
off carbon dioxide from a metal carbonate to form a metal oxide. Generally, calcining also leads to a
reduction in the number of material phases in a mixed-metal oxide composition. For example, a
powdered mixture of titanium oxide, barium carbonate and neodymium oxide initially contains
three distinct phases, one for each individual compound in the mixture. During calcination carbon
dioxide is driven off of metal carbonates such as barium carbonate to form oxides such as bariumoxide. In addition, initially separate metal oxide phases such as titanium dioxide, neodymium oxide,samarium oxide, and barium oxide, will typically merge together into one or more complex,mixed-metal oxide phase. The terms "calcinated powder" and "calcinated particulate material" as
used herein and in the appended claims refer to a powder or particulate material that has been
subjected to a calcination process.

問３．有機合成(出典：USP 7,259,263 、Appl. No.: 11/170,042)

次の米国特許明細書の一部抜粋を日本語に翻訳しなさい。
＜スタート＞
Commercially available N-tritylserine methyl ester (15.0 g, 41.5 mmol) in 350 mL toluene wasstirred with triethylamine (16 mL, 115 mmol) until the solids were dissolved. A solution of phosgene(20% w/w in toluene, 25 mL, 47.2 mmol) was then added and the solution was stirred for 2 h. The
mixture was then poured into 100 mL 1N HCl, and the layers separated. To the aqueous layer wasthen added 40 mL 3N NaOH, which was then extracted twice with 100 mL 1:1
toluene:dichloromethane. The combined organic layers were then washed once with 100 mL 1N HCl,twice with 100 mL 1N NaOH, and once with 100 mL brine. The solution was dried over sodium
sulfate then passed through a pad of silica gel (0.5'', 500 mL sintered glass funnel). The silica waswashed with 250 mL ethyl acetate and concentrated under vacuum to afford a crude foam (16.5 g,>100%).
