    摘要： The present invention provides a deoxidizing agent for boilers excellent in an oxygen removal effect under wide temperature conditions. The deoxidizing agent for boilers comprises (A) a hydroxylamine compound represented by the following general formula (I), (B) a heterocyclic compound having an N-substituted amino group, and (C) an aminophenol derivative represented by the following general formula (II),

    wherein R 1 and R 2 each independently represent an alkyl group having 1 to 5 carbon atoms;

    wherein R 3 to R 6 each independently represent any one of (a) the following general formula (III), (b) -OR 10 and (c) -R 11 , at least one of R 3 to R 6 representing (a), and R 10 and R 11 each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms;

    wherein R 7 represents a single bond or an alkylene group having 1 to 4 carbon atoms, and R 8 and R 9 each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.

    摘要： A method for measuring concentration of a dissolved substance is provided, which can judge whether or not a quantity of a reagent added to a sample is proper when the concentration of a dissolved substance in the sample is measured. A reagent including a coloring agent is made by adding a coloring agent to the reagent, and the coloring agent allows a measured solution to develop a color transmitting a region component light for a dissolved-substance concentration measurement selected from any of three region component lights of red, green, and blue obtained by transmitting a light including a visible light region to the measured solution colored by addition of the reagent to the sample, and dividing a light of the visible light region of a transmitted light thereof into roughly three portions. Next, based on the transmitted light from the measured solution to which the reagent including a coloring agent is added, an absorbance of the region component light for the dissolved-substance concentration measurement, and an absorbance A3 of another region component light resulted only from the coloring agent are calculated. Whether or not the reagent in a necessary quantity is added to the sample can be judged by comparing the absorbance A3 and a standard absorbance A0.

    摘要： [PROBLEM] In space-conservative fashion, at low cost, and with high efficiency, to carry out absorption of gas produced at the interior of a battery. [SOLUTION MEANS] Secondary battery 21 is provided with case 3 in which positive electrode 10 and negative electrode 11 are sealed together with electrolyte, and with explosion prevention valve 4 for allowing escape of high-pressure gas present at the interior of case 3 when pressure within case 3 rises; and is further provided with gas absorber 13 or 14 for absorbing high-pressure gas. Gas absorber 13, includes gas-absorbent material 6 and capsule 5, which comprises hot-melt material, and is provided within case 3, this capsule 5 including, at the interior thereof, gas-absorbent material 6. Furthermore, gas absorber 14, which may be provided outside case 3, may include gas-absorbent material 6; cartridge case 14a which houses, at the interior thereof, gas-absorbent material 6; gas inlet valve 14b for causing high-pressure gas to flow thereinto; and gas outlet valve 14c for causing high-pressure gas to flow out therefrom.
