[Object] The present invention relates to a turmeric pigment composition. More specifically, the present invention provides a turmeric pigment composition in which aggregation and sedimentation of a turmeric pigment over time is effectively prevented even when a concentrated amount of turmeric pigment is incorporated in a solvent; the turmeric pigment composition also ensures a desirable color-developing property, and is capable of stably adding a deep color with a bright tone, which was never accomplished by a hitherto-known colorant.

A method for measuring bromate ions includes: an adding step of adding a fluorescent substance whose fluorescence intensity changes by the coexistence of bromate ions to sample water; a measuring step of measuring the fluorescence intensity of the fluorescent substance; a difference calculating step of calculating a difference between the fluorescence intensity measured and a reference fluorescence intensity of reference sample water that contains no bromate ion; and a concentration calculating step of calculating bromate ion concentration from the calculated fluorescence intensity difference. The measuring step includes a step of measuring the fluorescence intensity at any one of a case where an excitation wavelength is 264 nm and an emission wavelength is 400 nm, a case where the excitation wavelength is 264 nm and the emission wavelength is 480 nm, and a case where the excitation wavelength is 300 nm and the emission wavelength is 400 nm.

Method and apparatus for measuring bromate ions

A method for measuring bromate ion is provided that provides high-sensitivity measurement results more simply and more quickly than conventional bromate ion measurement methods. A fluorescent substance that is quenched by coexistence with bromate ions is added to a sample 130 and the fluorescence intensity of the fluorescent substance after quenching is measured, the measured fluorescence intensity being subtracted from the fluorescence intensity of a standard sample containing no bromate ions to calculated the fluorescence intensity difference. The bromate ion concentration is calculated from the calculated fluorescence intensity difference, using a pre-determined calibration line between the fluorescence intensity difference and the bromate ion concentration.

Provided are a method and an apparatus that enable rapid and automatic determination of the coagulant injection rate in a process of water treatment through coagulation and sedimentation. Using a coagulation analyzer comprising sample tanksA toD each for keeping a predetermined amount of raw water, a water supply pump, water supply/discharge valvesfor raw water and washing water, mixersA toD, a coagulant injection unit, and a detectorfor determining the particle size and the particle number of flocs, the time within which the coagulantinjected into the sample tanks is dispersed by mixing and the particles begin to agglomerate (agglomeration start time) is determined, and based on the thus-determined agglomeration start time, the coagulant injection rate is determined, or the amount of the coagulant to be injected is controlled.

While relatively transporting a wire to be inspected and a unit including a first light source for emitting a first beam, a second light source for emitting a second beam which intersects with said first beam at a predetermined reference position, and a photodetector for detecting reflection light of said first and second beams derived from said first and second light sources respectively, a relative position between said unit and said wire is detected as a first position when said first beam is reflected from said wire. Then, while relatively moving said unit and said wire, another relative position between said unit and said wire is detected as a second position when said second beam is reflected from said wire. Then, a height of said wire from said reference position is calculated based on an interval between said first and second positions.

A method of alignment between a mask and a semiconductor wafer is disclosed. At least one linear Fresnel zone plate lens is provided on the mask, and first and second reflecting gratings are provided one the semiconductor wafer. The first reflecting grating includes a plurality of concaves or convexs arranged with a constant pitch P.sub.1, and the second reflecting grating includes a plurality of concaves of convexs arranged with a constant pitch P.sub.2 different from the pitch P.sub.1 in the first reflecting grating. A monochromatic radiation is irradiated on the mask and first and second reflected radiations from the first and second reflecting gratings are detected by first and second detectors, respectively. A difference value between the outputs of the first and second detectors is obtained, and the relative position between the mask and the semiconductor wafer is displaced in accordance with the difference value.
