Abstract: A color conversion section for an imaging device carries out conversion to imaging data imaged by each medical imaging device for eliminating differences in color property of each imaging device, and generates standard color graphic data. To this standard color graphic data, a color conversion section for highlighting a specific tissue carries out color conversion for highlighting a designated specific biotissue, such as a blood vessel, to generate specific tissue highlighted graphic data. To this specific tissue highlighted graphic data, a color conversion section for a monitor carries out conversion for eliminating differences in color property of each monitor to generate display data. Color monitors display graphics based on this display data.

Abstract: The white chromaticity, in which the illumination environment is considered, is measured for each individual color monitor (100). A reference body (Q), comprising a perfect diffuser, is applied on the screen of the color monitor (100). By a test pattern display means (210), a test pattern (T) is displayed on the screen of the color monitor (100) based on tone values of the three primary colors R, G, and B that are stored in a tone value storage means (220). While fixing the tone value of the primary color R at 255, the tone values of the primary colors G and B are varied cyclically from 0 to 255 in a prescribed period by a tone value varying means (240). An operator inputs the result of comparing the color of the test pattern (T) and the color of the reference body (Q). When a comparison result indicating the matching of the two is input, a comparison result entering means (230) outputs an agreement signal.

Abstract: The tone reproduction characteristics of a color monitor are determined at high precision by visual recognition. A pattern display means (230) displays a test pattern, comprising circular patterns (50) and a background (60), on the screen of the monitor (100) to be measured. In the background (60), a reference pattern, which is generated by a reference pattern generating means (220), is formed of a black-and-white pattern, and has a prescribed reference luminance, is displayed, and in each circular pattern (50), an even pattern with RGB tone values designated by a tone value designating means (210) is displayed. The tone of the even pattern is varied so as to vary in brightness and color by a tone value varying means (240). When the circular patterns (50) become the same in brightness and color as the background (60), an operator provides a coincidence signal to a coincidence signal input means (250).

Abstract: The indication of correct color evaluation standards of a printed matter including a paper containing a fluorescent whitening agent, is enabled even in the case where the printed matter is observed under a light source that differs from the light source used for color measurement. A spectral reflectance Pt(&lgr;) of the paper under a light source T and a spectral reflectance Pu(&lgr;) of the paper under a light source U are measured in advance and a differential component, due to the fluorescent whitening agent, is determined as Fp(&lgr;)=Pu(&lgr;)−Pt(&lgr;). For a printed matter of dot percent S, a spectral reflectance Rt(&lgr;, S) under light source T is measured, and the measured values are subject to a correction process of adding an effective component within the differential component Fp(&lgr;) that is in accordance to dot percent S to determine an estimated spectral reflectance Rtu(&lgr;, S) under light source U.

Abstract: A transfusion preparation for intravenous infusion which contains glucose, electrolytes, a chelating agent, e.g., citric acid, a salt of polyhydric alcohol or monosaccharide phosphoric ester, e.g., sodium glycerophosphate and has a pH adjusted to 5 to 7.5. This preparation is free from coloring or precipitation on autoclave sterilization and can be administered into the central and peripheral veins without affecting venous tissue.

Abstract: A welding method for welding a base metal with a welding wire of specified alloy composition using a TIG welding process, automatically controlling an arc length between a nonconsumable electrode and the base metal, deflecting the arc forward in the welding advance direction by the influence of magnetic fields resulting from DC current flow through the welding wire to prevent arc blow, weaving the arc forward in the welding advance direction by pulsating the current flowing through the weld wire, and heat treating a final weld layer with the nonconsumable electrode.

Abstract: The invention is a process and apparatus for measurement of diffusible hydrogen within a metal, in which a metal sample is placed within an enclosed collector vessel for a predetermined time and at a predetermined temperature, and the total resultant effused gases within the collector vessel are fed to a gas chromatograph.
