  • Publication number: 20070013929
    Abstract: A new calibration scale is proposed for as a substitute for density values of a densitometer or equivalent neutral densities. A color reproduction range of a color reversal film is set on an xy chromaticity diagram. On the xy chromaticity diagram, there are established three straight lines passing through a chromaticity point corresponding to a standard white illuminant and principal wavelengths relative to primary colors R, G, B. Vertexes of a triangle containing the color reproduction range are determined on the three straight lines. Chromaticity values at the vertexes of said triangle are determined as primary colors R, G, B. Block dye density values c, m, y corresponding to the primary colors R, G, B are determined according to the equations R=10?c, G=10?m, B=10?y. The determined block dye density values c, m, y are used as a new calibration scale.

  • Patent number: 6504061
    Abstract: The present invention provides an alkoxylation solid catalyst with which an alkylene oxide adduct having a narrow adduct distribution can be produced while inhibiting formation of high molecular weight polyalkylene glycol having a molecular weight of about tens of thousands as a by-product. The alkoxylation catalyst comprises a metal oxide containing magnesium, aluminum, and at least one metal selected from the metals that belong to group VIA, group VIIA, and group VIII as a third component. The third component metal changes the structure of the active site in the catalyst, for example, by forming a metal oxide having a spinel-type structure with aluminum (e.g. when the third component metal is Mn, MnAl2O4 is formed), so that a side reaction of forming a high molecular weight polyalkylene glycol is inhibited.
