  • Patent number: 7628840
    Abstract: Each of the metal nano-particles present in a dispersion, which comprises at least one metal selected from the group consisting of precious metals and transition metals or an alloy of at least two metals selected from the foregoing metals, comprises a metal particle in which an organic metal compound of a fatty acid and/or an amine-metal complex is adhered to the periphery of the metal particle. This organic metal compound and the amine-metal complex are admixed together in a solvent and then the resulting mixture is subjected to a reducing treatment to thus form a dispersion containing metal nano-particles in a concentration of not less than 5% by mass and not more than 90% by mass. The resulting dispersion is applied onto the surface of a base material, followed by drying the applied layer of the dispersion and then firing the dried layer of the dispersion at a low temperature to thus form a thin metallic wire or a metal film having conductivity.

  • Patent number: 4779987
    Abstract: An improved method of spectrographically measuring density of a strip of photographic negative color film is disclosed. The method includes the steps of concurrently projecting an image of a photographic negative color film, having certain images recorded thereon, on each of a plurality of smaller divisional light beam receiving faces of an image receiving element with the aid of a plurality of projection optical systems. The optical systems include a color separating filter for separating projected light into three primary colors. The method further includes electrically scanning a number of photoelectric converting elements located on each light beam receiving faces, producing an output signal obtained by electrical scanning each face and storing the signal, and measuring relative density, degree of saturation and average density with respect to a part on the photographic negative color film corresponding to each of the light beam receiving face with reference to the stored signals.
