摘要： A plastic optical transmission element having a body in which the refractive index varies continuously in a radial direction from the interior toward the surface of the body, may be free from the troubles derived from irregularity of the index distribution and flare by having a layer containing a light-absorbing substance under the surface thereof. Such a layer may be formed by contacting an untreated element with a solvent containing the light absorbing substance, when the solvent is selected so as to be capable of at least partially dissolving the plastic of the element.

摘要： A distributed refractive index type optical transmission plastic article has a circular cross section of a radius r.sub.0 between 0.4 and 0.6 mm. A refractive index distribution of the optical transmission article substantially approximates predetermined ideal refractive index distribution curve at least in a range of 0.25r.sub.0 to 0.70r.sub.0 extending from a center axis toward a peripheral face of the article. The article has a refractive index n.sub.0 between 1.4 and 1.6 for its central part, a refractive index distribution constant between 0.3 and 0.7 mm.sup.-1, and a modulation transfer function (MTF) of at least 55%. This optical transmission article is made from uncured liquid substances each having a viscosity between 10.sup.3 and 10.sup.8 poises and refractive indexes n of n.sub.1 >n.sub.2 >n.sub.3 . . . n.sub.N when cured. N (N.gtoreq.3) of such uncured liquid substances are arranged in such a way that the refractive indexes n successively decrease from a central portion toward a peripheral portion, and concentrically laminated one upon the other to form an uncured strand fiber. The substances between adjacent layers of the fiber are mutually diffused, and at the same time or thereafter, the uncured strand fiber is cured, thereby completing the production of the optical transmission article.

摘要： 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.

摘要： A metal paste comprising ultrafine particles of a metal. The particles have a particle size of 1000 angstroms (0.1 micron) or less and are individually uniformly dispersed in an organic solvent. A process for producing a metal paste comprises the steps of evaporating a metal in a vacuum chamber in an atmosphere of an inert gas at a pressure of 10 Torr or less and of collecting the vapor of the evaporated metal on a cooling surface in the form of ultrafine particles having a particle size of 1000 angstroms (0.1 micron) or less, wherein a vapor of an organic solvent is introduced into the vacuum chamber while the metal is being evaporated. A method for preparing a metallic thin film having a thickness of between 0.01 micron and 1 micron uses a metal paste containing ultrafine metal particles having a diameter of 0.1 micron or less uniformly dispersed in an organic solvent. In the method, the metal paste is coated on a substrate, dried and sintered.
