  • Patent number: 6841188
    Abstract: A method of developing latent fingerprints involves the preparation of an 8-quinolinol complex by mixing a solution of 8-hydroxyquinoline or a derivative with a complexing reagent such as a metal salt. The solution is then applied to a porous substrate, such as paper, containing the latent fingerprint where the soluble complex is adsorbed onto the surface of the latent print and precipitates thereon. The unadsorbed solution is then removed from the substrate allowing the precipitate to highlight the latent image. The choice of the complexing reagent will determine the color of the precipitate and whether or not it is flourescent.

  • Patent number: 6805903
    Abstract: A method for forming an optical thin film used for optical elements of laser systems including high-energy lasers and an optical element of optical apparatuses is provided. The optical thin film can be easily formed on a desired substrate with reproducibility by vapor-depositing a porous fluoride layer for preventing reflection in the deep ultraviolet region, and can be easily removed in a short time to reuse the substrate if the thin film damaged. A water-insoluble material (2) for preventing reflection is vapor-deposited onto an optical element substrate (1). A water-soluble material (3) having a higher particle energy is vapor-deposited onto the surface of the water-insoluble material (2). The water-soluble material (3) permeates deep into the water-insoluble material (2) to form a mixed film on the surface of the substrate (1). Then, the water-soluble material (3) is dissolved and removed to form a porous thin film (5) comprising the water-insoluble material (2).

  • Patent number: 6780469
    Abstract: The present invention relates to an artificial leather having nap very little oriented on the surface and having short fibers densely, and hence having a good nubuck-like look and hand, and also relates to a production process thereof. The present invention provides an artificial leather having a nap surface of ultra-fine fibers at least on one side, which is formed by applying an elastic polymer to an ultra-fine fiber-entangled substrate, characterized by being 0.3 g/cm3 or more in the apparent density of the artificial leather, being 0.5 mm or less in the nap length, and being 25% or less in the R value obtained from the goniometric reflectance distribution measured with the nap surface rotated from 0 degree to 180 degrees using a goniophotometer.

In an exemplary embodiment, a microbump textured substrate is produced having colloidal particles on a surface thereof at a density of at least about 25 particles per 25 &mgr;m2, wherein the surface topography includes a Rp value of about 20-200 Å, a micro-roughness Rq of about 10 Å or less, and a ratio of Rmax:Rp of about 1.4 or less. An exemplary method includes first providing a substrate surface having a surface micro-roughness Rq of about 10 Å or less and depositing colloidal particles on the surface to provide a Rp value of about 20-200 Å and a ratio of Rmax:Rp of about 1.4 or less. In a further exemplary embodiment, the method increases the micro-roughness Rq, but to a value that is still less than about 10 Å with Rmax:Rp still of about 1.
