  • Patent number: 9475307
    Abstract: The present invention relates to a method of marking a substrate that comprises a color forming material, comprising the steps of: activating a region of the substrate so as to transform it from an inactive, low reactive state to an active, high reactive state; irradiating a part of the activated region with an initial color changing radiation to effect an initial color change to a first color; and irradiating a part of the substrate that has been changed to the first color with a high power density beam of visible electromagnetic radiation to effect a further color change of the irradiated region to a second color.

  • Patent number: 6649257
    Abstract: A visually decorative material having bulk decorative effects which may be used as a surface covering or for creating decorative objects, and the method of manufacturing same. The material is formed of a pigmented castable liquid vehicle having dispersed therein a quantity of discrete particles of higher specific gravity than the liquid vehicle. The material is formed by pouring the vehicle-particle composite onto a suitable backing. As the liquid flows onto the backing, the particles sink and disturb the uniformity of the pigment distribution. This causes the desired bulk decorative effects in the form of “comet-tails” and other dimensionally extended streaks and curves. Thereafter, a second casting is applied using a formulation which is at an earlier stage of curing. The backing may be removed after the castable liquids solidify or may be left in place to create a laminate. As a floor-covering, the material may be poured in place onto a suitable sub-flooring.

In manufacturing such an optical recording medium, the surface layer is disposed in a manner to oppose stamper where reversed uneven pattern is formed and the intermediate layer including rigidity rendering material is stacked on the surface layer.

  • Patent number: 6524381
    Abstract: Methods and apparatus are provided for uniformly depositing a coating material from a vaporization source onto a powdered substrate material to form a thin coalescence film of the coating material that smoothly replicates the surface microstructure of the substrate material. The coating material is uniformly deposited on the substrate material to form optical interference pigment particles. The thin film enhances the hiding power and color gamut of the substrate material. Physical vapor deposition processes are used for depositing the film on the substrate material. The apparatus and systems employed in forming the coated particles utilize vibrating bed coaters, vibrating conveyor coaters, or coating towers. These allow the powdered substrate material to be uniformly exposed to the coating material vapor during the coating process.

  • Patent number: 6385956
    Abstract: A packing yarn and a method of manufacturing a packing yarn composed of at least two bands which are at most 5 mm wide and are joined together by a yarn manufacturing method, include forming the bands of a laminate having at least one layer of flexible graphite and at least one layer of a metal foil with a tensile strength of at least 250 MPa. The layers of graphite foil and metal foil are joined by adhesion or through the use of a non-adhesive-like coupling agent. The bands are produced from the laminates by cutting, which is preferably effected continuously. Advantages thereof are that strips or bands of flexible graphite, which have a tensile strength that is totally inadequate for the manufacture of packing yarns, are altered in terms of their mechanical properties.

  • Patent number: RE37779
    Abstract: In an adsorbing body for humidity and odorous gas exchange such as an adsorbing sheet for dehumidification, an adsorbing element for dehumidification or an adsorbing element for total heat energy exchange, a sheet or a honeycomb laminate is impregnated or coated with silica sol containing, as solid content, not more than 30% of the silica sol weight of minute silica particles not larger than 120 Å in diameter which contain many stable silanol radicals on the surface and 0.01-1% of alkali metal ion Na2O. It is then dried to rigidly fix silica gel. Other humidity adsorbing or absorbing agents such as zeolite, organic high-polymer electrolyte, etc. may be mixed in said silica sol. Silica gel with excellent humidity adsorbing ability can be strongly adhered to a sheet or a honeycomb laminate in an extremely simple method.
