  • Publication number: 20010014390
    Abstract: A method for fabricating an object to attenuate thermal sensation when handling the object at non-body temperature, and an object fabricated in accord with the method. There is first provided a substrate which has a first surface subject to handling. There is then formed upon the first surface of the substrate a coating. The coating has an optimal density, an optimal thermal conductivity and an optimal thickness such that when the substrate having the coating formed thereupon is equilibrated at a non-body temperature differing from a body temperature and the coating is subsequently contacted with a body at the body temperature during handling, the temperature of the surface of the coating at a contact point of the body with the coating changes precipitously to a temperature near the body temperature and subsequently returns towards the non-body temperature at a rate which permits handling of the coating at the location of the first surface of the substrate by the body with attenuated thermal sensation.

  • Publication number: 20010008693
    Abstract: A multilayer dielectric film structure includes a pair or plurality of materials at least one being a polymer and the other of high index of refraction inorganic material (compared to the polymer) at the wavelengths of interest. The structure is fabricated by a combination of layering techniques, one of which is used to create a layer of the polymer, the other being used to deposit the inorganic component. The assembly process yields a structure of alternating polymer and inorganic layers of high index of refraction (compared to air). The structure preferably will reflect light within a certain frequency range of any polarization and at a continuum of angles of incidence ranging from normal to oblique. In a particular embodiment of the invention, the structure includes alternating layers of a polymer, e.g., polystyrene and Tellurium.

    Abstract: A mixture of two stabilizers, one including benzene rings bearing hydroxyl substituents and the other containing divalent sulfur atoms, is effective in stabilizing tacky polymers that remain solid up to a temperature of at least 160° C. particularly polymers of isobutylene, so that the polymers give long service in the ambient atmosphere as protective layers coated on aluminum substrates and used to line the interiors of paint baking ovens. When accumulated foreign materials accumulate on the coatings, the coating and the accumulated foreign materials can be decomposed to largely volatile products by heating to a temperature substantially higher than the service temperature but not high enough to melt the metal substrate for the coating.

  • Patent number: 5837354
    Abstract: A flexible metallized product having a base material made of a soft resin material comprising polypropylene mixed with diene or polypropylene mixed with rubber, a base coat layer formed on the surface of the base material, a metal thin film layer formed on the surface of the base coat layer and a top coat layer covering the metal thin film layer. The metal thin film layer is made of a corrosion resistant metal such as chromium. The metal thin film layer has a thickness of at least 150 .ANG. and no greater than 800 .ANG. by means of a vacuum vapor deposition or sputtering. The metal thin film layer is constituted by a plurality of metal particles. The metal particles are disposed such that adjacent metal particles are in contact with one another to form a grain boundary therebetween.

  • Patent number: 5759683
    Abstract: A holographic article and method for forming permits the party producing the final document to print the holographic image directly on the final document thereby permitting such party to retain and maintain control of its own embossing shim on which the hologram has been formed and which is utilized for embossing the holographic image on the document. A film upon which a holographic image can be directly stamped upon the final document includes a layer of metal having a thickness in the range of 20 millimicrons to 100 millimicrons, a lacquer coating having a thickness in the range of 0.5 microns to 3 microns and a heat activatible adhesive. The metal layer lacquer coating and heat activatible adhesive are caused to be adhered to the substrate forming the final document during a stamping operation which releases said metal layer, lacquer coating and heat activatible adhesive from a plastic carrier film to which had initially been applied.

  • Patent number: 5712003
    Abstract: Provided is a blow-molded article which can be readily formed with good Gloss and with substantially no surface unevenness, even without application of surface coating, and which can be used as a finished product without further treatment. The blow-molded article has a base layer and a surface layer. The base layer is formed from a thermoplastic resin material having a melt index (MI) of about 0.05-2.0 and a flexural modulus of 1,470 MPa (15,000 kgf/cm.sup.2) or more. The surface layer is formed from a colored or transparent thermoplastic resin material having an MI of about 1-30 provided that it is higher than that of the base layer, and excellent weather resistance. The thermoplastic resins used to form the base and surface layers should be resins of the same family.
