Title: Production of plastic article of high gloss and light color
Inventor: RICHIYAADO AISUFUERAA
IPC: C23C14/06
Filed: 1993-12-03
Abstract: PURPOSE: To produce a high gloss bright colored plastic product by successively forming a colored primer, a transparent basecoat and discontinuous islands on a substrate and forming a light transparent topcoat thereon.  
     CONSTITUTION: The substrate 10 (injection molding grade thermoplastic polyurethane or the like) is successively coated with the colored primer 12 (urethane) and the transparent basecoat 14 (light transparent urethane enamel). The island layers 12 (thickness about ≤100 Å) consisting of the discontinuous indium islands are formed on this basecoat 14 by vacuum vapor deposition. The smaller islands are removed by etching the island layers 21 to increase spaces 22. The island layers 21 are coated with a topcoat 24 of a light transparent liquid and the basecoat layer 14 is wetted via the spacers 22, by which the basecoat layer is directly bonded and cured, thereby the protective coating is formed. As a result, the substrate 10 coated with the high gloss colored coating having the gloss class within a range of 60 to 200 is obtd.

Title: Propellant
Inventor: ANDO HIDEKAZU
IPC: C06D5/00
Filed: 1990-11-30
Abstract: PURPOSE:To increase the specific impulse and density of a propellant and suppress the temperature increase of combustion gas by using a hydrogen-storage alloy in combination with an oxidizing agent. CONSTITUTION:A propellant is produced by compounding 2-35% hydrogen- storage alloy and remaining part of an HTPB binder and an oxidizing agent. As an alternative, a propellant is produced by using 30-90% hydrogen-storage alloy, a liquid oxide and a fuel containing a small amount of a solid oxidizing agent. When the propellant is burnt, hydrogen gas is released from the alloy according to the rise of the alloy temperature and a part of the hydrogen gas is reacted with an oxidizing agent component generated by the decomposition of the propellant. The metallic alloy left after the release of hydrogen is gasified according to the ambient temperature increase and reacted with the oxidizing agent component generated by the decomposition of the propellant to generate high heat of combustion. Although a part of the hydrogen gas released from the hydrogen-storage alloy is reacted, the remaining part of the hydrogen is left unreacted to contribute to the lowering of the molecular weight and the gas temperature.
