Patent JP-H08271769-A (JP)
Title: Optical product
Inventor: MAURIIN JIREN CHIYAN
IPC: C03C25/10
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber resistant to degradation caused by both wear and corrosion in high temperature and high humidity environment. SOLUTION: An optical fiber has a thin pseudo metallic oxide film 106 (about 10nm in depth) and a protective polymer layer 108 around a core clad layer assembly. Over many years, a first applied reactant of the thin film is oxidized or hydrolyzed particularly under the influence of high temperature so as to form the thin pseudo metallic oxide film on the surface of a clad layer 102. The thus formed pseudo metallic oxide film 106 hinders a surrounding fluid from reacting on the surface flaw of the clad layer of the optical fiber. Corrosion is thereby delayed by a large margin so as to improve mechanical performance and reliability of the optical fiber. The pseudo metallic oxide film 106 also protects against wear. The reactant for forming the pseudo metallic oxide film can also be led into a filler of an optical fiber cable.  The reactant thereby permeates the protective layer and reacts on the surface of the core clad layer.

Title: Electrolyte liquid for electrolytic capacitor
Inventor: MINAMI SHINICHIRO
IPC: H01G9/035
Filed: 1992-02-26
Abstract: PURPOSE:To enhance the properties of an electrolyte to a satisfactory extent over a wide temperature range and prevent the generation of outside visual expansion in a high temperature ambient atmosphere in a solder reflow furnace or the like by melting an organic acid or its salt in a solvent solution which uses cyclamenaldehyde as its main substance.
