IPC: G01B15/08
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for inspecting the corrosion state of the surface of a metal material such as a steel plate and a pipe from an area on a coating film or a lining coating by utilizing the reflection of X rays. SOLUTION: In this method, X rays are applied to the surface of a coated or lined metal 1 which is under the coating film of the metal or a lining coating 2 at an angle of 70-100% in terms of a reflection dose intensity ratio, a reflection dose ratio for incident X rays 5 is measured. Further, the roughness of a metal surface is measured based on the relationship between the reflection dose ratio of X rays and metal surface roughness obtained in advance according to the dose ratio. Then, based on the relationship between the metal surface roughness and the degree of corrosion obtained in advance from the roughness of the metal surface, the presence or absence of corrosion and the degree of corrosion on the metal surface under the paint film are inspected.

Title: Black crystallized glass having excellent machinability and production thereof
Inventor: MAKISHIMA SUKEO
IPC: C03C10/00
Filed: 1988-11-16
Abstract: PURPOSE:To obtain a black crystallized glass imparted with excellent machinability without using crystalline mica by melting a composition containing SiO2, Al2O3, Y2O3, CaO, CoO and further Fe2O3 or CuO and allowing the molten composition to cool. CONSTITUTION:The objective crystallized glass can be produced by (1) melting a mixed composition composed of 60-40mol% of SiO2, 6-16mol% of Al2O3, 6-16mol% of Y2O3, 15-30mol% of CaO, 0.8-2.0mol% of CoO and 0.8-2.0mol% of Fe2O3 and/or CuO and (2) allowing the molten material to cool to precipitate acicular fine crystals of Ca4Y6(SiO4)6. The black crystallized glass produced by the above process can be further crystallized if necessary by heat-treating at 900-1400 deg.C. In the case of using the glass as a material for absorbing stray light by forming a black evaporation film on an optical instrument, the stray light-absorbing effect can be improved by using the black crystallized glass having irregular surface.

Abstract: PURPOSE:To manufacture a high density and high reliability printed wiring board also with a short processing time by forming a necessary negative pattern on the surface of a copper-clad laminate through the use of a resist soluble in an aqueous alkaline solution and by forming an etching resist film composed of 2- alkylbenzimidazole compound. CONSTITUTION:A necessary negative pattern is formed on the surface of a copper-clad laminate through the use of a resist soluble in an aqueous alkaline solution, the copper- clad laminate is brought into contact with an aqueous acid solution containing 2- alkylbenzimidazole compound so that an etching resist film is formed on the copper surface, and after the negative pattern film is removed, the copper-clad laminate is brought into contact with an alkaline etchant so that the resist film is peeled off. When the aqueous acid solution containing 2-alkylbenzimidazole compound is brought into contact with copper, a stable chemical conversion coating containing a benzene ring conjugated by both actions of a complex formation reaction and hydrogen bond and van der Waals force is formed on the copper surface. When the coating is dried by heating, a certain kind of polymerization reaction occurs in 2-alkylbenzimidazole- copper complex to produce a hard chemical conversion coating having an excellent resist action.
