摘要： PROBLEM TO BE SOLVED: To provide a more accurate and rapid behavior analyzing and evaluating method in relation to a process for forming an organic film on the surface of a metal before the synthesis of an organic film compound and a film forming experiment.
SOLUTION: The potential energies in an atomic or molecular unit of the surface of the metal to be analyzed and the organic film on the surface of the metal are respectively calculated on the basis of a molecular dynamic method by a computer to culculate the most stable structures being the minimum energy values thereof. This calculation is performed using a monomer model as a unit in relation to the organic film and performed in relation to the surface of the metal by constructing the periodic boundary model of a crystal state. Next, the total energy value (=the potential energy value of the periodic boundary model of the surface of the metal-the potential energy value of the monomer model of the organic film) of the most stable structure model wherein the organic film and the periodic boundary model are combined is repeatedly calculated on the basis of molecular kinetics so as to be converged to a definite value to simulate the most stable structure model by the computer. When the total energy value is converged to the definite value, the organic film on the surface of the metal is determined to be stable and the bonded state of the organic film at this time of the behavior reaching the bonded state is analyzed.

摘要： PROBLEM TO BE SOLVED: To increase the ratio of columnar crystals in a pipe fitting made of an iron based shape memory alloy, and to improve the fastening force of the pipe.
SOLUTION: In the method of producing an iron based shape memory alloy pipe, at the time when a pipe formed of an iron based shape memory alloy as the stock of a pipe fitting is cast, Ti as an element more easily bonded with N than the case of Al is added to the molten metal of an iron based shape memory alloy in a range where it is bonded with the whole N contained in the alloy, and also the amount of titanium compounds disturbing the formation of columnar crystals is regulated within an allowable range. Thus, the precipitation of AlN on the solidification of the alloy is suppressed to obtain a columnar crystal ratio of ≥50%, so that the inside diameter shrinkage rate of the pipe fitting using the pipe as the stock is increased to improve the fastening force of the pipe.

摘要： PROBLEM TO BE SOLVED: To provide a joining material whose lightening can be attained while maintaining its strength and rigidity, to provide a production method therefor, to provide a structure of a traffic transportation means, and to provide a structure of a railway vehicle. SOLUTION: The joining material 3 is used for a structure of a traffic transportation means such as a railway vehicle. The joining material 3 is a clad plate with a sandwich structure obtained by joining a metal 3a and a metal 3b with an adhesive agent layer 3c. The metal 3a is an alloy bulk material such as an aluminum alloy, a titanium alloy and stainless steel. As the aluminum alloy, the one for elongation is preferable, and a heat treatment type alloy such as a 6,000 series aluminum alloy which has excellent strength and corrosion resistance and can obtain prescribed strength by age hardening is particularly preferable. The metal 3b is a magnesium alloy, and is a magnesium alloy extruded material subjected to extrusion working. As the adhesive agent layer 3c, a powerful adhesive such as an epoxy adhesive is preferable in the case heating treatment is performed after coating. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of corrosion of the section of a pipe and pollution of water, in a coupling part containing the cut pipe of a ductile cast iron line. SOLUTION: A central protrusion 21 of an outside diameter D1 larger than an inside diameter d1 and the annular protrusion 22 of an outside diameter D2 smaller than the outside diameter D1 are integrally molded approximately at the central part of a cylindrical body 2 made of plastic having an outside diameter D0 smaller than the inside diameter d1 of the insertion port of a pipe. An elastic deformed ring 3 forming a truncated conical outer shell expanding throughout an axial arbitrary range extending from two ends 23 is fitted in externally to form an annular hollow part E. The central protrusion forms a stopper at the tip of an insertion port and specifies a connection position. Elastic deformation to absorb the inner peripheral tolerance occurs to the truncated conical outer shell of the elastic deformed ring 3, which is adhered, and water flowing through a pipe is reliably prevented from penetrating a corrosion- proofing core.
