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 improve productivity of a powder coating material, and dispersibility of a resin, a pigment, a curing agent and the like which are raw materials therefor.
SOLUTION: The method for producing the powder coating material comprises mixing the resin, the pigment, the curing agent and the like which are the raw materials for the powder coating material, charging the mixed product in a cavity 1a of a mold 1, and repeatedly adding a load to the mixture by punches 2 and 3 from upper and lower sides, that is, by a bulk mechanical alloying (BMA) method to disperse and mix the raw materials. A melting step by heat becomes unnecessary by dispersing the raw materials by the BMA method to enable constrained conditions of the raw materials therefor to be eliminated. Further, the amount of the curing agent is reduced to make the coating operability excellent by increasing the dispersibility of the curing agent. A low-temperature curable coating material can be designed, and a curing agent which can not be used conventionally can be used to widen the width of selection of the curing agent because the melting step becomes unnecessary.

A corrosion-resistant core 7 formed of ethylene propylene rubber (EPR) fitted to the pipe end of the spigot 2a is covered from an outer surface of an end of the spigot so as to reach an inner surface through the end face of the spigot, and fixed thereto. A seal material 20 which is a polyethylene tape 21 with an adhesive surface thereof formed of acrylic adhesive is adhered to an exposed surface of a groove 4a for a spigot ring. The EPR and the acrylic adhesive have no troubles even when they are brought into contact with tap water.
