摘要： PURPOSE:To obtain an oxide superconductor in which the lowering of the criti cal current density due to an impressed magnetic field is remarkably reduced when the magnetic field is impressed parallel with the c axis of a crystal. CONSTITUTION:The hole density of an oxide superconductor with the hole as a carrier is higher than the density of the hole giving the highest superconducting transition temp. of the oxide superconductor. The superconductor is heat-treated in an oxidizing gas atmosphere or the cation except copper constituting the superconductor is substituted by a low-balancy ion to make the density higher than the optimum value giving the maximum Tc. Consequently, the lowering of the critical current density due to an impressed magnetic field is minimized when the magnetic field is impressed parallel with the c axis of the crystal, and the superconductor having a high critical current density is produced.

摘要： PURPOSE:To obtain an oxide superconductor high in volume ratio and low in impurities by placing a molding made of a powdery raw material of the oxide superconductor in a pressure resistant member, reducing the pressure to low and heat-treating in a prescribed condition. CONSTITUTION:The powdery raw materials of the oxide superconductor (e.g. Pb based 1212 type) are mixed in a stoichiometric mixing ratio and molded and the molding is inserted into a pipe made of a noble metal such as gold and is placed in a 1st pressure resistant member (e.g. a quartz ampule, a pipe made of metal, the inside of which is evacuated to 1X10 to 1X10 Torr and is sealed. Then the molding is heat-treated at 950-1050 deg.C for >=10 hours and slowly cooled at about 1 deg.C/sec cooling rate. Next, the molding is placed in a 2nd pressure resistant member, the inside of which is evacuated to 1X10 to 1X10 Torr and sealed, and is heat-treated at 800-950 deg.C for 10 hours. Next, by dipping the pressure resistant member into liquid nitrogen or rapidly cooling or by left standing in air, the oxide superconductor having a higher volume ratio of about 40% and small in impurities is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a neutron diffracting device capable of detecting scattered neutrons by irradiating a neutron beam locally to a measuring sample, acquiring Bragg reflection data by moving the measuring sample successively, and performing observation by mapping acquired data. SOLUTION: A neutron beam for observation led out from a neutron source is allowed to pass the first slit, and guided into the second slit through a guide pipe formed from a neutron mirror, to thereby narrow the diameter of the neutron beam to be irradiated to the sample. A plurality of detection pipes for detecting scattered neutrons are aligned on a circular arc centered at the sample, and each shielding plate facing to the center is provided between each detection pipe. While moving a stand on which the measuring sample is placed at each prescribed interval by a moving mechanism, data of the detection pipes are acquired, and mapping data are acquired.

摘要： PROBLEM TO BE SOLVED: To provide a method for diagnosing a degradation of a steel framed structure, which can easily and precisely inspect a defect such as a corrosion or the like existing inside a wall of the steel framed structure through the outer surface of the wall.
SOLUTION: A defect detecting device is equipped with magnetic impedance effect elements being arranged in parallel and each having a bias field coil and a plurality of detecting channels each of which detects an output of each element through a detector circuit. A surface to be inspected of the steel framed structure is scanned with the magnetic impedance effect elements being kept close to the surface to be inspected, by using the defect detecting device. The wall of the steel framed structure becomes a portion of a magnetic field circuit which is the bias field generated by the bias field coil, and the strength of the bias field varies in accordance with the degree of corrosion/reduction in the backside of the wall, and changes in outputs of the magnetic impedance effect elements correlate with the degree of corrosion/reduction in the backside of the wall. Therefore, the degree of corrosion/reduction in the backside of the wall can be determined from the changes in the outputs.

摘要： PROBLEM TO BE SOLVED: To properly detect flaws of a magnetic metal body, using a magnetic impedance effect type sensor by a leakage magnetic flux flaw detecting test method, and moreover, properly miniaturizing a magnetic detector.
SOLUTION: The magnetic detector, which has a coil for applying magnetic field to the metal body and the magnetic impedance effect type sensor for detecting the leaking magnetic flux at the flaw location of the metal body, is moved to the inspection region of the surface of the metal body; while the magnetic field for demagnetization or magnetization is made to act on the inspection region of the surface of the metal body, to uniformize the magnetized state of the metal body and the surface of the metal body is scanned by the magnetic detector, while applying a flaw-detecting magnetic field to the surface of the metal body by the coil, to detect the flaw of the metal body by the magnetic impedance effect type sensor. Since the flaw of the metal body is detected by using the magnetic impedance effect type sensor by the leakage magnetic flux flaw detecting test method, after demagnetization or magnetization method, the effect of the leaking magnetic flux noise due to residual magnetism is excluded, and the flaw location of the metal body can be detected with original high sensitivity that is based on the magnetic impedance effect.
