X-ray fluorescence analysis is one of the methods commonly used to reveal whole-rock chemical composition, which is basic information of rock samples. This report shows methods to prepare glass beads of fused samples and to use the X-ray fluorescence spectrometer (Rigaku ZSX Primus II) housed in Tono Geoscience Center, and the evaluation of precision and accuracy of the measurement.

Times Cited Count：3 Percentile：14.26(Engineering, Chemical)Anchored osmotic pressure inducer was examined. Salt-containing filter paper attached to an osmotic membrane increased the water flux to more than 10% at 1 MPa. The salt-containing filter paper was fabricated via graft polymerization of acrylic acid onto a filter paper followed by alkaline treatment. The filter paper was characterized by thermo gravimetric analysis (TGA), attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), scanning electronic microscopy-energy dispersive X-ray spectrometry(SEM-EDS).

Relaxation process of surface compressive residual stress during tensile or compressive loading on a laser peened aluminum alloy was investigated. The residual stress was measured by X-ray, synchrotron and neutron diffractions and analyzed by a finite element method. The relaxation process clarified in this study was described as follows. When the tensile loading was increased, plastic deformation was occurred at the tensile residual stress region that existed inside of the material to be balanced with the surface compressive residual stress. On the other hand, when the compressive loading was applied, the plastic deformation was started at the maximum compressive residual stress region located just beneath the surface. Because the plastic deformation of the inside of the material induced the redistribution of the residual stress in the sample, the surface compressive residual stress was relaxed prior to the surface yielding.

Effects of compressive residual stress on fatigue strength on a laser peened aluminum alloy were investigated. The changes of the compressive residual stress were measured using X-ray diffraction. The residual stress was relaxed at the first loading cycle and after that the residual stress was almost kept until the final fracture. The number of fatigue cycles to failure could be predicted quantitatively if the compressive residual stress after the first loading cycle was estimated.

Recently, development work of man-machine interface is being performed in many fields of nuclear power plant operation design from the viewpoint of "Operational Safety". Out of the many man-machine interface works, development of operation guide system for supporting operator's judgement on the plant condition is considered as an important work. The aim of this development work above is to improve cooperation between man and machine in the point of their interface by offering necessary and appropriate information to operator according to the plant condition. In this design, it is intended to ensure man-machine communication positively, and the preliminary design of the following items was performed in relation to operation guide system which aims at improvement of operation property of fast experiment reactor "JOYO". (1)Plant condition supervisory function. (2)Plant condition diagnosis function based on the knowledge data base. (3)Plant condition diagnosis function based on the experience data base. (4)Information display function and conversation function. (5)Hardware system configuration. This operation guide system intends to apply to "JOYO" finally. As the previous step, it is planned to verify with "JOYO" training simulator. And in this design, the interface between simulator and this system, and the items of reconstruction of simulator is also investigated.

In this study, the intergranular effect generated in a laser peened surface of a ferritic steel was evaluated using neutron diffraction. The residual stress distribution from the surface to 1 mm depth was obtained by the strain distributions measured using the 110, 200 and 211 reflections. The residual stress distributions derived from the strains of the 110 and 211 reflections were good agreement, while that of the 200 reflection, which is sensitive to the intergranular effect, indicated larger compressive stress by 100 MPa to 200 MPa in the surface layer until 0.8 mm depth from the surface. It is probably intergranular effect, so that the residual stress measurement with consideration of the intergranular effect may be required to evaluate the residual stress generated in the surface layer of the surface treated sample such as the laser peening, the shot peening and so on.
