In surface fabrication process, such as the polishing in semiconductor substrate, there are many nano-particles moving on or nearby the surface to be polished. We have been establishing an optical method to observe and to track the 3-dimensional position of each dynamical moving nano-particle on time by applying an evanescent light field. In this report, the scattering light characteristic from a moving nano-particle in an evanescent field generated by internal reflection on a silica glass surface was analysed by FDTD (Finite Difference Time Domain) method on MATLAB. We discuss the scattering light from a particle moving perpendicularly to a surface in an interval time as one recorded frame in practical observation.

Ingot annealing process is indispensable for compound semiconductor single crystals such as GaAs and InP to improve their electric characteristics. One of the technical problems of ingot annealing is increase of dislocation density that affects the performance of electronic devices. A computer code was developed for the dislocation density evaluation of a single crystal during ingot annealing process. A dislocation kinetics model called the Haasen-Alexander-Sumino model was used as a constitutive equation. In this model, creep strain rate is related to the dislocation density, and this model was extended to the multiaxial stress state based on the theory of crystal plasticity. Three-dimensional finite element model was used to take account of crystal anisotropy in elastic constants and specific slip directions. The authors improve the creep constitutive equation to take account of dislocation annihilation. Dislocation density analyses during ingot annealing process were performed for an InP single crystal with 101.6mm in diameter. The distribution and time variation of dislocation density were obtained from this computer code.

The technical committee of ISO/TC197 Hydrogen Technology was founded in 1989 in conjunction with the world social demand for hydrogen energy activities. The committee is a personal volunteer work. The number of the P-members is now 18 and The number of the O-member is 19. Only one private organization is allowed to participate in the committee as either P-member or 0-member. In Japan, JISC is officially registered as one of the P-members. The committee has already finished settling two 180 standards; ISO 13984 “Liquid hydrogen-land vehicle fuelling system interface” and ISO 14687 “Hydrogen fuel-product specification”. Eight items are now under process toward the ISO standardization.

The present activities is introduced by using OHP slides in this HESS Meeting.

This work extends the applicability of a recent variational model that has been used for analyzing laminates to determine the stress state in a laminate with alternating material properties in the longitudinal direction subject to tensile and bending loading. For simplicity, a plane stress problem was assumed in this study. The laminate was subdivided in the longitudinal (tensile loading) direction as in the previous analysis. In addition, the laminate was subdivided in the thickness direction by using the ply refinement technique. To introduce the ply refinement technique and to account for continuity boundary conditions between divided regions in the loading direction, the Lagrange multiplier strategy was used. Closed form expressions for the energy function derived from using the strategy led to a very concise solution for determining the approximate stresses in the laminates. As an example, a laminate with ply discontinuity was analyzed, and the resultant stress distributions were then compared to the previous variational analysis model and finite element method (FEM). Compared to the previous analysis, stress concentration at the region interfaces could be captured, and excellent agreement between FEM was demonstrated.

This paper aims at acquiring the effective knowledge in connection with a defined function of a Kouminkan. A viewpoint is considered on the side of a defined function of the actual condition of the program of a Kouminkan. The result of analysis, social education facilities and central facilities of an area take up as fundamental character of a Kouminkan. As an element which should be examined for the planning of a Kouminkan, the social education function as a social education facilities, the local self-government function and a community welfare function as a central facilities of an area are raised.

Tests on reinforced concrete exterior beam-column joint sub-assemblages with low column-to-beam strength ratio in the range commonly constructed in practice are reported. Story shear capacity of some specimens were 30% lower of the story shear predicted by the flexural strength of the beam or the column at the maximum, although the joints have enough margins for nominal joint shear capacity by 10% to 50%. The decrease of story shear is larger in the case of the column-to-beam strength ratio is equal or near to unit. Column-to-beam strength ratio required to secure lateral strength predicted by the flexural strength of sections is small in the case of that the amount of transverse reinforcement in the joint is large, the column depth is large relatively to the beam depth or bent bar anchorage is used instead of mechanical anchor with headed bars.
