セラミックスの研削残留応力分布のＸ線的研究

The residual stress distribution of ground ceramics was determined from the eigen strain existing in the ground surface. The eigen strain of ground ceramics was tensile, and　exponentially decreased with the distance from the surface. The residual stress distribution is given as a superposition of all exponential function of compression and a linear function. It is found that the actual residual stress distribution call be approximated by a compressive exponential function because the magnitude of tensile residual stress is negligibly small compared to the compressive residual stress. In the experiments, the diffraction angle was measured on ground silicon nitride for a wide range of sin^3Φ using the glancing incidence X-ray diffraction technique. A strong nonlinearity was found in the 2θ-sin^2Φ diagram at very high Φ-angles. From the analysis of nonlinearity, the residual stress distribution was determined. The residual stress distribution of silicon nitride coincided with the distribution calculated from the eigen strain distribution. Transmission electron microscopy was used to clarify the origin of generation of the residual stress. Both strain contrasts and microcracks were observed below the ground surface : straight dislocations were also observed within silicon nitride grains near the ground surface.journal articl

Fashion Perception for Parents and Elementary School Students based on Clothing Life Style

application/pdfFrom the viewpoint of children’s guardians, that is, almost all parents of elementary school-aged students (N=204 boys, 202 girls), we researched what items are requested in the teaching materials on clothing choices in home economics curricula. Next, fashion perceptions and the consciousness and care of clothing by, parents and elementary school-aged students were investigated. The features of the garments’acquisition style (including purchase and delivery methods) for the children's garments were extracted based on fashion perceptions (awareness of styles and their care) of each parent and student. Concerning the teaching materials on clothing life in home economics classes, the parents expressed a strong desire for lessons on "clothing selection, dressing, and care". ’Parents and guardians’ requests for sewing lessons were more common for those with girls than those with boys. The teaching materials on the purchase of garments were not delivered at the elementary school level. Behaviors related to clothing purchases and acquisition by parent and student were examined using the principal component analysis and cluster analysis based on their commonality and dissimilarities regarding perceptions of fashion perception (style consciousness and care). Four similar tendencies were extracted from the parents. A. High fashion perception among both parents and children (parents of 60 boys and 70 girls), B. High fashion consciousness among parents, but low fashion perception by children type (parents of 65 boys and 67 girls), C. Low perception fashion among both parents and children (parents of 21 boys and 25 girls), D. High levels of clothing care among parents and the parents of boys, or a slightly high fashion perception among parents of girls (parents of 58 boys and 31 girls). The behavior differences in parents’ purchase behaviors and the garments’ delivery methods were recognized by parents’ high and low perceptions of fashion. In cases where the children's fashion perception was high, there was a tendency for parents and children to talk about clothes, and they tend to discuss and purchase clothes at stores. Communication between parents and children using clothing is suggested. By contrast, in case where the children's fashion perception is low, the purchase and delivery method of clothing was handled mainly by parents, who often shop in stores and mail-order. The number of these participants was small, but when the fashion perceptions of both the parents and the children were low, the parents showed a greater control over clothing purchase and delivery behavior. We look like the groups where the children don't care about clothes.departmental bulletin pape
