Kyo-gawara is one of traditional crafts, one of Japanese roof tile made in Kyoto by using traditional techniques. The characteristics of Kyo-gawara is gloss on surface available in “Migaki” process. Migaki process is that craftsman strokes half-dry surface with paddle one by one. Number of products that a craftsman has to finish the process is decided. In previous study, investigation about the relationship between number of times of Migaki process and surface properties of Kyo-gawara cannot be seen [1]. In this study, specimens having different number of time of Migaki process (none, once, twice) were used, surface structure and properties were analyzed, and investigation about the relationship between Migaki process and surface characteristics was performed. Measurement items are surface roughness (Ra), contact angle, water absorption. As a result, surface roughness tended to decrease, and with increase of number of times of Migaki process. From the result of measurement of contact angle and water absorption, it was clarified that Migaki could improve waterproofness.

Interstitial Elements

Addition of interstitial elements to γ-TiAl alloys is currently being explored as a method for improving the properties of these alloys. Previous work in which a number of interstitial elements were studied showed that boron was particularly effective in refining the grain size in castings, and led to enhanced strength while maintaining reasonable ductility. Other investigators have shown that B in γ-TiAl alloys tends to promote the formation of TiB2 as a second phase. In this study, the microstructure of Bcontaining TiAl alloys was examined in detail in order to describe the mechanism by which B alters the structure and properties of these alloys.

Macromolecular Systems

The most advanced macromolecular materials are found in plants and animals, and certainly the connective tissues in mammals are amongst the most advanced macromolecular composites known to mankind. The efficient use of collagen, a fibrous protein, in the design of both soft and hard connective tissues is worthy of comment. Very crudely, in bone collagen serves as a highly efficient binder for the inorganic hydroxyappatite which stiffens the structure. The interactions between the organic fiber of collagen and the inorganic material seem to occur at the nano (scale) level of organization. Epitatic crystallization of the inorganic phase on the fibers has been reported to give a highly anisotropic, stress responsive, structure. Soft connective tissues also have sophisticated oriented hierarchical structures. The collagen fibers are “glued” together by a highly hydrated gel-like proteoglycan matrix. One of the simplest structures of this type is tendon which functions primarily in uniaxial tension as a reinforced elastomeric cable between muscle and bone.

High Oxidation Resistance

Recently, the use of refractory metal silicides as low resistivity, high temperature and high oxidation resistance gate materials in large scale integrated circuits (LSI) has become an important approach in advanced MOS process development (1). This research is a systematic study on the structure and properties of molybdenum silicide thin film and its applicability to high performance LSI fabrication.
