The one of Japanese traditional Town-houses called "Nagaya" is characterized by the stores and houses on a street of pre-Modern and Modern Osaka City exceedingly. Those have repeated enlargement and renovation at the complicated modernized situation in Osaka, and yet some of them have continued to exist. The purpose of this study is to extract mechanism of change from chronological simulation based on 'Tipologia Edilizia', and to recognize necessary conditions of continuation. As a result, We found that the owner and residents have continued the maintenance based on weak traditional system in spite of under the situation of inevitable modenization.

Fluorescent liquid penetrant test equipment, for testing welded parts of the evaporator for phosphate liquid waste generated by solvent waste treatment at Tokai Reprocessing Plant, was developed. It is composed of a CCD camera and UV light for observation, nozzles for fluorescent liquid, water for washing, and air for drying, and a positioning mechanism that can adjust the position of this equipment relative to the inspection object by three-axis operation, varying the insert length, bending angle and turn angle. Also, the equipment can be inserted by way of the nozzle for inspection, whose inside diameter is 60 mm, into the evaporator. It was confirmed that the standard faults, as defined in JIS, could be observed by the equipment. Then, a fluorescent liquid penetrant test of an evaporator that has treated phosphate liquid waste for 18 years with a heating temperature of about 105°C was performed. The result of the test indicates the absence of faults in the evaporator.<br>

Spanwise eddy diffusivity of heat was measured in a flat-plate turbulent boundary layer with a constant spanwise temperature gradient and different intensities of free-stream turbulence. Comparison was made with the usual kinematic eddy viscosity measured in parallel. According to the experimental results, the ratio of these eddy diffusivities is strongly influenced by the free-stream turbulence. However, in the vicinity of the wall, this ratio approaches a certain universal distribution which is independent of the intensity of free-stream turbulence.

保冷コンテナを改造した貯雪庫に約4ヶ月間雪を保存した後に、その底部に水を流して冷熱を取り出す実験を行った。その結果、(1)雪を長期保存することでその強度が増すため、貯雪底部の融解が進んでも貯雪の崩れや割れが起こりにくくなり、水の冷却性能が低下すること、(2)貯雪に崩れや割れが発生すると、水の冷却度合いが急に増加すること、(3)水の冷却性能は貯雪庫内の水位が高いほどが高いが、水位10cm程度で飽和することがわかった。
