The paper stated mostly topics from special lectures. Composite materials have a lot of potentialities, and there are larger expectations in flexible and high-strength soft composites rather than the conventional high rigidity ones. As to micro-machines, the problems are on mechanical property of the element, environment/friction/fracture/life, etc. and the evaluation method of the characteristics was studied. Concerning the research and development of the intellectual structure system, the introductive study has entered the second year. Ultimately, structures have functions similar to those of the living organism had, and conduct self-diagnosis, self-repair and autonomous-response. Railroad structures receive regular inspections according to the rule, and a half of the objects for the inspection are cracks, unbonding and weathering of concrete. With the Hanshin Awaji great earthquake especially, the anti-earthquake reinforcement has been expedited. In various kinds of materials, the finer the crystal particle becomes, the greater the high temperature deforming ability becomes. When the particle size is below the critical particle size, it shows superplasticity. The study is advancing. As to high density secondary batteries, introduced especially were Ni-hydrogen batteries and Li batteries.

G-5 and 6 measure and investigate actual state of use of hot water supply systems in dormitories used by persons living alone without their families and by unmarried persons to collect fundamental data. G-5 considers how hot water is used, by making a questionnaire survey on the subject houses, and identifies the consumption trend of heat, water and hot water in the hot water supply systems as a whole. G-6 selected eleven houses from among the houses discussed in the previous report to identify the trend of use of hot water by each house. Also, quantity of hot water used in every day of the week is estimated. G-7 discusses methods for estimating water temperatures at faucets of water pipes from the water sources. This is intended to raise the accuracy of tap water temperature conversion coefficient by districts used for calculating estimated heat quantity as a parameter 'hot water supply energy consumption coefficient' to evaluate energy saving performance of a hot water supply facility. G-8 performs numerical simulations changing different parameters in the hot water supply piping system by using a heat loss calculation model for the existing household hot water supply piping. It executes evaluation on energy conservation performance of each model. G-9 estimates efficiency of instantaneous household gas hot water supply devices, not only on thermal efficiency of devices during steady state combustion, but also on non-steady state such as start-up, and discusses methods to derive actual efficiency by using calculations.
