This R&D aims to collect and separate aluminum-containing waste materials (general waists and industry waists), and recover highly-pure aluminum by the efficient dry distillation process. By using the cartridge system (containing the aluminum and reactant), hydrogen energy is generated for variety of applications. This system contributes the improvement of aluminum material flow and provides low-carbon solutions. In this paper, relation between concentration of NaOH and hydrogen generation rate was researched. It was found that 4% NaOH was optimum for hydrogen generation rate. Moreover the effect of inorganic salts on hydrogen generation was researched. As for the result, it was clarified that reaction liquid with FeSO4 could promote hydrogen generation.

It is known that there are periodic water level fluctuations off the coast of Toyama Wan. Investigation on the periodic water level fluctuations was carried out to prevent wave disasters by wave observations and wave generating experiment. Water levels were observed at three points of Toyama New Port, Iwasehama and Iida Wan. The water level fluctuations with the periods of about 10 minutes or more were investigated using the water level data observed at the three points and wave generating experiment data.The results of this investigation are:(1)The water level fluctuations with the periods from about 10 minutes to about 1 hour are proper oscillations driven by water level fluctuations due to moving low atmospheric pressure or earthquake, in horizontal shallow water off the coast.(2)Proper oscillation with the period of about 36 minutes between the Toyama coast and the southern coast of apex of Noto peninsula, causes a beat phenomenon with the same period as the proper oscillation period to swells which invade Toyama Wan from north.(3)There is greater tsunami risk on the coast of Iida Wan as compared with the Toyama coast.

Heat transfer enhancing method is more and more needed to decrease power consumption. This study was carried out to develop a high performance vortex generator, and find out the relationship between vortex structure and heat transfer. Double delta winglet pair was developed to reduce pressure drop with keeping up vortex strength. It was clarified that double delta winglet pair had higher performance than delta winglet pair by 10% at flow velocity of 1.4m/s by measuring average heat transfer coefficient and pressure drop. It was found out that double delta winglet pair had the position of vortex core at short distance from heat transfer surface than delta winglet pair. Therefore, the heat transfer coefficient was larger than delta winglet pair's one, even though it's vortex strength was smaller than that.

The upbringing of creativity, problem-identifying ability, problem-solving ability, and planning ability of engineers by using logical thinking is one of important problems for developing products in Japan. The upbringing of above abilities by using logical thinking is required for graduation research and master research in university. Therefore the authors planned and practiced the new subject “Advanced Exercises for Creative Designing toward Problem Solving” that performed master research by using logical thinking. In this education subject, students performed the investigation of conventional studies, the examination of problem-solving method, the planning of research and the conduct of research about their master researches by using logical thinking methods. The results of the questionnaire made it clear to be able to bring up creativity, problem-identifying ability, problem-solving ability, and planning ability by attending the subject.
