Since the heliostat is used in harsh environments, its light-concentrating efficiency deteriorates as its precision declines over time. We conducted the comparison examination of gears in order to realize a high light-concentrating precision as well as to minimize the backlash which increases over time. As the result, we adopted the double worm mechanism. We conducted an accelerated test equivalent to 25 years in terms of gear operation distance and in the process, we measured its mechanical precision for each operation equivalent to 5 years. The results of the accelerated test show no change in backlash before and after the test and its maximum values were 0.0001° and 0.001° for the rotation axis and the tilt axis respectively. Thus, we achieved the target of 0.1 degree.In order to automatically compensate for such errors as caused by natural environment or aging deterioration, we studied the system which uses GPS, image recognition, etc. to detect displacements and feed them back to the control. We picked out 16 useful patents and interviewed researchers. As the result, we judged that automatic compensation was achievable.In order to select metal elements and metal thin film formation methods which are effective in biofilm control, we investigated 24 literatures and 12 patents. Also, by using the acceleration device for biofilm formation, we examined the biofilm control effect of metal plate specimens. We picked out 3 types of metal, Ag, Ni and Ti as well as the three thin-film formation methods: vacuum deposition, sputter and application (sol-gel method) as candidates.With Sn and sputter + bake respectively added to the metal element candidates and the metal thin-film formation method candidates, we used 4 metal elements and 4 thin-film formation methods to make specimens and evaluated the biofilm control property. The evaluation was conducted by comparing the degree of deterioration of transmission. The acceleration device for biofilm formation was used for accelerated formation of biofilm on the surface of specimen and its transmission before and after the formation of biofilm was measured/compared to evaluate biofilm control property. The result of the evaluation suggests that Ni and Ti with sputter, Ti with sputter + bake and Ag with zeolite application were good.We made our own sand grain collision test device to verify the durability of the glass specimens.To investigate real marketitions/required performance for commercialization, we held meetings with Mitsui Engineering & Shipbuilding Co., Ltd.
