 note = {The authors have developed several reduced gravity devices based on the yo-yo principle, and their effectiveness is demonstrated by the various educational experiments. On the other hand, several points to improve are revealed for more public uses. This paper reports a newly developed device combining two pulley systems separating the yo-yo repulsion pulley and the spiral pulley modulating the rotational speed. A cozy design is resulted from those improvements, in addition to the remarkable reduction of the repulsion shock., 資料番号: AA0063706025},
