1.  At the present study, we clarified the power characteristics and the transient response of the power in a small type wind turbine at about 1.1 m diameter of wind receiving area having maple seed type blades in a great wind tunnel experimentally. We have proposed a new type of wind turbine blade having the possibility of easy producing the blades which are imitated the rotation of falling maple seed in the nature world. At the previous study, we dealt with the wind turbine at 0.13 m diameter of wind receiving area. At this case, we clarified the wind turbine has larger power experimentally. At this present, we used maple seed type blades made of CFRP because we kept the blades strength by becoming larger diameter of wind receiving area. We obtained its power and rotation from the wind turbine generator among experimental conditions of the blade installation angle and the blade rigidity. By comparison, they vary by the conditions, and there are the most suitable conditions. We also obtained the result that its transient response to the wind at the maple seed type blade is better than that at the ordinary propeller type blade.
2.  By the application of our developed magnetic intelligent fluid, MCF (magnetic compound fluid) to the silicon oil rubber, we can make the MCF rubber highly sensitive to temperature and electric conduction. It is useful for the element material in haptic robot sensor and et al.. By mixing Cu and Ni particles in the silicon oil rubber and by applying a strong magnetic field to it, it can have high density of magnetic clusters. The formation of the clusters is network, and the phenomena can be confirmed by optical observation. On the other hand, the MCF rubber with iron particles has needle-like magnetic clusters. By comparison between them, the former rubber has more temperature and electric sensitivity than the latter.
3.  This report describes one of several new float polishing techniques with large clearance utilizing a newly developed magnetic responsive fluid, a magnetic compound fluid (MCF) developed by one of authors. In the present study, MCF was improved by the addition of a-cellulose, achieving a large clearance in float polishing. The present study utilized two float polishing tools, each producing a different kind of polishing motion. The polishing results show a finely polished, mirror-like surface with nm-order Ra for various kinds of material. The mechanism of the new polishing technique is explained in terms of a magnetic cluster model. In addition, the MCF float polishing effect is investigated by the fluid behavior on the polishing tool, normal stress, shear stress and behaviors of abrasive and magnetic particles in the fluid experimentally. The MCF float polishing effect depends on the large shear stress and behaviors of abrasive and magnetic particles. The results obtained by this polishing technique are also compared to those obtained using ordinary magnetic responsive fluids, i.e., magnetic fluid or magneto-rheological fluid.
