Long ago the clothing worn by the Ainu race were kera, kap-ur, rap-ur and chep-ur-those of plant, animal skin, bird skin, and fish skin-and since they could get cotton and silk by barter toward the later Edo Era, they came to wear attushi, letarupe, chikar-karpe, ruunpe, kaparamipp, chigiri and mour.I studied how they put them on, consulting the field surveys based on the evidence by the old there. In this first report I wrote of the quantity and the way of their clothing.Their fine garment was usually made by a wife with her greatest effort and affection for her husband as a choice present to him, and he did not own so many as the Japanese today. But they had many ways of wearing; for the ceremony, for daily use, and for laboring. What is more, in another district they wore in another way-for instance, some of them used a girdle on the garment as in the case of kimono and others put the garment over their shoulders like haori. As well as the clothing for the adult, there were those for babies and children and for the dead with their own ways and rules.

A wind power generation has an inherent problem with fluctuation of generation power depending on wind velocity change. This power fluctuation is relating to lesser power quality, then generation power leveling is required. A battery energy storage system is one of countermeasure for suppressing power fluctuation. The battery energy storage system consists of battery, inverter, and control circuit. The better ratio of capacity of the battery energy storage system to the wind power generation, and better control are not shown until now. This paper proposes a better control method of the battery energy storage system for generation power leveling. Simulation studies are carried out and effectiveness of the proposed control is reported.

The microgrid composed of new power generations has been studied recently. The microgrid without utility power system will be examined in the future. We assume the isolated microgrid consists of a synchronous generator and an inverter power source. In this paper the stable operation of the microgrid without utility power system is studied in viewpoint of how larger capacity of the inverter power source compared to the capacity of the synchronous generator can be connected. Moreover, effects on stable operation by different inverter controls are discussed. Result of simulation shows that the capacity of the inverter less than or equal to five times of the generator gives stable operation. And the simulation result shows the application of the voltage control to the inverter will contribute stable operation of the power system.
