We have developed a low-speed and low-capacity wind power generator. In this paper, we introduce the outline of the 5kW multi-polar synchronous generator that generates the electric power efficiently from 50rpm to 180rpm. The generator is produced by a magnetic powder core for cost reduction. We also express the outline and field test results of the low-capacity power plant constructed in Ohmura City, Nagasaki.

This paper proposes a heat capacity identification method for cooking household appliances. Cooking household appliances select a cooking flow according to a cooking object capacity, hence the heat capacity identification is a very important function. However, a conventional heat capacity identification method has been based on one variable using "if-then rules", hence it gives a low accuracy. This paper proposes a new heat capacity identification method that uses Mahalanobis-Taguchi System which is similar to discriminant analysis, and the effectiveness of this method is confirmed by the experiment.

This paper proposes an available method of obstacle avoidance control by using a single CCD camera and ultrasonic sensors mounted on the mobile robot. First, depending on the change of the brightness on the image that occurs from the moving of the mobile robot, we calculate the optical flow by the block matching method based on the normalized correlation and detect the obstacle area on the image. Further, in order to reduce the error of the detection area, by combining the distance information obtained by ultrasonic sensors on the image shown the obstacle area we decide the position of obstacle with high accuracy. Dealing with the position information, we make the reference points for generating the trajectory of the mobile robot. This trajectory is smooth and is generated by minimizing a certain cost function. Then, the mobile robot moves according to the trajectory while avoiding around the obstacle. Finally, usefulness of our proposed method is shown through some experiments.
