Self-sufficiency in food is very low (about 40%) in Japan. Therefore, the rice powder is paid to attention because it can be processed to the udon (noodle) and bread etc. We has already developed the rice-powder disintegrator using the underwater sho

IEEE Thirteenth Symposium on Fusion Engineering.
High-power, high-switching-frequency amplifiers have been developed for stabilizing the m=2/n=1 MHD (magnetohydrodynamic) mode of plasma in the JFT-2M to avoid plasma disruptions. The amplifiers are a set of two inverters (INV 1 and INV 2). Each inve
