[en] Radial transport is controlled by DC and RF in the HIEI tandem mirror. H-mode-like behavior by limiter DC biasing is created through the formation of radial electric field and sheared rotation. In the case with enhanced radial and axial confinement, high-β plasma (β nearly equals 14%) is attained. Injection of non-resonant RF reduces the peak value of the central cell density and broadens the radial density profile, which leads to the reduction of heat load onto the end plate. 8 refs., 5 figs

[en] We present the clear evidence that the new Fermi surface structure exists in the interconnecting necks of LaB₆, which have been found by the acoustic de Haas-van Alphen effect

[en] The acoustic de Haas-van Alphen effects of CeCu₂, YCu₂ and UB₁₂ have been observed by the sound velocity measurements. The angular variation of the frequencies and the mass enhancement effect are determined. (orig.)

[en] This robot system has been developed for automatic inspection of nuclear power plants. The system configuration is composed of vehicle that runs on monorail, the sensors on the vehicle, an image processer that processes the image information from the sensors, a computer that creates the inspection planning of the robot and an operation panel. This system has two main features, the first is the robot control system. The vehicle and the sensors are controlled by the output data calculated in the computer with the three dimensional plant data. The malfunction is recognized by the combination of the results of image processing, information from the microphone and infrared camera. Tests for a prototype automatic inspection robot system have been performed in the simulated main steam piping room of a nuclear power plant

[en] Resistivity, magnetic susceptibility and magnetization measurements are performed on single-crystal TmTe, which is conducting because of impurities. Some new features were observed with respect to the impurity state in TmTe. ((orig.))
