It is designed to not lose the magnetic repulsive force such that equipment traveling at high speed can be safely transferred at least to the nearest station. In addition, electromagnetic levitation traveling equipment on which the above-described apparatus is installed and a control method therefore is also described.

摘要： A track vehicle such as a Maglev train has a body with superconducting coils mounted thereon which superconducting coils interact with vertically extending coils on guideways of a track to generate a propulsive force. The vehicle runs on wheels at low speeds but at higher speeds the superconducting coils may interact with ground coils to generate a lifting force. In order to reduce or eliminate stresses between the superconducting coils and the vehicle body, the vehicle has one or more wings of airfoil shape which generate lift. That lift may be sufficient to support the whole of the weight of the vehicle, enabling the ground coils to be eliminated. Furthermore, the shape of the superconducting coils may be changed so that they supply more energy to propulsive effects. Preferably the angle of incidence of the wing(s) is variable, to permit the lift generated thereby to be varied. This variation in the angle of incidence may be controlled by a sensor detecting the height of the body above the track, to maintain that height constant.

摘要： An object of the present invention is to solve the bending of an NMR probe and a room temperature shim coil so that they can be positioned easily. In the NMR spectrometer including split-pair magnets and a cross bore, a high rigidity straight pipe to which an NMR probe and a room temperature shim coil are attached so as to make an integral object, is provided. The outer diameter of the straight pipe is smaller than the inner diameter of a horizontal bore into which the room temperature shim coil and the probe are inserted. After the room temperature shim coil and the NMR probe are attached to the straight pipe by bolts, respectively, the integral object is inserted into the horizontal bore (a room temperature space) of the NMR spectrometer. The room temperature shim coil and the probe may be attached to different straight pipes.

摘要： In NMR system, for preventing a temperature gradient which causes a decrease in S/N ratio from being created in a sample area while suppressing deterioration in homogeneity of a magnetic field, a thermal conductor having high thermal conductivity is disposed in a room-temperature shim coil. The thermal conductor is provided as a coil bobbin, the temperature of the thermal conductor being controlled by a temperature controller using a heat exchanger. Temperature control gas, which is adjusted to a temperature equal to that of the room-temperature shim coil, is fed from the downside of a sample tube, and it is possible to suppress a temperature gradient from being created in a sample area. According to the present invention, since the temperature distribution can be made to be uniform so as to avoid creating a temperature gradient in the sample area while suppressing deterioration of homogeneity in the magnetic field, the NMR spectrum is sharpened so as to improve the S/N ratio.
