摘要： The vehicle is powered by a linear synchronous motor, The linear synchronous motor comprises a series of field poles fitted on the vehicle body along its total length and a series of magnetic devices being provided along a track on the ground facing these field poles and developing a travelling magnetic field. A driving force developed between these field poles and the magnetic devices causes the vehicle to move.Such a linear synchronous motor powered vehicle has a problem when securing proper and satisfactory places to mount the necessary equipment of the vehicle. The problem arises from the peculiar construction thereof that a plurality of field poles are disposed along the entire length of the vehicle body.A satisfactory mounting of the apparatus may be attained by a unique arrangement of the field poles, without making the vehicle body large in size or providing discomfort to the passengers.

摘要： An electric rotary machine having a superconducting rotor, such as a dynamoelectric machine. A cylindrical shielding member is provided for protecting the superconducting winding from the influence of the magnetic flux of the stator, and for shielding the heat radiated from the normal-temperature side of the machine, thereby maintaining the superconducting winding at an extremely low temperature. An inner reinforcing body and an outer reinforcing body are fitted to the inner and the outer peripheral surfaces of the cylindrical shielding member so as to reinforce the latter. These reinforcing bodies are effective to reduce the stress in the rotor caused by the centrifugal force and electromagnetic force during a running of the electric rotary machine, thereby protecting the shielding member against breakage and/or deformation.

摘要： In a bending magnet, a core which is substantially sectoral or semi-circular in horizontally sectional configuration and in which opposed magnetic poles are formed and a vacuum chamber for storage of a charged particle beam is disposed in a gap between the opposed magnetic poles, and a pair of upper and lower exciting coils for generating a bending magnetic field in the gap between the magnetic poles of core, the reluctance against the magnetic flux passing through a portion of the core adjacent to the inner circumference of the orbit of the charged particle beam and a portion of the core adjacent to the outer circumference of the charged particle beam orbit is equally uniformed over the overall length of the orbit of the charged particle beam. With this construction, the magnetic flux density becomes uniform in the gap between magnetic poles where the magnetic flux passing through the inner and outer circumference side portions is concentrated and the magnetic flux distribution is uniformed in the orbital direction in the gap, thereby eliminating adverse influence upon the charged particle beam, and the bending magnet can be very effective for use in a synchrotron or a storage ring.

摘要： A superconducting magnet abnormality detection and protection apparatus is for early and surely detecting abnormality in superconducting coils mounted on a vehicle and protecting the superconducting coils. Magnetic flux detecting devices are mounted inside an outer vessel, which is a vacuum container of a superconducting magnet, so as to be opposite to the superconducting coil. Voltages induced in the magnetic flux detecting devices are detected. Voltage signals are led to a decision device. By monitoring the change of the voltage signals with time in a comparing judgment device, it is determined whether there is an abnormality. If there is an abnormality, an alarm indicator informs of an abnormal state, and a protection device takes protection measures such as interruption of the current of the superconducting magnet. Owing to such configuration, heat does not penetrate from the outside into the superconducting coil via instrumentation lead wires of the magnetic flux detecting devices. Magnitudes of vibration and displacement of the superconducting coil can be detected without contacting the superconducting coil. By always monitoring these signals, it becomes possible to early detect an abnormality in the superconducting coil and protect it.
