    • First and second refrigerating circuits respectively cause first and second adsorbing bodies to alternately adsorb and release first and second coolants. In the first refrigerating circuit, when the first adsorbing body is heated, it releases the first coolant. The released first coolant is cooled, and discharged through an expansion valve so that a part of the first coolant is liquefied. The resultant latent heat of vaporization can be utilized to cool an object to be cooled. Thereafter, the first coolant is adsorbed when the first adsorbing body is cooled. In the second refrigerating circuit, when the second adsorbing body is heated, it releases the second coolant. The released second coolant is cooled by a liquefied-gas-type cooler, and discharged through an expansion valve so that a part of the second coolant is liquefied. The resultant latent heat of vaporization is utilized to cool the first adsorbing body of the first refrigerating circuit. Thereafter, the second coolant is adsorbed by the second adsorbing body. The liquefied-gas-type cooler cools the second coolant by utilizing the latent heat of vaporization of a liquefied gas. Thus, the amount of the second coolant liquefied after being discharged through the expansion valve in the second refrigerating circuit is increased.
    • 第一和第二制冷回路分别使第一和第二吸附体交替地吸附和释放第一和第二冷却剂。 在第一制冷回路中,当第一吸附体被加热时,其释放第一冷却剂。 释放的第一冷却剂被冷却,并通过膨胀阀排出,使得第一冷却剂的一部分液化。 所产生的蒸发潜热可用于冷却要冷却的物体。 此后,当第一吸附体被冷却时,第一冷却剂被吸附。 在第二制冷回路中,当第二吸附体被加热时,其释放第二冷却剂。 释放的第二冷却剂由液化气体冷却器冷却,并通过膨胀阀排出,使得第二冷却剂的一部分液化。 所得到的蒸发潜热用于冷却第一制冷回路的第一吸附体。 此后,第二冷却剂被第二吸附体吸附。 液化气型冷却器通过利用液化气体的蒸发潜热来冷却第二冷却剂。 因此,通过第二制冷回路中的膨胀阀排出的第二冷却剂液化的量增加。

    • A vehicle has a rotary magnetic field member which is rotatably supported at a position near the surface of a roadway along which the vehicle runs and rotatingly driven by a driving device. The rotary magnetic field member has magnetic poles of different polarities alternately arranged around its circumference. The vehicle also has an electrical power collector for receiving electrical power from an electrical power supply associated with the roadway. The received electrical power is supplied under the control of a controller to the driving device thereby rotatably driving the rotary magnetic field member. The rotary magnetic field member when rotated relative to the roadway made of an electrically conductive non-magnetic material, forms a varying magnetic field in cooperation with the roadway, thereby generating propulsion force for propelling the vehicle and force for suspending the vehicle, so that the vehicle is propelled in a floating state. It is therefore possible to reduce friction between wheels of the vehicle and the roadway and, hence, to suppress wear of the wheels. In a high-speed transportation system of the invention, the electrical power collector picks up electrical power from the electrical power supply and the rotary magnetic field member is rotatingly driven by the power picked up by the electrical power collector.
    • 车辆具有旋转磁场部件,该旋转磁场部件被可旋转地支撑在车辆行驶的道路表面附近的位置,并且由驱动装置旋转驱动。 旋转磁场部件具有围绕其圆周交替布置的具有不同极性的磁极。 车辆还具有用于从与道路相关联的电力供应源接收电力的集电器。 所接收的电力在控制器的控制下被提供给驱动装置,从而可旋转地驱动旋转磁场部件。 当旋转磁场部件相对于由导电非磁性材料制成的道路旋转时,与道路协同地形成变化的磁场,由此产生用于推进车辆的推进力和用于悬挂车辆的力,使得 车辆在浮动状态下被推进。 因此,可以减少车辆的车轮与车道之间的摩擦,从而抑制车轮的磨损。 在本发明的高速运输系统中,电力收集器从电源拾取电力,旋转磁场部件由电力收集器拾取的动力旋转驱动。
