△ｔの間浮上した状態のまま一定量前進する。For example, as shown in FIG. 4, each normally conducting coil 25 directly under the oxide high temperature conductor 2 generates a magnetic field by controlling the opening and closing of the relay switch 27 by the control unit 28, and each magnetic body is also excited by this. Then, the oxide high temperature superconductor 2 and the floating body 21 to which it is attached float to a predetermined height from the orbit 1 due to the repulsive force caused by the pinning force. Then, at this time, that is, at a certain time t1, the control unit 28 controls the relay switch 27, and for example, power is supplied to the normal conducting coil corresponding to the magnetic body 20h, and at the same time, the control unit 28 controls the relay switch 27 to supply power to the normal conductive coil corresponding to the magnetic body 20h, and also corresponds to the magnetic body 201 next to it which is in the OFF state. Assume that power supply to the normally conducting coil starts. Then, the magnetic body 201 is magnetized and a magnetic field is formed, and the magnetic body 20c is demagnetized and the generated magnetic field disappears. Therefore, in order to compensate for this change in the magnetic field, a magnetic pole S is provided at a portion of the oxide high-temperature superconductor 2 that is close to the magnetic material 20i, and a magnetic material 20i is
Magnetic poles N are generated at the portions close to 0h, and the attractive force generated between them and the magnetic body 20i becomes a propulsive force and moves forward to the right. Further, the repulsive force generated between the magnetic body 20h and the magnetic body 20h becomes part of a floating blade that levitates the front part of the floating body 21. In this way, the floating body 2 moves forward by a certain amount while remaining in a floating state for a period of time Δt from time t1.
次に、次位の各リレースイッチに対し制御部２８が同様

するとともに既に着磁していた磁性体２０ｄが消磁され

量右方へ前進する。Next, the control unit 28 performs similar control on each of the next relay switches, and as shown in FIG. 5, the magnetic body 20j is magnetized and the already magnetized magnetic body 20d is demagnetized. As before, the floating body 21 moves forward by a certain amount to the right while floating.
また磁性体２０ｄが消磁すると、２０ｅの間で吸引力が
発生し右方へ動く。以下、同様の動作を繰り返しながら
前進していく。Further, when the magnetic body 20d is demagnetized, an attractive force is generated between the magnetic bodies 20e and they move to the right. From then on, move forward while repeating the same actions.

酸化物高温超電導体２′−２についても同様である。For example, as this propulsion mechanism, as shown in FIG.
, 2'-2 may be provided, and the magnetic bodies in the forward direction portion on the track 20' side may be sequentially magnetized. For example, the magnetic material 20'a~ corresponding to the location of the oxide high temperature superconductor 2'
20'C and 20'g to 20'1 are magnetized in advance to a certain magnetic pole, and when the oxide high temperature superconductor 2' is lowered from above, a pinning force, that is, a repulsive force is generated. However, when it descends from the magnetic body to a certain height, that is, the floating blade floats at a height that is balanced with the gravity of the floating body. At this time, a predetermined magnetic pole, for example a magnetic pole different from the upper surface of the magnetic material, is formed on the lower surface side of the oxide high temperature superconductor 2', but the magnetic attraction of the levitation blade is completely different from that magnetic attraction force. This is due to the pinning force that occurs as a phenomenon unique to oxide high-temperature superconductors, and is used to levitate. In addition, this pinning force is caused by the fact that once a magnet is brought close to magnetize a superconductor, an oxide high-temperature superconductor located a certain distance away from the magnetic material will float to that position without attracting or removing the superconductor. It acts not only as a floating blade, but also as an attractive or repulsive force, for example, when the distance between the magnetic body tries to increase, it tries to attract it, and when it tries to decrease, it tries to repel it. . Therefore, in FIG. 6, if the magnetic bodies 20'd and 20'j are respectively magnetized with specific magnetic poles and the magnetic bodies 20'a and 20'g are demagnetized at the same time, each oxide high temperature superconductor 2' -1° 2'-2
The distance between the front end of the magnetic body and the magnetic body 20' 6
．． Since the distance between the front end of the oxide high temperature superconductor 2'-1 and the magnetic body 20'c increases compared to the state immediately before magnetization of the magnetic body 20'j, an attractive force is generated and the oxide The high temperature superconductor 2'1 moves forward to the right. The same applies to the oxide high temperature superconductor 2'-2.
このようにして、進行させようとする方向の磁性体を順
次着磁させると同時に通過し終わる最後の部分を消磁す
ることにより、浮上体を前進させることができる。In this way, the floating body can be moved forward by sequentially magnetizing the magnetic bodies in the direction in which it is to be advanced and simultaneously demagnetizing the last portion that has passed.

However, the arrangement is not limited to maintaining a constant interval. For example, as shown in Figure 7, oxide high temperature superconductors 2'-1, 2'2, ... are arranged in a linear manner in close contact with each other, and each oxide high temperature superconductor is Magnetize the corresponding parts so that they become different types of magnetic poles, and simultaneously magnetize the magnetic bodies 20'd, 20'g, and 20'j at the boundary on the advancing side so that they become reversely inserted magnetic poles. By controlling the magnetization state,
It is also possible to carry out even more efficient promotion.

でしかも小電力での推進が可能である。As explained above, according to the conveyance device according to the present invention, by using an oxide superconductor whose critical temperature is higher than the boiling point of nitrogen (196°C below zero), nitrogen, which can be said to exist inexhaustibly on the earth, can be transported. A liquefied substance is used as a refrigerant to generate a superconducting phenomenon, and at this time, the oxide high-temperature superconductor produces a unique physical phenomenon called pinning force, which, unlike superconducting coils, does not require any electrical energy (zero power consumption). ) The large superconducting magnetic levitation blades generated by the magnetic levitation blades can be used to levitate the levitated object onto the orbit, so there is no need to generate large magnetic force as with conventional types.
Further, it does not consume a large amount of power and can be provided at low cost. Moreover, if the floating object is propelled by using another force that is characteristic of the pinning effect, that is, the suction force that is generated when the floating object is separated within a certain distance from the pinning position, Propulsion is possible with low noise and low power consumption.
