It takes time to brake the carriage 12, and if the value B is large, a large current is required and overbraking occurs. As a result, the vibration of the carriage 12 can be stopped in a relatively short time.

The distance between the base 31 and the conveyance guide means 32 is detected. Since the magnetic field generated from the damping coil 35 is determined by the current flowing through the damping coil 35, the value corresponding to the magnetic field generated by the damping coil 35 in the control unit 37 is subtracted from the output of the Hall element 36. Thus, the distance between the transport table 31 and the transport guide means 32 is measured.

- Fig. 7 shows the relationship between the output value of the Hall element 41 and the gap. When the gap is changed based on the case where the permanent magnet 42 is in a predetermined position, the output of the Hall element 41 is proportional to the gap. I understand that
- the signal of the Hall element 41 is fed back to the damping coil 25 via the AD converter 43, the differentiation circuit 44, the DA converter 45, and the amplifier circuit 46, and the displacement detected by the Hall element 41 decreases, that is, When the permanent magnet 42 is lowered, a current is passed through the damping coil 25 so that the permanent magnet 42 is raised.
- FIG. 8 shows the measurement of the relationship between displacement and time when a carrying object of a predetermined weight is placed on the permanent magnet 42 so that no current flows through the damping coil 25. It can be seen that the permanent magnet 42 vibrates up and down over a considerably long time.

- the carrier table has a flat plate shape.
- a container plate may be used according to the application.
- positioned in a conveyance guide means and the damping coil are provided separately, these can also be combined. That is, if the damping coil is made of a superconducting material, the device itself can be made more compact.
- the superconductor is cooled by a refrigerator, it is possible to use a refrigerant having a predetermined temperature or lower.
- the non-contact transfer device using superconducting magnetic levitation can transfer an object in a non-contact state, for example, an object or substance in a chamber under different atmosphere and Z or temperature conditions can be transferred to the outside.
- the force can also be moved, and it can be used particularly effectively for moving and transporting semiconductor elements and parts in the chamber, or for transporting samples and bacteria in a sterile room.
- the vibration transmitted to the transfer object is suppressed even if there is vibration from the outside during transfer that is less affected by external vibration. Can be transported while.
- the transfer object placed on the transfer table up and down. Therefore, when combined with the horizontal movement of the transfer table, the transfer object can be moved in three dimensions. It becomes.
- the transfer platform when the transfer platform is attached to the tip of the robot hand and moved back and forth, and left and right, the object to be transferred can be remotely operated while being isolated from the transfer platform. Therefore, for example, when the transfer object has a high potential, the transfer object can be moved in an insulated state from the transfer table in the ground state.
