い。In other words, the contact point (A) remains ON for a certain period of time after the liner (1) approaches the acceleration/deceleration coil (2) and the position detector (4) turns ON, and only during that time, the acceleration/deceleration coil (2) receives an emergency DC current. The current is (+) → (P, ) → (A) → (B3)
You can cross via route 2) → (B4) → (-). As a result, the acceleration/deceleration coil (2) becomes an electromagnet only while energized,
It is possible to attract the liner (1) by visiting a specialist and apply a restraint MJ to stop the liner (1) at the acceleration/deceleration coil (2) position. At this time, since the current flows through the acceleration/deceleration coil (2) for a short fixed period of time, there is no risk of the acceleration/deceleration coil (2) being burnt out due to long-term energization.

′) is also used as an emergency stop coil, even if the liner (1) cannot be stopped with only the acceleration/deceleration coil (2), (2
)→(2'), the liner (1) can be reliably brought to a complete stop. In addition, although the above embodiment describes an emergency stop during a power outage, by replacing the conditions of the power purchase detection relay (121), the liner (1) can also be used in an emergency other than a power outage such as a failure of the control circuit συ.
All emergency stops can be made.
