Patent JP-S6367709-A (JP)
Title: Superconducting magnet device with emergency demagnetizing device
Inventor: TAKECHI MORIAKI
IPC: H01F6/00
Filed: 1986-09-09
Abstract: PURPOSE:To demagnetize a superconducting magnet in a short time when it is operated in a permanent current mode by providing an emergency demagnetizing unit having a heater circuit and a heater circuit opening/closing switch connected in series with the circuit. CONSTITUTION:A superconducting coil heater 7 is heated by energizing it by a heater power source 8 by closing a heater circuit opening/closing switch 9 to heat a superconducting coil 1. When it exceeds a predetermined critical temperature due to the temperature rise, at least part of the coil 1 is transferred to a normal conducting state to generate a resistance. Even if the small part of the coil 1 is transferred to the normal conducting state, Joule loss occurs due to the resistance of this part to increase the normal conducting transferring part. Thus, an exciting current Ic circulated in a closed circuit having the coil 1 and a permanent current switch superconductor 3 is abruptly attenuated to demagnetize the coil 1.

Abstract: PURPOSE:To make a rack guide consisting of a low rigid material like resins usable whereby hold down a noise to the smallest possible extent as well as to secure lightweight, inexpensive device, by installing a rack bar contact part in and around a rack guide hole. CONSTITUTION:In the case where large turning force is transmitted to an interspace between a rack tooth 6 and a pinion 3, there produces such breakaway force as pushing away a rack bar 5 from the pinion 3 due to a pressure angle of the pinion 3. When this breakaway force is small or rather medium, displacement (t) in the rack bar 5 comes to a range of t1<t<t2 like this. And, this displacement (t) is absorbed as elastic compression deformation t-t1 in a rack guide 7 after the flection t1 of a compression spring 9 and the rack guide 7 come into contact with a set bolt 8.
