Temp. control using Curie point - uses attraction between permanent magnet and soft magnetic element as temp. falls below Curie point

摘要

The temp. control device uses a mechanical action released by passing through the Curie point. The control comprises a permanent magnet and a piece of -soft magnetic material having the Curie point in the region of a predetermined temp. The mutual attraction between the magnet and the magnetic element is capable of producing relative displacement of the magnet w.r.t. the element, or vice versa to a predetermined position when the temp. falls to the Curie point.
