  • Method of manufacturing heat resisting magnetic scale
    Patent number: 4935070
    Abstract: A method of manufacturing a heat resisting magnetic scale is disclosed which comprises a manufacturing process in which at least a part of a heat resisting base is heated and a manufacturing process in which the part which has been heated is immediately cooled down for the purpose of changing the magnetic characteristics of the part of the base which has been heated and the Curie point of the part which has been heated is raised to 100.degree. C. or higher.A heating resisting magnetic scale which cannot be demagnetized at high temperatures and cannot be separated even if it is subjected to rapid change in temperatures, and which exhibits excellent stability and measuring precision.
