m components that are used repeatedly. It would be inefficient to model these components several times. Instead, a module can be defined once and used repeatedly. In this way there is only one description to read, and one description to modify when changes are necessary.

Methods to Improve the Physical and Chemical Characteristics of Magnets and Magnetic Materials,ffective for raising the Curie temperature of the alloy, and is further effective for raising the Curie temperature of the alloy, that is, for improving the temperature characteristics of the alloy. Co must be contained in the alloy in an amount within the range of 7–50 at%.

Methods to Prevent Risks During the Production of Magnets and Magnetic Materials,0 and 600υK. The hard-magnetic materials can be obtained in the conventional manner by fusing starting materials suitable for that purpose succeeded by an annealing treatment in a protective gas or in vacuum.

Methods to Improve the Physical and Chemical Characteristics of Magnets and Magnetic Materials, and temperature characteristics are improved without deteriorating the magnetic properties. Ni and Co are added to Nd-Fe-B type alloy by replacing a part of Fe by Ni and Co, and act to form the main phase of the resulting RE-(Fe,Co,Ni)-B alloy. Ni is effective for improving the corrosion resistance

Methods to Lower the Production Costs of Magnets and Magnetic Materials,sired alloy. The impurities would contaminate magnetostrictive rods and interfere with their desired properties. O. McMasters .? has found a method for large scale commercial manufacture of grain-oriented rods. Semi-homogenized buttons, fingers or the like of the rare earth alloy can be charged to a
