摘要:
The present invention relates to a method for measuring three-dimensional spatial magnetic field distributions used particularly in measuring the magnetic field distribution in a small spatial region such as a leakage magnetic field of a magnetic head and the object thereof is a measuring method capable of measuring a high frequency magnetic field in the small spatial region with a high precision.
摘要:
In a method for cutting ferrous material in accordance with the present invention, a water-soluble cutting fluid containing nanometer-size carbon particles is electrolyzed, and a ferrous workpiece is cut by a diamond cutting tool 9 while supplying the electrolyzed water-soluble cutting fluid onto a cutting point between the diamond cutting tool 9 and the ferrous workpiece.
