摘要： Disclosed is a method of preparing a micro-structured powder for bonded magnets having high coercivity, which is advantageous in terms of low preparation costs by recycling magnet scraps, simplified mass production, minimal environmental contamination by such a recycling process, and the preparation of stable anisotropic powders having high coercivity. Further, a magnet powder prepared by the above method is provided. The current method is characterized in that R—Fe—B type anisotropic sintered magnets or scraps thereof are crushed to prepare 50–500 μm sized magnet powders, which are then mixed with 1–10 wt % of rare earth fluoride (RF3) powders and thermally treated at high temperatures (500–1100° C.) in a vacuum or an inert gas, to cause the change of matrix-near surface and grain boundary of the powders. Thus obtained powders include a matrix phase having R2Fe14B crystal structure, a R-rich grain boundary phase containing rare earth fluoride, and other phases, in which the matrix phase has an average grain size of 1–20 μm, and the powders have an average size of 50–500 μm with superior magnetic characteristics of (BH)max≧20 MGOe and iHc≧5 kOe.

摘要： A high voltage gate driver circuit according to an embodiment of the present invention controls an operational range of an output signal of a level shifter to be appropriate for an operational range of a reshaper through a VIV converter. Even though the voltage range of the signal which is input from the high voltage gate driver circuit to the level shifter is different from the operational range of the reshaper, the input signal can always be recognized exactly regardless of the VTH voltage of the reshaper by controlling the operational range of the signal through the VIV converter. In addition, incorrect operation of the circuit can be prevented by erasing a common mode noise which is input with the input signal.
