A fast algorithm for 3D part reconstruction from a 3-view drawing is presented. A set of rules are specified to facilitate the part reconstruction. The main idea is to use the rules to determine the truth or falsity of 3D faces and the coexistence or non-coexistence relationships between 3D faces. In a graph search formulation of the reconstruction problem, these rules can reduce remarkably (a) the graph search space, (b) the occurrence of backtracking in the search and (c) the branching factor of the tree expansion. We shall present our method with illustrations. Currently we limit the type of part to be plane-faced for presentation simplicity, although we are extending our method to cover the cylindrical parts, too. Experimental results indicate the set of rules is useful and our reconstruction method is very effective.

The core loss mechanism of low loss grade Mn-Zn ferrite in the frequency from 1MHz to 10MHz was investigated in order to find out the possibility of developing Mn-Zn ferrites to be used at such high frequency region. under the condition of f;B=25KHz.T, it was found that dielectric loss dominated the core loss at the frequency between 1.1 and 3MHz, while eddy current loss dominated the core loss at the frequency higher than 3MHz. It is suggested that decrease of grain boundary capacitance and increase of grain resistivity of the core mar be the suitable ways for the Mn-Zn ferrites to be used at such frequency region.
