Abstract: A process for producing a starting powder material for use in the fabrication of high performance R-Fe-B permanent magnets comprising a specified R₂Fe₁₄B compound as the principal phase, which is characterized by adding to the said principal phase compound 70 % by weight or less of a specified alloy powder comprising an R₂Fe₁₇ compound. This process enables production of a starting alloy powder material with considerably reduced contents of the unfavorable B-rich and R-rich phases which impair the magnetic properties of the final magnet, because the starting powder blend allows the B-rich and R-rich compounds in the principal phase alloy powder to react with the R₂Fe₁₇B compound.

Abstract: A multinode, multicast communications network has a distributed control for the creation, administration and operational mode selection operative in each of the nodes of the network. Each node is provided with a Set Manager for controlling either creation of, administration or access to a set of users to whom a multicast is to be directed. The Set Manager maintains a record of the local membership of all users associated with the node in which the Set Manager resides. A given Set Manager for each designated set of users is assigned the task of being the Set Leader to maintain membership information about the entire set of users in the multicast group. One of the Set Managers in the communications network is designated to be the Registrar which maintains a list of all the Set Leaders in the network. The Registrar insures that there is one and only one Set Leader for each set of users, answers inquiries about the membership of the sets and directs inquiries to appropriate Set Leaders if necessary. All of the set creation, administration and control functions can therefore be carried out by any node of the system and provision is made to assume the function at a new node when failure or partition in the network occurs.

The gate recess (110) has the asymmetrical two-stage recess structure having a second bottom surface (112a) only at the source side part of the side wall of the recess (110), wherein the second bottom surface (112a) is positioned at a depth between a first bottom surface (111 a) in contact with the gate electrode (10) and the upper surface of the semiconductor layer (2) and is not in contact with the gate electrode (10). Therefore, the thickness (Da2) of the active layer at the source side part is larger that that (Da1) in the one-stage recess structure, with a result that the source resistance is reduced because of an increase in the thickness (Da2) of the active layer at the source side region while avoiding deterioration of the gate drain breakdown voltage due to an increase in the thickness of the active layer at the drain side region.
