          Appeal No. 1997-3089                                       Page 4           
          Application No. 08/577,839                                                  


               We have carefully reviewed, inter alia, the applied                    
          references, as well as the arguments presented by appellants                
          and the examiner.  As a result of such a review we will sustain             
          the rejection of claim 3 under 35 U.S.C.  103 but we will not              
          sustain the rejection of any other claim based on the                       
          references and rationale applied by the examiner.                           
               With regard to independent claim 1, although rather broad              
          in scope, the claim does require a conductive “ring” and it is              
          in that ring in which rotating flux “induces a time-varying                 
          current.”  The examiner applies Persson, which describes a DC               
          motor having many of the characteristics disclosed by the                   
          instant application but, as the examiner admits, Persson does               
          not disclose “a conductive ring for damping (reducing) the                  
          vibration which is caused by the changes of the rotating                    
          magnetic flux” [answer-page 4].  The examiner then relies on                
          “end ring 21" of King and the teaching of Allegre, of                       
          installing a damping winding which includes two conductor                   
          rings, to conclude that it would have been obvious “to include              
          at least one or two conductive rings, as taught by King and                 
          Allegre, in the Persson d.c. motor because this would reduce                
          the unwanted vibration in the motor” [answer-page 4].
