          Appeal No. 1998-0695                                                        
          Application 08/400,320                                                      


          Appellant makes only a single argument to rebut the                         
          examiner’s rejection of claim 1.  Specifically, appellant                   
          argues that the collective teachings of Crapo, Elsasser and                 
          Tanaka do not teach or suggest the claim recitation that “a                 
          labyrinth seal is formed between said flange portion of said                
          shaft/hub assembly and said outer race of said upper ball                   
          bearing assembly and said inner surface of said bearing                     
          sleeve” [brief, page 5].  Although the examiner asserts that                
          Elsasser teaches the claimed labyrinth seal, appellant argues               
          that Elsasser does not support the examiner’s findings [id.,                
          pages 6-7].                                                                 
          After a careful consideration of the respective                             
          positions asserted by appellant and the examiner, we find                   
          ourselves in agreement with appellant.  Although all the                    
          individual elements of a disc drive are taught by the                       
          references, including a labyrinth seal, we agree with                       
          appellant that the labyrinth seal of Elsasser is not formed by              
          the specific components recited in claim 1.  The examiner                   
          seems to view the seal of Elsasser as equivalent to the                     
          claimed seal.  Although the Elsasser seal and the claimed seal              
          may achieve the same function of protecting the delicate                    
                                         -7-
