          Appeal No. 1999-2029                                       Page 3           
          Application No. 08/431,360                                                  


               Rather than reiterate the conflicting viewpoints advanced              
          by the examiner and the appellants regarding the above-noted                
          rejections, we make reference to the answer (Paper No. 11,                  
          mailed October 24, 1997) for the examiner's complete reasoning              
          in support of the rejections, and to the brief (Paper No. 10,               
          filed October 6, 1997) and reply brief (Paper No. 12, filed                 
          December 29, 1997) for the appellants' arguments thereagainst.              


                                       OPINION                                        
               In reaching our decision in this appeal, we have given                 
          careful consideration to the appellants' specification and                  
          claims, to the applied prior art references, and to the                     
          respective positions articulated by the appellants and the                  
          examiner.  As a consequence of our review, we make the                      
          determinations which follow.                                                


               In rejecting claims under 35 U.S.C. § 103, the examiner                
          bears the initial burden of presenting a case of obviousness.               
          See In re Rijckaert, 9 F.3d 1531, 1532, 28 USPQ2d 1955, 1956                
          (Fed. Cir. 1993).  A case of obviousness is established by                  
          presenting evidence that the reference teachings would appear
