          Appeal No. 98-1604                                                          
          Application 08/354,539                                                      


                                       OPINION                                        
               We have carefully reviewed the appellant's invention as                
          described in the specification, the appealed claims, the prior              
          art applied by the examiner and the respective positions advanced           
          by the appellant in the brief and by the examiner in the answer.            
          As a consequence of this review, we will not sustain any of the             
          above-noted rejections.                                                     
               Considering first the provisional rejection of claims 16,              
          18, 20-24, 27-32 and 34-40 under "the judicially created doctrine           
          of double patenting" over claims 1-21 of the appellant's                    
          copending application Serial No. 08/197,610, the appeal of claims           
          1-21 in that application has been dismissed.  This being the                
          case, the question of double patenting is moot and, accordingly,            
          this rejection cannot be sustained.                                         
               We now turn to the rejections under 35 U.S.C. § 103 of                 
          claims 16, 18-25 and 27-40 as being unpatentable over Yamada in             
          view of Ascari and claim 26 as being unpatentable over Yamada in            
          view of Ascari and Japanese abstract.  We initially note that in            
          rejecting claims under 35 U.S.C. § 103, the examiner bears the              
          initial burden of presenting a prima facie case of obviousness.             
          In re Rijckaert, 9 F.3d 1531, 1532, 28 USPQ2d 1955, 1956 (Fed.              
          Cir. 1993); In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443,             

                                          4
