          Appeal No. 1998-0126                                                        
          Application 08/272,700                                                      


          (filed Mar.  3,                                                             
          1992)                                                                       
                    Claims 1, 4 through 11 and 14 through 24 stand                    
          rejected under 35 U.S.C. § 103 as being unpatentable over                   
          Compton in view of Myochin and Woell.                                       
                    Rather than reiterate the arguments of Appellants                 
          and the Examiner, reference is made to the brief and answer                 
          for the respective details thereof.                                         




                                       OPINION                                        
                    After a careful review of the evidence before us, we              
          will not sustain the rejection of claims 1, 4 through 11 and                
          14 through 24 under 35 U.S.C. § 103.                                        
                    The Examiner has failed to set forth a prima facie                
          case.  It is the burden of the Examiner to establish why one                
          having ordinary skill in the art would have been led to the                 
          claimed invention by the reasonable teachings or suggestions                
          found in the prior art, or by a reasonable inference to the                 
          artisan contained in such teachings or suggestions.  In re                  


                                          4-4-
