                                                                 OPINION                                                                      
                         In reaching our decision on the issues raised in this                                                                
                appeal, we have carefully assessed the claims, the prior art                                                                  
                applied against the claims, and the respective views of the                                                                   
                examiner and the appellant as set forth in the Answer and the                                                                 
                Briefs.  As a result of our review, we have determined that the                                                               
                rejection should be sustained.  Our reasoning in support of this                                                              
                conclusion follows.                                                                                                           
                         In the case of a Section 103 rejection, the examiner bears                                                           
                the initial burden of presenting a prima facie case of
