                          Rather than repeat the arguments of Appellants or the                                                                         
                 Examiner, we make reference to the briefs  and the answer for             1                                                            
                 the details thereof.                                                                                                                   
                                                                     OPINION                                                                            
                          After a careful review of the evidence before us, we do                                                                       
                 not agree with the Examiner that claims 2 through 4, 7 and 10                                                                          
                 through 12 are properly rejected under 35 U.S.C. § 103 as                                                                              
                 being unpat-entable over Tsuzuki and Katou.                                                                                            
                          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 express teachings or suggestions found in the                                                                         
                 prior art, or by implications contained in such teachings or                                                                           
                 suggestions.  In re Sernaker, 702 F.2d 989, 995, 217 USPQ 1, 6                                                                         
                 (Fed. Cir. 1983).  "Additionally, when determining                                                                                     
                 obviousness, the claimed invention should be considered as a                                                                           


                          1Appellants filed an appeal brief on December 28, 1994.                                                                       
                 We will refer to this appeal brief as simply the brief.                                                                                
                 Appellants filed a reply appeal brief on July 10, 1995.  We                                                                            
                 will refer to this reply appeal brief as the reply brief.  The                                                                         
                 Examiner stated in the Examiner’s letter dated August 4, 1995                                                                          
                 that the reply brief has been entered and considered but no                                                                            
                 further response by the Examiner is deemed necessary.
