          Appeal No. 2000-1546                                                        
          Application 08/588,149                                                      


          the claims stand or fall together as a single group, we also                
          sustain this rejection with respect to claims 17, 18, 22, 24, 32,           
          36-38 and 40.  Although claims 19-21, 23, 25-31, 33-35, 39 and 41           
          are rejected under 35 U.S.C. § 103 using Imamura with an                    
          additional reference, appellants have made no arguments with                
          respect to the rejections under 35 U.S.C. § 103.  Since we find             
          that the examiner has established a prima facie case of                     
          obviousness, and since appellants have presented no arguments in            
          opposition to this rejection, we also sustain the rejection of              
          claims 19-21, 23, 25-31, 33-35, 39 and 41.                                  
          In summary, we have sustained each of the examiner’s                        
          rejections of the claims on appeal.  Therefore, the decision of             
          the examiner rejecting claims 16-41 is affirmed.
