          Appeal No. 1998-1659                                                        
          Application No. 08/486,635                                                  


          that the lateral cross-sectional area for the second aperture               
          should be less than or equal to about 55 percent of the                     
          lateral cross-sectional area of the first aperture.  Since a                
          range of less than or equal to about 55 percent overlaps the                
          claimed range of less than 50 percent, the teachings of Lee                 
          render the claimed range obvious.  See In re Malagari, 499                  
          F.2d 1297, 1302, 182 USPQ 549, 553 (CCPA 1974).  Therefore,                 
          our affirmation of the rejection of claim 8 over Buckley in                 
          view of Lee and Ovshinsky is proper.                                        
               Accordingly, appellant's request has been granted to the               
          extent that our decision has been reconsidered, but such                    
          request is denied with respect to making any modifications to               
          the decision.                                                               
               No time period for taking any subsequent action in                     
          connection with this appeal may be extended under 37 CFR                    
          § 1.136(a).                                                                 
                                      REHEARING                                       
                                       DENIED                                         






                                          5
