          Appeal No. 1997-3967                                                        
          Application No. 08/482,058                                                  


          from a canceled claim, 22, and it is unclear whether “contact”              
          on line 2 of claim 27 refers to “contact hole.”                             
               For their part, at page 4 of the brief, appellants                     
          acquiesce in the rejection under 35 U.S.C. § 112, second                    
          paragraph.  Accordingly, we will, pro forma, sustain the                    
          rejection of claims 25 through 27 under 35 U.S.C. § 112,                    
          second paragraph.                                                           
               We now turn to the rejections based on 35 U.S.C. § 103.                
               With regard to the rejection of claims 14, 16, 19, 21,                 
          23, 26 and 28 over Denda, we will sustain this rejection for                
          the reasons set forth by the examiner at page 4, and then                   
          again, at pages 5-6 in the response to arguments section.  We               
          also elaborate on the examiner’s reasoning as follows.                      
               Appellants contend that Denda does not disclose nor                    
          suggest the claimed “filaments.”  They suggest that film 16                 
          and dielectric 9 can form no “filaments” because film 16 of                 
          Denda is not adjacent the outer edges of the emitter electrode              
          and the base dielectric layer.  Appellants also contend that                
          because film 16 of Denda is continuous, it is not in the form               
          of a filament.  We disagree.  The claims of interest do not                 
          specify the thickness of the claimed “filaments” nor do they                
                                          5
