          Appeal No. 96-2661                                                          
          Application 08/177,975                                                      



                    On page 10 of the brief, Appellants argue that claim              
          17 is written in means-plus-function format as sanctioned by                
          the sixth paragraph of 35 U.S.C. § 112, and in accordance with              
          the decision of In re Donaldson, 16 F.3d 1189, 29 USPQ2d 1845               
          (Fed. Cir. 1994).  Appellants argue that the claimed language               
          must be interpreted in light of the specification.  Appellants              
          point to Figure 12 and argue that the S-shape correction                    
          circuit means provides a curve 97 as shown in Figure 12 as                  
          having a maximum   of linearity error of a substantially                    
          constant value over a range of horizontal deflection frequen-               
          cies of 30 kHz to 60 kHz and that the maximum linearity error               
          of a substantially constant value   is less than 5% over the                
          predetermined range of horizontal deflection frequencies of 30              
          kHz to 60 kHz.                                                              
                    Our reviewing court has stated in Donaldson, 16 F.3d              
          at 1193, 29 USPQ2d at 1848, that the "plain and unambiguous                 


          meaning of paragraph six is that one construing means-plus-                 
          function language in a claim must look to the specification                 
          and interpret that language in light of the corresponding                   

                                          5
