          Application No. 08/541,894                                                  

          clause of claim 24.  We have reviewed the specification and                 
          note that the specification does not specifically define                    
          “tension.”  Tension is defined in the dictionary as the state               
          of being stretched.  Webster’s II New Riverside University                  
          Dictionary, The Riverside University Publishing Company                     
          (1984).  The specification states that the blade shoulders 68               
          and 69 of the blade are forced against ears 45 and 46 and that              
          the blade is urged inwardly because the engaging member 56 is               
          forced against the back of hole 66 (See specification at page               
          6).  This engagement of the blade would result in stretching                
          or tension on the blade.                                                    
                    In regard to the examiner’s finding of inherency, it              
          is well settled that the burden of establishing a prima facie               
          case of anticipation resides with the Patent and Trademark                  
          Office.  See In re Piasecki, 745 F.2d 1468, 1472, 223 USPQ                  
          785, 788 (Fed. Cir. 1984).  When relying upon the theory of                 
          inherency, the examiner must provide a basis in fact and/or                 
          technical reasoning to reasonably support the determination                 
          that the allegedly inherent characteristic necessarily flows                
          from the teachings of the applied prior art.  See Continental               
          Can Co. v. Monsanto Co., 948 F.2d 1264, 1268, 20 USPQ2d 1746,
