          Appeal No. 96-0311                                                          
          Application No. 08/155,771                                                  

          understand, from the instant disclosure and the explanation of              
          counsel at the hearing of January 13, 1999, that this term is               
          applied to describe deformities on the disk, as in portions                 
          either raised or lowered with respect to an ideal flat, smooth              
          surface, between inner and outer peripheries of the disk, thus              
          excluding the peripheral edges of the disk from being                       
          described as “bent.”  Further, a “reference length” is                      
          defined, at page 6 of the specification, as the “linear line                
          AB” wherein the linear line AB is shown in Figure 1 as the                  
          shortest distance between two points A and B on a curve 1                   
          representing a “bent portion” of the disk.  The greatest value              
          of deflection of the curved line is called the “maximum                     
          deflection” and this is shown as “2" in Figure 1.  Although                 
          not described as such in the disclosure, counsel identified                 
          reference length AB as a “chord.”  Thus, if a “chord,” or                   
          line, is drawn from any point on the curve of a deformation on              
          the surface of the disk to any other point on the deformity                 
          curve, that “chord,” or line, is what is referred to as the                 
          “reference length” and the “greatest value of the deflection”               
          is the length of a line drawn perpendicular from the reference              
          length to the maximum point on the curve of the deformity.  As              

                                          6
