                                  DECISION ON APPEAL                                  
               This is a decision on appeal under 35 U.S.C. § 134 from                
          the  rejection of claims 4, 5, 12, and 13.  We reverse.

               The invention at issue in this appeal relates to static                
          random access memories (SRAMs).  An increase in the size and                
          storage capacity of SRAMs has made it difficult to generate                 
          and distribute short duration clock pulses on a large scale                 
          for large, high-speed SRAMs.  Although such clock pulses
