          Appeal No. 1998-1993                                                        
          Application 08/320,729                                                      


          variables such as operating voltages, device sizes, and the                 
          materials used in the manufacture of the devices.  It is our                
          view that in order for several different references to be                   
          cited as conventional features of a transistor, the                         
          transistors of the several references should all have similar               
          operating ranges, device sizes and device materials.  In other              
          words, a conventional feature of a transistor operating under               
          one condition would not necessarily be a conventional feature               
          of a different transistor operating under different                         
          conditions.                                                                 
          Of particular concern to us is the difference in the                        
          range of voltages in which Morozumi, Asars and Togashi are                  
          designed to operate and the differences in the semiconductor                
          channel materials.  Morozumi describes a liquid crystal device              
          operating at about 10 volts [column 8, lines 26-43; column 11,              
          line 48].  Asars describes a liquid crystal device operating                
          at about 80 volts [column 5, lines 10-12].  Togashi describes               
          a liquid crystal device operating at about 40 volts [page 3,                
          line 113].  Thus, the first thing we note is that the liquid                
          crystal devices of Morozumi, Asars and Togashi are designed to
