          Appeal No. 1997-0384                                                        
          Application 08/086,498                                                      


          predetermined distance from the first end toward the second                 
          end during blank intervals, the display signal generator                    
          generating display signals which [do not] control the display               
          element to not display an information image during the blank                
          interval, the blank interval being proportional to the decay                
          rate of the display screen such that each information image                 
          fades substantially from the display area before the                        
          information image is moved to reduce interference between                   
          information image frames; and                                               
               a liquid crystal display device controller coupled to the              
          display signal generator to receive the display signal                      
          generated by the display signal generator and to generate                   
          control signals to power at least selected portions of the                  
          liquid crystal display element responsive to the display                    
          signal.                                                                     
               The following references are relied on by the examiner:                
          Hilsum et al. (Hilsum)        3,972,040                Jul. 27,             
          1976                                                                        
          Tsunoda                       4,646,081                Feb. 24,             
          1987                                                                        
               Claims 1, 2, 6 to 12, and 15 were rejected under 35                    
          U.S.C.   112, second paragraph, as being indefinite (see                   
          final rejection, page 2).  This rejection was not repeated in               
          the Answer, and accordingly this rejection is taken by us as                
          having been withdrawn.  See MPEP  1208.                                    
               Claims 1, 6 to 9, 11, 12, 15, 18, 20, and 21 stand                     
          rejected under 35 U.S.C.  103.  As evidence of obviousness,                
          the examiner relies upon Tsunoda in view of Hilsum.                         
               Rather than repeat the positions of appellants and the                 
                                          4
