          Appeal No. 1998-2590                                                        
          Application No. 08/255,083                                                  


               Looking first at the examiner’s rejection of claims 1                  
          through 4 and 8 through 11 under 35 U.S.C. § 103(a) based on                
          the collective teachings of Yamamoto, Powers and Shealy, we                 
          note that Yamamoto discloses a method of manufacturing an                   
          insulated electric power cable that includes a cured                        
          insulation material (3) applied over a conductor (1, 2) and a               
          layer of plastic compound (5) comprising a thermoplastic resin              
          and 5-70 parts by weight of calcium oxide as a moisture-                    
          absorbing agent overlying the insulating material.  In column               
          2, lines 30-41, it is indicated that                                        
                                                                                     
                    [t]he presence of calcium oxide in the layer of                   
                    plastic compound provided on electric conductors in               
                    accordance with this invention serves to give an                  
          insulation     layer of polyethylene which is free of                       
          microvoids.  The    formation of micro-voids within the                     
          insulation layer is      usually attributable to the invasion               
          of steam during the      curing process, using saturated steam              
          as the heating medium.        But when the calcium oxide-                   
          containing layer is provided over       the insulation layer or             
          between the conductor and the           insulation layer, any               
          invading steam can be caught or         absorbed by the calcium             
          oxide, serving in this case as the      moisture-absorbing                  
          agent.                                                                      
                                                                                     
               As is argued by appellant (brief, page 7), Yamamoto has                
          absolutely nothing to do with aeolian and galloping vibrations              

                                          6
