          Appeal No. 1996-1456                                                        
          Application No. 08/059,840                                                  

               Independent claim 15 lacks the 10% to 30% by weight filler             
          limitation set forth in claims 1, 21 and 26, but does require (1)           
          a plurality of projection members extending from one surface of             
          each casing member which are respectively aligned when the casing           
          members are contacted together for welding and (2) means indented           
          on the other surface of at least one casing member to receive a             
          welding horn for transmission of an application of ultrasonic               
          energy to the contacted surfaces of the projection members.                 
          Implicitly acknowledging the lack in Hitachi Maxell and Kato of             
          any teaching or suggestion of a recording medium cartridge having           
          these features, the examiner turns to Kita and Young.                       
               Kita discloses a tape cassette case composed of upper and              
          lower half cases formed of, for example, ABS resin.  The half               
          cases include complementary projections (see Figures 6 through              
          24) which are adapted to be abutted and ultrasonically welded               
          together by energy supplied from a welding horn 80 applied                  
          against the rear surface of one of the half cases (see Figures 10           
          through 24).  The welding projections are particularly configured           
          to avoid problems caused by excess melted resin and resin                   
          particles generated during the welding operation (see column 4,             
          line 59 et seq.).                                                           
               Young discloses a tape cassette having upper and lower                 
          casing half members which can be assembled without the use of               
          screws.  To this end, the lower half member includes at each                

                                          8
