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 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
