Abstract

PURPOSE:To reduce occurrence of the harmful spurious by securing the vibrating force at the center of the belly lines at two areas each via the tuning bar and thus preventing the functioning of the useless coupled vibrating force. CONSTITUTION:For resonators 3', 6' and 9' which connect additional couplers 18' and 19', the 2nd-style flexion lateral vibration tuning bar is used. Among center points 25, 26, 27, 28, 27', 29' and 30 of the vibration belly lines of the two areas of resonators 3', 6' and 9', main couplers 11, 13, 14 and 16 are given the butt welding to each other. And then the butt welding is given to additional couplers 18' and 19' at center points 26, 28, 28' and 30 each.
