Abstract

PURPOSE:To simply improve the guarantead attenuation, by easily adjusting mutual induction between the input and output through the change in the number of lead wires and conductors of short-circuit electrodes. CONSTITUTION:The common terminals 12 and 22 and the external terminals 1 and 3 of transducers are connected between auxiliary electrodes 14 and 24 via short-circuit electrodes 15 and 25 by lead wires 31 and 41. The self-induction of the short-circuit electrodes and the mutual induction with other short-circuit electrodes and the lead wires can be changed by suitably disconnecting a part of the conductor constituting the said short circuit electrodes.
