Abstract

PURPOSE:To make it possible to set optional characteristics from the exterior by mounting the wave receiving converter in the opposite direction of the wave transmitting converter on the production of the second reflection lattice. CONSTITUTION:The elastic surface wave which has been radiated from the wave transmitting converter on the piezo-electric body is propagated in the reflection lattice 17 consisting of several reflectors. On the other hand, the reflection lattice 19 is mounted in parallel to the lattice 17, the reflector of the lattice 17 and that of the lattice 19 are set in parallel each other, and the wave receiving converter 20 is mounted in the opposite direction of the wave transmitting converter on the production of the lattice 19. Thus optional characteristics can be set from the exterior.
