In this paper, the theoretical and experimental study on the electro-mechanical filters of λ/4 - coupler type is described First, the equivalent circuits of these kinds of mechanical filters are discussed. The two design methods of the filters are given and the experimental investigations on the methods are shown. Next, on the basis of the above fundamental consideration, the authors develop the synthesis of the filters by an exact-design method.　The type of the electro-mechanical filters used in this experiments are electro-strictive and longitudinal-vibration coupler one.　In the last chapter, the authors, from the point of practical use, investigated the miscellaneous type of the fi1ters; one of them is constructed of a disc resonator of radial-vibration, and the other is of a disc resonator of transversal-vibration.　The special features of the investigation in this paper are as follows: 1) the application of the notion of imaginary gyrator to λ/4-coupler mechanical filters and the analysis by equivalent circuit, 2) the synthesis of the electro-mechanical filters by an exact-design method, 3) the investigation of some new types of mechanical filter for practical use.
