METHOD OF MANUFACTURING AN ENERGY TRAPPED TYPE CERAMIC FILTER

摘要

Method of manufacturing an energy trapped type ceramic filter. The method comprises forming a thin layer of thermofusing material on and about the resonator electrode portions. Thereafter an insulative resinous outer layer is placed on the thermofusing material to cover all the portions. A gap or gaps between said resonator electrode and said outer layer is formed by heating the assembly for causing the thin layer to be fused and to be absorbed into said outer layer.
