专利汇可以提供Elastic surface wave device专利检索,专利查询,专利分析的服务。并且PURPOSE:To prevent not only the concentration of electric charge caused by the pyroelectric effect but the discharge on the end face of an elastic surface wave element, by rounding the corner part where the surface and the side face of said wave element adjoin with each other and the corner part where the side faces adjoin with each other. CONSTITUTION:The elastic surface wave element 17 is adhered to the bottom plate 16a via the adhesive 21 when the element 17 is stored into the metallic case 16. Then the corner part where the surface and the side face of the element 17 adjoin with each other is rounded 22, and at the same time the corner part where the side faces adjoin with each other is also rounded 23. For such elastic surface element, the electric charge caused on the element surface by the pyroelectric effect is prevented from concentrating in the corner part. At the same time, the discharge given to the plate 16a of the case 16 from the element surface can be avoided.,下面是Elastic surface wave device专利的具体信息内容。
