Piezoelectric ceramic resonator
专利汇可以提供Piezoelectric ceramic resonator专利检索，专利查询，专利分析的服务。并且A piezoelectric ceramic resonator vibrating resonantly in a thickness-shear vibration mode, which is free from unwanted vibrations in a high frequency range. The piezoelectric ceramic resonator comprises a thin wafer of piezoelectric ceramic material polarized in a direction parallel to the major surfaces thereof. A tetragonal electrode is applied to a part of one of the major surfaces, and a counter electrode is applied to another of the major surfaces, the counter electrode being at least as large as the area of the tetragonal electrode. Two slots are positioned along the opposite edges of the tetragonal electrode. The two slots have walls which are perpendicular to the major surfaces and the slots are at least as long as the opposite sides of the tetragonal electrode. At least one of the two slots has the ends closed by being spaced inwardly from the edges of the wafer.，下面是Piezoelectric ceramic resonator专利的具体信息内容。
