摘要： A piezoelectric vibration device using the thickness system vibration used for communication equipment, etc. The device is provided with weight reducing sections (231 and 232) or weight adding sections at parts where an anharmonic overtone mode is relatively strongly excited and which are at least in the vicinity of the outer periphery of an input electrode (21) and an output electrode (22) or a common electrode (23). The total area of the input and output electrodes (21 and 22) is made smaller than the area of the common electrode (23) and the weight reducing or adding sections (231 and 232) are extended to part of the common electrode (23) facing the electrodes (21 and 22). It is preferable to make the thickness of the common electrode (23) formed on one main surface of a quartz plate (1) two to ten times as large as those of the input and output electrodes (21 and 22) formed on the other main surface of the plate (1). The electrodes are made of silver, gold, or a metal composed mainly of gold or silver. Therefore, a piezoelectric vibration device which can suppress the spurious vibration mode generated near the principal vibration and has an excellent and wide-band pass band characteristic and an excellent guaranteed damping amount characteristic on the outside of the pass band is obtained.

摘要： The present invention relates to radioelectronics and can find application in developing signal frequency discriminators. According to the invention, the filter comprises a piezoelectric-crystal plate 1 made of La-Ga silicate, two pairs of overlap exciting electrodes 2, 3 and 4, 5, and leads 6. There were selected experimentally in the proposed filter such a ratio between the length of the electrodes along the axis of acoustical coupling, the area of the electrodes, and the wafer thickness that makes it possible to extend the filter frequency range towards higher frequencies. The proposed filter construction provides for a higher temperature stability of the filter average frequency in a wide range of above-zero temperatures, and a reduced level of side passbands.

摘要： Résonnateur piézoélectrique à piégeage d'énergie (75) possédant un substrat piézoélectrique (78) pourvu d'électrodes (80, 85) disposées sur chacune de ces surfaces principales. Ces électrodes comprennent en outre une pluralité de sous-électrodes interconnectées électriquement et couplées acoustiquement (90, 95, 105, 110). La fréquence de résonnance de ces résonnateurs peut être commandée en faisant varier la séparation et, par conséquent, le couplage acoustique entre les sous-électrodes. Un certain nombre de ces résonnateurs peut être formé sur un seul substrat de manière à travailler sensiblement indépendamment les uns des autres. Le résonnateur peut être conçu de manière à présenter une crête de réponse pointue et peut être utilisé en tant que résonnateur d'oscillateur.

摘要： The Lame mode quartz crystal resonator vibrating in overtone mode is formed of an X-plate quartz crystal obtained in a manner that a blank X-plate quartz crystal having a coordinate of x, y and z axes is rotated through 36.5° to 47° about its y-axis and further rotated through 65° to 85° about a new x'-axis corresponding to the x-axis produced by the rotation about the y-axis and the thus rotated blank X-plate quartz crystal is then cut out along planes parallel to x-y, y-z and z-x planes of the original coordinate system, respectively. The quartz crystal resonator includes a vibrating portion, a supporting frame and a mounting portion formed integratedly. The vibrating portion is connected through two connecting portions to the supporting frame and the mounting portion, as a result of which the quartz crystal resonator has less series resistance R 1 and exhibits minimum vibrational energy losses and minimum frequency change over a wide temperature range.
