    • PURPOSE:To obtain a ceramic oscillator of flexural oscillation mode which has reduced capacity by utilizing a coefficient k15 of a shear mode with a large coefficient of electromechanical coupling and constituting a sandwich structure which uses metallic plates. CONSTITUTION:When an AC electric field is impressed between the metallic plates 11 and 11', directions A and A' of polarization are perpendicular to the AC electric field and shear forces (p) and (p'), and (q) and (q') are generated at piezoelectric magnetic plates 10 and 10'. The primary oscillation of the ceramic oscillator is excited by shear forces (r) and (r'), and (s) and (s') as reaction to the generation of said forces. The forces (s') and (r') generated at the center part and the forces (s) and (r) generated at end parts are mutually opposite in direction, so only even-order modes are excited to reduce spuriousness. Further, a large coefficient k15 of coupling is utilized, so the capacity ratio gamma is reduced. This oscillator is used to realize a filter which has wide passing-band width in a low frequency range.
    • 目的:通过利用具有大的机电耦合系数的剪切模式的系数k15并且构成使用金属板的夹层结构来获得具有减小容量的弯曲振荡模式的陶瓷振荡器。 构成:当在金属板11和11'之间施加交流电场时,偏振方向A和A'垂直于交流电场,剪切力(p)和(p')和(q)和(q)和 q')在压电磁性板10和10'处产生。 陶瓷振荡器的主要振荡由剪切力(r)和(r')和(s)和(s')作为对所述力的产生的反应而激发。 在中心部分产生的力(s')和(r')和端部产生的力(r)在方向上相互相反,所以只有偶次模式被激发以减少假性。 此外,利用耦合的大系数k15,因此容量比γ降低。 该振荡器用于实现在低频范围内具有宽通带宽度的滤波器。

    • PURPOSE:To prevent the mechanical and thermal distortion of a holder from giving effect on a piezoelectric substrate, by providing a recess to the holder, inserting a connecting end of the piezoelectric substrate to the recess so as to fix both parts. CONSTITUTION:Leads 3 of an input/output transducer 1 formed on the piezoelectric substrate 2 are arranged together at one end.

CONSTITUTION:An electrode 5 is vapor-deposited to a crystal substrate 4 which is polished up to a prescribed thickness, and then plural thin grooves 6 of orthogonal grating shapes are provided on the substrate 4. Thus the substrate 4 contains rectangular crystal bars arrayed in plural columns and rows.

    • PURPOSE:To perform operation at frequencies from sevrtsl hundreds KHz to several MHz, to facilitate manufacture, and to improve reliability, by providing a piezoelectric ceramic plate whose lengthwise center part width is less than those of both ends, and electrodes and terminals separated by separation zones. CONSTITUTION:This oscillator consists of a piezoelectric ceramic plate 10 which is polarized in the thickness direction on the whole and has a narrow-width part where the lengthwise center part has width W' is less than the width W of both end parts, electrodes 11a-11d obtained by separaing thin metallic films formed both side surfaces of the ceramic plate 10 by separation zones 13a and 13b at different lengthwise positions while the narrow-width part is sandwiched, and terminals 12a and 12b where the electrodes 11a and 11c, and 11b and 11d opposed at both the lengthwise end parts are connected mutually. When an AC voltage is applied those terminals 12a and 12b, an AC electric field is applied to the narrow-width part to cause longitudinal oscillation in the widthwise direction, and even if this longitudinal oscillation propagates to both the end parts, it is atteanuated, thereby holding the end parts tightly. The resonance frequency depends upon the width W' of the narrow-width part and even oscillators for several hundreds KkHz- several MHz band are of size which is manufactured easily.

    • PURPOSE:To ensure a reduction of the input impedance over a wide band, by connecting the elastic plate to the two piezoelectric porcelain plates in the longer direction and then securing such arrangement in that the residual polarizing directions of these two porcelain plates may be opposite to each other. CONSTITUTION:The elastic plates 6 and 7 made of the constant elastic material are connected to the thickness slip mode piezoelectric porcelain plates 8-0 and 8-1 each in the longer direction to form a flexed vibration converter. Then the plates 8-0 and 8-1 are arraged so that the residual polarizing directions of these plates may be opposite to each other and also vertical to the longer direction. In such constitution, the alternating electric signal is applied betwen the support lines 9/10 and the lead wire 11. As a result, the plates 8-0 and 8-1 receive the shearing stress as shown by the arrows A-D to produce a flexion as shown by the dotted lines in the figure. In this case, the plates 8-0 and 8-1 are inserted in parallel to each other in terms of electricity to secure the parallel exitence of the buffer capacity. Thus the input/ output impedance can be reduced. On the other hand, the equivalent capacitance is also increased to maintain the wide-band characteristics.

    • PURPOSE:To obtain a winding oscillation converter which can eliminate the additional LC electric circuit by functioning as the low capacity ratio converter, by distributing the elastic plate and the piezoelectric ceramic plate connected virtically in the longer direction and setting the piezoelectric ceramic plate so that its polarization direction may be virtually vertical to the longer direction of the elastic plate. CONSTITUTION:Piezoelectric ceramic plate 21 which is polarized in the direction of arrow mark 23 is provided between the longer directions of elastic plates 19 and 20 made of the everlasting elastic material in such way that polarization direction 22 may be virtually vertical to the longer directions of plates 19 and 20. And the single- side end faces of plates 19 and 20 opposing to the both electrode faces of plate 21 are connected vertically via the adhesive such as the solder or the like into the tuning-bar shape. Support wires 26 and 27 attached to the node of the winding oscillation double the function of the lead wire. Furthermore, if the AC voltage of the fixed frequency is applied to wires 26 and 27, plate 21 features the thickness shear vibrations in the direction of arrows 23 and 24. By this vibration, the converter has the winding oscillation shown by the dotted line 25.
