摘要： PURPOSE:To simplify the constitution of a ceramic filter, by forming the filter with a piezoelectric ceramic plate in which narrow width part having the width of the lengthwise center part set smaller than the widths of both ends is polarized in the direction of thickness. CONSTITUTION:When an AC electric field is applied between terminals 6 and 8 of a ceramic oscillator, the electric field is applied to a stepped part via electrodes 2'-1 and 2-1 and then to the center stepped part to which a polarizing process is applied. As a result, the vertical oscillations of width direction are excited at said center stepped part by an effect of the piezoelectricity. No polarizing process is applied to a piezoelectric ceramic plate 4 set between electrodes 2'-1 and 2-1 as well as 2'-2 and 2-2. Therefore the plate 4 functions just as a dielectric matter.

摘要： PURPOSE:To eliminate magnetization and residual strain during welding, and to improve mechanical filter characteristics, by heating an electromechanical transducer, a resonator, and a coupler at specific temperature after electric welding. CONSTITUTION:Copper-made electrodes 5 and 6 are placed on and under electromachanical transducers 1, a coupler 3, and resonators 2 and while the electrodes are depressed, a large current is applied. Then, resistive heat generation is caused at contacting parts of the electrodes 5 and 6 to weld the contacting parts of both the metals. At this time, the transducers 1, coupler 3, and resonators 2 are magnetized because they consist essentially of constantly elastic metals, causing residual magnetization. To reduce this residual magnetization and mechanical residual strain, a heat treatment is performed at sufficient temperatures (100-200 deg.C) and then the temperature is lowered gradually. Consequently, mechanical sharpness and a decrease in Q is prevented.

摘要： PURPOSE:To attain miniaturization by facing ground patterns in the direction of exposing the ground pattern of a corner part opposite to the one whose base is excised, pasting them, connecting and fixing a ground terminal to the ground pattern of the part exposed in the excised part. CONSTITUTION:A first substrate 21 has a zigzag delay line pattern 26 on a surface 25 of a ceramic substrate main body 23 having a form that the right- lower corner part is excised like a circular arc (24 shows the excised part) from the rectangle of a length L3 and a width W3, and has a ground pattern 28 on the almost whole surface of a rear face 27. A second substrate 22 has the same structure as the first substrate 21, the second substrate is turned at 180 deg. and the rear faces 27 and 27a are pasted oppositely. Ground terminals 35 and 35a are connected and fixed to the parts of the ground patterns 28 and 28a. Thus, the connecting and fixing places of the ground terminals can be ensured, the length of the delay line patterns can be lengthened and the miniaturization can be attained.
