摘要： PURPOSE: To obtain a frequency response characteristic the same as that of the 1st order mode even in even/odd number modes by splitting a longitudinal vibrator lengthwise and setting the polarized region in broadwise direction to the opposite polarity so as to eliminate cancellation of generated electric charges of different sign.
CONSTITUTION: A piezoelectric ceramic 11 of the longitudinal vibrator 20 is split in lengthwise direction to form polarized regions 21, 22. The broadwise polarization of the regions 21, 22 is made opposite. Thus, the displacement of the longitudinal vibration mode appears alternately and the deterioration of the frequency response characteristic due to the increase in the number of order in both even/odd number order modes is eliminated.

摘要： PURPOSE:To adjust a converter to be adjusted without touching components except said converter by using a means disconnecting the converter to be adjusted electrically equivalently from other converters while keeping a completed mechanical filter. CONSTITUTION:When a switch 9 is thrown to the position (a), a coil 10 is connected electrically to a damping capacitance Cd2 of a converter V2 at the output side, and also a phase shifter 11 and an amplifier 12 are connected to a converter V1 of the input side and oscillation is produced in the circuit system. The oscillating frequency is compared with a desired frequency of the converter V1 from a reference oscillator 16 at a comparator 15. When the result of comparison is different, a control circuit 14 controls a laser 17 so as to cut the size of the input component being the converter to be adjusted, e.g., the V1. Then the resonance frequency of an output circuit 13 is adjusted. After the adjustment, the switch 9 is thrown to the position (b) and similar adjustoment process is applied to the input converter V2 being the element to be adjusted. Thus, the converter to be adjusted is set to the desired resonance frequency without access to components except said converter.

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 obtain a vibrator of a low capacitance ratio and possible for rugged support by fixing a rectangular metallic plate to the center part of a rectangular piezoelectric ceramic. CONSTITUTION:The metallic plates 2, 2' made of a constant elastic metal are fixed to upper and lower faces of a rectangular piezoelectric ceramic vibrator 1 having a lengthwise residual polarization 3 by an adhesive. In applying an electric field to the metallic plates 2, 2', the vibrator makes a thickness-shear vibration having a vibrating displacement 4. Since the resonance frequency of a composite member where the metallic plates 2, 2' are fixed to the vibrator 1 is lower than the resonance frequency of the vibrator 1 itself, the vibrating energy of the thickness-shear vibration is confined in the composite member. Thus, no vibrating displacement is caused at both ends A, B of the vibrator 1 and both ends are fixed solidly.

摘要： PURPOSE:To suppress a new spurious mode of a mechanical filter by coupling plural oscillators which each consist of a couple of metallic plates joined to the top and reverse surfaces of piezoelectric ceramic. CONSTITUTION:Metallic plates 61 and 61' which are made of constant-elasticity metallic materials and about half as thick as the piezoelectric ceramic 11 are joined to the top and reverse surfaces of the piezoelectric ceramic 11 to constiture an oscillator. Metallic plates 61'a and 61'b of two longitudinal oscillators 60a and 60b having different-length metallic plates 21a and 21b are coupled together by a coupler to constitute the mechanical filter. Thus, while high-order spurious modes are suppressed, the small-sized mechanical filter is manufactured at low cost.
