摘要： PURPOSE:To obtain a miniature multi-mold filter which has a wide band characteristics and can be used in a range of 500kHz-1MHz, by attaching a set of electrodes made of a constant elastic metal with a space decided by the pass band width to the lengthwise counter surfaces of a rectangular piezoelectric ceramics having the residual polarization in the lengthwise direction and utilizing the vertical effect. CONSTITUTION:Constant elastic metallic electrodes (elinvar, etc.) 2, 2' and 2'' are fixed on both sides of a rectangular piezoelectric ceramics 1 having a residual polarization 3 in the lengthwise direction and utilizing the vertical effect by means of an adhesive like solder, etc. An input signal of a pass band frequency is impressed between input side electrodes 5 and 5' of such a filter from an oscillator 4. Thus the vibrations of a thickness slip mode are generated between input side electrodes 2 and 2'', and the vibration energy is enclosed under electrodes by a mass load effect of the electrodes. In the same way, the vibration energy is also enclosed under an area between output side electrodes 2' and 2''. Thus this filter can be used in a wide band of frequencies owing to use of the piezoelectric ceramics having a large electric-mechanical coupling coefficient as a piezoelectric material.

摘要： PURPOSE:To obtain a longitudinal vibration transducer having uniform and stable characteristic by manufacturing lots of longitudinal vibration transducers from a ceramic raw board at the same time in the same process so as to reduce variation of the characteristic of each longitudinal vibration transducer. CONSTITUTION:Electrode films 2, 3 are formed on upper and lower sides of a piezoelectric ceramic board 1 having a size from which plural piezoelectric boards for longitudinal vibration transducer are formed. A high voltage is impressed to the piezoelectric ceramic raw board 1 formed with the electrode films 2, 3 so as to apply polarization in the broadwise direction. A constant elastic metallic plate 4 is bonded to an opposite position clipping the piezoelectric ceramic raw board in the same shape on both the upper and lower faces of the piezoelectric ceramic raw board 1 applied with polarization. The electrode films 2, 3 of the piezoelectric ceramic raw board 1 are cut off and removed at a desired position in response to the electric characteristic of the transducer to be manufactured. The piezoelectric ceramic 1 is cut off and separated into the size of each longitudinal vibrating transducer so as to form the paper-tablet form longitudinal vibration transducer.

摘要： PURPOSE:To obtain a mechanical filter converter which can easily be manufactured and has excellent mechanical/electrical characteristics by cascading by turns elastic plates made of a constant elasticity metal material and piezoelectric ceramic in the length direction of an inflectional vibration converter. CONSTITUTION:Inflectional vibration cinverter 20 has elastic plates 21 and 22 of the same size made of a constant-elasticity metal material, and piezoelectric ceramic piece 23 providing electrical/mechanical energy conversion in thickness silding vibration mode for inflectional vibration. Ceramic piece 23 is cascaded between elastic plates 21 and 22, allowing its residual polarization direction (shown by the arrow) to agree with the length direction of converter 20, to obtain a tuning-fork type converter. On flanks 23a and 23b of ceramic piece 23 nearly perpendicular to the displacement direction of the converter, thin electrodes 26 and 27 are provided and between input terminals 24 and 25, a voltage of a fixed frequency is applied to vibrate converter 20 in the mode as shown by dotted lines through the thickness sliding vibration of the piezoelectric ceramic piece. This constitution eliminates the need to pay attention to the combination direction of the piezoelectric ceramic, simplifying a fabrication process.

摘要： PURPOSE:To prevent the generation of cracks in a junction part between lead terminals and a circuit substrate, an insulating member, etc., by arranging, outside the insulating member, a part from the middle portion of a lead terminal retained by the insulating member to an external end of the lead terminal, and separating said part from the insulating member. CONSTITUTION:A part 14a, 14b from the middle portion of a lead terminal 14 retained by an insulating member 13 to the external end of a lead terminal 14, is arranged outside the insulating member 13, separated therefrom, and bent in the form of a crank. Therefore, when the bottom part 14d of external end-portion side of the lead terminal 14 is soldered against the conductor pattern 19 of a circuit substrate 18, distortion mainly caused by the difference of thermal expansion coefficient between the insulating member 13 and the circuit substrate 18, can be absorbed by the parts 14b, 14c of the lead terminal 14 which are positioned outside the insulating member 13. Thereby, the generation of cranks in a junction part between the lead terminal and the circuit substrate, the insulating member, etc., can be prevented.

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 obtain a crystal temperature sensor chracterized by high resolution, excellent linearity and a short measuring time of temperature change, by obtaining the output signal of the frequency difference between the oscillating frequencies, which are outputted from a temperature sensing crystal oscillator and a reference crystal oscillator. CONSTITUTION:It is desired that the temperature characteristics of temperature sensing crystal vibrator is as linear as possible and the slant is large. As a crystal vibrator which satisfies these conditions, there are cut crystal vibrators and the like. As the crystal vibrator used in a reference crystal oscillator 2, the crystal vibrator, which has very small frequency change due to the temperature change, is selected. When an AT cut crystal vibrator is selected, one having almost no frequency change is obtained. The sensor is used in the deep part of the sea where the temperature range of the sea water is 2+ or -5 deg.C with an allowance. The width of the frequency change of the reference crystal oscillator 2 in said temperature range is very small in comparison with the width of the frequency change of the temperature sensing crystal vibrator 1, and satisfies the conditions. Therefore, the frequency of the temperature sensing crystal vibrator 1 is made to equal to the frequency of the reference crystal at the temperature at which the sensor is used.
