摘要： PURPOSE:To reduce thermal effect at the time of abnormal heating and to enhance and stabilize atomizing capacity, by supporting the outer peripheral end of a piezoelectric ceramic vibrator through a damper member and a ring. CONSTITUTION:In the ultrasonic vibrator used in an ultrasonic humidifier, a main electrode 2 is electrically connected to one surface of the piezoelectric ceramic vibrator 1 and an auxiliary electrode 4 is electrically connected to the other surface thereof through a fold-back electrode 3. Further, a circular partial electrode 5 is provided to the central part of said other surface and a metal thin plate 9 having a diameter larger than the outer diameter of the vibrator 1 is adhered to the surface of the main electrode so as not to attenuate the vibration of the vibrator 1 while a metal support ring 10 is fixed to the outer peripheral surface of said plate 9 through a damper material 11 comprising silicone rubber. By this structure, the abnormal heating of the vibrator 1 is absorbed and dissipated by the highly heat-conductive ring 10 and, because vibration is not attenuated, atomizing capacity is enhanced.

摘要： PURPOSE:To increase the heat radiating effect of a fixed base plate, miniaturize the unit and improve durability to self rupture remarkably by a method wherein liquid in a reserving tank is sucked and is reserved in a reservoir between the fixed base plate and a chamber base. CONSTITUTION:The liquid in the reserving tank 9 of a humidifier main body is sucked into the unit and is reserved in the reservoir 15 between the fixed base plate 13 and the chamber base 12. According to this constitution, the heat radiating effect of the fixed base plate 13 may be increased and the unit may be miniaturized while the structure may be simplified and the cost thereof may be reduced. On the other hand, overheating of a power transistor 5 may be prevented and the temperature of the fixed base plate 13 may be kept within the range of predetermined temperature, therefore, breakage of attaching section 12b of the humidifier main body may be prevented. When the liquid in the reserving tank 9 expires, a piezomagnetic oscillator 1 generates heat and causes self rupture, however, the durability for self-rupture may be improved remarkably by the liquid in the reservoir 15 around the chamber base 12.

摘要： PURPOSE:To make sensitivity high and to make a microphone compact by enlarging the amplitude of a bimorphe vibrator by the vibration interference of an inclined surface vibrating part provided in the outer periphery of the bimorphe vibrator and widening the outer peripheral end of the bimorphe vibrator upward or downward. CONSTITUTION:A vibration part is composed of a plane vibrating part 2a, for which piezoelectric vibrators are attached, and an inclined surface vibrating part 2b provided in the outer periphery and in this vibration part, a composite resonance is generated by the bimorphe vibrator. Then, by optimumizing the respective dimensions of the vibration part, the resonance is superimposed and resonance efficiency is improved. When using a vibrator 2 provided upward, the effect of a phone can be also obtained so as to efficiently reflect ultrasonic waves to be generated from a cone-shaped resonator 4. Thus, the shape of the microphone is made compact and the sensitivity is made high simultaneously.

摘要： PURPOSE:To attain small size and high sensitivity by using a cylindrical vibrator for the constitution of a bimorph vibrator, using the side of the cylindrical vibrator as the extension of the vibrator outside diameter and fixing the cylindrical vibrator of the bimorph vibrator. CONSTITUTION:The bimorph vibrator is formed in a piezoelectric vibrator 8 by sticking it to a bottom of a cylindrical vibrator 9 having an opening at one end and the thickness of the cylindrical vibrator 9, the outside diameter of the bottom and the height of the side set a natural resonance frequency. The conical resonator 11 is fixed to the center of the bimorph vibrator with an adhesives 12. Moreover, an annular recessed part is provided to a support 13 made of an elastic member and the opening of the cylindrical vibrator 9 is fitted to the recessed part and arranged on the support 13, which is fixed onto a terminal board 14. Thus, the side vibration interference of the bimorph vibrator using the cylindrical vibrator 9 acts onto the bimorph part as vibration amplification to attain high sensitivity.

摘要： PURPOSE:To provide performance of high reliability to a microphone by providing a throughhole to a vibration case, coating the piezoelectric diaphragm and its surrounding with resin so as to avoid a pressure difference against the fluctuation of external air such as temperature and moisture cycle. CONSTITUTION:Plural throughholes 8 are provided to a side of a vibration case 7. A piezoelectric diaphragm 9 is stuck to the bottom inner side of one end of the case 7 and an epoxy resin 10 is coated to the bottom of the case 7 and the entire surface of the piezoelectric diaphragm 9 to constitute a bimorph diaphragm section. A ring shaped vibration control body 11 is adhered and fixed to other opening of the case 7 to suppress high-order resonance and needless vibration of the bimorph diaphragm section. A terminal board 12 is fixed to the opening end of the vibration case 7 and the ring vibration control body 11 with an elastic adhesives 13. Since the gas flows through the throughhole 8 at the case side part, even when gas pressure changed or high humidity takes place, no effect is imposed and a mechanical impedance difference between the bimorph diaphragm part and the vibrator control body is taken larger to decrease the vibration interference thereby improving the vibration efficiency.

摘要： PURPOSE:To improve position recognizing accuracy by providing a plurality of first receivers which receive ultrasonic pulse signals, and providing a direction judging part which judges the phase difference between a plurality of the ultrasonic wave pulse signals from said first receivers. CONSTITUTION:Receivers 26 which are provided at a moving body 21 receive information from a fixed base 25 as the different ultrasonic wave pulse signals. The frequency of the ultrasonic wave and the delay time of the transmitted ultrasonic wave pulse signal are obtained based on the received ultrasonic wave pulse signals. Namely, the received signal is amplified in an amplifier part 27. The signal is made to pass a filter part 28 which distinguishes the frequency of the ultrasonic wave. Then, the signal is inputted into a direction judging part 29, and the frequency is determined. The direction of the moving body 21 (right and left and front and rear) is determined. Meanwhile, the distance between the fixed base 25 and the moving body 21 is judged based on the received signal which is inputted into a delay-time judging part 30 through the filter part 28 from the amplifier part 27. Furthermore, the results of the judgments of the direction and the distance measurement are added into a position recognizing part 31. Thus the moving body 21 can determine its own position.
