摘要： PROBLEM TO BE SOLVED: To provide a piezoelectric transformer which can boosts a voltage with high energy conversion efficiency. SOLUTION: A laminated piezoelectric transformer is manufactured in such a way that a laminated piezoelectric ceramic body 1 is obtained by alternately laminating piezoelectric ceramic layers 1a respectively carrying input-side internal electrode layers 2a and 2b and output-side internal electrode layers upon another and, after the laminated body 1 is baked, input-side external electrodes 3a are formed on both end faces of the body 1 in the widthwise direction on which the internal electrode layers 2a and 2b are exposed. In addition, an output-side external electrode 3b is formed on one end face of the body 1 in the lengthwise direction. Then the piezoelectric ceramic layers 1a between the electrode layers 2a are polarized by applying a voltage across the input-side external electrode 3a and, thereafter, all piezoelectric ceramic layers 1a between the output-side internal electrode layers and input-side internal electrode layers 2a and 2b are polarized.

摘要： PROBLEM TO BE SOLVED: To provide a piezoelectric transducer which has less deterioration in property due to polarization processing. SOLUTION: A plurality of driving electrodes 11, 12, 13 and 14 are polarized in the same direction, and oscillation node positions of the driving electrodes 11, 12, 13 and 14 are alternately insulated so that an input signal is alternately connected to the adjacent driving electrodes. The driving electrodes 11, 12, 13 and 14 are connected by substantially U-shaped driving terminals 15a, 15b made of an elastic material. Thus, the plurality of driving electrodes 11, 12, 13 and 14 may be simultaneously polarized. In addition, the processing for connecting the adjacent driving electrodes after polarization is omitted and simplification of processes is thus realized. At the same time, an inexpensive and highly reliable piezoelectric transducer may be provided.

摘要： PURPOSE: To provide an acoustooptical element for controlling the intensity or the direction of a laser beam stable in operation and high in impact resistance. CONSTITUTION: A fixed component 13 is constituted so that the cross section thereof is L-shaped and one end thereof is brought into contact with a case frame 12. Then, the contact point thereof is defined as a supporting point, the fixing part of the component 13 for fixing an acoustic optical medium 11 is defined as the point of application and the insertion part of the screw 14 of the component 13 is defined as a force applying point. Since the height of the fixing part of the component 13 for fixing the medium 11 is uniformized by arranging the force applying point between the supporting point and the point of application, the holding force of the medium 11 is uniformly added to the medium 11. As the result, the distortion of the medium 11 is eliminated and the impact resistance is enhanced.

摘要： PURPOSE:To prevent the sensitivity of a sensor from deteriorating by sandwiching an oscillator mounted on a mounting substrate between projecting portions provided to a case. CONSTITUTION:An oscillator 2 is sandwiched between the projecting portions 1a, 1b of a case 1 with the front and back projections of the oscillator 2 fitted between the projecting portions 1a, 1b of a case 1. The projecting portions 3a, 3b of a mounting substrate 3 are pressed and fitted around the outer peripheries of the projecting portions 1a, 1b, to energize the projecting portions 1a, 1b toward the oscillator 2, and under these conditions the case 1 is bonded to the substrate 3 by an adhesive 4. Therefore, the oscillator 2 is sandwiched between the projecting portions 1a, 1b without the use of adhesives. Thus the holding area of the oscillator 2 is not made greater than is designed, and the oscillator readily undergoes deflection according to external stresses, whereby an output electromotive force (sensitivity) can be prevented from deteriorating or varying.

摘要： PURPOSE:To facilitate the assembling of an ultrasonic delay medium and to ensure the long time reliability by pressing a background electrode, an electrode of an input output transducer and an upright projection of a lead frame terminal into contact through the contact of a metal made spring. CONSTITUTION:An ultrasonic delay medium 16 is assembled in a case 11 and input output transducers 18a, 18b are bonded onto background electrodes 17a, 17b. When the medium 16 is assembled in the case 11, upright projections 12a, 15a of lead frame terminals 12, 15 are in contact with the electrodes 17a, 17b and upright projections 12a, 15a of lead frames 13, 14 are in contact with the electrodes 19a, 19b of the transducers 18a, 18b respectively. A metal made spring 20 is an L-shaped spring in contact with two adjacent end faces apart remotest from a slope end face on which the transducers 18a, 18b are bonded. Then an undesired signal absorbing member 21 is coated to a side face of the medium 16. The assembled medium 16 is pushed by the spring 20 to press the electrodes 17a, 17b, the electrodes 19a, 19b and the upright projections 12a-15a into contact with each other.

摘要： PURPOSE:To make a piezoelectric relay resistible to dust and humidity and easier for handling by setting the piezoelectric unimorph provided with a traveling contact from a flat opening in the casing thickness direction of a casing case, and installing another sealing cover in the flat opening of the casing case. CONSTITUTION:A piezoelectric unimorph 5 is made up into a form similar to the disc or the round form that stuck a flexible plate consisting of a sheetlike piezoelectric element 6 and a conductive material of metal or the like. And, a traveling contact 8 is attached to a tip of the unimorph 5, while a casing case 9 cases the unimorph 5 and it is set in from flat opening in the casing thickness direction, fixing 1/3-1/5 or so of the outer diameter of the unimorph 5 to a support part 9a of the case 9. And, the flat opening of the case 9 is sealed with a sealing cover 11. When 1/3 or so of the outer diameter is supported and fixed like this, displacement and displacement load of the unimorph 5 can be efficiently taken out, thus such a piezoelectric relay that is resistible to dust and humidity owing to the sealing cover is produced.
