| PROBLEM TO BE SOLVED: To provide an acoustic radiating membrane for a music box or striking watch, made so as to provide uniform acoustic efficiency across the audible frequency band (1-4 kHz).SOLUTION: An acoustic radiating membrane (1) for a striking watch (10) includes areas (2, 3) asymmetrically formed in the material of the membrane (1). The thicknesses of the areas (2, 3) are different from the general thickness of the membrane. The areas (2, 3) have elliptical shapes. The areas (2, 3) with elliptical shapes are formed by hollowing out of the membrane (1) with uniform thicknesses different from each other, which are thinner than a bottom part (4) of the membrane (1). The two areas (2, 3) are partly superposed. | ||||||

| (57)【要約】 先細音響発振子（指向性スティック発振子、又は、スティック発振子として参照される）は、機械的波動を、直接、又は、随意的なアダプタ（１２）により、スティック状に設計された機械的導波路に励振又は伝播する励振器又は発振器エミッタ（１１）からなる。 それ故、機械的波動は、波速ｃ wで、導波路軸に沿って進む。 機械的波動は、導波路に結合された変成器素子（１４）の局所変位を生じ、それらは、音響放射に変成される。 導波路は、能動又は受動インピーダンス終端（１５）、例えば、無反射インピーダンス終端を用いて終端される。 局所的な音放射は干渉し、指向性の同相放射が後に続く。 入力インピーダンス、指向特性、同相領域、及び、放射効率は、励振点、機械的波動の波速、導波路長、変位の振幅、機械的音響的変成器の特性、及び、インピーダンス終端により調節できる。 囲いの容積は、導波路と変成器の特性により調節される。 指向性スティック発振子は、警告又は信号装置として、スピーチ又は音楽伝達のため、騒音打ち消しのために使用でき、及び、逆の動作で働く時は、指向性マイクとして使用できる。 | ||||||

| PURPOSE: To achieve the beam uniformity of an expansion transducer driven resonantly by fastening the longitudinal end periphery of a slender diaphragm more firmly relative to the base than to the side periphery in its width direction. CONSTITUTION: A conical diaphragm 12 of a transducer is set on the base 14, and secured by an integral clamping member 16. The base 14 provides an inner elliptical lip 26, and the circumference of the diaphragm 12 is mounted thereon. In the end peripheral area of the diaphragm 12, the lip 26 is formed aslant in the whole, and a complementary surface 30 is formed on the member 16 so as to form a firm clamp combination. Contrastively, in the side peripheral area, since the lip 26 has a more sharp contour shown in its surface 30, the clamp is not so firm. In this manner, it is valuable in a diaphragm having its length at least 1.2 times the width, and it is desirable that rigidity in the longitudinal direction is within 50% of the rigidity in the width direction. | ||||||

| PURPOSE: To improve the pickling speed of an edge part of a metallic sheet by radiating the ultrasonic wave in a plane parallel to the edge part of the sheet in the reactive solution to generate the cavitation in the liquid. CONSTITUTION: A metallic sheet 3, especially a hot-rolled sheet before cold rolling is immersed in the reactive solution 2 in a pickling tank 1. An ultrasonic wave generator 4 is immersed further in the reactive solution 2. Two expansion elements 6, 7 are mounted on an acoustic electrode 5 at a lower end part across the edge part of the metallic sheet 3. The flat radiation surfaces of the expansion elements 6, 7 are parallel to the metallic sheet 3, and contained in the wave antinode, and are oscillated in the antiphase mode. The ultrasonic wave is generated in the antinode plane parallel to the edge part to generate the cavitation in the liquid between the edge part and the expansion elements 6, 7. The frequency of the ultrasonic wave is approximately 10-50 kHz, and the output is preferably ≥400 W per 1 m 2 of the radiation area. COPYRIGHT: (C)1993,JPO | ||||||

| PURPOSE: To increase the quantity of produced snow and also to produce the snow of excellent quality being dried and formed in powder, by providing an ultrasonic oscillator for emitting an ultrasonic wave toward water droplet groups which are jetted by a jetting device for jetting water in atomization from a nozzle. CONSTITUTION: Water is jetted in atomization from a nozzle 3 at an ambient temperature of 0°C or below, water droplet groups 5 jetted are frozen and thereby snow is produced.

| PURPOSE: To improve the acoustic transducing efficiency and to suppress the resonance at high-pitched sound range by adopting three-layer structure for the diaphragm, forming the intermediate layer with porous diamond like substance and reducing the specific gravity of the entire diaphragm. CONSTITUTION: A speaker diaphragm 1 adopts a three-layer structure comprising a surface layer 2, an intermediate layer 3 and a rear face layer 4. The surface layer 2 and the rear side layer 4 are both solid and mode of a diamond like substance with no space nor air gap therein. The thickness of the surface layer 2 and the rear side layer 4 is selected normally 1-20μm. The intermediate layer 3 is made of a porous diamond like substance thin film. Then the porosity of the intermediate layer 3 is preferably 5-95vol.%. The thickness of the intermediate layer 3 is selected normally to be 5-50μm. Thus, the sound pressure level is improved more than a conventional diamond diaphragm and the resonance at high frequencies is less. COPYRIGHT: (C)1991,JPO&Japio | ||||||

| PURPOSE: To obtain a spacially uneven radiation characteristic and to remove aging by forming grooves arranged almost in parallel with each other at least on one surface of a diaphragm. CONSTITUTION: The diaphragm 2 is provided with a plate 11 consisting of a piezo-electrically inactive material, preferably a metal, and forming the bottom of a pot and a plate piece 10 consisting of a piezo-electric material such as piezo-electric ceramic and fitted to the plate 11. Grooves or slits 3 arranged almost in parallel with each other on the outer surface of the diaphragm 2 generates a result that a pot type converter has rigidity or sound velocity in one main direction 5 which is extremely smaller or lower than a value recognized in a main direction 4 vertical to the direction 5. Consequently spatially uneven radiation characteristic can be obtained. COPYRIGHT: (C)1989,JPO | ||||||
