| PURPOSE: To remove an aging effect and to obtain spatially uneven radiation characteristics by using a composite fiber material aligning at least one layer of a piezo-electrically inactive plate to a main direction. CONSTITUTION: A composite fiber material aligning at least one layer of a piezo-electrically inactive plate to a main direction is used. For instance, a place piece 10 consisting of piezo-electric ceramic such as lead zirconate titanate is fixed on a piezo-electrically inactive multi-layer plate 11 and the plate 11 and the piece 10 are combined to form and a diaphragm 2. The 1st part 111 of the plate 11 consists of the composite fiber material and its 2nd part 112 also can be used as a constitutional part of the plate 11. Consequently spatially uneven characteristic can be obtained and the characteristic is not lost by an aging effect. COPYRIGHT: (C)1989,JPO | ||||||

| Electronically focused and automatically scanning acoustic bulk waves are produced by scattering chirp acoustic bulk waves at grazing incidence from an acoustic grating. The same apparatus may be used in reverse to convert diverging acoustic bulk waves produced by a focused beam into chirp acoustic bulk waves. A pulse compression filter then converts the chirp waves into signals describing the source. | ||||||

| PURPOSE: To make a side lobe value small and obtain a stable beam formation by bonding a piezoelectric ceramic oscillator to an inner side of a bottom surface part of a case of truncated cone shape in section, and by holding the case by a resilient oscillation preventing body having an ellipsoidal hole of a longer major axis and minor axis than the diameter of the bottom surface part. CONSTITUTION: An oscillator 3 is bonded to an inner side of a bottom surface part 1 of a case 2 of truncated cone shape in section, and the case 2 is held by a resilient oscillation preventing body 7 having an ellipsoidal hole 8 with a major axis (a) and a minor axis (b) which are larger than the diameter of the bottom surface part 1 of the case 2 and shorter than an opening end diameter and an acoustic tube 10 is formed by the ellipsoidal hole 8. A lead wire 5 connects respectively the oscillator 3, the case 2 and an output terminal 6. Thereby, the size and a vertical and horizontal direction ratio of the ultrasonic beam can be selected, a side lobe value can be made small to obtain a stable beam formation.

| PURPOSE: To give directivities different from each other in rectangular biaxial directions by forming the oscillating face of a diaphragm into an anisotropic plane having the direction of a major axis and the direction of a minor axis in a rectangular biaxial coordinate system. CONSTITUTION: A diaphragm 8 is formed on one end face of a cylindrical supporting body 7 as one body, and a piezoelectric oscillator 9 is stuck onto an oscillating face of the diaphragm 8. The oscillating face 81 of the diaphragm 8 is formed into an elliptic plane having a major-axis direction Y and a minor- axis direction X, and the piezoelectric oscillator 9 is stuck to the about center of this plane with an adhesive or the like. With respect to a means which forms the oscillating face 81 of the diaphragm into an elliptic shape, an inside hole 71 of the supporting body 7 is formed to an elliptic shape and the oscillating face 81 of the diaphragm 8 is formed to close this elliptic inside hole 71. Thus, the oscillation range of the oscillating face 81 in the major-axis direction Y is extended up to the peripheral part, and the oscillation range of the oscillating face 81 in the minor-axis direction X is concentrated to the center part where the piezoelectric element 9 is stuck.

| PURPOSE:To raise the resonance frequency, and also to make it a wide band and flat by propagatig the driving force uniformly and simultaneously to the whole nodal circle of a disk diaphragm, and also constituting the nodal circle part so that it scarcely cause deformation by shear and compression. CONSTITUTION:Plural radially pierced straight lines or circular arc-like slits 13 are provided so as to contact at right angle with a nodal circle 12 of the primary resonance mode of a disk diaphragm of a sandwich structure, plural ribs 14 which are obtained by forming aluminum, plastic, etc. are inserted into these slits, and this rib 14, surface materials 9, 9' and a core material 10 are made to adhered to each other. In this way, driving force F can be transmitted uniformly and simultaneously to the whole nodal circle of the diaphragm, and both the surface materials 9, 9', the core material 10 and the rib 14 are joined and held, therefore, the flexural rigidity becomes large and the resonance frequency fh also becomes high. A shift of the driving circle part of the disk diaphragm 1 is scarcely generated in the same way. | ||||||
