摘要： An acoustic transducer comprising a housing, and first and second stacks ofransduction plates disposed within the housing for engaging opposed wall portions of the housing, the first and second stacks being adapted to be held in compression between the housing opposed wall portions. A threaded stud extends from the first stack to the second stack, and a nut is threadedly engaged with the stud and adjacent one of the stacks. Movement of the nut on the stud operates to move the stacks toward the housing walls, respectively, to compress the stacks, and operates to relax compressive force on the stacks to enable withdrawal of one of the stacks and replacement thereof.

摘要： An acoustic transducer is constructed as a stacked configuration of multiyer transducer elements separated from one another by an electrical insulating material. Each multi-layer transducer element has a layer of acoustically transparent electro-acoustic transducer material having opposing planar surfaces with electrically conductive material deposited thereon. For each multi-layer transducer element, the electrically conductive material is formed into parallel strips electrically isolated from one another on at least one of each element's opposing planar surfaces. The parallel strips associated with each multi-layer transducer element have a unique angular orientation.

摘要： An ultrasonic transducer for controlling an elevation aperture utilizes the electric field-induced polarization properties of relaxor ferroelectric materials. The Curie temperature of the material is typically close to room temperature, so that the application of a bias voltage provides piezoelectric activity. By varying the thickness of a dielectric layer that spaces apart the relaxor ferroelectric material from an electrode or providing the bias voltage, the piezoelectric activity can be tailored. That is, degrees of polarization of the relaxor ferroelectric material are varied spatially in correspondence with changes in thickness of the dielectric layer. The effective elevation aperture of the transducer can be varied by adjusting the bias voltage.

摘要： The metal-ceramic actuator includes an electroactive substrate having at least a pair of opposed planar surfaces and a determined thickness, with the ceramic substrate being poled in its thickness dimension. Conductive electrodes sandwich the ceramic substrate and are bonded to its planar surfaces. Metal caps, each having a concave cavity bounded by a rim, are bonded to both planar surfaces of the ceramic substrate. A potential is applied to the conductive electrodes to cause an expansion of the ceramic substrate in its thickness dimension and a concomitant contraction in its planar dimensions. The contraction creates a flexure of the metal caps, which flexures are used to actuate another instrumentality.

摘要： This invention is for a single lamina twisting transducer made of an electrodeformable material. The twisting transducer has responsivity vectors which are curved or circular in nature so that when an electric field is applied the transducer will twist, exserting an angular force rather than a linear force as prior art transducers do. The twisting lamina can be stacked with a common electrode between them. The transducers can be used in actuators to provide angular forces in actuators. When combined in actuator stacks with linear transducers the actuator stack can be controlled in six degrees of freedom. Thus accurate moving and positioning of objects can be accomplished by use of such an actuator stack. Further since such an actuator stack is sensitive to accelerations in six degrees of freedom it can be used in making an accelerometer. Other uses for twisting actuators are for motors and rotational positioning of objects.

摘要： An acoustic transducer for providing large displacements particularly at low acoustic frequencies is formed from a minimum of three curved shells which are attached to each other at their ends. The shells are driven by a ring or corresponding number of attached piezoelectric or magnetostrictive type rod or bar drivers. The curved shells are attached to the ends of the driver and vibrate with a magnified motion as the rods execute extensional motion. As the polygon expands the curved shells deform and produce additional motion in the same radial direction resulting in a large total displacement and corresponding large acoustic output.

摘要： A vibratory transducer comprising a vibratory beam composed of an n-type layer and having at least one end fixed. The vibratory beam is formed by selectively etching an n-type layer formed by adding impurities locally to a single silicon crystal. The vibratory transducer also comprises means for vibrating the vibratory beam and means for detecting vibration of the vibratory beam. The vibratory transducer measures pressure, temperature, density, etc, by detecting change in the resonant frequency of the vibratory beam. The vibratory beam can be finely etched irrespective of the density of the impurities therein by forming the vibratory beam in an alkaline aqueous solution while applying a negative DC or pulsed voltage to a p-type layer and a positive DC or pulsed voltage to an n-type layer. The vibrating and detecting means for the vibratory beam can be easily provided by making a diode and a transistor including the vibratory beam in the transducer.

摘要： The present invention relates to a beam forming device for forming a uniform radiation beam and/or a reception beam. In radiation, the transducer is vibrated in such a way that the pressure of a sound wave produced from each point of the vibrating surface of the transducer is determined based on a weight function, thereby forming a radiation beam. In reception, electric signals are derived based on the sound energy received in a manner that the amplitude level of an electric signal produced based on the sound energy received by each point of the vibrating surface of the transducer is determined based on a weight function, and the derived signals are combined with one another to form a reception beam.
