摘要： A device and a method for detecting main acoustic indexes of multi-beam sonar pertaining to the field of hydrographic surveying and charting technology. The device includes a rotating device and a lifting gear installed in an anechoic tank. The bottom of the rotating device is equipped with a multi-beam sonar that has its rotating plane perpendicular to the direction of track line and transmits signals along the horizontal direction. A standard hydrophone is equipped at the bottom of the lifting gear, and is connected with a signal collector. The device utilizes the standard hydrophone to receive the pulse signals transmitted by the multi-beam sonar and employs the multi-beam sonar to receive the standard sound source signals, designs the detection process for data collection for analysis and research, thereby achieving the detection of the frequency, source level and beam angle of multi-beam sonar.

摘要： The disclosure is directed to a method and apparatus for determining the velocity of a material within a body, and which is also capable of simultaneously imaging sections of the body. In the velocity-determined method, a focused beam of ultrasound is directed, over a given aperture, toward the skin of the body, the central ray of the focused ultrasound beam being oriented substantially normal to the skin. The ultrasound beam reflected from the body is received over the same aperture. Preferably, the steps of directing and receiving the ultrasound employ the same single transducer, and focusing is achieved using a focusing lens. Beat frequency signals are detected in the received beam, these signals resulting from the beating of Doppler effect components reflected from the moving material, for example, blood corpuscles of moving blood within the body. Velocity-representative indications, for example, audio or video presentations, are then generated as a function of the detected beat frequency signals. The detected beat frequency signals are beats between Doppler effected portions of the received ultrasound beam which have frequency components above and below the frequency of the originally directed ultrasound beam.

摘要： A method, a device and a transducer for dimensional measurement of objects by means of ultrasonics, where the objects are carried past at least an ultrasonic measuring device consisting of a combined transmitter/receiver or separate transmitter/receiver. The reflected ultrasonic signals are used to determine characteristic three-dimensional dimensions of the objects. Said device or devices are arranged either such that the ultrasonic beam or beams therefrom are provided with a reciprocating movement which substantially crosses the direction of movement of the objects or by letting the ultrasonic beam or beams therefrom be stationary. The delay of the reflected signals is used to form a three dimensional image of the object by means of a computer, said image being compared with known images for identification. The ultra sonic measuring device has a narrow, substantially rotation-symmetric radiation diagram. The ultra sonic radiation is directed downwards towards the conveying path through provision of means arranged above and at a distance from the objects to be measured. The transducer uses air as propogation medium and is arranged at a distance from the objects to be dimensionally measured. The transducer consists of an electro-acoustic oscillator arranged coaxially with the centerline of a substantially conical ultrasonic reflector, the angle of aperture of the reflector relative to the center line through the reflector being equal to 45.degree.. The transducer provides ultrasonics having a wavelength in the range of 0.1 to 5 mm, preferably 1.1 to 1.4 mm.

摘要： The disclosure is directed to an apparatus for imaging a body, such as an ultrasonic imaging system. In the disclosed apparatus, means are provided for transmitting energy, such as ultrasound energy, into the body. A transducer is provided for converting energy reflected from the body, typically ultrasound echoes, into electrical signals. The transducer, which is divided into a plurality of defined segments, such as concentric annular segments surrounding a central circular segment, is utilized for both transmitting and receiving. A plurality of register devices are provided, preferably analog registers of the charge-transfer type. The input of each of the register devices is coupled to a respective one of the transducer segments. A first clock is associated with each of the register devices. A plurality of second clocks are also provided, each being associated with one of the plurality of register devices.The second clocks have different characteristic clock rates. Timing means are provided for effecting clocking of the electrical signals from the segments into their respective devices with one of the device's associated clocks (i.e., either the common first clock or the device's associated second clock) and for subsequently effecting the clocking of the stored information out of each of the devices with the other of its associated clocks. Finally, means are provided for combining the signals clocked out of the devices to form an image-representative signal. In the present disclosure, the increasing or decreasing delay associated with the different transducer elements, as is required for dynamic focusing, is achieved by utilizing signals of slightly differing frequencies (e.g. the second clocks) so that, as time passes, the cumulative difference in sampling times for the different registers "builds up" to provide the desired variable delay.

摘要： An improved power semiconductor device and manufacturing method are described wherein the external, thermally conducting, heat transfer face of the device is electrically insulated by a glassy dielectric which is intimately bonded directly to the conductive heat spreader supporting the semiconductor die. By forming the exposed corners of the heat spreader to be substantially smooth curved surfaces having a predetermined minimum radius of curvature greater than the thickness of the glassy dielectric, formation of a ridge of glass at the corners and edges of the heat spreader is avoided. For ease of assembly the piece parts are initially substantially flat and parallel. A molding compound of controlled shrinkage is used to avoid distorting the substantially flat smooth insulated heat transfer face which remains exposed in the encapsulated device.

摘要： In an ultrasonic scanner, a plurality of sound transducers are operable to project sound beams defining spaced sound paths into a sectional plane of an object and to receive echoes therefrom. The sound paths may be oscillatingly swept in the sectional plane during operating cycles so that the sound path of each sound transducer coincides at least once during each oscillating cycle with a predetermined line of reflection in the sectional plane. A fluorescent screen receives some of the echo signals to display them in a section scan mode while a sound transducer control operates each sound transducer when none of the sound paths coincides with the predetermined line in each given cycle. A scan mode control operates when the sound path coincides with the predetermined line for displaying the section scan mode in response to the echo signals in a different scan mode several times per cycle.

摘要： The disclosure is directed to an apparatus for scanning an object with a beam of ultrasound energy and for formulating image-representative signals from the ultrasound reflected from the object. An ultrasound reflector is disposed in the path of the ultrasound energy, the reflector typically being disposed in a suitable fluid, for example water. The reflector is mechanically driven and means are provided for sensing the relative angular position of the reflector and for generating a first clock signal as a function of the sensed position. Means, responsive to the ultrasound reflected from the object are provided for generating echo-representative electrical signals. These echo-representative electrical signals are stored at a line rate which depends upon the first clock signal. Finally, means are provided for reading out the stored signals at a line rate which depends upon a second clock signal, and for displaying the read out signals to obtain an image of the object, the line rate of the display being synchronized with the second clock rate.
