摘要： PROBLEM TO BE SOLVED: To reduce power required to generate a cavitation and enhance a sterilization effect in an arrangement for sterilizing harmful microorganisms and bacteria by an impact pressure at the time of a collapse of cavitation.
SOLUTION: The harmful microorganisms are sterilized utilizing the impact pressure generated when a free vortex is generated in a swirl chamber 1, the center pressure thereof is reduced below a saturated vapor pressure to generate a swirl cavitation, an opposite swirl cavitation whose swirl direction is reverse to its swirl cavitation is generated and both swirl cavitations oppositely collide to cause an abrupt collapse of the cavitation.

摘要： PROBLEM TO BE SOLVED: To efficiently measure an above-ground part and the shape of the bed of a river by directly measuring the terrain by the laser beam relative to the above-ground part, and measuring the shape of river-bed by moving the ultrasonic beam relative to the underwater part. SOLUTION: A laser beam measuring device 6 is installed on an above-ground part 2 between a dike 1 and the river, and an ultrasonic wave transceiver 8 is floated on the water surface 3. The laser beam measuring device 6 determines a distance to a target by a sensor or the like, measures the angles between the target and the measuring device 6 in the vertical direction and the lateral direction by an azimuth finder or the like, calculates the shape of the river on the basis of the obtained data, and displays the same together with the map information. The ultrasonic wave transceiver 8 emits the ultrasonic wave toward the river bed 4, and receives its reflected sound. An ultrasonic measuring device body 10 comprisies a sensor formed by integrating the wave transceiver 8, a GPS for displaying the latitutde/longitude of a measuring point and the azimuth finder displaying the measuring direction, and measures the shape of the river bed on the basis of the reflection sound received by the wave transceiver 8.

摘要： PROBLEM TO BE SOLVED: To exterminate pathogenic insects and others simply by generating cavitation bubbles by emitting ultrasonic waves to drinking water to exterminate pathogens. SOLUTION: An ultrasonic apparatus having an ultrasonic sender 2 is disposed on the side of the passage 1 of city water pipe water, and part of the passage is irradiated with ultrasonic waves. The frequencies of the ultrasonic waves are made to generate ultrasonic wave surfaces 8 as indicated by a figure in part of the passage 1. Drinking water introduced from an introduction passage 4 is sterilized by being irradiated with ultrasonic waves while passing through an ultrasonic wave irradiation area 3 and discharged from a discharge passage 5 to be supplied for drinking. In this case, the ultrasonic wave surfaces 8 interfere with each other to generate sound pressure stripes, and bacteria passing through this part are allowed to be output without being broken. Therefore, the passage 1 is formed in the shape of a crank, the wide part of a crank part is made to be an irradiation area, and if ultrasonic waves are emitted perpendicularly to a water flow, a bacteria breaking effect can be improved further.

摘要： PROBLEM TO BE SOLVED: To constitute a monitoring system so as to prevent disasters by falling rocks, landslides, which detects a minute movement of an object to be monitored as a precursor of the disaster, predicts danger and quickly sends the information to stations concerned. SOLUTION: A technique for measuring a phase difference of ultrasonic waves is adopted thereby to measure a positional shift highly accurately. A small ultrasonic transmitter 2 is fixed to an object 1 to be monitored and ultrasonic signals from the transmitter 2 are received by an ultrasonic receiver 3 set at an observation point. Transmitting signals and receiving signals are transmitted via a signal cable or radio to a signal-processing circuit 6, where phases are compared. Data are sent to a data-processing device 7 and analyzed, and the result is stored in a memory device. This series of operations are automatically carried out, by a computer. In other words, the system can be used as an unmanned monitoring system. Measurements for the monitoring are executed automatically with a constant cycle. Data are not only sequentially stored in the memory device, but, compared with previous data. Comparison results are also stored in the memory device.

摘要： PURPOSE: To provide a high gradation and high speed magnetic resonance imaging device. CONSTITUTION: A weighting function w(t) is used to make a spin echo signal S(t) weighted, and a signal of frequency component of S(t).w(t) is made to exist in the neighbourhood of an objective signal frequency f0 . The form of amplitude weight w(t) is changed continuously so that the w(t) is minimized at the time of inversion of the gradient magnetic field and maximized at the middle time of inversion thereof. Futhermore, the frequency component of S(t) has the frequency component far distant from the objective signal frequency f0 when the weighting function w(t) is not used.

摘要： PURPOSE:To provide an ultrasonic device capable of measuring absolute blood pressure. CONSTITUTION:Doppler signals 14, 15 are stored in waveform memory sections 16, 17 and partial waveforms 18 of a temporarily stored signal 23 are subjected to Fourier transform and are stored in a Fourier memory section 20. A signal extraction section 21 selects the wide band signal part of the stored contents. The specific part of the temporarily stored signal 23 is selected as a reference signal 24 by a signal selection section 22. A correlation calculating section 26 calculates a corrective relation number 27 between the reference signal 24 and the temporary stored signal 25. A velocity calculating section 28 measures the pulse wave propagation time between measurement points 12 and 13 and calculates a velocity from the distance between the measurement points 12 and 13 by a distance deciding section 29. The absolute value of the blood pressure is determined from the velocity from the velocity calculating section 28 and the blood pressure from a blood pressure measuring section 44 as well as the change rate of the flow velocity of the blood based on the spectral information of the Fourier memory section 20 in a blood pressure calculating section 45 and is displayed on a blood pressure display section 46. As a result, the continuous measurement of the absolute blood pressure in the local capillary vessels and the deep part arteries is made possible.

摘要： PURPOSE:To effectively measure the temporal change of the speed of vector-like movement by time sequentially integrating two-dimensional signals with respect to a specific position. CONSTITUTION:By performing such operations that ultrasonic waves are transmitted and the reflected signals of the ultrasonic waves are received several times with a plurality of elements, the received signals of each element corresponding to distances in a specific direction are found time sequentially. Ordinary one- or two-dimensional Fourier transformation is performed on the found signals. Then the speed of vector-like movement is measured by integrating the two-dimensional signals obtained as a result of the Fourier transformation in a specific direction and time sequentially integrating the obtained two-dimensional signal with respect to a specific position. In addition, ultrasonic waves are generated in an objective area by vibrating part of an array type ultrasonic transducer 19 with a signal from a driving signal source 20. Signals from a reflecting body are inputted to a speed computing element 23 through an amplifier 21 and A/D converter 22. An arithmetic section 23 performs speed measurement processing, such as various kinds of Fourier transformation, integration, etc., and a displaying section 24 displays the processed results.
