    摘要: The present invention is directed to an ultrasonic flow rate measuring device capable of improving the measurement accuracy. Such an ultrasonic flow rate measuring device comprises first to third ultrasonic flow rate sensors in the measurement passage which are equipped with first ultrasonic wave transmitter-receivers and second ultrasonic wave transmitter-receivers. First to third ultrasonic wave propagation paths connecting the first ultrasonic wave transmitter-receiver and the second ultrasonic wave transmitter-receivers, respectively, intersect at different angles with the flow direction of fluid flowing through the measurement passages. The ultrasonic flow rate measuring device of the present invention obtains a flow rate measurement selectively from one of the first to third ultrasonic flow rate sensors in response to a flow rate Q.

    摘要: A difference in the thermal expansion coefficient between a casing and a piezoelectric body is adapted to be reduced by making an adhesive expand and contract, and this can prevent the separation of connection between the casing and the piezoelectric body and the damage of the piezoelectric body. As a result, the ultrasonic vibrator can be used over an extended period of time in an outdoor use environment.

    摘要: An ultrasonic flowmeter includes a flow passage and an ultrasonic transducer for measuring the flow rate in the flow passage wherein the ultrasonic transducer is equipped with a piezoelectric material having electrodes on the opposed surfaces thereof, one of which is used as an ultrasonic wave transmitting/receiving surface and faces the flow passage. The lengths of the sides of the transmitting/receiving surface is so determined that the vibration in the electrode direction is the main mode, preferably that the ratio of the lengths of the sides of the transmission/reception surface to the thickness is not greater than 0.8. Consequently, because the flow meter uses the thickness longitudinal vibration of the piezoelectric material as the main mode, the ultrasonic transducer has a high sensitivity, a high speed response and a small size and the ultrasonic flow meter has a high accuracy and is compact.

    摘要: An ultrasonic probe to be used for an ultrasonic diagnostic apparatus for obtaining an ultrasonic image. The ultrasonic probe comprises a catheter having a hollow tubing structure, a joint having a tubing structure and arranged to be at its one end portion connected to a tip portion of said catheter, a bearing connected to the other end portion of the joint, a rotating shaft inserted into the bearing to be rotatable and arranged so that a portion of the rotating shaft contacts with one end portion of the bearing, and a rotator connected to the rotating shaft and arranged so that one end portion of the rotator contacts with the other end portion of the bearing so that the bearing is interposed and supported between the portion of the rotating shaft and the rotator. An ultrasonic transducer is inserted into the rotator for transmitting and receiving an ultrasonic wave, a torque transmission shaft having a hollow structure is at its one end portion connected to the rotating shaft, and a guide wire is inserted into the hollow of the torque transmission shaft. A rotating force generated by a drive section is applied through the torque transmission shaft to the ultrasonic transducer whereby the ultrasonic transducer rotationally driven to perform a radial scanning operation. This arrangement allows a free movement of the guidewire within the catheter so that the catheter can easily be lead along the guidewire up to a target portion within a blood vessel.
