摘要： PROBLEM TO BE SOLVED: To reduce stress generating in a measurement pipe by suppressing the vibration of measurement pipes due to pressure pulsation.
SOLUTION: To the measurement pipe 17 connected with a diffuser 7 of a jet pump, a vibration suppressing device 19 constituted by connecting a cramp part 20 to a wing plate 21 by way of a connection part 22 is attached. When the measurement pipe 17 vibrates due to pressure pulsation during plant operation, owing to occurrence of friction between the measurement pipe 17 and the wing plate 21, vibration energy diffuses, attenuation of the vibration of the measurement pipe 17 increases and vibration response is suppressed. By this, the stress generated in the measurement pipe 17 can be relaxed.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for measuring a distance to an object, or oscillating displacement by transmitting ultrasonic waves toward the object to be measured and measuring time of arrival of their reflected waves.
SOLUTION: In this method for measuring oscillation, the oscillation of a structure in a container is measured from the outside. Received waveforms are orthogonally projected on a vector space spanned by M pieces of different waveforms having shifted times from a fundamental waveform measured beforehand. The M pieces of the time of the arrival are estimated so as to make the similarity between the waveforms determined by orthogonal projection and the received waveforms maximum, and the oscillating displacement is measured from the time of the arrival. This invention includes its device.
