摘要： Ultrasonic waves from a transmit device are transmitted to an object subject to measurement. A surface reflected wave propagated in a contact medium and reflected at the surface of a tube and bottom surface reflected waves passing through an oxidation layer on the tube and reflected at the inner surface of the tube are convened into electric signals. A feature extracting part 5, in consideration of a correlation relationship of energy with respect to the frequency of a received signal, based on the received signal of ultrasonic waves converted to electric signals, extracts a signal feature data determined beforehand which has a strong correlation relationship with the thickness of a measured part. Based on the extracted signal feature data, a thickness conversion part references a relationship storage part which has stored therein beforehand a function that shows a relationship between the signal feature data and the thickness of the oxidation layer, and obtains the thickness of the oxidation layer.

摘要： An object detecting method and apparatus is disclosed and which operates by transmitting a wave toward an object embedded in a medium having a reflective coefficient at its surface, receiving the resultant reflected wave from the object, applying the received signal to a signal processing unit, and displaying the results of signal processing by the signal processing unit on a display unit. The apparatus and method, furthermore, incorporates the means or steps of multiplying the received signal by a reference signal corresponding to the high frequency wave of the radiation energy and with its phase shifted by a controlled amount, so that the frequency of a signal component included in the received signal as a result of wave reflection from the surface of the medium is converted into a frequency which can be removed by a low-pass filter, passing the resultant received signal through the low-pass filter, and applying the output signal of the low-pass filter to the signal processing unit for processing a clear and sharp image reproduction of the object on a display.

摘要： Disclosed is a picture display apparatus connected to a low resolution ultrasonic inspector so as to display a picture with high resolution. In the apparatus, an approximate spectrum of a theoretical spectrum representing an object having a known shape as a reference and a spectrum obtained through measurement of the known-shaped object are subject to Fourier transformation so that a transfer function of a measurement device is calculated from the ratio between the respective values obtained through the two operations of Fourier transformation, whereby an unknown shape of an object is displayed on the basis of the transfer function and Fourier transformation values of a measured spectrum of the object having the unknown shape. A modified Gaussian distribution obtained by combining two Gaussian distributions, in which the transformation values of the spatial spectrum of the known shape are reduced in a high frequency range and in which oscillations are less spread in the high frequency range, is employed as the approximate spectrum of the theoretical spectrum representing the known-shaped object, so that the high frequency components of the spatial spectrum of the unknown shape can be reduced and therefore a clear picture can be displayed with high resolution.

摘要： Plant operating conditions 1, apparatus operating conditions 2 and environment conditions 3 are accumulated, combined and put together as a set of plant status variables 8 -through a monitor 6, while water chemistry information 4 is accumulated as another set of plant status variables 9. The set of status variables 8 is updated and the past data are accumulated in the set of status variables 9. Periodical inspection data 5 are also accumulated in the set of status variables 9 along with the water chemistry information 4. The set 9 is compressed and stored as a plant chart 11 such as a personal clinical chart. A status variable prediction 12 is performed in consideration of the personality of a plant. Both data of the sets 8 and 10 are compared with each other by comparison means 13. If both the data nearly coincide with each other, the plant is diagnosed to be normal and, if not, it is diagnosed to be abnormal. When the plant is diagnosed to be abnormal, an abnormal apparatus and an abnormal factor are identified.
