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.

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： The surface of a specimen to be inspected is irradiated with a light having an intensity which varies from a position distant from the material, so that ultrasonic beams are generated in the material to be inspected. A coherent light is also projected onto a fixed surface provided at a given position and onto the surface of said material to be inspected. Vibration generated in the surface of said material due to ultrasonic beams reflected by a defect in the material, is detected in the form of change in phase of the coherent light that is reflected by the surface of the material. The change of difference in phase between the coherent light reflected by said fixed surface and the coherent light reflected by the surface of the material is measured with the lapse of time, in order to detect the flaw.

摘要： A digital type ultrasonic holography apparatus includes a clock generator for generating a clock pulse signal having a fixed period, a transducer for transmitting spike-like ultrasonic pulses toward an object in synchronism with trigger pulses derived through the frequency division of the clock pulse signal and receiving the reflected wave from the object, a waveform shaping circuit for shaping the received wave into a digital pulse signal, a coincidence detecting circuit for narrowing the pulse width of the digital pulse signal to a magnitude shorter than the period of the clock pulse signal and judging whether or not the pulse width-narrowed digital pulse is present at the level-changing time of the clock pulse signal, thereby to generate a coincidence signal, a scanner for scanning the transducer, and a device for displaying a hologram of the object in accordance with the value of the coincidence signal and the scanning of the transducer. The ratio of the interference fringe occupied portion of the displayed hologram to the remaining portion thereof is determined by the narrowed pulse width of the digital pulse.

摘要： A two-probe ultrasonic flaw detection apparatus, in which an ultrasonic wave is transmitted from a transmission probe into an object being inspected and ultrasonic waves reflected from a reflection surface in the object are received by a reception probe, operates to determine the position at which the combined intensity of ultrasonic waves reflected from each part of the reflection surface form a maximum. The reception probe is then moved to the position of maximum reception intensity. The position of maximum reception intensity is determined using as input parameters the ultrasonic characteristics of the object being inspected and of the transmission and reception probes, and the position of the transmission probe and the angle of incidence of the ultrasonic wave into the object.
