摘要： PROBLEM TO BE SOLVED: To provide a method and device for detecting conditions of pipes or plates for uniformly and efficiently detecting the entire inner surface conditions of the pipes by an extremely simple method.
SOLUTION: The method detects the conditions of pipes by emitting an ultrasonic wave to a pipe thick-wall part to analyze a reflected wave from a discontinuous part of the pipes, and is characterized by: calculating, as difference waveform data, differences between initial waveform data which are initial data on the reflected wave and monitoring waveform data which are waveform data on the reflected wave collected after a lapse of a certain time period from the collection of the initial waveform data; comparing echoes of the difference waveform data with a previously set reference echo; and detecting a diminution in thickness of the pipes when the echoes of the difference waveform data exceed the reference echo.

摘要： PURPOSE:To eliminate wasteful movements of supply water, fuel, and air and attempt to improve the operation of a thermal electricity generation by the constitution that, when a target value of load varies, a subtractor sends the variation width of the difference of held load instruction signals and a target load value to a function generator and a preceding control signal is corrected. CONSTITUTION:A variation rate limiting device 5 holds its output for a specified time as soon as a target load value 15S varies. And, a subtractor 6 inputs a held load instruction signal 10S and the target load value 15 and inputs the variation width 16S of the difference between them to a function generator 4. The function generator 4 inputs a correction value 17S from 0.2 to 1.2 to a multiplier 3 according to input, and the correction value is multiplied by output signal of a differentiator 1 and the multiplication is inputted to each proportion calculator 2. With this arrangement, when the load variation width 16S is small, 0.2 is taken is a correction value 17S and it is multiplied to make each of preceding control signals 11S-13S small and when the width 16S is large, a corresponding large value is multiplied to make each of the preceding control signals 11S-13S large in order to make it possible to provide a preceding control signal output that is most suitable for any load variation pattern.
