When the pipe is corroded after the surface thereof is ground and mirror finish polished, a replica of the micro texture in the pipe is formed. Carbide is extracted from the ground powder generated at the time of grinding the pipe, and then an analysis of X-ray diffraction is applied thereto. The ground powder is dissolved with phosphate, and the solution is filtered by a filter to collect the remainder, and then the content of the remainder and the lattice constant is measured while the identification of the remainder is made, and also the relative amount is measured. Thereafter, it is determined whether the subject is in a range of experience to which a remaining service life determination method can be applied, or not.  Then, the ovservation of micro texture of replica and the comparison with data obtained formerly are carried out, and the relative amount of carbide and the lattice constant are compared with those taken preliminarily from the material used for a long time. Accordingly, degrading can be estimated.

Title: Eddy current detection element and production thereof
Inventor: HAMAZAKI YUKIO
IPC: G01N27/90
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To realize highly accurate inspection in a tube by arranging a permanent magnet or an electromagnet on the periphery of a coil in an eddy current detection element and bringing the eddy current detection element into tight contact with an object thereby preventing the element from floating. SOLUTION: A permanent magnet 18 or an electromagnet is arranged on the periphery of a coil 14 in an eddy current detection element 10. Since the permanent magnet 18 has no effect on the sensitivity of sensor, a strong permanent magnet is preferably employed so that the element 10 is brought into tight contact with an object. The coil 14 in the element 10 is fed with an AC current and generates an AC field. Since the field generated from the magnet 18 disposed around the coil 14 does not vary with time, it can be brought into tight contact with the wall face of element 10 without having any effect on the measurement.  Even if the element 10 fixed to a sensor jig 60 is floated due to inclination of the shaft 30, the magnet 18 arranged around the coil 14 is attracted tightly to the wall face of element 10 and prevents the element 10 from floating thus realizing highly accurate flaw detection.

Title: Lissajous's circle display signal circuit
Inventor: YAMAUCHI YOSHITAKA
IPC: G09G1/12
Filed: 1986-10-15
Abstract: PURPOSE:To shorten a stand-by time for displaying a Lissajous's circle, by multiplying a reference sine wave by a data numerical value at a phase point where the amplitude of the reference sine wave is near to zero. CONSTITUTION:A zero point detection circuit 8 always detects the zero point of a reference sine wave and a latch signal delayed by an angle theta is outputted by a timing circuit 9 with the detection of said zero point. Now, when a data numerical value R is transmitted from a data processor at the arbitrary point of time, the data numerical value R is latched by the latch signal immediately after said point of time and immediate inputted to a multiplier 3. The time during this period is extremely short, therefore, the operation timing of the multiplier 3 is always performed in the phase of the angle theta of the reference sine wave. Since the angle theta is a small value of pi/4 or less, the continuing time of a transient state is short and data is Letermined by the next cycle of the reference sine wave.
