Ferritic heat-resistant steel having excellent high temperature strength

High-strength ferritic heat-resistant steel and method of producing the

Disclosed is a method of predicting the remaining lifetime of a metal material, wherein the shapes of grains of the metal material are quantitatively measured to obtain variations in the shapes of the grains, and the remaining lifetime of the metal material is predicted on the basis of the variations. In accordance with the present invention, it is possible to statistically arrange the variations in the shapes of the grains by measuring such variations sequentially in time.

In a device for measuring motion of living body organs, an essential part which defines the oscillation frequency of the oscillator circuit of the device for measuring same comprises an electro-mechanical oscillator of a quartz resonator and impedance elements as coils or capacitors. The motion of organs on a living body surface or in a living body causes impedance changes in an impedance element and therefore, the detector is capable of detecting and measuring living body organ motion through a change in frequency.
