Abstract: PURPOSE:To evaluate a micro crack area due to hydrogen attack, which exists in a steel material, with a high precision by propagating ultrasonic waves in the thickness direction of the steel material and detecting propagation times of their longitudinal waves and transverse waves and obtaining a ratio of them. CONSTITUTION:Times when bottom echoes of the longitudinal wave and the transverse wave of an ultrasonic wave are received by a transmitter and receiver 3 after a transmission pulse is given from the transmitter and receiver 3 to a probe, namely, going and returning propagation times tL and tS are measured to obtain a ratio VL/VS of propagation speed. In this case, a speed ratio operating circuit 5 operates the speed ratio VL/VS on a basis of propagation times tL and tS, and the operation result is inputted as an address signal to a memory 6 where relations indicated on a characteristic graph are preliminarily stored. Then, value 0.5 indicating a proportion TA/T of hydrogen attack is read out from the memory 6 when the speed ratio VL/VS is, for example, 0.567. Thus, dimensions in the depth direction of a hydrogen attack area 2 in a steel material 1, namely, its layer thickness TA is evaluated accurately.

Abstract: PURPOSE:To detect an object correctly even when an infrared light generated by some cause acts as disturbance, in a detecting device of the object which uses the infrared light. CONSTITUTION:A microcomputer 22 detects the existence or nonexistence of disturbance on the basis of a light detection signal K1 at the time when light-emitting elements 6a and 6b emit no light.

When the disturbance exists, the existence or nonexistence of the disturbance is detected again on the basis of a light detection signal K2 at the time when the light-emitting elements 6a and 6b emit no light. When no disturbance exists then, the two light-emitting elements 6a and 6b are made to emit lights by the light emission command signal F of the fixed emission modulation frequency and the object is detected on the basis of the existence or nonexistence of the light detection signal K2. When the disturbance exists, the existence or non-existence of the disturbance is detected for a third time on the basis of a light detection signal K3 at the time when the light-emitting elements 6a and 6b emit no light.
