Abstract: PURPOSE:To make it possible to confirm the hardened degree of the inside of a solidified body from the outside of a solidified body container under the capped state by pressing an ultrasonic wave oscillator and a receiver to the facing surfaces of the solidified body, and measuring the ultrasonic wave propagating speed in the solidified body. CONSTITUTION:A container 5 filled with a solidified body is conveyed to a measuring position with an automatic conveying and positioning device 8. An ultrasonic wave oscillator 9 and an ultrasonic wave receiver 10 are automatically pressed to both surfaces of the container 5 with an ultrasonic oscillator and receiver setting device 11 with specified pressing force. An ultrasonic-wave-propagating-time measuring device 13 which is provided in an operating chamber 12 is operated. Ultrasonic waves are transmitted from the oscillator 9. The ultrasonic waves which are propagated through the inside of the solidified body are received with the receiver 10. Thus the ultrasonic-wave propagating time is measured 13 and inputted into an operator 14. The operator 14 computes the ultrasonic-wave propagating speed based on correlation with an ultrasonic wave propagating distance (computed based on the moving amounts of the oscillator 9 and the receiver 10). The hardened degree of the inside of the solidified body can be confirmed based on the value of the propagating speed and the correlation between the propagating speed and the hardened degree which have been obtained beforehand.

IPC: H04L27/00
Filed: 1988-09-28
Abstract: PURPOSE:To obtain a signal source for accurately set the S/N of the carrier by composing a system of a carrier signal generator, an attenuator, an amplifier, and an input power measuring means. CONSTITUTION:A system 10 consists of the signal generator 11 which generates the carrier, the attenuator 13 which has a predetermined attenuation factor, and the amplifier 15 whose noise index is already known. An analyzer or power meter 19 measures carrier signal electric power at the input 14 of the amplifier 15. A noise index meter 21 measures the noise index of the amplifier 15. A carrier signal side-band wave noise is held below the heat noise floor level of the attenuator 13 and the carrier signal generated by the signal generator 11 is therefore attenuated so that the carrier side-band wave noise is hidden in heat noises of the attenuator 13, thereby setting the S/N of the carrier at an output 17.
