Title: Monitor system and loopback circuit used for it
Inventor: NOMURA KENICHI
IPC: H04B10/43
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To accurately monitor a repeater by decreasing the number of outgoing and incoming signal wavelength bands in monitoring the wavelength multiplex system. SOLUTION: The system monitors terminal stations 1, 2 sending and receiving an optical signal, an optical fiber for incoming and outgoing channels to send this optical signal, and pluralities of digital 2-way relay transmission channels that directly amplify and send the optical signal attenuated through the optical fiber. Each of repeaters REP1-REP3 has an optical amplifier for each transmission channel, a photocoupler coupled with an output of the optical amplifier and separating the output into two optical fibers, an optical filter that extracts a monitor wavelength signal from the output of the photocoupler and outputs it to an opposite transmission channel.  When the optical pulse signal with a monitor wavelength is sent to the optical fiber from one terminal station, a faulty repeater is evaluated based on an amplitude of each pulse in a pulse train reflected to the terminal station in a propagation time corresponding to a distance from the terminal station to each of the repeaters REP1-REP3.

IPC: G01N29/04
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To nondestructively detect ruptured parts in steel skeletons covered with fireproof coatings only by partially removing a fireproof coating. SOLUTION: Fireproof coatings on the surface of a steel skeleton at distances L1 and L2 from reference points A1 and A2 , which are predicted ruptured parts of a steel structure covered with fireproof coatings, are exfoliated all over the width to form measurement planes 25. Probes 15 are pressed against the measurement planes 25, and surface SH waves are transmitted toward the predicted ruptured parts. Reflected waves received at the measurement planes 15 are transferred from a flaw detector 20 to a PC 21. A transferred check waveform 22 is compared with typical ultrasonic waveforms (experiment values) 23a and 23b at the PC 21. The presence of ruptured parts is determined in the case that the check waveform 22 match a waveform 23b, and the absence of ruptured parts is determined in the case that the check waveform 22 match a waveform 23a.
