Title: Detection of separation of lining of pipe
Inventor: HASEGAWA TATSUO
IPC: G01N23/04
Filed: 1983-06-10
Abstract: PURPOSE:To make it possible to accurately detect whether or not a lining of a pipe has separated, from the outside of the pipe, by carrying out a radiographic examination. CONSTITUTION:A metal piece 5 is previously buried between polyethylene lining members 3 and 4 of a pipe 2. Radiant rays are applied to the metal piece 5 from a radiation source 6 provided outside the pipe 2 to carry out a radiographic examination. A comparison is made between the image formed on a film 7 by photographing at the time of burying the metal piece 5 and the image on the film 7 formed by photographing at the time of the lining separation inspection. As the result of the comparison, even when the shadow of the metal piece 5 is on the image frame of the film 7 at the time of the inspection, if the shadow has changed, it is possible to estimate the fact that the lining members 3, 4 have separated from the inner surface of the pipe 2. On the other hand, when no shadow of the metal piece 5 is on the image frame of the film 7 at the time of the inspection, it is clear that the lining members 3, 4 have already flown out with the stream of the sea water 1.

Abstract: PURPOSE:To improve the SN ratio, by storing the signal charge given from a photodetecting element to the diffusion capacity of a diode provided to a semiconductor substrate and then transferring and reading the signal by means of a charge transfer element provided to said semiconductor substrate. CONSTITUTION:When light is irradiated to a photoelectric transducer 1, an optical current IP flows to a constant current source 18 corresponding to the element 1 in the direction of an arrow. Then the signal charge is stored in a capacity 19 of a diode 20 consisting of a p type semiconductor substrate 12 and an n type impurity diffusion layer 13. The anode of the diode 20 is connected to the negative potential of a bias power supply 10, and therefore the signal charge can be thoroughly stored in the capacity 19. Then a transfer gate 15 is turned on to transfer the signal charge stored in the capacity 19 to a capacity 21 formed under a transfer electrode 16 of a charge transfer element 17. The charge transferred to the capacity 21 is then transferred by a transfer pulse which is applied to the electrode 16. In such a way, the electric charge given from the gate 15 is stored temporarily in the capacity 21. This suppresses the generation of spike noises which is due to ON/OFF of the gate 15.
