Filed: 1995-04-12
Abstract: PURPOSE: To obtain an equipment for carrying out external hydraulic test of a flexible synthetic resin tube under a state similar to the state applied with earth pressure by fixing the recessed outer circumferential surface of the resin tube closely to the recessed upper inner wall face of a container body. CONSTITUTION: A flexible synthetic resin tube 2 fixed, at the opposite ends thereof, with synthetic resin tubes 5 is contained in a container body 1. When the fixed end part 3 inserted with the resin tube 5 and each flange at the end 12 of the container body are secured hermetically, the recessed outer circumferential surface 21 of the flexible tube 2 being bent are fixed closely to the recessed inner wall face 13 of the body 1. It is the fixed to an external hydraulic pressure test equipment and an air vent valve 7 is opened by injecting 6 water. After the body 1 is filled with water, the valve 7 is closed and external hydraulic pressure test is carried out while applying a predetermined hydraulic pressure.  The flexible tube 2 begins to deform hydraulically but since the outer circumferential surface 21 is fixed closely to the inner wall face 13, the deformation is blocked and the external hydraulic pressure test is carried out while sustaining a predetermined radius of curvature. Consequently, the test can be carried out under a state similar to the state where the flexible tube 2 is buried in the earth while being bent and applied with earth pressure.

Abstract: PROBLEM TO BE SOLVED: To enable an element to separately fetch the corresponding electric signals by itself by processing two kinds of light rays having different wavelengths. SOLUTION: A two-wavelength end face light receiving photodiode is constituted by forming a photodiode which has a P-type diffusion region 10 and processes first light (λ1) in one half section of a laminated body and another photodiode having a fourth layer LA4 which is formed between light waveguide layers LA3 and LA5 and absorbs second light (λ2) in the other half section. The light L2 (λ2) made incident through the end face of the element is absorbed by the light absorbing layer LA4 and photoelectrically converted and, as a result, a signal voltage V2 is obtained. The light L1 (λ1) which is made incident through the same end face is not absorbed by the layer LA4, but is made to pass through the light waveguide layers LA3 and LA5 and reflected by a reflecting layer 22 on the rear side.  The reflected light reaches the diffusion region 10, is absorbed by an absorbing layer LA1 which absorbs the light L1, and is photoelectrically converted. As a result, another signal voltage V1 is obtained.

Title: Coiling machine of tube and method thereof
Inventor: SAITO MASAHIKO
IPC: B66D1/36
Filed: 1995-04-13
Abstract: PURPOSE: To quickly execute speed control by detecting tube locus with a tube locus detector arranged between a preliminary tube bending machine and coiling drum and inputting the signal to a tube feeding speed control device. CONSTITUTION: A tube 1 is fed in a coiling drum at a prescribed speed with a feed roll 21 of a tube feed mechanism 2. The tube is bent by a tube preliminary bending mechanism 3 beforehand so as to coincide with the curvature of drum 4. A tube locus detector 7 is arranged at the part between the tube preliminary bending mechanism and coiling drum 4, at which the tube 1 passes. The tube locus detector 7 pinches the tube 1 with guide rolls 71, 72 and detects the passing position of tube 1. A speed controller 6 receives the detected value of tube locus detector 7, compares with the reference value of ideal locus and controls the speed of feed roll 21. Because the tube 1 is corrected to ideal locus before coiling to the coiling drum 4, the collapse of tube 1 due to abrupt bending is prevented.
