摘要： PROBLEM TO BE SOLVED: To provide a brazing method capable of minimizing a shearing stress caused in a brazing filler metal layer after cooling, in brazing two planar bodies having a different thermal expansion coefficient. SOLUTION: Two planar bodies 3, 8 having a different coefficient are laminated through a molten filter metal layer, which is then solidified to braze the planar bodies together; in this case, the filter metal between the planar bodies is solidified with at least one of the two operations added, one of which is to temporarily reduce the brazing area of the planar body 3 having a larger thermal expansion coefficient, and the other of which is to temporarily enlarge that of the planar body 8 having a smaller coefficient; consequently, a shearing stress is minimized that is caused in the filler metal layer after cooling on account of the difference between the thermal expansion coefficients of the two planar bodies 3, 8.

摘要： PROBLEM TO BE SOLVED: To realize a fiber-optic sensor which detects local fluctuations of a site in which the sensor is buried. SOLUTION: The fiber-optic sensor 50 comprises an optical fiber 10 for observing environmental condition fluctuations and a support 51 which supports the optical fiber 10 along the longitudinal direction. The sensor 50 is provided with a sensing section 43, which is a measuring range between two points arranged spaced apart along the longitudinal direction of the optical fiber 10. In the sensing section 43, the optical fiber 10 is supported by the support 51 through the two points as fulcrums 42 to allow the section to be deformed with having a curvature. The fiber-optic sensor 50 buried in soil 44 in particular detects the fluctuations toward the convex side of the curvature with high sensitivity, even when the local fluctuations do not deform the support 51.

摘要： PROBLEM TO BE SOLVED: To manufacture an interior resin lining tube of a thick film at a low cost by lining a base tube such as a steel tube with a resin tube such as a conventional polyethylene tube which is almost free from the property of the diameter being expanded by heating.
SOLUTION: The resin tube to be applied as a lining to the base tube is drawn in the direction of the axis of the tube and thereby the diameter thereof is reduced to a dimension enabling insertion thereof into the base tube. In this state, the resin tube is cooled to a temperature of the freezing point of below to be frozen in the state of the diameter being reduced and also to be made the resin tube of which the diameter is reduced temporarily and of which the rigidity is enhanced. The operation of insertion is facilitated by inserting this resin tube into the base tube. The resin tube is restored to a state wherein the diameter is expanded and brought into closed contact with the inside of the base tube, by making it pass an appropriate time, and thus the tube is made an interior resin lining layer.

摘要： PROBLEM TO BE SOLVED: To form a corrosion-resistant coating having the non-hydrophilic characteristic of a non-polar resin coating regardless of the shape of a metallic material or the like by forming a corrosion-resistant layer of a reaction-curable resin on the surface of the metallic material and a non-hydrophilic treated coating film of a non-polar resin formed on the corrosion-resistant layer by fusion-bonding or adhesion. SOLUTION: The resin coating 1 is for resisting the corrosion of a metallic material 4 and has a thick film corrosion-resistant coating layer 2 of a reaction curable resin formed on the surface of the metallic material 4 by adhesion and a thin non-hydrophilic treated coating film 3 of a non-polar resin formed on the surface of the corrosion- resistant coating layer 2 by welding or adhesion. Thus the reaction curable resin of an epoxy resin to be used for the corrosion-resistant coating layer 2 proves to be corrosion-resistant for a long time by applying the resin in the form of a thick film. In addition, it is possible to easily form a thick film coating on a metallic material of a non-simple shape and a non-movable metallic material. Further, various issues such as the deposition of shells can be solved by forming the non-hydrophilic treated coating film 3 of the non-polar resin on the reaction curable resin coating.

摘要： PROBLEM TO BE SOLVED: To tear off a resin coating on an inner surface even from a metallic tube of such a small diameter as can not access an inner surface of the metallic tube. SOLUTION: In this method, a grip margin 2a is prepared by tearing off a resin coating 2 at one end of a metallic tube 1, and the grip margin 2a is connected to a holding and drawing means 4 inserted into the metallic tube 1. Then, the grip margin 2a is reversed. A tube body near a peeling front line 6 is heated by a locally heating means 5 so that an adhesion strength is temporarily decreased. While a heating position is successively transferred by moving successively the locally heating means 5 in a pipe axis direction, the holding and drawing means 4 is extracted toward the other end of the metallic tube 1, and the resin coating 2 can be torn off while it is reversed.
