摘要： PROBLEM TO BE SOLVED: To select and connect a pair of lead wires to a distortion-measuring apparatus thereby forming an electric circuit at an optional point, by connecting a plurality of insulated coated lead wires via a suitable interval to a long insulated coated resistance wire. SOLUTION: A distortion sensor 1 has lead wires 3 connected via a suitable interval to a thin long resistance wire 2, and is coated with a coating 4. The resistance wire 2 used a thin wire so that it can be positioned between a concrete structure and a reinforcing layer or between reinforcing layers. The connection of the lead wires 3 to the resistance wire 2 is made by soldering or spot welding so as not to increase an outer diameter of the distortion sensor 1. The resistance wire 2 is formed of a conductive material that can act integrally with a place where the wire is placed, e.g. an advance wire of an alloy of nickel, cobalt, copper and manganese.

摘要： PURPOSE:To obtain a non-directional or nearly non-directional light using a light emitting diode by radiating the light from a light source on a reflecting mirror, and irregularly reflecting the reflected light on the inner surface of an outer casing having the inner surface as an irregularly reflecting surface of light. CONSTITUTION:Light emitting diodes 2 are disposed on the both surfaces of a printed board 3 and situated in the middle of a translucent outer casing 1. The outer casing 1 is formed in a cylindrical form and subjected to diamond cut processing so that the inner surface irregularly reflects light. When an electric current is applied to make the light emitting diodes 2 luminous, the emitted lights are reflected by a reflecting mirror 5, and repeatedly irregularly reflected by the irregularly reflecting surface of the inner surface of the casing 1 to make the whole wall surface of the outer casing 1 luminous.

摘要： PROBLEM TO BE SOLVED: To solve the problems such that it is difficult for a concrete structure in a workability to lay an optical fiber cable and that when laying the cable on a surface of the structure, beauties of the structure are damaged due to cutting the surface of the structure. SOLUTION: In a facial distortion sensor for verification of damage proceeding of concrete structure, single or more than one optical fiber cable is fixed with pulling one end of the cable to be inserted between a gap of sheet shaped objects allowing penetration of an adhesive. In a method for verification of damage proceeding of concrete structure, the sensor is bonded on the surface of the structure by using the adhesive to verify the damage proceeding with measuring distortion by using one end of the cable pulled from the gap of the objects.

摘要： PROBLEM TO BE SOLVED: To prevent the coming-off and deformation of an adhesive while or after a cored laminated fiber-reinforced plastic sample is pushed in a drill through a cored hole at the time of cutting-off the sample by using a coring blade attached to the front end of the drill. SOLUTION: A cylindrical drill section 2 in which a pressure bar spring 5 both ends of which are respectively attached to a spring pressure adjusting screw 5 and a presser bar 9 is set so that the spring pressure of the spring 5 may be adjusted by means of the screw 7 is connected to a cylindrical drill section 3 provided with a cylindrical coring blade 12 at its front end by engaging the thread of the section 2 with the thread of the section 2 and the presser bar 9 attached to the spring 5 is inserted into the coring hole 17 of the blade 12. Since the laminated sample of a fiber-reinforced plastic 23 is pressed by the presser bar 9, the occurrence of such a case that the sample 24 is pushed in the drill section 3 or an adhesive comes off or is deformed can be eliminated when the laminated sample 24 is collected.

摘要： PURPOSE:To obtain a light emitting lamp illuminated on the whole outer cylinder by arranging light sources made of light emitting diodes in the translucent outer cylinder and arranging reflecting mirrors with irregular reflection mirror faces facing the light sources. CONSTITUTION:An outer cylinder 1 is formed with a transparent acrylic tubular material, it is diamond-cut-machined on the inner face so that light is irregularly reflected, diodes 2 are arranged to have directivity in the end section direction of the outer cylinder 1 when arranged in the outer cylinders 1. Reflecting mirrors 5 are formed as irregular reflection faces of light with the mirror faces diamond-cut, they are coupled and fixed inside rubber caps 4. When light emitting diodes 2 are illuminated, light is radiated to the reflecting mirrors 5 with some width, the radiated light is irregularly reflected in response to the incidence angle of the irregular reflection face and irregularly reflected on the inner face of the outer cylinder 1, the irregular reflection is repeated. The whole outer cylinder is thereby illuminated.

摘要： PROBLEM TO BE SOLVED: To non-destructively recognize the number of stacked layers without damaging an adhesive layer by permitting an induction magnetic field-type sensor to participate in the surface of the adhesive layer where fiber cloth to which the thin wire of a magnetic body is filled at an appropriate interval is stacked. SOLUTION: The adhesive of epoxy resin is impregnated or applied to fiber cloth 1 to which thin wires 2 are filled. Only an n-layer is stacked in concrete structure and a reinforcing layer is formed. At that time, the thin wires 2 of the respective layers in fiber cloth 1 are stacked by shifting them at an interval of (a). The wheels 33 of a search part 3 and a supporting roller 34 are closely stuck to the surface of the adhesion layer where fiber cloth 1 is stacked and scanning is executed. The recording paper 6 of a recording part 4 is transmitted by length proportional to a scanning distance. When the guidance magnetic field-type sensor 32 senses the thin wires in the process of scanning, recording paper 6 is transmitted. Since the difference of the width of a pulse exists between a surface layer close to the thin wire 2 and an inner layer far from it, the induction magnetic field-type sensor 32 can discriminate a depth direction and can recognize the number of the layers of fiber cloth.

(A) Lateral auxiliary yarn groups are placed on both the sides of a reinforcing multi-filament yarn sheet obtained by arranging reinforcing multi-filament yarns not having such a curve as concentrating stresses into a sheet-like shape in one direction and in parallel to each other, and the lateral auxiliary yarn groups form a woven tissue together with longitudinal auxiliary yarn groups parallel to the arranged reinforcing multi-filament yarns to integrally hold the yarn groups. (B) The adjacent reinforcing multi-filament yarns have spaces of 0.3-2 mm therebetween. (C) Metal wires are inserted.

摘要： PROBLEM TO BE SOLVED: To permit the verification of the development of damage in a concrete structure over a wide range, by laying a mesh-shape distortion sensor formed of one continuous optical fiber cable between the concrete structure and a reinforcing material. SOLUTION: One optical fiber cable 2 is bent by predetermined widths and bending intervals and is knitted with fixing warps 3 to form a mesh-shaped distortion sensor. After placing the distortion sensor on the lower surface of a concrete floor plate 10, a reinforcement material steel plate 11 is installed to the concrete floor plate 10 at a predetermined space interval. Then an adhesive is injected into the space to adhere the concrete floor plate 10 integrally to the steel plate 11. Next, a connector 4 is installed to one end of the optical fiber cable 2 derived from between the concrete floor plate 10 and the steel plate 11 and is housed in a housing box 13. At the time of measuring the state of development of damage in the concrete structure, a distortion measuring device 15 is connected to the connector 4 via a lead wire 14 to measure the distribution of distortion.
