摘要： PROBLEM TO BE SOLVED: To protect a connecting part without generating coming off by vertically installing a long belt formed by extending one contraposition part of a locking mechanism resisting against locking/unlocking energization in at least one portion of opening parts of a resin cap, and installing the other contraposition part of the locking mechanism in the opening part or side surface of the cap on the opposite side to the long belt vertically installed part. SOLUTION: A band 13a having plural holes 13a of a rectangular cross section is vertically installed in an opening part edge 12a of an insulating cap 12 whose head is hemispherical. A locking body 14 whose cross section is the same shape as the hole 13a and tip is formed in a wedge shape is installed an opening part edge 12b on the opposite side so as to project to the outside of the insulating cap 12. The specified amount of a sealing material such as epoxy resin is injected in the insulating cap 12, an electric wire terminal part is embedded, the band 13 is stretched to the locking body 14 side after being strided over a branched electric wire, and the hole 13a is pushed to the root of the locking body 14. Locking/unlocking of a connecting sleeve is manually allowable, but impossible by the locking/unlocking energized by hooking of the connecting part.

摘要： PROBLEM TO BE SOLVED: To improve the executability by connecting two groups of anode oxidizing metal bodies embedded in concrete with a direct current power supply device and oxidizing and inflating the metal body on positive pole side. SOLUTION: A backfill 11 and anode oxidizing metal bodies 5a, 5b such as iron, zinc, magnesium, aluminum, etc., are inserted into a hole 4 provided in concrete 2 to connect lead wires 3a, 3b mutually, and then an inlet is sealed by a sealing material 12. Next, the metal bodies 5a, 5b are connected with a positive pole and a negative pole of a direct current power supply device 6, respectively, to destruct the concrete 2 due to inflation pressure of an oxidized corroded product accumulated on a surface of the metal body 5a. Instead of this, the metal bodies 5a, 5b are magnesium, aluminum, zinc, etc., which cause alkali corrosion, the metal bodies 5a, 5b are corroded in oxidation corrosion and alkali atmosphere, respectively, and a corrosion product is accumulated on the surfaces of the metal bodies 5a, 5b to destruct the concrete 2. Consequently, a destruction rate can be controlled by a current carrying amount, and a structure can be destructed easily and safely.

摘要： PROBLEM TO BE SOLVED: To make it possible to simply and appropriately judge a normal/ defective condition of a connection between a DC power source device and a DC load circuit, a normal/defective condition of the DC power source device itself and whether or not there is any faulty in a display function part itself. SOLUTION: This device supplies a direct current to a DC load circuit 9 of an anode/electrolyte/cathode system. Hereby, a display body 4 has its pole connected between a secondary side of a transformer 2 or a positive electrode of a rectifier circuit 3 and a negative electrode of the DC load circuit 9, displays a condition in which an electric power is properly supplied to the DC load circuit 9 from the DC power source device 1, judges that some inconvenience occurs by an absence of display on the display body 4.

摘要： PROBLEM TO BE SOLVED: To eliminate a fishhook and a fishline hooking to the interior of the body of a fish and a bird to the exterior of the body in an early stage. SOLUTION: This fishhook 1 has at least a tip part from a barb 3, or at least the tip part from the barb 3 and an eye 5 composed of the most base metal or alloy in the fishhook 1 having plural metal surfaces having different standard electrode potentials in surroundings for use so that the contact corrosion between different metals may be caused between the tip part from the barb 3 and the eye 5 of the fishhook 1, and other parts, and the tip part from the barb 3 and the eye 5 of the fishhook 1 may eliminate in an early stage.

摘要： PROBLEM TO BE SOLVED: To manufacture a high-precision silver.silver chloride electrode by electrolytically oxidizing a silver substrate worked mechanically and polished chemically, in a solution containing chloride ions, and chloridizing the surface layer part of the silver substrate. SOLUTION: A silver substrate obtained by cutting a silver round bar of a diameter 10mm and a purity 99.9% into a length of 40mm for example, and degreasing, wet-polishing, and washing it, connecting a lead wire to its one side after that, and covering the periphery of the lead wire connected part with a thermally shrinking tube with an adhesive leaving a specified test surface as it is, and a silver plate as an electrode are prepared. This silver substrate with a lead wire is polished chemically by dissolving its surface, by dipping it in a mixed solution, in a agitated state, composed of 10% of saturated chromium oxide (valence VI) solution, 5% of hydrochloric acid, and the remaining of distilled water for about a minute. The silver substrate with a lead wire obtained by polishing and the silver plate are dipped in a 0.75N hydrochloric acid solution, and a current is caused to flow by a current density of 1.0mA/cm for about one hour with the silver substrate with a lead wire as an anode and with the silver plate as a cathode. Consequently, it becomes possible to manufacture silver-silver chloride electrodes having silver chloride layers on the surfaces of silver substrates with lead wires.
