Abstract: A non-contact power feeding device feeds power from a power transmission coil to a power receiving coil based on a mutual induction effect of electromagnetic induction. In such a non-contact power feeding device, power can be fed to the power receiving coil by a mobile power feeding method whereby the power receiving coil is moved corresponding to the stationary power transmission coil through an air gap in the case of power feeding. The power transmission coil and the power receiving coil are respectively formed in a loop-shaped flat structure. A crossover coil is adopted to serve as the power transmission coil. The crossover coil is formed in a long loop shape along the direction of movement of the power receiving side and is crossed along the way to provide a plurality of units. It is however to be noted that a resonant repeating coil can be used together with the power transmission coil to adopt the crossover coil as its repeating coil.

Abstract: A high frequency electric wire is provided in such a manner that a large number of wires are bundled, twisted and insulated with an outer sheath S. Each wire has an extra-fine hollow pipe structure of a capillary shape. The wire is provided to make its hollow section with the extra-fine hollow pipe structure an air cavity or to cause its hollow section to house an insulating material. In the latter case, the wire is provided by causing a metal conductor to adhere to the outer periphery of an extra-fine insulating yarn, which serves as the insulating material, by plating or vapor-deposition. The electric wire is used as a circuit cable or a coil in a non-contact power feeding device which supplies power based on a mutual induction action of the electromagnetic induction. In this manner, the electric wire fulfills its function to suppress and reduce an increase of the alternating current resistance due to a high frequency alternating current.

Abstract: An improved heat resisting structure for treating the exhaust gas of a gas engine is disclosed. The heat resisting structure has a honeycomb-form structure formed of corrugated and flat sheets which are alternately overlapped, rolled up, and joined via a brazing filler metal to make a roll-form structure. The brazing filler metal is made of iron(Fe)-base brazing filler metal, and the stainless steel corrugated sheet and flat sheet constituting the base metal are similar in composition. Accordingly, almost no difference exists in the coefficient of thermal expansion between the brazing filler metal and the base metal. As a result, cracks caused by thermal stress between them due to a difference in coefficient of thermal expansion is avoided even when used repeatedly.
