Abstract: An ignition coaxial cable includes at least a braided layer of copper wires surrounding a central or inner conductor existing at a longitudinal center of the coaxial cable for shielding and grounding the interference caused by the high voltage carried by the cable, and an interference eliminating circuit having an inductor parallelly connected with a high-impedance resistor and connected in series with a low-impedance resistor to prevent the acute wave forms and to inhibit the surge waves caused by the high-tension voltage pulses delivered from the distributor to the plug, thereby eliminating the interference or electromagnetic interference caused by the high-tension cable and the plug of the car.

Abstract: An outdoor living apparatus includes: a shell having a mattress bag portion and a sleeping bag portion superimposed with each other; an inflatable mattress which may be normally embedded in the mattress bag portion of the shell to serve as a bed mattress adapted to be slept by a user sleeping in the sleeping bag portion superimposed on the mattress bag portion when the shell and the mattress are flattened, or may be removed from the mattress bag portion of the shell to serve as a swimming or beach mattress or as a life buoy in case of ship accidents; and a pair of convertible setting belts normally fastened to two opposite end portions of the shell to suspend the shell and the inflatable mattress filled in the shell between two fixtures or trees to be a hammock, or the two setting belts converted to be fastened to a right and a left side of a chair as folded from the hammock with flattened shell and mattress for seating purpose.
