Abstract: A refrigeration cycle comprises a compressor, an indoor heat exchanger, an outdoor heat exchanger, a liquid receiver; and a pressure reducer connected in series to form a closed loop. The liquid receiver and the pressure reducer connected in series are connected between the indoor heat exchanger and said outdoor heat exchanger. A non-azeotropic mixture refrigerant comprising at least two kinds of refrigerant of different boiling temperatures mixed together is charged in and circulated through the refrigeration cycle. The mixing ratio of the azeotropic mixture refrigerant circulated thorough the refrigeration cycle is controlled substantially constant.

Abstract: A method for assembling a motor vehicle body by fixing relative positional relationship among a plurality of motor vehicle body constituent parts by means of positioning members provided in a welding jig which is disposed on each side of an assembly station and, in this condition, welding together the plurality of motor vehicle body constituent parts at a plurality of tack-welding locations. First welding guns of indirect feeding type are mounted on the welding jig to weld a part of the tack-welding portions. A welding robot having mounted thereon a second welding gun is disposed outside the welding jig. The above-described part of the tack-welding portions are welded by supplying electric power from the second welding gun to the first welding guns by pinching, by the second welding gun, feeder terminals of the first welding guns in a condition in which the above-described part of the tack-welding portions are being pinched by the first welding guns.

Abstract: In an electric apparatus such as an electric power cable system, a high frequency pulse is induced on a conductive member such as a metal sheath, where partial discharge occurs in an insulation. The high frequency pulse is detected by means of a bypass lead wire, a metal foil electrode, a detecting coil, and the like provided on the electric apparatus without interrupting a live operation of the electric apparatus.

Abstract: The present invention provides a cationically polymerizable organic material composition comprising a composition which contains a cationic polymerization catalyst(s) and a cationically polymerizable organic material(s) as essencial ingredients, and one or more onium salts having a nucleophilic pair anion represented by halogenide, alkyl sulfate or p-toluenesulfonate ions, or one or more iron aromatic compound salts represented by the following formula (I): ##STR1## The composition of the present invention is a cationically polymerizable organic material composition capable of being cured by irradiation of a radiation or by heat, and it also has excellent storage stability at room temperature in the dark and a long pot life.
