A lighting apparatus includes a metal mounting fixed to a needed place such as a ceiling or a wall, rod-shaped holding metal fixtures, and a lighting apparatus body constituted by a chassis to which one end portion of each holding metal fixture is loosely fitted, a board which is fixed to the chassis and on which light emitting diodes are mounted as luminous elements, a reflecting panel, a cover (diffusing panel) that covers the light emitting diodes, and so on. By inserting the lock section of the other end portion of each holding metal fixture into an insertion hole and then locking each holding metal fixture on the metal mounting, the lighting apparatus body is held in a state of being separated from the metal mounting.

A pipe joint and a method of joining pipes using the pipe joint prevent loss of a sleeve, enhance workability in the pipe joining operation, and ensure sealing performance. The pipe joint may be utilized in a refrigerant device, a heat pump hot water supply device, a closing valve and a water supply piping. The method for connecting piping may be used in an in-the filed piping method. The pipe joint includes a joint body, a fastening member such as a nut, and a sleeve. The sleeve is integrated with the fastening member or the joint body before the fastening member is attached to the joint body. When the fastening member is attached to the joint body, the sleeve is cut off and separated from the fastening member or joint body. When the nut is fully attached, the sleeve bites into the pipe, and the pipe is joined to the joint body.

A core main body includes an outer peripheral iron core, and at least three iron cores. Between the two iron cores adjacent to each other, a gap being magnetically couplable is formed. The outer peripheral iron core includes a first outer peripheral iron core block and a second outer peripheral iron core block that are formed by stacking a plurality of magnetic plates, and an intermediate plate disposed therebetween. The intermediate plate includes an outer peripheral iron core corresponding portion corresponding to the outer peripheral iron core, a plurality of protruding sections protruding from an outer peripheral surface of the outer peripheral iron core, and engaging sections provided on the plurality of protruding sections.

A pipe joint includes a sleeve that is non-movably integrated with a nut prior to the nut being threadedly coupled to a joint body. The sleeve is separated from the nut by threadedly coupling the nut to the joint body prior to contact between the sleeve and a guide surface of the joint body so as to stabilize the separation timing of the sleeve from the nut and ensure the sealing property at portions where the sleeve bites. When the nut is further threaded to the joint body, a distal end portion of the sleeve is pressed by a guide surface formed on the joint body and deformed. As a guided surface is guided by the guide surface, the distal end portion bites into an outer peripheral surface of the pipe.
