An armature coil for a rotary electric machinery includes a plurality of identical coil blocks each formed by a plurality of turns of and elongated conductor. Each of the coil blocks includes two groups of axial sections which are diametrically opposed to each other, and curved sections joining the two groups to each other at each axial end. The axial sections of one of the groups is disposed in an inner cylindrical layer while the axial sections of the other of the groups are disposed in an outer cylindrical layer which is coaxial with the inner cylindrical layer. The coil blocks are combined with each other by circumferentially shifting one coil block from another in such a maimer that the axial sections are arranged circumferentially along the inner and outer cylindrical layers, one next to another.

In an article, a binding layer formed through a heating step exists between a permanent magnet and a laminate of steel plates. The binding layer is formed by producing a liquid phase at the heating step from a brazing filler metal made of a rare earth element-based alloy. Diffusion areas exist between a body portion of the permanent magnet and a body portion of the binding layer and between a body portion of the laminate and the body portion of the binding layer, respectively. The thickness t of each of the diffusion areas is in a range of t&gE;5 &mgr;m. The bond strength in the article is greatly increased by the provision of the diffusion areas.

In producing a rotor for a rotating machine by bonding a rotor body and a plurality of permanent magnets to each other through a heating step and a subsequent cooling step, a rotor body having a larger coefficicient of linear thermal expansion at the cooling step has its joint surface formed by assembling of a plurality of small joint faces. Thus, it is possible to moderate a thermal stress in a brazing filler metal layer between the rotor body and each of the permanent magnets to avoid the generation of cracks in the permanent magnets having a smaller coefficient of linear thermal expansion at the cooling step and to firmly bond the rotor body and each of the permanent magnets to each other.

In an article, a binding layer formed through a heating step exists between a permanent magnet and a laminate of steel plates. The binding layer is formed by producing a liquid phase at the heating step from a brazing filler metal made of a rare earth element-based alloy. Diffusion areas exist between a body portion of the permanent magnet and a body portion of the binding layer and between a body portion of the laminate and the body portion of the binding layer, respectively. The thickness t of each of the diffusion areas is in a range of t.gtoreq.5 .mu.m. The bond strength in the article is greatly increased by the provision of the diffusion areas.

A permanent magnet material having as main components thereof a rare earth element, a transition element (except for rare earth elements and Cu and Ag), and nitrogen and containing as an additive component thereof at least one element selected from the group consisting of Cu, Ag, Al, Ga, Zn, Sn, In, Bi, and Pb. It finds extensive utility in magnetic recording materials such as magnetic tapes, magnetic recording devices, and motors, for example.

Permanent magnet material

A mechanical quantity sensor element making use of a stress-magneto effect of noncrystalline magnetic alloy. This mechanical quantity sensor element is manufactured by coupling a piece of noncrystalline magnetic alloy having positive magnetostriction with another material such as, for example, thermo-setting resin at a temperature exceeding an operating temperature range of the mechanical quantity sensor element, and then cooling them to the operating temperature range. Due to a difference in a coefficient of thermal expansion between the piece and the material, compression strain is preliminarily given to the noncrystalline magnetic alloy piece, and the mechanical quantity sensor element has an excellent linearity and a wide detectable range for mechanical quantities.

A mechanical quantity sensor element making use of stress-magneto effect of noncrystalline magnetic alloy. Compression strain is preliminarily given to a thin belt made of noncrystalline magnetic alloy by carrying out treatment of applying an external force onto a surface of the thin belt. Suitable methods for applying the external force include; surface grinding by means of abrasive cloth or paper, shot-peening in which spherical fine grains are impinged onto a surface of a thin belt, stroking work in which a surface of a thin belt is scrubbed by means of a scrubber piece made of synthetic resin, rubber or other material, and the like.
