Abstract: A stator iron core of an electric motor including plural magnetic pole segments. Each of the pole segments include a back yoke portion, a teeth portion projected from the back yoke portion, a connection portion provided to the back yoke portion for connecting adjacent magnetic pole segments, and a stepped-shaped notch on an outer circumference of the back yoke portion. Further, the stator iron core is circularly formed by bending the connection portions of the plural magnetic pole segments.

Abstract: A stator iron core of an electric motor including plural magnetic pole segments connected and confronted by plural confronting surfaces. Further, two of the confronting surfaces respectively include a V-shaped projection and a V-shaped recess.

Abstract: The present invention aims to provide a stator iron core of an electric motor which can eliminate the reduction of efficiency, vibration or noise of the electric motor by decreasing stress generated at a bottom portion of a slot on manufacturing or integrating the electric motor. Plural magnetic pole segments, each having a back yoke portion and a teeth portion projected from the back yoke portion, are connected so as to be bendable via a connection portion provided to the back yoke portion. After winding the coil wire, a stator iron core of the electric motor is circularly formed by bending the connection portion of the plural magnetic pole segments. In the stator iron core, the bottom portion of the slot constituted by the back yoke portion and the teeth portion is made to have a curved line after the stator iron core is circularly formed.

Abstract: Disclosed is a novel chlorine-free modified polyolefin composition with excellent adherence to polyolefin substrates, with excellent solventresistance, oil resistance and weather resistance, with no tack, and also with excellentcohesion, obtainable by using 0.5 to 15% (by weight) of maleic anhydride and 0.1 to 7.5% (by weight) of styrenic monomer to polypropylene, eyhylene-propylene copolymer or ethylene-propylene-buten copolymer, and by graft polymerizing so as the weight ratio of maleic anhydride to styrenic monomer to become not less than 2 to not more than 5.

Abstract: In a scroll compressor, a clearance is made between the opposed faces of a bed plate of a fixed scroll and a stationary member and a compression gas is introduced into the clearance for pressing the fixed scroll against an orbiting scroll. A recess is made in the center of the stationary member, is surrounded by a muffler, and is formed with a discharge hole directed in a radial direction. The scroll compressor can be assembled efficiently.
