A short-circuiting member for preventing a commutator from being elongated in the axial direction without increasing the types of different components. The short-circuiting member includes components, each having outer and inner circumferences. Each component includes outer circumference terminals arranged along the outer circumference, inner circumference terminals arranged along the inner circumference, and connection portions connecting a corresponding one of the outer circumference terminals and a corresponding one of the inner circumference terminals that are separated from each other by a predetermined angle in a circumferential direction. The outer and inner circumference terminals are substantially formed along the same plane. The components are laminated in a state in which the connection portions of one of the components are reversed to the connection portions of another one of the components. The outer circumference terminals that are adjacent in a lamination direction are in contact with each other, the inner circumference terminals that are adjacent in the lamination direction are in contact with each other, and the connection portions that are adjacent in the lamination direction are not in contact with each other.

Coils are provided on a plurality of tooth sections of a core. The coils are formed by successively winding a conductor on the tooth sections with at least one tooth section between each successive windings, such that each portion of the conductor extending between two tooth sections located with at least one tooth section therebetween forms a jumper wire extending in the circumferential direction of the core. A commutator has a plurality of claw portions projecting to the outside of the commutator. Each of the claw portions electrically connects one of a plurality of segments to one of the jumper wires. When the core and the commutator are attached to a rotary shaft, each claw portion is arranged at a position corresponding to one of the jumper wires as viewed in the axial direction of the rotary shaft.

A process for the purification of an inert gas recycled from a polymerization reactor is disclosed, comprising the steps of mixing the gas with oxygen or gas containing oxygen in stoichiometric quantity or in such an excess that the gas at the outlet of the catalyst bed contains no more than 250 ppm of oxygen, circulating the gas through a catalyst bed comprising platinum, which has been subjected to a reducing environment, at temperatures of no more than 300° C. (572° F.) and preferably no more than 250° C. (482° F.) and recycling the gas to the polymerization reactor.

To provide a flat panel type color cathode ray tube which has a favorable feeling of flatness and can improve the drop strength of a shadow mask, a curvature along a diagonal direction of an outer surface of a panel 1 approximates to flat, an equivalent radius of curvature Rox along an X axis on the outer surface of the panel 1 is made smaller than an equivalent radius of curvature Roy along an Y axis on the outer surface of the panel 1 and an equivalent radius of curvature Rix along the X axis on an inner surface of the panel 1 is made larger than an equivalent radius of curvature Riy along the Y axis on the inner surface of the panel 1. Further, the optimum value of a ratio between the equivalent radius of curvature along the Y axis on the inner surface of the panel 1 and the equivalent radius of curvature along the X axis on the inner surface of the panel 1 is set to fall within the range of 0.7

A commutator main body 11 includes a plurality of commutator pieces 13 arranged along a circumference, the center of which is a rotation axis L of a motor, and a main body insulator 14 holding the commutator pieces. A short-circuit member 12 is arranged on an end portion of the commutator main body 11 and includes a short-circuit conductor 21, which short-circuits predetermined ones of the commutator pieces, and a short-circuit insulator 22, in which the short-circuit member is embedded. A boss is formed integrally with the short-circuit insulator so as to project from the end portion of the commutator main body.

A commutator includes a commutator body having segments and a short circuit member for short-circuiting the segments. The short circuit member includes first short circuit pieces and second short circuit pieces that are stacked. A radially outer end portion of each first short circuit piece is overlapped with and connected to a radially outer end portion of one of the second short circuit pieces. The short circuit member is arranged at an axial end of the commutator body such that each pair of the overlapped radially outer end portions corresponds to one of the segments. The radially outer end portions and the segments each have a connecting projection. The connecting projections of each pair of the overlapped radially outer end portions and the connecting projection of the corresponding segment are arranged to form an adjacently arranged set of the connecting projections, which are bonded by welding.
