1. A pet toy consisting of:
(a) an inner flexible elastomer ball having an inner ball wall,
(b) a squeaker mounted in the inner ball wall,
(c) an outer flexible elastomer ball having an outer ball wall, said squeaker being separate from the outer wall,
(d) an air hole mounted in the outer ball wall, and
(e) the inner ball being entirely within the outer ball and free-floating within the outer ball.
2. A pet toy as recited in claim 1, wherein the outer ball wall has an outer surface and the said outer surface is textured.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A method of forming a stator winding of a rotary machine, the method comprising steps of:
inserting U-shaped conductor segments into slots of a stator core so that segment ends of the U-shaped conductor segments extend from an axial end of the stator core;
arranging the segment ends so that pairs of segment ends, each pair to be electrically connected, are aligned along two or more coaxial circumferences, the pairs of segment ends aligned along one of the coaxial circumferences being positioned in a zigzag manner in a radial direction with respect to the pairs of segment ends aligned along other coaxial circumferences;
restricting a position of each pair of segment ends to establish a close contact between segment ends belonging to each pair by pressing individually each pair of segment ends from its outside with an outside restricting member and from its inside with an inside restricting member; and
electrically connecting segment ends belonging to each pair of segment ends by welding the segment ends by a welding apparatus.
2. The method of forming a stator winding as in claim 1, wherein:
the restricting step further includes a step of inserting a space-keeping member between neighboring pairs of segment ends aligned along the coaxial circumference to keep a predetermined space in a circumferential direction between the neighboring pairs of segment ends.
3. The method of forming a stator winding as in claim 2, wherein:
a portion of the space-keeping member is formed integrally with the outside restricting member and the other portion of the space-keeping member is formed integrally with the inside restricting member.
4. The method of forming a stator winding as in claim 1, wherein the electrically connecting step includes steps of:
activating the welding apparatus; and
causing relative movement between a welding electrode of the welding apparatus and the pairs of segment ends aligned along the circumference, while keeping a predetermined distance between the welding electrode and the pairs of segment ends and maintaining the welding apparatus activated, so that the pairs of segment ends are continuously welded one by one.
