摘要： A tool for driving headed fasteners has an opening in the tool. The opening is defined by a wall of the tool. The wall has a plurality of flat planar surfaces. The planar surfaces are connected by a connection at the ends of each planar surface to define the opening. Each connection surface has a convex surface continuous with the planar surface. A concave surface is continuous with the convex surface. The convex and concave surfaces define arcs with the arcs having the same radius.

摘要： The preferred field assembly includes a field shell of generally T-shaped radial cross-section and molded of powdered metal, a plastic bobbin for supporting a multiple turn winding, and a plastic bobbin ring which covers part of the field shell and which helps hold the bobbin in assembled relation with the field shell. The bobbin is formed with a terminal block for supporting electrical leads which extend along grooves in the outboard face of one flange of the bobbin and which, together with the end portions of the winding, extend into potting cavities in the outboard face of the bobbin flange. The bobbin ring includes a cap which interfits with the terminal block to retain the leads. Various embodiments of field shells, bobbins and bobbin rings are disclosed.
