发明名称 New nonaqueous electrolyte for improved performance and stability
摘要 <p>A game ball racket with a reverse sunburst string pattern comprising a frame shaped to have its free ends extend parallel to form a handle, with its central extent in a general loop shaped configuration to constitute a head, the frame has an axis centrally disposed through the center of the handle and head, the head is formed with a plurality of spaced apertures extending through its periphery. A first string is positioned through first selected apertures in the head to form cross strings perpendicular to the axis and parallel with each other, the cross strings are spaced from adjacent cross strings a distance greater at the end adjacent the handle than at the opposite end with such spacing decreasing in such direction. A second string is threaded through second selected apertures in the head to form main strings nearly parallel to, but offset from, the axis, each main string is positioned at a small angle with respect to the axis and with the main strings further remote from the center line being at a greater angle than the angle of the strings adjacent to the axis with the angle between adjacent strings increasing with the distance away from the axis, the main strings are spaced more widely apart adjacent to the handle than at the end remote therefrom, the main strings and cross strings constituting a planar string bed.</p>
