摘要： A solid golf ball is composed of a solid core and a cover of one or more layers which encloses the core and has on a surface thereof numerous dimples. The solid core has a diameter of 38.7 to 39.6 mm and a deflection hardness of 3.0 to 4.0 mm. The cover has a Shore D hardness of 59 to 70 and has 313 to 371 dimples formed thereon. The ball has an initial velocity of at least 76.8 m/s, a coefficient of lift (CL) when hit of at least 0.165 at a Reynolds number of 70,000 and a spin rate of 2,000 rpm, and a coefficient of drag (CD) when hit of not more than 0.230 at a Reynolds number of 180,000 and a spin rate of 2,520 rpm. The golf ball has a carry which is long enough to make the ball advantageous for competitive play, in addition to which it has a good feel when hit and excellent durability to cracking with repeated impact.

摘要： In a golf ball composed of a resilient solid core and a resin cover which encloses the core and has on an outside surface thereof numerous circular dimples, the cover has a maximum thickness of 0.5 to 1.5 mm and is made of a polyurethane elastomer having a Shore D hardness of 40 to 58; the total number of dimples on the cover is from 390 to 420, of which 40 to 80 are small-diameter dimples with a diameter of 2.0 to 2.7 mm; and the dimples are arranged so that total planar surfaces circumscribed by dimple edges which delineate boundaries between individual dimples and surrounding land areas that form an outermost surface of the ball account for 74 to 84% to an imaginary sphere defined by the surface of the ball having no dimples thereon. The golf ball of the invention does not readily lose lift even near the highest point in the trajectory of the ball when it has been hit, and thus can beneficially increase the distance of travel.

摘要： A golf ball with a number of dimples within a pair of spherical isosceles triangle regions formed by imaginary lines connecting one pole and the equator. The dimples in the triangle regions are arranged in a position rotationally moved about the ball axis from a position in axial symmetry with respect to the imaginary line. The dimples on the other hemisphere are in point symmetry with the dimples as arranged on the one hemisphere with respect to the ball center.

摘要： A golf ball having a plurality of dimples demarcated by edges on the ball's surface, characterized in that the dimples each assume a non-circular shape (as viewed form above) with mutually intersecting curved edge elements of the edges and at least one of these non-circular dimples is demarcated by the edge whose edge element bulges toward the inside of the dimple. The golf ball has improved aerodynamic performance due to dimples and achieves a long flying distance.
