摘要： A golf ball with three dimples (14) having the same shape and an equal diameter and an equal depth are distributed about the center of each spherical regular triangle (13) such that three line segments connecting the centers of the three dimples (14) define a regular triangle (15). The length of each line segment, that is, length (D.sub.D1) of one side of the regular triangle (15) does not exceed twice the diameter (D.sub.m) of the dimples (14). No other dimples are located within the regular triangle (15) associated with the three dimples (14). Two dimples (16) having the same diameter as the three dimples (14) are distributed on each side of the spherical regular triangle (13) in symmetry with respect to its middle point such that the distance (D.sub.D2) between the centers of the two dimples (16) does not exceed twice the diameter (D.sub.m) of the dimples (16).

摘要： A golf ball with improved flight distance is disclosed. The golf ball has at least three pluralities of dimples in its spherical surface. The dimples of each plurality share the same diameter and depth characteristics, such characteristics varying from the corresponding diameter and depth characteristics of the dimples of the other pluralities of dimples. However, the ratio of the diameter to depth of the dimples of a particular plurality of dimples approximates the ratio of the dimples in every other plurality of dimples such that the difference between the ratio of the dimple of one plurality of dimples and any other plurality of dimples is less than 0.3.

摘要： A golf ball having at least three types of dimples arranged in a specific distribution pattern has improved aerodynamic symmetry and offers consistent flying performance. Three phantom orthogonal great circles are drawn on the spherical surface of the ball to define eight spherical regular triangles, and phantom perpendiculars are extended from the three apexes of each spherical regular triangle to the opposite sides to divide the spherical regular triangle into six equal spherical right triangles, thereby dividing the entire spherical ball surfaces into 48 equal spherical right triangles.dimples are arranged on every two adjoining spherical right triangles such that the dimples are in axial symmetry with respect to the common side of the two adjoining spherical right triangles and the dimples do not intersect the great circles.

摘要： An iron-type golf club head has a face which has a face surface of a flat shape, and a hosel which is continuous with the face on its heel side. A shaft insertion hole is disposed in the hosel. A protrusion protruding rearward is disposed in the vicinity of the center in a toe-heel direction. A material of the golf club head is pure iron having a high purity of at least 99.8%, for instance, pure iron having a purity within a range of 99.995 to 99.9999%. The golf club head is subjected to carburizing so that carbon diffuses up to about 0.2 to 0.5 mm from the surface. A region within 0.2 mm from the face surface has a hardness of HV 300 to 600, and a region where a distance from the face surface is 0.7 mm or more has a hardness of HV 100 or lower.
