Abstract
Official abstract text for this publication.
A golf ball 2 has, on a surface thereof, a plurality of types of dimples 8 having different diameters from each other. A standard deviation Vσ of the volumes of all the dimples 8 is equal to or less than 0.095 mm 3 . The ratio (Vσ/Dσ) of the standard deviation Vσ to a standard deviation Dσ of the diameters of all the dimples 8 is equal to or less than 0.35. Preferably, the shape of each dimple 8 is a portion of a spherical surface. The standard deviation Vσ is preferably equal to or less than 0.087 mm 3 . The ratio (Vσ/Dσ) is preferably equal to or less than 0.29.
First claim
Opening claim text (preview).
What is claimed is: 1. A golf ball having, on a surface thereof, a plurality of types of dimples, each of the types having different diameters from the other types, wherein a total volume of all said dimples ranges from 280 mm 3 to 340 mm 3 , a standard deviation Vσ of volumes of all the dimples is equal to or less than 0.095 mm 3 , a depth of each dimple ranges from 0.07 mm to 0.22 mm, a ratio (Vσ/Dσ) of the standard deviation Vσ to a standard deviation Dσ of diameters of all the dimples is equal to or less than 0.35, a total number of the dimples ranges from 270 to 350, and a ratio of a sum of areas of all the dimples to a surface area of a phantom sphere of the golf ball is equal to or greater than 75% but equal to or less than 95%. 2. The golf ball according to claim 1 , wherein a shape of each dimple is a portion of a spherical surface. 3. The golf ball according to claim 1 , wherein the standard deviation Vσ is equal to or less than 0.087 mm 3 . 4. The golf ball according to claim 1 , wherein the ratio (Vσ/Dσ) is equal to or less than 0.29. 5. The golf ball according to claim 1 , wherein the sum of the volumes of all the dimples is equal to or greater than 280 mm 3 but equal to or less than 330 mm 3 . 6. The golf ball according to claim 1 , wherein the ratio of the areas of all the dimples is equal to or greater than 80% but equal to or less than 95%. 7. The golf ball according to claim 1 , wherein a number of types of the dimples is equal to or greater than 4.
