  • Patent number: 8657705
    Abstract: A golf ball 2 has a large number of dimples 8 and a land 10. A rugged pattern is formed on the surface of the golf ball 2 by these dimples 8 and the land 10. These dimples 8 are arranged in a random manner. Each dimple 8 has a crater shape. For designing the rugged pattern, a Cellular Automaton method is used. A fluctuation range Rh of the golf ball 2 that is an index indicating the aerodynamic characteristic during PH rotation is 1.9 mm or less. A fluctuation range Ro of the golf ball 2 that is an index indicating the aerodynamic characteristic during POP rotation is 1.9 mm or less. The absolute value of the difference dR between the fluctuation range Ro and the fluctuation range Rh is 0.4 mm or less.

    Abstract: Generally disclosed is a golf ball having a core and a cover layer. The cover layer includes areas that are hard corresponding to the dimples, and areas that are soft corresponding to the land between the dimples. The cover layer may be selectively treated, such as by heating, to achieve a difference in hardness using a single cover layer material. Alternatively, the cover layer may be selectively coated with a coating material having a different hardness. As a result of the arrangement of the hard dimples and the soft land, the golf ball achieves reduced spin, and greater distances, when struck with a larger force (such as during a dive) while also achieving increased spin, and better control, when struck with a smaller force (such as during a chip).

  • Patent number: 8529375
    Abstract: Generally disclosed is a golf ball having a core and a cover layer. The cover layer includes a coating material thereon that increases the golf ball's moment of inertia. The coating material is coated on the cover layer in a pattern corresponding to one of the dimple pattern and the pattern of land areas separating the dimples. The golf ball's moment of inertia is increased while utilizing only a small amount of the coating material as a result of the pattern of coating material, which locates the coating material at an outermost radial distance from the golf ball's center of rotation (i.e., the golf ball's center of gravity). The increased moment of inertia causes the golf ball to have a lower rate of spin when hit by a golf club, thereby displaying different play characteristics.

  • Patent number: 8524852
    Abstract: Golf balls containing at least one layer made from a thermoset polyurethane or polyurethane-urea that is the reaction product of a polyisocyanate with moisture-resistant polyol and a curing agent are provided. The moisture-resistant polyol may be prepared by dimerizing unsaturated aliphatic monocarboxylic acid or ester containing 10 to 60 carbon atoms followed by reacting it with a monomeric, oligomeric, or polymeric diol. In one preferred version, the moisture-resistant polyol is a branched polyester polyol containing 36 carbon atoms. The composition can be prepared using prepolymer or one-shot manufacturing techniques. The thermoset composition has good cross-link density. The resulting golf ball has desirable playing performance properties including high resiliency, toughness, impact durability, moisture-resistance, and soft feel.
