| 20080220900 | GOLF BALL - The invention provides a golf ball composed of a core, an intermediate layer which encases the core, and a cover which encases the intermediate layer. The core has a diameter of 36 to 40 mm and a deflection of 3.5 to 4.2 mm, and the intermediate layer has a Shore D hardness of 45 to 55 and a thickness of 0.6 to 1.6 mm. The cover has a Shore D hardness of 63 to 66 and a thickness of 0.6 to 1.6. The ball as a whole has a deflection of 2.6 to 3.5 mm, and the intermediate layer and cover have a combined thickness of 1.8 to 2.8 mm. The ball has a hardness design such that the Shore D hardnesses of the ball components satisfy the relationship | 09-11-2008 |
| 20090209366 | GOLF BALL - The invention provides a golf ball composed of a core, a cover having a plurality of dimples on an outside surface thereof, and an intermediate layer disposed between the core and the cover. The core has a deflection, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of at least 3.0 mm but not more than 5.0 mm. The intermediate layer is formed of a highly neutralized resin material, and has a Shore D hardness of at least 40 but not more than 60 and a thickness of at least 1.7 mm but not more than 4.0 mm. The number of dimples is at least 272 but not more than 348. The golf ball, through a combination of dimples which do not cause a loss of lift in the low-velocity, low-spin rate region of the ball trajectory and a low-spin construction, travels farther and is therefore beneficial for competitive use by both skilled and amateur golfers. | 08-20-2009 |
| 20090209368 | GOLF BALL - The invention provides a golf ball composed of a core, a cover having a plurality of dimples on an outside surface thereof, and an intermediate layer disposed between the core and the cover. The intermediate layer is formed of a highly neutralized resin material, and has a Shore D hardness below 50 and a thickness of at least 1.7 mm but not more than 6.0 mm. The cover and the intermediate layer have a difference in Shore D hardness therebetween (cover Shore D hardness−intermediate layer Shore D hardness) of from 13 to 35. The cover and the intermediate layer have a combined thickness greater than 3 mm. The ball as a whole has a deflection, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of at least about 2.0 mm but not more than about 4.0 mm. The golf ball, through a combination of dimples which do not cause a loss of lift in the low-velocity, low-spin rate region of the ball trajectory and a low-spin construction, travels farther and is therefore beneficial for competitive use by both skilled and amateur golfers. | 08-20-2009 |
| 20100004072 | COLOR GOLF BALL - The invention provides a colored golf ball composed of a core, a cover having a plurality of dimples formed on an outside surface thereof, and an inside layer in contact with the cover. The ball satisfies the following conditions:

| 20100323821 | COLOR GOLF BALL - The invention provides a colored golf ball comprising a core, a cover having a plurality of dimples formed on its surface, wherein the golf ball is two-piece structure consisting of a core and a cover, and the surface of the ball is coated with a coating comprising a pearlescent pigment. The ball satisfies the following conditions:

| 20110098131 | GOLF BALL - The invention provides a golf ball having a core, at least one intermediate layer encasing the core, and a cover. The intermediate layer is formed primarily of a specific ionomer resin composition that has been highly neutralized, and the cover is formed primarily of an ionomer resin composition containing a specific amount of a granular inorganic filler. The golf ball has an excellent durability to repeated impact and a good flight performance. | 04-28-2011 |
| 20110130219 | MULTI-PIECE SOLID GOLF BALL - A multiple-piece solid core golf ball includes a solid core including an inner core layer and an outer core layer, and a cover disposed on the outside of the solid core. The inner core layer has an outer diameter of at most approximately 25 mm and is formed of a material having a loss tangent (tan δ) of at least approximately 0.1. The outer core layer is formed of a material having a loss tangent (tan δ) of from approximately 0.01 to approximately 0.1. The difference between the loss tangent (tan δ) of the material forming the inner core layer and the loss tangent (tan δ) of the material forming the outer core layer is at least approximately 0.05. | 06-02-2011 |
