摘要:
The invention provides a solid golf ball having a solid core and a cover layer that encases the core and has an outermost layer on an outside surface of which are formed a plurality of dimples. The solid core is formed of a rubber composition composed of 100 parts by weight of a base rubber that includes 60 to 100 parts by weight of a polybutadiene rubber having a cis-1,4 bond content of at least 60% and synthesized using a rare-earth catalyst, 0.1 to 5 parts by weight of an organosulfur compound, an unsaturated carboxylic acid or a metal salt thereof, and an inorganic filler. The solid core has a deformation, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of 2.0 to 4.0 mm, and has a specific hardness distribution. The cover layer is formed by injection molding a single resin blend composed primarily of (A) a thermoplastic polyurethane and (B) a polyisocyanate compound, which resin blend contains a polyisocyanate compound in at least some portion of which all the isocyanate groups on the molecule remain in an unreacted state, and has a thickness of 0.5 to 2.5 mm, a Shore D hardness at the surface of 50 to 70. The golf ball has a deformation, when compressed under a final load of 130 kgf from an initial load of 10 kgf, of 2.0 to 3.8 mm. The solid golf ball is advantageous overall in competitive use.

A data processing apparatus is monitoring the first port of itself and the second port of itself. If the data processing apparatus receives data via the second port, it conducts a specific process to the data regardless of a data format of the data so as to convert the data into the data format that can be processed regardless of a data format of the data and sends converted data to the first port.
摘要:
The invention provides a multi-piece solid golf ball composed of a solid core, a cover, at least one intermediate layer situated therebetween, and a plurality of dimples on a surface of the ball. The diameter of the solid core, the deflection of the core when compressed under a final load of 130 kgf from an initial load of 10 kgf, the hardness at the center of the core, the hardness in a region 5 mm to 10 mm from the center of the core, the hardness 15 mm from the center of the core, and the surface hardness are set within specific ranges. The intermediate layer is composed primarily of a material obtained by mixing under applied heat a specific resin composition. The golf ball of the invention has an excellent flight performance, feel, controllability and scuff resistance.
