    • PROBLEM TO BE SOLVED: To provide a golf ball which has a suitable spin rate in a short game and can thus manifest a good controllability, yet which holds down the spin rate on shots with a driver, enabling an excellent flight performance to be achieved, and which moreover provides a good feel at impact.SOLUTION: In a golf ball including a core, an intermediate layer and a cover, the intermediate layer formed of an ionomer resin material having a high degree of neutralization is combined with a cover formed of a material that includes a first ionomer resin having a high unsaturated carboxylic acid content and a second ionomer resin having a low unsaturated carboxylic acid content. The golf ball is able to achieve a lower spin rate on full shots with a driver (W#1) without reducing the spin performance on approach shots in the short game, provides high levels of both flight performance and controllability, and also has a good feel at impact.
    • 要解决的问题:为了提供一种在短时间内具有合适的旋转速率的高尔夫球,并且因此可以表现出良好的可控性,而这种高尔夫球可以降低驾驶员的射击速度,从而能够实现优异的飞行性能, 并且还提供了良好的冲击感。解决方案:在包括芯,中间层和盖的高尔夫球中,由具有高中和度的离聚物树脂材料形成的中间层与由 包含具有高不饱和羧酸含量的第一离聚物树脂和具有低不饱和羧酸含量的第二离聚物树脂的材料。 高尔夫球可以在驾驶员(W#1)的全速下实现更低的旋转速度,而不会在短距离射门中降低旋转性能,提供高水平的飞行性能和可控性,并且还具有良好的 感觉到影响。

    • PROBLEM TO BE SOLVED: To provide a golf ball 2 having excellent flight performance.SOLUTION: The surface of a golf ball 2 is divided by four comparting great circles CG into six spherical quadrangles Ss and eight spherical triangles St. The eight spherical triangles St are composed of four first spherical triangles St1 and four second spherical triangles St2. Dimple patterns of the six spherical quadrangles Ss are the same. Dimple patterns of the four first spherical triangles St1 are the same. Dimple patterns of the four second spherical triangles St2 are the same. The dimple pattern of each first spherical triangle St1 is different from the dimple pattern of each second spherical triangle St2. The comparting great circles CG are obtained by projecting the 24 sides of a cuboctahedron inscribed in a phantom sphere of the golf ball 2 on the surface of the phantom sphere.
    • 要解决的问题:提供具有优异飞行性能的高尔夫球2。

      解决方案:高尔夫球2的表面由四个相连的大圆CG分成六个球形四边形S和八个球形三角形St.八个球形三角形St由四个第一球形三角形St1和四个第二球形三角形St2 。 六个球形四边形Ss的凹凸图案是相同的。 四个第一球形三角形St1的三维图案是相同的。 四个第二球形三角形St2的三维图案是相同的。 每个第一球形三角形St1的凹坑图案与每个第二球形三角形St2的凹坑图案不同。 通过将雕刻在高尔夫球2的幻影球上的立方八面体的24个侧面投射在幻影球的表面上,获得相配的大圆CG。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a golf ball for professionals and other skilled golfers, which is endowed with an excellent flight performance and good controllability, while also having an excellent durability to cracking on repeated impact and an excellent scuff resistance. SOLUTION: The multi-piece solid golf ball has a core, an envelope layer which encloses the core, an intermediate layer which encloses the envelope layer, and a cover which encloses the intermediate layer and has formed on a surface thereof a plurality of dimples. The core is formed primarily of a rubber material, the envelope layer is formed primarily of a specific resin mixture, the intermediate layer is formed primarily of a resin material, and the cover is formed primarily of polyurethane. The intermediate layer and the cover have surface hardnesses (Durometer D hardness) which satisfy the relationship: intermediate layer surface hardness > cover surface hardness.
