摘要： In a solid golf ball comprising an elastic solid core and a resin cover, the cover has a JIS-C hardness of 50-85, and provided that the ball receives a spin rate S1 (rpm) in the dry state and a spin rate S2 (rpm) in the wet state when hit with a short iron having a loft of an 8-iron or greater, the percent spin retention: (S2/S1)×100 is at least 47%. The ball's spin susceptibility when hit with the short iron is not reduced in the dry state or fine weather, nor is noticeably reduced even in the wet state or rain weather. The ball has so high performance that the ball travels a distance as intended, immediately stops on the green, is easy to control and thus, suited for professional and amateur low-handicap golfers.
摘要翻译： 在包括弹性实心芯和树脂盖的固体高尔夫球中，该盖具有50-85的JIS-C硬度，并且规定球接收干燥状态下的旋转速率S1（rpm），旋转速度S2 当用具有8铁或更高的杆的短铁敲击时，处于湿润状态（rpm），旋转保留百分数：（S2 / S1）×100为至少47％。 用短铁击球时的旋转敏感性在干燥状态或晴朗的天气下不会降低，即使在湿润状态或雨天也不会明显降低。 球具有如此高的性能，使得球按预期行进一段距离，立即停在绿色上，易于控制，因此适合专业和业余的低障碍高尔夫球手。

摘要： In a multi-piece solid golf ball comprising a rubbery elastic solid core and a resin cover including at least an inner layer, an intermediate layer and an outer layer, the solid core undergoes a deflection of 1.6-6.0 mm under an applied load of 294 N (30 kgf), the cover inner layer has a Shore D hardness of 55-70, the cover intermediate layer has a Shore D hardness of 8-50 and a gage of 0.1-1.2 mm, and the cover outer layer has a Shore D hardness of 40-55. The ball prevents any undesired increase of spin upon driver shots without detracting from rebound, has good flight performance, and receives enough spin to facilitate control on short iron shots.

摘要： A wound golf ball has a wound core enclosed with a multilayer cover. The wound core consists of a center ball and a thread rubber layer. The multilayer cover includes an inner layer, an outer layer, and an adhesive layer therebetween. The adhesive layer forms a firm joint between the cover inner and outer layers whereby the ball is improved in restitution, spin and durability. The outer cover is formed of a non-yellowing thermoplastic polyurethane. The cover outer layer is injection molded on the adhesive layer.
