    • PROBLEM TO BE SOLVED: To provide a golf ball with unique combinations of compression, "feel", and spin.SOLUTION: The golf ball includes an inner core having a first outer surface and a geometric center and being formed from a first substantially homogenous composition throughout such that the geometric center has a hardness of 35 to 85 Shore C. An outer core layer is formed about the inner core, has a second outer surface and inner surface, and is formed from a second substantially homogenous composition throughout such that the surfaces have a hardness of 55 to 90 Shore C. A cover layer is disposed about the outer core layer. The hardness of the first outer surface is greater than the hardness of the geometric center to define a "positive hardness gradient", and the hardness of the second outer surface is substantially equal to or lower than the hardness of the inner surface to define a "negative hardness gradient".

    • PROBLEM TO BE SOLVED: To provide a multi-layer golf ball having an optimum spin characteristic. SOLUTION: The multi-layer golf ball 10 having a relatively hard outer core 13 surrounding a relatively soft inner core 11 having a low compression are provided. The inner core generally has a compression of less than 50, and the inner core and the outer core generally have a combined dual core compression of 50 or greater. The outer core generally has a Shore C hardness of 80 or greater. A cover 15, which may be a single-, dual-, or multi-layer cover, is provided to surround the outer core. A moisture barrier layer 14 is optionally provided between the outer core and the cover. The moisture vapor transmission rate of the moisture barrier layer is preferably less than the moisture vapor transmission rate of the cover. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供具有最佳自旋特性的多层高尔夫球。 解决方案:提供具有围绕具有低压缩的相对较软的内芯11的相对硬的外芯13的多层高尔夫球10。 内芯通常具有小于50的压缩,并且内芯和外芯通常具有50或更大的组合双芯压缩。 外芯通常具有80或更高的肖氏C硬度。 提供可以是单层,双层或多层覆盖物的盖15以围绕外芯。 防潮层14可选地设置在外芯和盖之间。 防潮层的湿气透过率优选小于盖的湿气透过率。 版权所有(C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a golf ball which includes a layer formed from a relatively soft HNP composition and a layer formed from a relatively hard HNP composition. SOLUTION: The golf balls have at least three layers, including an inner core layer, an outer core layer, and optionally an intermediate core layer. The present invention is not limited by which golf ball layers are formed from an HNP composition, so long as at least one layer is formed from a relatively soft HNP composition and at least one layer is formed from a relatively hard HNP composition. Relatively soft HNP compositions comprise a highly neutralized acid copolymer preferably having a modulus in the range from 1,000 psi to 50,000 psi. Relatively hard HNP compositions comprise a highly neutralized acid copolymer preferably having a modulus in the range from 25,000 psi to 150,000 psi. COPYRIGHT: (C)2009,JPO&INPIT
