    Abstract: PROBLEM TO BE SOLVED: To provide a metal wood type golf club having an improved golf club performance by disposing a high-density weight outside a natural contour of a club head.SOLUTION: The high-density weight 402 is disposed extremely outside a natural contour of the golf club head 400, thus achieving an extremely large moment of inertia (MOI) without sacrificing traditional dimensions and shapes relating to a classic pear shaped golf club.

    Abstract translation: 要解决的问题：提供一种具有改进的高尔夫球杆性能的金属木杆型高尔夫球杆，通过在球杆头的自然轮廓外部设置高密度重量。 解决方案：高密度重物402非常靠近高尔夫球杆头400的自然轮廓，从而实现非常大的转动惯量（MOI），而不会牺牲与传统的梨形高尔夫球杆相关的传统尺寸和形状 。 版权所有（C）2013，JPO＆INPIT

    Abstract: 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".
