    • The invention provides a golf ball with a surface having a plurality of dimples formed thereon. Some or all of the dimples on the ball surface have a cross-sectional shape in which, letting a straight line passing through any one edge of the dimple and a foot of a perpendicular (pedal) dropped from an imaginary plane defined by a peripheral edge of the dimple to a deepest point of the dimple serve as a reference line, and establishing a plurality of specific regions on the reference line from the dimple edge as 0% to the pedal as 100%, the average depths of the dimple from the reference line in the respective established regions satisfy specific conditions. By reducing the air resistance during flight and thus enhancing the aerodynamic performance, this golf ball achieves a higher trajectory, enabling the ball to travel further.

    • A golf ball mold body having a plurality of mold parts with a parting surface defining a parting line along an equator and removably mating to form a cavity having an inner wall with dimple-forming protrusions, and a support pin extendable into and retractable from the cavity, the support pin extending into the cavity to support a center sphere. An end face of the support pin defines a portion of the cavity inner wall when the support pin is retracted. The support pin has a shape satisfying certain conditions, and the support pin and mold body have a gap therebetween set within a specific range. The invention minimizes formation of uneven flash caused by deflection or shifting of support pins, appearance defects caused by damage to the cavity inner wall and contamination by rubbing debris, and the life of the mold is extended.
    • 一种高尔夫球模具主体,具有多个模具部件,分模表面沿着赤道界定分型线,并且可拆卸地配合以形成具有凹陷形成突起的内壁的腔体,以及可从腔体延伸并从腔体缩回的支撑销 ,支撑销延伸到空腔中以支撑中心球。 当支撑销缩回时,支撑销的端面限定空腔内壁的一部分。 支撑销具有满足某些条件的形状,并且支撑销和模具本体之间的间隙设定在特定范围内。 本发明使得由于支撑销的偏转或移动引起的不均匀闪光的形成最小化,由于损坏腔内壁而引起的外观缺陷以及通过摩擦碎屑的污染,并延长了模具的使用寿命。

    • The invention provides a golf ball having, on a surface thereof, a plurality of circular dimples, a plurality of non-circular dimples, and a land area which is a non-dimple region composed of a plurality of arcuate first lands, each formed along an edge of one of the circular dimples, and a plurality of second lands, each arranged so as to bridge between two neighboring circular dimples and having a shape that is recessed at a center portion thereof. The non-circular dimples have an edge shape defined by a plurality of the first lands in combination with a plurality of the second lands. In this golf ball, by fashioning the lands on the ball surface into a unique shape, the surface area of the lands is minimized and the dimple surface coverage is made even larger, increasing the aerodynamic performance and thus enabling the ball to travel even farther.

    • A golf ball has a plurality of dimples, wherein: (1) the dimples have a peripheral edge with a radius of curvature R from 0.5 mm to 2.5 mm; (2) the surface coverage SR of the dimples, expressed as a percentage of the surface area of a hypothetical sphere representing the ball if it had no dimples, is from 60% to 74%; and (3) the ratio ER of a collective number of dimples RA having a radius of curvature R to diameter D ratio (R/D) of at least 20%, divided by a total number of dimples N on the surface of the ball, is from 15% to 95%. This combination of features enables damage to the paint film on the surface of the ball to be minimized, improves the durability of markings on the surface of the ball, and prevents a decline in ball performance.
