摘要： A golf ball has a plurality of dimples 12 and a land 14 on a surface thereof. The golf ball further has a large number of minute projections 18 formed on surfaces of the dimples 12 and the land 14. The surface of the golf ball has an arithmetic average height Sa of not less than 0.5 μm and not greater than 30 μm. An average value Hav of heights H of the minute projections 18 is not less than 0.5 μm and not greater than 50 μm. A ratio Pp of a sum of areas of all the minute projections 18 to a surface area of a phantom sphere of the golf ball is not less than 7%. An average value Dav of diameters D of the minute projections 18 is not less than 5 μm and not greater than 50 μm.

摘要： This invention is associated with the sport of cricket in particular but not limited to and applicable to other sports and games as well where a ball is used to play. The invention relates that when a cricket ball having combinations of magnets inside with two different leathers (materials) or a combination of multi-leathers (materials) on the two hemispheres, is delivered by a bowler at a speed, an inherent swing is obtained, which is proportional to the difference in the resultant densities on the two hemispheres of the ball. The invention is aimed at providing a technology by which an inherent swing/drifted spin in the delivered ball is inevitably established which is irrespective of any seam positioning, other bowling skills, surrounding and pitch conditions.

摘要： An object of the present invention is to provide a golf ball exhibiting good shot feeling and excellent resilience. The present invention provides a golf ball comprising a spherical core and one or more cover layers disposed outside the spherical core, wherein at least one layer of the cover layers contains: (A) a base resin containing (a-1) an ionomer resin and having a material hardness of 59 or more in Shore D hardness; and (B) a polyrotaxane having a cyclodextrin with at least a part of hydroxyl groups of the cyclodextrin being modified with a caprolactone chain having a carboxyl group at a terminal of the caprolactone chain, a linear molecule piercing through a cyclic structure of the cyclodextrin, and blocking groups located at both terminals of the linear molecule to prevent disassociation of the cyclodextrin.
