摘要： In a golf ball having a multiplicity of dimples of the same type arranged thereon and an equator, 6-12 dimples are arranged along the equator at an equal spacing and centered at the equator. The remaining dimples are arranged such that a great circle which does not intersect the dimples does not exist. A space where a dimple of the same size as the dimples can be formed is not left between the dimples. Due to a uniform arrangement of dimples including equator-centered ones, the golf ball is symmetrical enough to provide an increased carry and consistent flight independent of impact points.

摘要： In a golf ball having at least a set of large and small diameter dimples, the large and small diameter dimples are of the same cross-sectional shape in their lower portion. The small diameter dimple (2) has the same shape in cross-sectional view from a depth of 0.01 mm below the dimple (2) edge (3) to the bottom as that of the bottom portion of the large diameter dimple (1). A master model is prepared by feeding a cutter into a hemispherical surface of a master block to different depths while rotating the cutter, thereby forming a set of large and small recesses, respectively, wherein the large and small recesses have the same cross-sectional shape. The master model having plural types of dimples can be briefly fabricated and has increased freedom of design. Using the master model, a golf ball featuring uniform and densely distributed dimples can be manufactured.

摘要： Golf balls are manufactured by supplying a golf ball - forming material into a mold defining a cavity of a predetermined surface pattern, thereby forming a golf ball having a surface pattern transferred from the mold cavity surface pattern. The mold is prepared by way of electroforming. First using an elastic non-metal profiling material, a male duplicate master is fabricated from a female standard mold having at least one accessory for assisting molding or post machining such as a parting surface and reference surface. An electroformed mold is fabricated from the male duplicate master. This electroformed mold is ready for use as the ball manufacturing mold.

摘要： A bolt has a male screw with a surface hardening portion that has an increased surface hardness and that is applied with a compressive residual stress. The male screw is formed by cutting the bolt, and performing a process to provide at least on the surface of the male screw of the bolt the surface hardening portion that has increased hardness and that is applied with a compressive residual stress. As a result, the fatigue resistance of the male screw is improved and the bolt is effective for use in a portion where the male screw is subject to a repetitive stress.

摘要： Markings are imparted to the surface of a golf ball at the same time as the ball is molded in a two-part mold having an inner wall defining a spherical cavity. A is provided on the cavity-defining wall of the mold, and the cavity is then filled with a molding material. Also disclosed is a marking method which includes affixing a mark bearing film to the surface of a covered body comprising a core enclosed within a pair of half-cups, then compression molding the covered body. Markings can easily and efficiently be applied to a golf ball without compromising the uniformity of the dimple shapes on the ball surface.

摘要： There are disclosed a method and an apparatus for measuring the surface shape of a golf ball. A positional relationship detection process is performed by radiating laser light from the light generation section onto the surface of the golf ball at a predetermined position and receiving, through use of the light reception section, reflection light of the laser light reflected at the predetermined position on the surface of the golf ball in order to detect the positional relationship among the light generation section, the laser light radiated position on the surface of the golf ball, and the light reception section. The positional relationship detection process is repeated at a plurality of positions on the surface of the golf ball, and variation in the relative radial position of the surface of the golf ball is determined based on a plurality of positional relationships thus obtained. The surface shape of the golf ball, e.g., the surface shape of dimples, can be measured precisely.

摘要： In a wound golf ball comprising a center ball (1), thread rubber (2), and a cover, the cover consists of a first layer (3) on the wound center and a second layer (4) on the first layer. The first layer (3) is 0.5-3.0 mm thick. The second layer (4) is 10-300 .mu.m thick. The second layer (4) may be formed by either (a) injection molding a resin composition to enclose the first layer (3) or (b) press molding a resin composition film wrapped around the first layer (3). Dimples may be embossed in the first layer (3) before the second layer (4) is formed thereon. Preferably, dimples are embossed after the second layer (4) is formed on the first layer (3). The ball affords improved spin and flying distance and is fully durable.

摘要： In a golf ball of the icosahedral dimple arrangement pattern having twenty identical phantom regular triangles projected on its spherical surface, all dimples are arranged within the triangles such that no dimples may intersect the sides of each triangle and a great circle which does not intersect the dimples at all may not be depicted. Some dimples may be arranged at the apexes of each triangle. The golf ball travels a longer distance and provides consistent flight independent of impact points. Also provided is a mold consisting of upper and lower mold cups whose cavity surface is provided with dimple-forming protrusions such that the inventive dimple arrangement may be accomplished. The mold is easy to design and fabricate.
