Benefits of technology

[0016] The golf ball of the invention bears on itself data relating to its own manufacture history, shot history and flight properties, which ensures facile and smooth operation taken for ball quality control, ball recycling, and evaluation of ball properties such as flight performance. In particular, a knowledge about the manufacture history of each ba

Problems solved by technology

However, once golf balls are shipped from the factory, it is difficult to seize the detail of manufacture history directly.
For example, in golf practice ranges where balls are used at very high frequencies, it is difficult to time the replacement of overused balls.
However, it is unknown how many times the ball has been recycled.
Although the parameters of a golf ball are measured and recorded by the

Example

[0037] Now, the golf ball G shown in FIG. 3 is described as a second embodiment of the invention. The golf ball G is a three-piece solid golf ball comprising a solid core 1 and a cover of two layers 2a and 2b. An IC chip 3 is embedded directly in the cover inner layer 2a that directly encloses the solid core 1, and disposed adjacent to the solid core 1.

[0038] The cover layers 2a and 2b are prepared, as described in conjunction with the first embodiment, by furnishing cover materials based on thermoplastic resins or elastomers and injection molding the cover materials around the core in a mold. The IC chip 3 directly embedded in the cover inner layer 2a is obtained by placing the IC chip in position within a mold and then injection molding a cover material therein. For example, a core is placed in a mold cavity, an IC chip is attached to the surface of the core at a selected position, and a cover material is then injected into the mold cavity. In this way, there is obtained a ball s...

Abstract

A golf ball (G) has incorporated therein an IC chip (3) which can input and/or output data relating to at least one item selected from among manufacture history, shot history and flight properties. The ball's own possession of inherent information facilitates operations including ball quality control, ball recycling, and evaluation of flight performance.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No. 2004-017386 filed in Japan on Jan. 26, 2004, the entire contents of which are hereby incorporated by reference. TECHNICAL FIELD [0002] This invention relates to a golf ball which bears data relating to its own manufacture history, shot history and flight properties so that such data may be read out and used for ball quality control, flight performance measurement or the like. BACKGROUND ART [0003] From the past, information data relating to golf ball materials, manufacture conditions and the date of manufacture and necessary for quality control of respective golf balls, are managed within a ball manufacturing factory on the basis of a manufacture number or mark engraved or printed on the ball surface. [0004] However, once golf balls are shipped from the factory, it is difficult to seize the detail of manufacture history directly. For exampl...
