摘要:
The invention provides a multi-piece solid golf ball having a core, an envelope layer which encloses the core, an intermediate layer which encloses the envelope layer, and a cover which encloses the intermediate layer and has formed on a surface thereof a plurality of dimples. The core is formed primarily of a rubber material, the envelope layer is formed primarily of a specific resin mixture, the intermediate layer is formed primarily of a resin material, and the cover is formed primarily of polyurethane. The intermediate layer and the cover have surface hardnesses (Durometer D hardness) which satisfy the relationship: intermediate layer surface hardness>cover surface hardness. The golf ball has an excellent flight performance and controllability that are acceptable to professionals and other skilled golfers, while also having an excellent durability to cracking on repeated impact and an excellent scuff resistance.

A metallic gasket including a base plate having a convex metal bead formed, by bending the base plate, between a combustion chamber opening and on the outer periphery portion of the base plate, and a first thickness-increased portion formed thicker than the remaining portions of the base plate to provide a difference in thickness, by which a surface pressure is made to concentrate on the first thickness-increased portion to seal a joint between a cylinder head and a cylinder block when the metallic gasket is disposed between the joint surfaces of the cylinder head and the cylinder block and fastened by clamping bolts. An elastic sealing material is fixed to the convex portion of the metal bead and filled in a concave portion on the reverse side of the base plate to form a rubber bead, and the sealing material is deformed under compression in the through-thickness direction in cooperation with the deformation of the metal bead when the gasket is fastened with clamping bolts. This gasket reduces production cost and preserves a stable sealing performance for extended periods of time.

A technique for determining a match between a character string including an evaluation and product information stored in a storage device and including a feature description of a product. The character string includes a name of an evaluation object to be evaluated and an evaluation expression representing the evaluation of the evaluation object. The matching method includes a first determining step of determining from the evaluation object and the evaluation expression whether the evaluation expression represents a positive evaluation of the evaluation object or a negative evaluation of the evaluation object; and a second determining step of determining, when the evaluation expression represents a positive evaluation of the evaluation object, if the evaluation expression is included in a feature description of a product, the product to be a matched product, and if the evaluation expression is not included in a feature description of a product, the product to be a mismatched product.

摘要:
The present invention provides a method of manufacturing a golf ball having a solid core formed of a rubber composition and a cover of at least one layer encasing the core, which method includes the steps of treating a surface of the core with a solution containing a halogenated isocyanuric acid and/or a metal salt thereof, and covering the treated core with a cover material. The invention also provides a golf ball obtained by such a method. Golf balls obtained by this method have a good feel and a good scuff resistance, and also have a high durability to impact.
摘要:
The present invention provides a golf ball having a core, an intermediate layer encasing the core, and a cover which encases the intermediate layer and has formed on a surface thereof a plurality of dimples. The core is formed primarily of a rubber material, and the intermediate layer and the cover are formed primarily of like or unlike resin materials. The core has a hardness which gradually increases from a center to a surface thereof, the hardness difference in JIS-C hardness units between the core center and the core surface being at least 15 and, letting (I) be the average value for cross-sectional hardnesses at a position about 15 mm from the core center and at the core center and letting (II) be the cross-sectional hardness at a position about 7.5 mm from the core center, the hardness difference (I)-(II) in JIS-C units being not more than ±2. The intermediate layer and cover have hardnesses which satisfy the condition: cover hardness>intermediate layer hardness. The golf ball of the invention has an improved distance, and also has an excellent durability to cracking on repeated impact and an excellent scuff resistance.
