    Abstract: PROBLEM TO BE SOLVED: To provide a metal wood club head with an improved striking face having a zone of high coefficient of restitution aligned in a predetermined orientation. SOLUTION: This golf club head 10 has a selectively oriented zones of relatively high flexural stiffness. The hitting face 16 is configured and dimensioned so that it includes an inner zone 36 and an intermediate zone 38. The inner zone 36 has relatively high flexural stiffness and the intermediate zone 38 has relatively lower flexural stiffness. The inner zone 36 may have an elliptical shape or a substantially parallelogram shape. Preferably, the inner zone 36 has a shape that comprises a major axis and a minor axis and the major axis aligns substantially in the direction of high heel to low toe. This arrangement of inner and intermediate zones creates a gradient of flexural stiffness in the direction of high toe to low heel and produces a COR (Coefficient Of Restitution) in that direction. This area of high coefficient of restitution advantageously coincides with the ball impact pattern that golfers typically make on the hitting face 16. The hitting face 16 also includes a measurement zone wherein the minimum COR is at least 93% of the maximum COR. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide a golf club head which includes a hitting face comprising a plurality of discontinuous zones each having different flexural stiffness, improves accuracy and increases a repulsive coefficient. SOLUTION: The hitting face comprises a directional control portion, which has at least two zones with different flexural stiffnesses. When the hitting face strikes a golf ball, the two zones deform differently to selectively control the direction of the flight of the golf ball. The directional control portion may comprise an upper zone and a lower zone, where the upper zone has a lower flexural stiffness or the lower zone has a lower flexural stiffness. Alternatively, the directional control portion may comprise a left zone and a right zone, and either the left or right zone may have a lower flexural stiffness to selectively control the lateral launch angle either to the left or right. The hitting face may further comprise a central zone disposed within the directional control zone, wherein the central zone has a flexural stiffness of at least about three times the flexural stiffness of the directional control zone.

    Abstract: PROBLEM TO BE SOLVED: To obtain a waterproof polyurea elastomer for golf implements, having a soft component for giving improved elasticity, increased cutting property, scratch and abrasion resistance, moisture proofness and increased adhesiveness without any bad influence on the whole performance and characteristic of a golf ball. SOLUTION: This waterproof polyurea elastomer is formed of a waterproof polyurea composition containing an isocyanate, an amine-terminated compound having a hydrophobic main chain and a curing agent. The elastomer forms at least a part of the golf ball including a core and a cover. COPYRIGHT: (C)2005,JPO&NCIPI
