Abstract: A shock-absorbing golf club head has a head body, a faceplate and a shock-absorbing core. The head body has a crown, a sole, a toe, a shank, a rear, an open front, a core cavity and an air outlet. The open front has an inner shoulder. The core cavity is defined in the head body and communicates with the open front. The air outlet is defined through the head body, and communicates with the core cavity. The faceplate is mounted securely on the inner shoulder of the open front of the head body. The shock-absorbing core is mounted in the core cavity. The air in the core cavity is discharged to the ambient atmosphere through the air outlet when a foaming agent serving as the shock-absorbing core foams inside the core cavity.

Abstract: A method for manufacturing a golf club head includes forming a hollow body having a crown on top of the hollow body, the crown having a rim formed on an outer periphery of the crown, a recessed area encircled by the rim, ribs formed on an inner face of the recessed area and multiple elongated bosses formed on a top face of the recessed area, removing the elongated bosses and polishing the top face of the recesses area to complete the process.

Abstract: A shock-absorbing golf club head has a head body, an inner cap, a faceplate and a shock-absorbing core. The head body has an open front, an air cavity and a core cavity. The core cavity has a cavity shoulder. The inner cap is mounted securely on the cavity shoulder of the core cavity. The faceplate is mounted in the open front of the head body and is separated from the inner cap. The shock-absorbing golf club head effectively absorbs shock and generates a sound when striking a golfball.

Abstract: A golf club head includes a hollow body with a heel, a toe, a top, a bottom, a strike plate and a rear portion.

Abstract: A method for flexibly configuring default values of a network device through an EEPROM interface is disclosed. A header is received from an EEPROM through the EEPROM interface and it is determined from the header whether any default value of the network device should be updated, and if any, how many should be updated. At least one configuration instruction is fetched from the EEPROM when it is determined that the network device should be updated.

Abstract: A method to manufacture a golf club head includes the steps of casting a head shell and welding a face plate on the head shell, polishing the golf club head, making transversal channels on the face plate, clamping the head on a vise, drilling, discharging sweeps and waste liquid from the golf club head, installing a shaft tube, polishing welded portions around the shaft tube, removing ears, and painting.

Abstract: A method for flexibly configuring default values of a network device and a network device using such flexible configuration method is described. First, it is determined whether the default values are obtained through a microprocessor interface or a memory interface. When it is determined that the default values are obtained through the memory interface, a header is received from a memory through the memory interface it is determined from the header whether any default value of the network device should be updated. If the network device should be updated, then at least one configuration instruction is fetched from the memory and the at least one configuration instruction is interpreted. A register default value of the default values is changed, corresponding to the interpreted at least one configuration instruction.

Abstract: A striking face of a golf club includes a rear face with varied thickness distribution. The rear face is divided into eight sections with an imaginary transverse line, a perpendicular line and two diagonal lines. The rear face has a joint position where the imaginary transverse line, perpendicular line and two diagonal lines join, and a joint where the rear face is adapted to engage with the golf club. The joint position has a maximum thickness, an inner peripheral edge of the joint engaging with the imaginary transverse line and the perpendicular line has a medium thickness and the inner peripheral edge of the joint engaging with the diagonal lines has a minimum thickness.

Abstract: A golf club has a head with a hollow body. The head has a neck formed at an upper portion of the hollow body. A passage is longitudinally defined through the neck. A flange is formed at a lower end of the neck and inside the hollow body. A first threaded hole is defined through the flange and coaxial with the passage. A bolt is inserted through the first threaded hole. A second threaded hole is defined through a bottom surface of the head and coaxial with the first threaded hole and the passage. A shaft has a lower end inserted in the passage of the neck. A third threaded hole is defined at the lower end and engaged with the bolt.

Abstract: A golf club has a head with a fixing hole defined therein to receive a connecting portion of a shaft fixed therein, and an adjusting means particularly provided therein to enable the head to be adjustable until a desired dynamic balance and stability of the golf club are reached. The adjusting means includes a connecting spindle having a first end thereof fixed in the connecting portion and a second end thereof formed with a connector inserted into the fixing hole of the head, and a fastening member threaded through a screw hole defined at one side of the fixing seat and extending into the fixing hole. A tip end of the fastening member formed with a cone surface is correspondingly abutted against an inclined surface formed around an annular groove defined around the connector.

Abstract: A golf club has a weight member provided between a shaft and a head thereof. The weight member is optionally made of materials with high density, and has a weight substantially equal to a weight of a standard head of a conventional golf club minus the weight of the head of the golf club of the invention. Thus, the weight of the head is less than the standard head of the conventional golf club and the whole weight of the golf club is equal to the conventional golf club, so that the twisting force applied to the head of the golf club is lessened, and the stability of the golf club is improved.

Abstract: A dynamic balance mechanism includes an adjusting barrel adapted to be adjustably extending into the club head and having a portion of the shaft securely received inside the adjusting barrel. A rotation of the adjusting barrel adjusts the relative position between the club head and the shaft.

Abstract: A golf club with high accuracy in driving a golf ball is disclosed. The golf club includes a tapered hollow shaft having a thin end and a thick end, with a weight received in the hollow shaft. A head is formed with a neck that defines a stepped hole for fixedly receiving the thin end of the shaft. Importantly, the head is made less heavy than a related standard by an amount equivalent to the weight in the hollow shaft, and so the golf club has the same gross weight as a normal club.
