Abstract: A method for making a golf tee uses a bamboo rod having a top end and a bottom end and a wooden cylinder having a top and a bottom. The method has a cutting step, a trimming step and an assembly step. The cutting step forms a concave seat in the top of the cylinder and a mounting hole coaxially in the bottom of the cylinder. The trimming step trims a pointed tip on the bottom end of the rod to form a tee shaft with a top end and a tapered sidewall in the sidewall of the cylinder to form a tee head. The mounting step mounts the top end of the tee shaft in the mounting hole in the bottom of the tee head to form a golf tee. The golf tee made from the method has a strong structure without wasting wood.

Abstract: A high-speed, directly modulated ridge waveguide laser includes: a ridge structure at a junction surface of the laser chip; and a plurality of pads only on non-active areas of the junction surface, where the plurality of pads protrude beyond an edge of the ridge structure. The laser chip can thus be held by a manufacturing tool, such that the manufacturing tool abuts the pads without abutting the ridge structure. In this manner, the ridge structure of the laser is protected from damage due to contacts by manufacturing tools, increasing the device yield of a wafer. By providing the pads only on the non-active areas of the junction surface, parasitic capacitance for contacts in the active areas can be properly controlled.

Abstract: A golf club includes a body having an opening with a first cutout defined in a periphery defining the opening and a second cutout defined in the periphery defining the opening and opposite to the first cutout and a striking face securely received in the opening and having an upper ledge corresponding to and abutting a periphery defining the first cutout and a lower ledge corresponding to and abutting a periphery defining the second cutout so that the striking face has a uniform thickness after the striking face is soldered to the body.

Abstract: A method for manufacturing a forged golf iron club head has acts of forming a body in an investment casting process, integrally forming a striking face with a hosel in a forging process and combining the striking face with the body to achieve a golf club head with a striking face. Accordingly, the iron club head has an enhanced performance with a larger profile size and more permeate weight design to gain an excellent accuracy and to prolong the distance for golf ball flying. In addition, the versatile shape design for more permeate weight or low and deep center of gravity design can help to gain the larger sweet spot area and gain more forgiveness, and makes the forged iron head to be an “easy hit” iron club iron. And it still keeps the “pure energy transmission” function of the classic forging.

Abstract: A head for a child's golf club includes a body with a face for striking a golf ball and a shank extending from the body. The shank is configured to be securely attached to a shaft of the golf club. A protective coating covers the head except the face to absorb the reactive force when striking a golf ball. The protective coating is a resilient, flexible material and is rubber in the preferred embodiment of the present invention.
