Abstract: A golf club includes a golf club head, and a shaft extending from one side of the golf club head. The shaft and the golf club head are made as a one-piece body from a prepreg sheet including a fiber structure impregnated with a resin. The fiber structure extends continuously from the shaft to the golf club head.

Abstract: A method for forming a case of an electronic device with a wireless communication function includes: (a) providing a pair of outer prepreg layers, each containing a fiber that permits permeation of an electromagnetic wave; (b) providing a plurality of inner prepreg layers, each of which includes: a first prepreg sheet that contains a first fiber, which permits permeation of an electromagnetic wave; and a second prepreg sheet containing a second fiber that prevents permeation of an electromagnetic wave and that has a strength higher than that of the first fiber; (c) stacking and pressing the inner prepreg layers to obtain an inner laminate; (d) disposing the inner laminate between the outer prepreg layers; and (e) forming the outer prepreg layers and the inner laminate in a mold. A case for an electronic device with a wireless communication function is also disclosed.

Abstract: A method includes the steps of: (a) wrapping a stack of composite prepregs around a plate-shaped mold core to obtain a bag-like preform; (b) removing the mold core from the preform so that a receiving space is left in the preform; (c) inserting an airbag into the receiving space; (d) placing the preform together with the airbag in a mold; (e) inflating the airbag and hot pressing the preform within the mold until the preform is cured so that the receiving space is formed into a motherboard receiving space with a size sufficient to receive a motherboard of the notebook computer and so that the preform is formed into a one-piece flat housing body for the base of the notebook computer; and (f) removing the flat housing body from the mold and the airbag.

Abstract: A golf club head includes a hollow head body, a metal plate, and a compression resistant plate. The hollow head body is formed with an opening. The metal plate is fixed to the hollow head body, covers the opening, and has a thickness ranging from 0.1 to 0.5 mm. The compression resistant plate is bonded to an inner surface of the metal plate and spans the opening.

Abstract: A bicycle frame assembly includes at least one frame member having a connecting portion, and at least one shock absorber formed as a looped plate member disposed detachably in the connecting portion. The looped plate member has two resilient plate portions each having two opposite ends, and an intermediate portion between the opposite ends. The resilient plate portions are interconnected at the opposite ends. The intermediate portions of the resilient plate portions extend away from each other.

Abstract: In one aspect, the present invention relates to a method of joining wax patterns for fabricating a golf club head. In one embodiment, the method has the step of providing a prefabricated first wax pattern and a prefabricated second wax pattern, embedding a joining portion of the second wax pattern into a recess portion of the first wax pattern, heating a flange formed on the recess portion to make the flange soften, and using a flattening tool to fold the flange over and into a chambered receiving portion on the second wax pattern such that the first wax pattern and second wax pattern are melted into a whole, joined surfaces of the first wax pattern and the second wax pattern are joined tightly with no gaps, and a single wax pattern if formed.

Abstract: A combing method of wax patterns for fabricating a golf club head is provided in the present invention. Firstly, a golf club head is disassembled to two or more elements in advance, which are respectively formed into wax patterns. Next, a flange capable of being deformed upon being pressed under an appropriate temperature and a corresponding rabbet structure are predisposed on the two wax patterns, then, the temperature of the flange is raised to make it soften, and then, it is pressed into the rabbet by a flattening tool. By utilizing the softening characteristic of the wax upon being heated, the joint surfaces of the two wax patterns are melted into a single wax pattern. By the method, the two wax patterns are combined together without adding a medium there-between, and thereby forming a joint surface with no gaps.
