Abstract: A manufacturing method of a clubface of a golf club reduces the amount of the metallic material used and enhances production. The manufacturing method includes the following steps: a metal powder and a binder are mixed to form a mixture; the mixture is shaped by a clubface mold to form a primary clubface; the primary clubface is then heated to a sintering temperature of the metal powder to form a clubface, before the clubface is finally compacted to make it stronger and increase the clubface's density.

Abstract: A clubface of golf club head and a method for fabricating the same can fabricate the clubface in mass production and will not consume much more valuable metal. The method has the following steps: firstly, a conductive top mould and a conductive bottom mould are provided. Then, titanium powder is placed on the conductive bottom mould and press down the top mould. Following, the conductive top mould and the conductive bottom mould are electrified. The conductive top mould is provided with consistent pressure to contact with the conductive bottom mould, and consistently electrifying the conductive top mould and the conductive bottom mould for a predetermined period. After that, removing electricity, and removing the conductive top mould and taking out the clubface of the golf club head.

Abstract: A device for preventing a low-melting point heat-transfer medium from oxidization is proposed. The device has a heat sink, a low-melting-point alloy, and an oxidization-proof layer. The low-melting-point alloy is disposed on the heat sink and serves as a heat-transfer medium to contact a heat source. The oxidization-proof layer is made of a condensable material and disposed on the heat sink. The oxidization-proof layer surrounds the low-melting-point alloy. The oxidization-proof layer can effectively prevent the low-melting-point alloy from invasion by ambient air by isolating the low-melting-point alloy from the ambient air. Hence, the oxidization of the low-melting-point alloy is prevented and the high heat-transfer efficiency of the low-melting-point alloy is kept.

Abstract: An electrode of a cold cathode fluorescent and manufacturing method thereof has an integral structure that makes it easy to increase the discharge area of the discharge portion and raise production output. The manufacturing method of the electrode has the followed steps: mixing metal powders and binders to form a mixture; shaping the mixture in an electrode die to form an electrode mold base; heating the electrode mold base until a sintering temperature to form an electrode; and compacting the electrode for increasing its intensity.
