Abstract: A method for manufacturing a casing of a heat pipe includes steps: providing a hollow mold; injecting a feedstock of powder and molten binder into the mold under pressure, thus forming a desired body of a first shell and a desired body of a second shell; separating the binder from the body of the first shell and the body of the second; sintering the body of the first shell and the body of the second shell, thereby forming the first shell and the second shell; and mounting the second shell on the first shell and sintering the first shell and the second shell together, thereby forming the casing of the heat pipe.

Abstract: A method for manufacturing a fan blade includes the steps of, firstly, providing a mold. Then a mixture of metal powder and adhesive material is injected into the mold to forming a green body of the blade. Next, the adhesive material is removed from the green body of the blade. Finally, the green body of the blade is sintered to form the fan blade. A fan with such blades is also provided.

Abstract: A bearing device includes a body, a circular cover, and a through hole commonly defined through both the body and the cover. The body is an injection molded piece made from metal powder and molten binder. The cover is an injection molded piece made from metal powder and molten binder. Two passages are defined between the body and the cover, and each passage communicates the through hole with an exterior of the bearing device, whereby lubricant can flow from the through hole to the passages. A bearing assembly having the bearing device is also provided, and a method of manufacturing the bearing device is further provided.

Abstract: An exemplary method for manufacturing a heat pipe is disclosed. A mixture including metal powder and organic cement is made. The mixture is then injected to a mold to form two blanks. The two blanks are debinded to remove the organic cement therefrom. The two blanks are further sintered to join together and form a tube. A working liquid is filled in the tube from an open end thereof. The tube is then vacuumed to exhaust air therein. The open end of the tube is finally sealed to form a hermetic space in the tube.

Abstract: A bearing device includes a cylindrical body. The body defines an axial hole for rotatably receiving a rotatable member therein. The body defines a guiding groove at a side wall thereof. The guiding groove has a bottom end communicating a bottom of the axial hole and a top end at the body. The body defines a bore in a middle portion thereof to communicate the axial hole and the top end of the guiding groove, whereby lubricant can flow in a loop in the body.

Abstract: A method for manufacturing a bearing device includes steps: providing a hollow mold, then injecting a feedstock of powder and molten binder into the mold under pressure, thus forming a desired perform of a cylindrical body and a desired perform of a cover; separating the binder from the desired perform of the body and the desired perform of the cover; sintering the desired perform of the body and the desired perform of the cover, thereby forming the body and the cover; and mounting the cover on the body, thereby forming the bearing device.

Abstract: An electrode structure of a biosensor includes a flexible conductive substrate and a plurality of conductive probes protruding from the conductive substrate and configured for contacting a subject and receiving a physiological electric wave signal therefrom. The present invention improves disadvantages of wet electrodes and microstructure electrodes and provides more stable signals that may less decay with time so as to achieve real-time and long-acting measurement for physiological electric wave signal. A biosensor using the electrode structure is also disclosed.

Abstract: A mold device includes a mold member having a mold cavity for receiving a melted foamable material to form an object, and a pressure applying device for applying a pressure to the melted foamable material, and to limit a foaming of the melted foamable material, and for preventing orifices from being formed in an outer peripheral portion of the object, and for forming a smooth and shiny or sparkling outer appearance to the object. A mold piece is movably received in the mold cavity, and an actuator may force the mold piece to force against the melted foamable material. A pumping device may pump the hydraulic fluid into and out of the actuator.
