Abstract: A venous stent comprising a first vascular stent and a second vascular stent is provided, in which the first and the second vascular stents with the appropriate diameters can be selected depending on patient's veins and overlappingly combination one to another. Therefore, the venous stent of the present disclosure is preferably suitable for vascular stenosis or obstruction at or close to the confluence of veins, and can improve the matching of the stent with different patients and increase the postoperative problems caused by the inappropriate placement of stent.

Abstract: A stent-grafts combination comprising a first stent and a second stent for central veins is provided, in which the first stent and the second stent with appropriate diameters are selected depending on patient's veins and overlappingly sleeve-coupled with each other. The stent-graft for central veins can improve the matching of the stent-graft with different patients' veins, so that the surgical success rate is increased and the postoperative problems caused by the inappropriate diameters of stent-graft is decreased.

Abstract: A vapor chamber structure for at least one heating element includes a main body having a heat receiving plate. The heat receiving plate has at least one wrinkled ring portion. An inner portion of the wrinkled ring portion surrounds a contact portion. The contact portion is in contact with the heating element. Thereby, one heating element provides the contact portion a thrust when the contact portion is in contact with the heating element. The wrinkled ring portion is therefore forced to deform for helping the contact portion slightly adjust its position. This ensures a tight and even contact between the contact portion and the heating element, thereby improving the heat dissipation efficiency of the vapor chamber structure.

Abstract: A vapor chamber structure includes a plate-shaped shell and at least one stretchable heated member. The plate-shaped shell has a hollow interior to form a cavity and has a base on which at least one throughhole is disposed. The throughhole communicates with the cavity. The stretchable heated member is disposed on the base of the plate-shaped shell. The stretchable heated member includes a heated plate and a hollow stretchable tube. The heated plate is sealedly connected to one end of the stretchable tube and the throughhole of the plate-shaped shell is sealedly connected to the other end of the stretchable tube.

Abstract: The heat conduction structure includes a first heat conduction plate, a second heat conduction plate and at least one heat pipes. The second heat conduction plate is positioned below the first heat conduction plate. A pair of walls extends from two opposite edges of the second heat conduction plate. The walls connect to a bottom surface of the first heat conduction plate. A receiving space is defined between the first heat conduction plate and the second heat conduction plate. At least one heat pipe is arranged in the receiving space and sandwiched between the first heat conduction plate and the second heat conduction plate. Each heat pipe has a heat absorbing section and a plurality of heat emitting sections extending from each heat absorbing section. A plurality of heat dissipating passages is defined between the at least one heat pipe and the walls. The heat emitting sections are partially positioned in the heat dissipating passages.

Abstract: The present invention provides a complex multi-function card reader comprising a memory card module and an IC chip card module. The memory card module has at least a memory card connector; and the IC chip card module has at least an IC chip card connector. Those connectors are connecting with a plurality of peripheral circuit elements within the complex multi-function card reader and utilizing a transmission interface to electrically connect with electronic equipment. The present invention is to provide the user accessing all kinds of memory cards and the smart IC card in personal computer, notebook, the ATM, the multimedia player, the LCD TV, and the Internet phone.

Abstract: The present invention discloses the card readers installed in personal computer. The built-in card readers of personal computer include a personal computer; a plurality card reader units, wherein the plurality card reader units are installed in the personal computer mainframe, each of the card reader units containing plurality connectors, the plurality card reader units electrical connecting with the personal computer by using a transmission interface, the connector connecting with other connectors in the card readers and periphery circuit devices, and inserting memory cards into the connectors, thereby reading the memory cards data.
