Abstract: Disclosures of the present invention describe an antenna device by forming a HF conductive section, a ground electrode, two first LF conductive sections, two first bending conductive sections, two second LF conductive sections, and a second bending conductive section on one surface of a substrate as well as disposing a cover electrode on the other surface of the same substrate. The HF conductive section is designed to have an area extending portion for making a horizontal electrical coupling occur between the area extending portion and the two LF conductive sections. Moreover, the cover electrode covers a portion of the second bending conductive section, all of the ground electrode, a portion of the signal inputting portion, and a portion of the two LF conductive sections, such that a vertical electrical coupling is achieved for enhancing the efficiency of the antenna device during the transmission of LF signal.

Abstract: The present invention is an electrical signal computing module capable of accommodating printed circuit board, able to lead the exterior air into the main case body, exchange heat with the printed circuit boards, without accumulation of heat and damage of the printed circuit board. The present invention has a main case body with a bottom case and an internal board set, and four accommodating areas are formed by the internal board set and a transmission circuit board, in addition, numerous flow holes disposed at specific position are designed for air flowing in, exchanging heat produced by printed circuit boards as well.

Abstract: The present invention relates to an industrial server system, comprising a housing, a backplane, at least one rear board, a first front board, a second front board, and a power supply, wherein the backplane and the power supply are disposed in the housing, and the rear board, the first front board, and the second front board are coupled and configured to the backplane. Four connected blocks are disposed on the backplane, which makes that at least one rear board, the first front board, and the second front board are able to communicate to each other by a plurality of data connecting units disposed on the backplane. The rear board, the first front board, and the second front board of the present invention can achieve a great transmission efficiency by a specific configuration of connected block on the backplane.

Abstract: A server structure with a replaceable heat-dissipating module comprises at least one heat-dissipating module receiving slot and at least one heat-dissipating module. The heat-dissipating module receiving slot is provided in a case and has two lateral walls each provided with a sliding groove. The heat-dissipating module further comprises a heat-dissipating element and two side boards. The two side boards are located at two sides of the heat-dissipating element for engaging with the sliding grooves, respectively, so that the heat-dissipating module receiving slot replaceably receives the heat-dissipating module therein.

Abstract: A server with a replaceable module includes a housing, at least one carrying mechanism and at least two urging units. The carrying mechanism further has a carrying seat, a first cover plate, at least two retaining plates and at least two fastening members. Each of the two urging units has a second notch and an exerting portion. Therein, when a user exerts a force on the exerting portions, the fastening members are ejected out form the housing, and the carrying mechanism is ejected out of the housing simultaneously.

Abstract: A server with an improved connecting port is provided. The server comprises a casing, a fastening module and a connecting port. The fastening module is disposed in an internal receiving space of the casing and further comprises a fastening base plate with a first through hole, a first fastening plate with a second through hole, and a second fastening plate with a third through hole. The connecting port has two ends connected to two engaging wings, respectively. The connecting port is inserted into the first through hole, the second through hole, and the third through hole. The engaging wings are embedded in the second through hole and held by and between the fastening base plate and the second fastening plate.
