摘要:
A method for repairing/strengthening and crack arrest of pipe, especially metal pipe, in which, first, to cover an insulated material on the position needing repairing/strengthening and crack arrest, then to lay a high strength fiber composite material. The modulus of elasticity of the material used in the invention is close to the metal pipe's, it can be integrated with the pipe and bear the internal pressure with the pipe, thus the final composite pipe reaches required bear capacity, such as, the original most operation pressure of pipe can be recovered; and it can take effect for crack arrest of pipes when pipes happen burst accident. Otherwise, because of the insulated material is used on the bottom layer, it prevent thoroughly from galvanic corrosion between pipe and strengthening material. The method can be implemented simply and without fire, it is advantageous to tight joint between strengthening material and pipe, and between strengthening layers, and it can be used to repair and enhance the pipeline in use.

摘要:
A heat dissipation system for a miniaturized form factor card allows a communications system for mobile information devices contained in the card to operate with high heat loads by employing a high conductivity pad on the printed circuit board of the mobile information device which contacts the case of the miniaturized form factor card. Additionally, heat dissipation plugs are integrated into the edge of the PCB with emitting surfaces adjacent radiation holes in the case of the mobile information device adjacent the PCB. Heat convection channels through layers of the PCB allow transfer of heat from the pad to other conductive layers in the PCB. High thermal conductivity packing in the miniaturized form factor card conducts heat from the internal components to the case of the card in contact with the high conductivity. Placement of high heat generation components within the card case adjacent the contact interface with the high conductivity pad is also employed for maximum heat dissipation. A high conductivity membrane is provided on the card case for increased conductivity from the case into the pad on the PCB.
