摘要:
There is disclosed a processing solution for metal replacement for metal aluminum or an aluminum alloy. The processing solution is used for surface processing of an underlying aluminum material. The processing solution for metal replacement removes an oxide film on the underlying aluminum material and suppresses corrosive attack to it to allow a plating film having high smoothness and good plating appearance to be deposited on the underlying aluminum material. The processing solution for metal replacement at least includes a metal salt capable of being replaced with aluminum, and an alkaline compound. A quaternary ammonium hydroxide is contained in the processing solution for metal replacement as the alkaline compound.
摘要:
A solution for removing an aluminum oxide film from an aluminum or aluminum alloy surface, which includes a salt or oxide of a metal capable of substituting aluminum, a solubilizing agent for ions of the metal, and an alkali, and which has a pH of 10 to 13.5.The removing solution makes it possible to form a film of the metal derived from the metal salt or oxide contained in the removing solution by dissolving away the oxide film from the aluminum or aluminum alloy surface at a low temperature and a high speed while restraining, as securely as possible, erosion of the aluminum or aluminum alloy surface. Besides, the removing solution ensures that even in the case where the thickness of the aluminum or aluminum alloy basis material is very small, the aluminum or aluminum alloy surface can be activated while assuredly leaving the aluminum or aluminum alloy basis material.

Electronic components differing in height (a CPU 2a, a capacitor 2b, and coil elements 2c) are mounted on a printed circuit board 1. A heat-absorbing member 3 is provided above the printed circuit board 1 in such a way that the member 3 contacts not only the top surface of the CPU 2a that is the shortest but the sides of the capacitor 2b and the coil elements 2c. To circulate a cooling medium, a flow path 4 is formed in the heat-absorbing member 3. Heat generated at the CPU 2a is transmitted from its top surface to the cooling medium in the flow path 4 via the heat-absorbing member 3; heat generated at the capacitor 2b and the coil elements 2c is transmitted from their sides to the cooling medium in the flow path 4 via the heat-absorbing member 3.

摘要:
A body flow path in a first housing having an MPU element communicates with an inner flow path and outer flow path formed in an inner heat-dissipating board and an outer heat-dissipating board, respectively, and a pump drives a cooling liquid to circulate in these flow paths. A beam is arranged between a pivot provided in a second housing and a pivot provided in the inner heat-dissipating board, a beam is arranged between the pivot of the inner heat-dissipating board and a pivot provided in the outer heat-dissipating board, and the inner heat-dissipating board and the outer heat-dissipating board are movable to the second housing. According to the operation of opening the second housing, a distance between the second housing and the inner heat-dissipating board, and a distance between the inner flow path and the outer flow path are increased.
