摘要： PROBLEM TO BE SOLVED: To produce a high strength Al alloy easy of porthole extrusion by regulating the hardness of a high strength Al alloy to specific Vickers hardness by annealing treatment before extrusion and further regulating its hardness to specific Vickers hardness by plastic working. SOLUTION: At the time of extruding a high strength Al alloy, an Al alloy ingot before extrusion is heated and held at about 440-550 deg.C and cooled to remove internal stress and homogenize the ingot, by which a Vickers hardness of >=Hv40 is provided. Subsequently, plastic working is applied to the homogenized Al alloy ingot at =40% working rate to develop work hardening, by which a Vickers hardness of >=Hv20 is provided. By this method, the high strength Al alloy easy of porthole extrusion can be obtained.

摘要： PROBLEM TO BE SOLVED: To cool electronic components which generate a heat and utilize effectively a part of thermal energy emitting during cooling. SOLUTION: A cooling device 1A for electronic components is comprised of a radiating part 2, which is brought into contact with an electronic part 6, a cooling vessel 3 where a refrigerant R is fed and discharged, a thermoelectric element 4 which is inserted between the radiating part 2 and the cooling vessel 3 in a manner such that it is in contact with the surface 21 of the radiating part 2 and the outer surface 34 of the cooling vessel 3, and a heat transporting pipe 5A whose one end 50a is brought into contact with the radiating part 2 and the other end 52a with the cooling vessel 3 respectively. Thus, heat generating in the electronic components is emitted from the radiating part to the refrigerant in the cooling vessel 3 via the pipe 5A, so as to cool the electronic components, and at the same time, the thermoelectric element 4, which is given a high heat transmitted from the electronic components through the radiating part and a low heat transmitted from the refrigerant via the cooling vessel 3, generates an electric power thanks to the difference in temperatures between the high heat and low heat.

摘要： PURPOSE:To combine high strength with high toughness, in an as-cast state, in a non-heat treated type aluminum alloy casting. CONSTITUTION:The composition of a material is regulated so that it consists of, by weight, 3-5% Mg, 3-5% Zn, 0.3-1.0% Mn, 0.005-0.06% B, 0.05-0.8% of elements selected from the group consisting of Ti, Zr, Cr, and V, and the balance Al. A molten metal of this material is poured into a mold and then solidified and cast at a cooling rate where the maximum cooling rate between liquid phase and solid phase becomes (50 to 300) deg.C/sec. By this method, borides and intermetallic compounds are refined by rapid cooling and, as a result, alpha-Al phase is refined and the strengthening of entering into solid solution is accelerated, by which strength and toughness can be improved.
