摘要： PROBLEM TO BE SOLVED: To eliminate the cause of corrosion of a building body by a method wherein the building body is surrounded with a metallic plate having one surface positioned facing a ventilation space inside an outer peripheral material and the other surface formed integrally with a non-air permeable foamed heat insulation material layer. SOLUTION: A floor structure part positioned facing an underfloor space 4 communicating with outside air through a ventilation port 15 is surrounded with a metallic plate 12a and a non-air permeable foamed heat insulation material layer 13 is formed integrally with the inside. Further, a wall frame 9 is surrounded with a metallic plate 12b formed integrally with a heat insulation material layer 13 through an outer wall 8 lined with ceramic and a ventilation space 11a situated at the inner side thereof. A roof frame 10 is surrounded with a metallic plate 12c formed integrally with a heat insulation material layer 13 through a roof lining 14 and a ventilation space 11b formed at the inside thereof, and the ventilation space 12b communicates at a roof top part 16 with outside air to effect natural convection ventilation. This constitution firmly separates a heat-insulation layer 13, formed integrally with a metallic plates 12a-12c, from outside air, cuts off a flow between indoor air and outside air, and eliminates the cause of corrosion, such as condensation of dew, due to accumulation of a damp content in the building body 1.

摘要： PURPOSE:To obtain a material for electrically conductive parts of electronic and electrical appliances consisting of prescribed percentages of Mn and Mg and the balance Al with inevitable impurities and having satisfactory softening resistance, electrical conductivity, heat conductivity, solderability, platability and high mechanical strength. CONSTITUTION:A material of this invention for electrically conductive parts consists of 0.3-4.0wt% Mn, 0.10-5.0wt% Mg and the balance Al with inevitable impurities. Mn is required to obtain strength and resistance to repeated bending and softening necessary for parts such as a lead frame. Mg is an element effective in improving the strength and is added together with Mn so as to provide sufficient strength and resistance to repeated bending to parts such as a lead frame. Since the material is an Al alloy, it is much less expensive than conventional 42 alloy, 'KOVAR(R)' or Cu-base materials.

摘要： PURPOSE:To stabilize the performance of a liquid crystal display device by using an aluminum alloy sheet, thereby suppressing the temp. rise of even the display device having a large light source output and decreasing the fluctuations in temp. distribution. CONSTITUTION:The thermal conductivity of the reflection plate itself is enhanced and the heat radiation by heat conduction is accelerated by using the aluminum alloy sheet 7 as a base material. An effect of eliminating the nonuniformity in temp. by rapidly dispersing the local temp. rise is then obtd. The whiteness on the surface of the reflection plate 5 is enhanced and the reflectivity at a spectral stereoscopic angle is increased by applying a white coating plate film 6 on the reflection surface of the aluminum alloy sheet 7. The reflected of the high brightness uniform over the wide display surface is thereby obtd. The rear surface is subjected to an anodic oxidation treatment to expose an anodized oxidation film 8 so that the heat in the back light is radiated by conduction and radiation from the rear surface. The anodized oxidation film 8 enable extremel increase in the surface area. In addition, this film has a thermal conductivity as high as 0.16 and is, therefore, enhanced in heat radiation effect.
