Abstract: PURPOSE:To manufacture the titled thin Al sheet having superior buckling resistance at high temp. by hot rolling a clad material consisting of an Al alloy contg. specified percentages of Mn, Fe, Si and Cu and an Al-Si brazing filler metal and by subjecting the resulting hot rolled sheet to cold rolling, process annealing and cold rolling to the final thickness at a specified draft. CONSTITUTION:An Al alloy consisting of, by weight, 0.6-2% Mn, <=0.3% Fe, <=0.6% Si, 0.05-0.2% Cu and the balance Al as a core material is clad with an Al-Si or Al-Si-Mg brazing filler metal as a cladding material to obtain a clad material. This clad material is homogenized, heated to a temp. below the m.p. of the cladding material and hot rolled. The resulting hot rolled sheet is cold rolled at about 10-90% draft, process-annealed by heating at >=about 300 deg.C for about 0.5-4hr and cold rolled to about 0.10-0.20mm final thickness at 30-70% draft. When the cold rolled sheet is used, thinner corrugated fins for a heat exchanger are obtd. and the weight and cost of the heat exchanger are reduced.

Abstract: PURPOSE:To enable correction to the relative luminous efficiency characteristic of human eyes by providing plural thin film-shaped evaporating filters equipped with various cut-off frequencies and arranging them so that beams to be transmitted can not be overlapped. CONSTITUTION:Thin film-shaped evaporating filters 11-13 are respectively composed of strip-shaped passing parts 11b-13b and filter parts 11a-13a which cut-off frequencies are respectively set to lambda1-lambda3.
