    摘要: A method for producing a filter having partially different apparent densities comprises the steps of assembling at least two kinds of foamed bodies having different cell densities, which are formed of an organic compound such as urethane, into a three dimensional structure, immersing the obtained composite body into a slurry composed of ceramic such as cordierite so that the slurry is attached to the surface of the composite body, and firing the composite body to which the slurry is attached, to burn off the foamed bodies. By selecting the portion to be formed into high density, mechanical strength and exhaust gas purifying efficiency of the filter can be improved.

    摘要: In a compressor having a sliding member such as a portion of a vane which is disposed to be slid on an opposite member made of iron base metal, the sliding member is made of carbon fiber-reinforced aluminum having a coefficient of thermal expansion of 0.9 to 1.6+10.sup.-5 /.degree. C. in a temperature range from 0.degree. C. to 250.degree. C. and the carbon fiber-reinforced aluminum contains 15 to 40 volume % of carbon fiber which is irregularly distributed within an aluminum matrix without directional property.

    摘要: A catalyst for reforming fuel into a reformed gas rich in hydrogen comprises a catalyst carrier consisting of .gamma.-Al.sub.2 O.sub.3 and a catalyst metal mixture of the Cu--Ni--Cr type supported on the carrier, the metal mixture having the following composition: Cu = 36-62% by weight, Ni = 8-32% by weight, and Cr = 18-41% by weight, provided that Cu + Ni + Cr = 100% by weight. This catalyst is effective in reforming a fuel, especially methyl alcohol, into hydrogen over a wide temperature range from a low temperature to a high temperature. It is further improved by impregnating the carrier with at least one metal oxide selected from BaO, La.sub.2 O.sub.3, SiO.sub.2, CeO.sub.2, and SrO or by admixing the catalyst metal mixture with at least one of the oxides.
