摘要： PURPOSE:To relax thermal stresses in joining ceramic to metal by making a composite body with glass or glass ceramic containing essential constituents of oxide of copper, Al2O3 and SiO2 and with a conductor. CONSTITUTION:A mixture of 15-40% of glass powder of mean particle diameter of 1mum selected to constitute a total amount of 100% with 55-65% of SiO2, 10-20% of Al2O3 and 15-25% of Cu2O as a fundamental composition and of 85-60% of Cu powder of mean particle diameter of 0.5mum is sintered in N2 at 700-1000 deg.C to make a plate. When joining Cu to Al2O3 or SiC, the plate is used as a thermal stress relaxation member in a structure sandwiching the plate between the metal and ceramic. Since the plate of sintered body can be made to have a coefficient of thermal expansion of 35-120X10 / deg.C, the plate is useful as a thermal stress relaxation member between electronic components and structural materials to improve the reliability of the electronic components and structural materials.

摘要： PURPOSE:To prevent the production of welding defects such as voids and others by limiting the bead sectional shape in the same direction as the bead radiation direction and rectangular to the weld line, in the specified range of the total penetration depth from the beam radiation side surface of the materials to be welded in performing welding. CONSTITUTION:Welding is performed by so adjusting the output or focus of the beam that the sectional shape of the weld beads in the same direction as the beam radiation direction and rectangular to the weld line existing in the range of 60% of total penetration depth from the beam radiation side surface of the materials to be welded becomes as follows. It is so controlled that the bead width becomes 6mm or less and the ratio of (maximum bead width/minimum bead width) becomes 1-1.7. Thereby, the welding of the captioned material of plate thickness of 50mm or more may be accomplished.

摘要： PROBLEM TO BE SOLVED: To efficiently remove NOx contained in exhaust gas of a lean burning car. SOLUTION: A CO adsorption component is incorporated into an exhaust gas purification catalyst that chemically adsorbs NOx when the air-fuel ratio of exhaust gas is higher than a theoretical air-fuel ratio and reduces the adsorbed NOx in the theoretical air-fuel ratio or below. When CO is saturation- adsorbed on the resulting catalyst at 100 deg.C and the catalyst is heated at 5-10 deg.C/min rate in a flow of gaseous He, the maximum value of CO desorption temperature is 200-220 deg.C. The catalyst is disposed in an exhaust gas passage and exhaust gas having a higher air-fuel ratio than the theoretical air-fuel ratio and exhaust gas having the theoretical air-fuel ratio or below are allowed to flow alternately.

摘要： PROBLEM TO BE SOLVED: To efficiently purify nitrogen oxides in a combustion exhaust gas from an internal combustion engine by using a catalyst prepared by depositing at least one kind of Rh, Pt and Pd, and Mn or Mn compds. on a porous carrier. SOLUTION: Alumina powder and a slurry controlled to an acidic state of nitric acid are applied on a cordierite honeycomb and then dried and calcined to obtain a honeycomb coated with alumina. The obtd. honeycomb is impregnated with an aq. soln. containing Mn nitrate, then dried and calcined. Then the Mn-deposited honeycomb is impregnated with a mixture soln. of dinitrodiamine Pt nitrate soln. and Rh nitrate soln., dried and calcined. Thereby, the obtd. catalyst contains 0.2 mol/L Mn, 0.014 mol/L Pt and 0.0022 mol/L Rh calculated as metals per 1 L volume of the honeycomb. By using this catalyst, NOx in an exhaust gas exhausted from a lean-burn car which is driven at a lean air-fuel ratio can be purified. By using Mn as the catalyst, durability against high temp. can be improved.
