    摘要: A process for producing an internal-oxidized alloy, which comprises allowing a plasma generated in the presence of oxygen, a gas of an oxygen atom-containing compound or a mixture of oxygen and a gas of an oxygen atom-containing compound to act on an alloy consisting of at least two metal elements, thereby selectively oxidizing at least one metal element other than the matrix metal in said alloy. Particles of the internal-oxidized alloy thus obtained can, if necessary, be molded into a desired shape and sintered. Said process enables one to produce an internal-oxidized alloy at a high speed at a temperature of not more than 0.9 Tm (Tm: the melting point of the starting alloy) and does not require the step of separating an internal-oxidizing agent which step is required in the conventional process.

    摘要: A heat exchanger of a brazed-plate-fine type and a counter-flow type consists of a plurality of tube elements which define first-fluid flowing spaces while inner fins are disposed in the spaces, respectively. The tube elements are alternately laminated with a plurality of outer fins, and the laminated elements and fins are surrounded by a housing for constituting a second-fluid flowing space. A first-fluid inlet port and a first-fluid outlet ports are formed so as to outwardly project from a lateral side of the outer fin. The housing is formed to have curved portions conforming with projecting outer peripheries of the inlet and outlet ports. Accordingly, the heat transmission efficiency of the heat exchanger is improved.
