    摘要: The present invention provides an electronic component part with terminal pins very closely and very strongly bonded to a high thermal conductivity ceramics circuit board and a method for simply and continuously manufacturing electronic component parts, with a high operability, each with terminal pins bonded to a high thermal conductivity ceramics circuit board. According to the present invention, an electronic component part is provided in which terminal pins are bonded to a high thermal conductivity ceramics circuit board by a brazing metal, containing at least one kind of Group IVa elements. In another aspect of the present invention a method is provided for manufacturing electronic component parts, which comprises the step of attaching terminal pins to a high thermal conductivity ceramics circuit board by a brazing paste layer comprised of brazing metal powder containing at least one kind of Group IVa elements, an acrylic binder with a carboxylic group as a substituent group and organic solvent, and heating the resultant structure in an atmosphere containing nitrogen as a principal element so that terminal pins are firmly bonded to a circuit board.

    摘要: There is disclosed a method of joining Ni-base heat-resisting alloys which comprises forming, under an inert atmosphere, an aluminum layer on at least surfaces to be joined of a constructional member which has been divided into a plural number of parts composed of a Ni-base heat-resisting alloy reinforced by a .gamma.' phase in Ni.sub.3 Al system, followed by heating the parts so that said aluminum is dispersed in said Ni-base heat-resisting alloys, the joining portion (joint) contains substantially no .beta.-NiAl phase and a .gamma.'-Ni.sub.3 Al phase is dispersed therein to join the parts. The joint provided by the method according to the present invention has been improved in its strength and corrosion resistance at a high temperature. Further, the method according to the present invention can be carried out with a high degree of freedom in supplying a joining filler metal.
