Abstract: PURPOSE:To easily and efficiently join a porous body and an alloy in a half molten state of the kind different from the porous body or of the same kind to the porous body by bringing the mentioned above porous body and the alloy into contact with each other and pressurizing both, thereby infiltrating the liquid phase in the alloy into the porous body and laminating and joining the remaining solid phase to the surface. CONSTITUTION:A half sintered body of Cu is used as the porous body 23 and a Pb-Sn alloy contg. the solid phase 24 and the liquid phase 25 is used as the alloy for laminating. The mentioned above porous body and alloy are pressurized by means of punches 22 at and under a prescribed temp. and pressure in the prescribed half melting state of the solid phase fraction of the Pb-Sn alloy in a mold 21. The part which is heretofore the solid phase 24 of the Pb-Sn alloy is press welded in a laminar form to the surface of the base material consisting of the Cu and simultaneously, the liquid phase 25 of the Pb-Sn alloy is infiltrated to the Cu side in the boundary region of joining by the pressurization, by which the infiltration layer is formed. This infiltration layer and the solid phase 24 laminated thereon are thus coupled to each other.

Filed: 1979-06-18
Abstract: PURPOSE:To make easy for matching and to make small the size of ground conductor even with thick dielectric plate, by obtaining the matching element with high Q, by inserting the major part of matching element on the axis not causing electric field. CONSTITUTION:Since no electric field is caused on the axis orthogonal to the direction tying the center of the disc type radiation element 1 and the power feeding point 7 of the power feeding element 5, the major part of the matching element 10 is inserted on this axis to reduce the effect of the element 1 on the inner electric field of antenna, and the element 10 is made to triplate construction, being clipped with the radiation element 1 and the ground conductor 3 to obtain the matching element of high Q. Further, the current given to the input terminal 4 from this element flows to the element 1 through the element 10 and the power feeding element 5, and a part of current flows to the conductor 3 via the electromagnetic coupling between the element 10 and the conductor 3 to be summed with substantial ground current, allowing to suppress the unbalance current on the conductor 3 through suitable selection of the element 10. Thus, the matching can be made easy even with thick dielectric substance plate and the ground conductor can be made small in size.
