Abstract: PURPOSE:To attain a small size, excellent power efficient antenna with directivity for rations applications by providing a monopole antenna directly coupled with an active element of an output input stage of a transmitter-receiver and a radio wave reflecting means at a predetermined distance from the antenna. CONSTITUTION:A millimeter band antenna 1A has a monopole antenna 2A directly coupled with an active element 5A used for an input stage of a reception circuit pre-stage amplifier and a transmission circuit final stage on a semiconductor circuit 4A, and a reflection plate 3A of a radio wave reflecting means provided on a rear side of the semiconductor circuit 4A and used in common for an earth plate of the circuit 4A. Since the active element 5A and the antenna 2A are coupled directly, a feeder loss of the millimeter wave band antenna 1A is made almost zero. Moreover, the antenna 1A and the transmitter-receiver are integrated and subminiaturization is attained, and the antenna directivity for various application is utilized by changing a kind of the radio wave reflection means 3A provided to the antenna 2A at a predetermined distance and its arranged distance.

The clad material scrap is heated to about 577 to 630 deg.C in the 1st-stage furnace 1 and only the skin material (Al-Si alloy) is melted and extracted. The extracted skin material is taken out via a trough 7 into a molten metal receiver 8. The clad material scrap which is not melted is transferred to the 2nd-stage furnace 5 by a transporting device 4 while this scrap is once cooled down to about 500 deg.C. The scrap is heated to about >=700 deg.C and the core materials (Al-Mn and Al-Mg-Si systems) are melted, extracted and recovered.
