    Abstract: When communication is performed simultaneously with two moving bodies such as a satellite, an antenna construction in which a plurality of antennas do not become an obstacle to each other's communication and the direction (the azimuth angle and the elevation angle) adjusting mechanism thereof can be realized with a simple construction. The two antennas have another movable portion (a rotation mechanism with respect to the axis) independently, while sharing the direction adjusting mechanism for the azimuth angle and the elevation angle. The rotation axis of the rotation mechanism of each antenna faces the same direction on the same plane, and each rotation mechanism is separately arranged in an area defined by a plane obtained by extending the axis of the azimuth angle adjusting mechanism toward the axial direction of the elevation angle adjusting mechanism. The azimuth angle and the elevation angle of respective antennas can be separately adjusted by the rotation mechanism with respect to the axis, hence the antennas can be directed to the communication targets existing in the two different directions simultaneously from the reception point.

    Abstract: A field controlled thyristor is disclosed which comprises a first emitter region exposed to one main surface of a semiconductor substrate and having a first conductivity type, a second emitter region exposed to the other main surface of the substrate and having a second conductivity type, a base region connecting the first and the second emitter region, and a gate region provided in the base region. The gate region consists of a slab-like first portion disposed parallel to both the emitter and a second portion connecting the first slab-like portion with one of the main surfaces of the semiconductor substrate. The impurity concentration of the base region is higher in the portion of the base region nearer to the emitter region having the same conductivity type as that of the base region than in the portion of the base region nearer to the emitter region having the opposite conductivity type to that of the base region. The field controlled thyristor has a high forward blocking voltage gain (anode-cathode voltage/gate bias voltage), a large current rating, and a high switching power capability and its switching time is very short.
