  • Patent number: 5543809
    Abstract: A dual-polarized antenna includes a planar line or surface array of reradiating elements of two different polarizations. Each reradiating element in one embodiment is a short-circuited vertical or horizontal dipole. The vertical and horizontal dipoles may be collocated on the array to form crossed short-circuited dipoles. The elements of each polarization form an array separate from the elements of the other polarization. Within each of the two separate arrays, the 1/.lambda. of each reradiator is adjusted to provide a phase shift which causes a collimated beam incident on the array to result in reradiation or "reflection" of energy in the form of a beam converging at a focal point. Therefore, each planar reradiator array acts as a parabolic reflector with a particular focal point. The focal points for the vertical and horizontal arrays are different, and a feed of the appropriate polarization is located at each of the two focal points.

  • Patent number: 5307081
    Abstract: A radiator useful for radiating pulses with a duration of about 10 ms is disclosed. Such pulses occupy the frequency band from zero to a few hundred Hertz. For a given time variation of an electromagnetic signal, the energy radiated in the far field is proportional to (Is).sup.2, where I is the current amplitude in the antenna and s is the length of the radiator. Typical antenna designs cannot be used at very low frequencies with large relative bandwidths. However, the large current radiator disclosed, herein, is small, has antenna currents in the order of 10.sup.8 A, and requires a drive voltage of about 1 volt and drive current of 10.sup.4 A. This large current radiator is designed with a small antenna length s by using a design wherein the antenna current is n times larger than the drive current. This is accomplished by winding electrically conductive means n times around a shield so that the n forward loop wires are all on one side of the shield, and cover a surface area sxW.

  • Patent number: 5051785
    Abstract: N-type semiconducting diamond is disclosed, which is intrinsically, i.e., at the time of diamond formation, doped with n-type dopant atoms. Such diamond is advantageously formed by chemical vapor deposition from a source gas mixture comprising a carbon source compound for the diamond, and a volatile precursor compound for the n-type impurity species, so that the n-type impurity atoms are doped in the diamond film in situ during its formation. By such in situ formation technique, shallow n-type impurity atoms, e.g., lithium, arsenic, phosphorous, scandium, antimony, bismuth, and the like, may be incorporated into the crystal lattice in a uniform manner, and without the occurrence of gross lattice asperities and other lattice damage artifacts which result from ion implanation techniques. A corresponding chemical vapor deposition method of forming the n-type semiconducting diamond is disclosed.

  • Patent number: 4992844
    Abstract: A first short-circuiting MOS FET with a break-through preventing function is connected between the gate and the cathode of a high sensitivity thyristor. A second MOS FET is connected between the gate and the source of the first MOS FET. A gate signal turns on the second MOS FET to reduce the gate voltage of the first MOS FET below threshold voltage. In turn, the short-circuit of the gate to the cathode of the thyristor is removed. Specifically, the gate signal is applied to the gate of the thyristor to trigger it. When forward voltage VAK applied between the anode terminal and the cathode terminal of the thyristor element is larger than the threshold voltage of the first MOS FET, the gate of the first MOS FET is biased to a voltage above the threshold voltage so that the first MOS FET is turned on. Therefore, the gate and the cathode of the thyristor element are short-circuited to prevent the break-through of the thyristor due to the an external transient surge voltage.
