Abstract: There is disclosed a magnetic alignment device and method for its fabrication in which the aligned magnetic moments of a gas enclosed within a container have an increased relaxation time, hence an increase signal to noise output.One embodiment is a nuclear magnetic resonance gyroscope including a container for gas having a layer of rubidium hydride on its inner surface. Enclosed within the container is rubidium vapor and xenon-131 gas.The layer of rubidium hydride is manufactured by reacting hydrogen gas and rubidium at a temperature between approximately 70.degree. and about 250.degree. C. In one specific method, a layer of rubidium hydride is formed by heating rubidium and hydrogen gas at about 85.degree. for about 7 days.

Abstract: A laser utilizing a unique assembly for mounting a Brewster angle window. The mounting assembly includes an elongated annular member having a transverse slot at the appropriate Brewster angle to the plane perpendicular to the axis of the annular member. A rectangular window is held in place in the slot by the tension of a leaf spring. The mounting assembly may then be inserted in place at either the anode or cathode ends of the laser and permanently held in place without introducing any stresses in the window or affecting its alignment.

Abstract: A low cost improved adjustable mirror mount is disclosed. The adjustable mirror mount includes an inner cylindrical member one end of which is sealed to a laser tube and a mirror is mounted to the other end. The midsection circumference of the inner cylindrical member may be thinner in order that it be easily deflected about its axis. An outer cylindrical member is coaxial to and surrounds the inner cylindrical member. A plurality of adjustment screws are radially disposed at the end of the outer member for deflecting the inner cylindrical member and the mirror. Thus, the angle of the mirror to the axis of the laser discharge tube is very accurately adjusted.

Abstract: A liquid crystal light valve which uses the transfer of charge carriers representing a plurality of signals from a CCD array to a liquid crystal light modulated display medium. The signal charge is extracted from the back side of the CCD by driving the CCD clock voltages to zero and allowing the charge to diffuse to the back side where it is collected in a charge depleted region formed by a reverse biased diode and injected into the interface layers of a liquid crystal display medium.

Abstract: This invention is directed to a semiconductor structure that includes at least one wafer that is fully depleted of all mobile carriers and is used as a medium for the movement of spatially modulated signal represented by charge carriers through the wafer with a spatial resolution that is smaller than the thickness of the wafer. This may be used in the form of a continuous high resolution silicon photodiode substrate to serve as an image input means for an electro-optical display medium, such as a liquid crystal. Next to the photoactivated substrate is a liquid crystal and next to the crystal is a transparent electrode. The photodiode is reverse biased and both of its sides are depleted of all mobile charges throughout its entire thickness. Thus, charges generated in the substrate move to the display not by diffusion as in prior art devices (e.g.

Abstract: There is disclosed a liquid crystal image projector which is suitable for use as an image source in an aircraft head-up display system. In this application, the projector provides extremely bright and high contrast symbology for the aircraft pilot. More generally, the projector has application wherever a television-type raster and/or calligraphic symbology display is needed. The increase in brightness and contrast ratio is achieved by using a reflector to concentrate light from a light source onto the liquid crystal display cell from whence it is reflected through an optical aperture stop in the reflector to the projecting lens and thence to a viewing surface.

Abstract: There is disclosed a dielectric reflector for selective wavelength reflection which comprises an alternately deposited series of thin films of silicon and silicon dioxide layers respectively arranged in an alternating sequence of at least one layer of each type of material. This reflector is suitable for use on the reflecting electrode of a liquid crystal video display panel fabricated on a semiconductor substrate. The use of the dielectric reflector in place of other types of reflectors increases the available reflectivity and permits a preselected color or wavelength to be preferentially reflected. The polysilicon layer of the dielectric reflector is doped with p-type or n-type impurities such as boron or phosphorus to make this layer electrically conductive.
