Abstract: With the liquid crystal display provided by the present invention, the display contrast is improved by suppressing the reflection of an external light by a light diffusing layer employed in the liquid crystal display. 
     The liquid crystal display comprises a liquid crystal panel 1, a directional backlight 2 and a light diffusing means. The liquid crystal panel 1 is of the transmission type having a front face and a back face on the side opposite to the front face. A polarizing plate 4 is placed in front of the front face of the liquid crystal panel 1. The backlight 2 is placed on the back side of the liquid crystal panel 1, providing all but parallel incident illumination light beams to the liquid crystal panel 1. The light diffusing means is placed on the front side of the liquid crystal panel 1, diffusing and emitting the incident illumination light beams leaving the liquid crystal panel 1. The light diffusing means comprises a light diffusing layer 9 and transparent filler stuff 10. The light diffusing layer 9 is made up of transparent fine particles 9a spread all over the gap between the front face of the liquid crystal panel 1 and the polarizing plate 4. The transparent filler stuff 10 is used for filling up gaps among the transparent fine particles 9a. The transparent fine particles 9a each have a refraction index different from that of a glass plate 3 constituting the front face of the liquid crystal panel 1 while the transparent filler stuff 10 has a refraction index close to that of the glass plate 3.

If the system finds a missing connection within the network, it builds a gap structure within the data structure to display the missing connection. The system also sends a request to all stations on the network for station management information. After receiving this information from each station, the system builds and displays a data structure (Fig. 13) containing the physical connections between each of the stations within the network.

Abstract: An illumination system for use in photolithography having an array optical element near the formation of a desired illumination field. Light or electromagnetic radiation from an illumination source is expanded and received by a multi-image optical element forming a plurality of secondary illumination sources in a plane. A condenser receives the light from the plurality of illumination sources. A array or diffractive optical element is placed on or near the focal point of the condenser. The illumination plane formed at the focal point of the condenser is within the near field diffraction pattern of the array or diffractive optical element. There is no condenser following the array or diffractive optical element. The use of the array or diffractive optical element permits the use of a condenser between the multi-image optical element and the array or diffractive optical element having a smaller numerical aperture than the emergent numerical aperture of the diffractive optical element, and generates a desired angular distribution with little dependance on the illumination source profile. 
     When a relay is used, intermediate illumination planes may be spatially separated to form separate X and Y planes that facilitate the formation of a rectangular illumination field. The relay, unlike a condenser, simply conjugates the illumination plane with another plane or a reticle. Additionally, the use of a diffractive optical element makes possible an illumination field that has a substantially uniform illumination intensity profile along one axis and a trapezoidal illumination profile along a perpendicular axis. This illumination field profile being particularly advantageous in a scanning photolithography operation. In one embodiment, a plurality of optical multiplexers are used to condition the beam prior to being directed through the multi-image optical element. Multiplexing to create secondary beams with small lateral coherence and no mutual coherence enhances the uniformity of spacial and angular profiles. This permits efficient use of the electromagnetic radiation.

Abstract: A method and apparatus for measuring ambient stress states and material properties in underground media includes a borehole probe having a cylindrical tube formed of soft, elastic polymer material secured about a central mandrel. An upper end cap assembly removably secures the probe to a service module to provide high pressure hydraulic fluid and sensor connections. A distal end cap seals the tube to the mandrel, so that hydraulic pressure causes diametrical expansion of the tube. The end cap includes an annular seal formed of elastic polymer material and helical springs are embedded therein in the circumferential direction. The interiors of the helical springs are filled with steel pins or balls to prevent deformation of the springs. High strength fibers are bonded in the outer surfaces of the annular seal and oriented longitudinally to permit radial expansion of the seal assembly without hydraulic leakage or extrusion of the soft polymer of the cylindrical tube. An inner laminar layer comprised high strength fiber extending circumferentially about the tube and define a datum plane extending through the axis of the tube, so that the tube is expandable only in one diametrical direction. An outer laminar layer of braided steel wire mesh limits longitudinal expansion of the tube and provides a high friction outer surface for the tube. A plurality of LVDT sensors are aligned with the direction of diametrical expansion and spaced longitudinally. High pressure hydraulic fluid expands the outer tube, to drive the high friction outer surface is into the borehole wall, consolidating the borehole boundary. The fracture pressures at various angles are recorded, and analyzed to yield the principal stress vectors and material properties of the underground media.
