  • Publication number: 20190112242
    Abstract: The present application belongs to the field of energetic compounds, and particularly relates to the use of a perovskite-type compound ABX3 as an energetic material. As a finding of the present application, the structural characteristics of the perovskite type enables the type of compound to be highly stable, thus overcoming the unsafety of an explosive having poor stability in the prior art. Meanwhile, the structural characteristics of the compound, such as rich energetic ligands, as well as the alternately arranged oxidizing energetic anions and reducing organic cations in the space, endow the compound with excellent performance on instantaneously releasing energy at detonation. The resulting three-dimensional structure allows the compound to not only have an energetic material effect but also overcome shortcomings of some existing energetic materials.

  • Patent number: 9588370
    Abstract: A display device is disclosed. The display device includes a display and a diffractive optical element (DOE). The display is used to show an image. When a user looks at the image within a first viewing angle range, he can see a first observed image, and when he looks at the image within a second viewing angle range, he can see a second observed image. The diffractive optical element is disposed in the lighting direction of the display to diffract the light constructing the first observed image to the second viewing angle range, thereby converting the first observed image into a third observed image and converting the second observed image into a fourth observed image at the same time.

  • Patent number: 9011064
    Abstract: A device and method for holding a substrate, e.g., a semiconductor wafer, during a process, e.g., a liquid meniscus process, the substrate having a first side and a second side. The device includes one or more holding components, e.g., fingers, configured to contact a second side of the substrate without significantly contacting the first side of the substrate. At least one of the holding components may be configured to be moved during the process so as to prevent the at least one holding components from effecting the process, e.g., contacting the liquid meniscus. Such an arrangement may be employed when the substrate includes a top side having at least one structure or feature thereon, it being desirable that the holding components avoid contact with the structures or features during the process.

  • Patent number: 5311286
    Abstract: An apparatus and method measures the roughness or some other surface dimension by transmitting a beam of light through a grating member at an angle of incidence relative to the grating member. The grating member has a plurality of parallel opaque bars and adjacent transparent bars. The beam of light forms a multiple line shadow pattern on the surface below the grating member formed by the shadows of the opaque bars of the grating member. A camera records the multiple line shadow pattern, and the recorded pattern is superimposed on a plurality of parallel, equally spaced scan lines oriented perpendicular to the shadow lines. The distances between the points at which adjacent shadow lines cross each respective scan line are measured to determine the roughness or some other surface dimension.

  • Patent number: 4978567
    Abstract: A semiconductor wafer holding and support fixture having a low effective thermal mass comprises a planar surface having a recess for a wafer and consisting essentially of chemical vapor deposited silicon carbide. The wafer holder is specifically designed to isolate the wafer from regions of significant thermal mass of the holder. The wafer holder is particularly adapted for accomplishing chemical reactions in rapid thermal processing equipment in the fabrication of electronic integrated circuits. The method for making such an article comprises shaping a substrate, e.g. graphite, to provide a planar surface having a recess installing means for masking any regions of the substrate where silicon carbide is not desired, chemically vapor depositing a conformal outer coating of silicon carbide onto the substrate, removing the means for masking and removing the graphite by machining, drilling, grit-blasting, dissolving and/or burning.

C. Reaction conditions are maintained to assure mixing of the titanium halide gas with the other reactants only in the reaction zone and compositions of the reactant gases are limited to produce a coating comprising alpha alumina (Al.sub.2 O.sub.3) with about 2% to about 10% hexagonal alpha titanium oxide (Ti.sub.2 O.sub.3) dispersed in the alumina matrix.
