239 For R–p examples, the prisms are stretched and the bond angles approach 120°; for the R–d cases, the prisms are compressed and the bond angles approach 109°. This geometrical study predicted that RZn, RCd, RHg, RIn, and RTl might form idealized trigonal prisms, but, instead, ...
In neutral color or gray polarizing films produced by adsorbing some kinds of dichromatic dyes in a polymeric film and orientating it, the state (cross position) wherein two polarizing films are superimposed on each other so that their orientation directions can be crossed at right angles, may ...
1. A metal coordination compound represented by one of following formulas (a) or (b): 2. An electroluminescence device, comprising: a pair of electrodes disposed on a substrate, and a luminescence unit comprising at least one organic compound disposed between the electrodes, wherein the organic...
(400-700 nm)) comprising a polymeric film which has several kinds of dichroic dyes adsorbed thereto and orientated, if two pieces of the polarizing films are superposed one upon another so that the orientation directions cross at right angles (cross-nicol state) and if in this state there ...
Hence, more fraction of fluid tends to go through louvers, which causes higher mixing and, as a result, lowers thermal resistance in comparison with other louver angles. 3.4. Compound Geometries As aforementioned, increases in louver number and width of louver, with louver angle being equal to ...
Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims. It will be understood...
are most obvious when the wall assembly is finished by painting with a gloss or a semi-gloss paint. In order to produce a painted surface that looks uniform from various viewing angles, it is desirable to more closely match both the porosity and the texture of the joint compound with those...
