First break down the object into several basic solids, then draw the isometric drawing of each basic solid. One elementary solid is added to another in proper order to complete the construction. Example 1:Given the main and top views of a regular hexagonal prism, draw its isometric projection...
A 4D cube projects into a 3D hexagonal prism segment. The final result is a layer structure quasiperiodic in one direction and periodic in the perpendicular plane. The structure promises to be useful as a simple model of an aperiodic crystal.doi:10.1080/00150190490462342...

Two different chiralization pathways with different values of m and i are found for the octahedron, cube, hexagonal bipyramid, and icosahedron. Many less symmetrical chemically significant polyhedra have the degree 2 ligand partition (v - 2, 2) as the lowest degree chiral ligand partition and ...
attempts have been made recently to change the wavelength of light for exposure, from the g-line to the i-line or to excimer laser light of a wavelength not longer than 300 nm. This aims at an effect that the depth of focus and the resolution of an optical system can be improved in ...
A projection system having an imager panel uses a scrolling prism assembly to illuminate different portions of the imager panel with light of different color simultaneously. The scr
1. An illumination system for a microlithographic projection exposure step-and-scan apparatus, comprising: a) a light source, b) a first optical raster element that extends in or in close proximity of a first pupil plane of the illumination system and includes a plurality of first substructures...
A hexagonal prism constituted by joining the bases of two trapezoidal prisms together and forming a thin film with a half-mirror characteristic on the joined surface is arranged behind the parabolic reflecting mirror. The nearly parallel luminous flux impinges on the prism and is split into two ...

Also. there is means 6 for driving coolant air through the cylinder past the source, either by fan blades within the cylinder or by means of an external fan. The cylinder 3, which may be hexagonal, can provide colour-sequenced light directed out to a beam-splitter prism onto a digital ...
