	Heat shield and crystal growth equipment invention
		The heat shield is adapted for not only guiding the inert gas flow but also speeding up the flow rate of the gas and the cooling rate of the crystal so as to raise the axial temperature gradient at the solid-molten interface, the growth rate of the crystal and the productivity.
		The heat shield mainly comprises a cantilever, a vertical wall and an extension element, wherein the cantilever has a horizontal surface, and the vertical wall is connected beneath the horizontal surface of the cantilever and has a cylinder shape with a first length.

	Heat shield - Patent 6492034
		Heat shields are known, for example for use in thermal fluid flow machines and combustion chambers.
		Usually, these heat shields consist of a carrier material and a thermal insulation layer which is connected to the carrier material by means of a binder layer.
		Accordingly, the core of the invention is that the heat shield is made from a felt-like material composed of compressed and sintered intermetallic fibers.

	Revolutionary heat shield set for space test
		The first option, used on scores of manned missions, is a fixed shield made of resinous materials that safely peel away in layers as they heat up, which is followed in the final stage by the deployment of a parachute.
		Enter a new idea: a shuttlecock-shaped plastic shield that folds snugly into just 70 centimetres (two and a half feet) but is inflated on re-entry to become up to 14 metres (45.5 feet) across.
		By comparison, the heat on the inflated sides of the shield will be several hundred degrees Celsius, which the tough plastic can take "for several minutes," says Dieter Kassing, a European Space Agency (ESA) official, whose organisation has devised sensors to be used in next week's test.

		Heat Screen is capable of withstanding direct heat up to 1000 degrees F. on one side, while protecting against radiant heat up to 2000 degrees F. on the aluminized side.
		Heat Screen can be used to protect the driver's compartment from excess heat; to protect areas where excessive heat can blister paint; where exhaust pipes run close to the fuel tank; and many other applications too numerous to mention.
		The highly reflective mylar reflects the heat away from surfaces, while the foil side is oriented away from the heat source to conduct any penetrating across its surface, providing the ultimate in heat protection.

	NASA - Orion's Prototype Heat Shield Undergoes Tests
		Orion's thermal protection system serves as a barrier against the heat of re-entry to Earth through the atmosphere, Although parts of the heat shield will use shuttle tile materials, the base of it endures the most heat and will burn away, or ablate, as it descends through the atmosphere at more than 25,000 mph.
		The Orion heat shield also uses techniques perfected for the shuttle’s thermal protection system, particularly the bonding method used to attach the segments of ablative material to the base heat shield.
		The PICA material previously was used for the base heat shield of Stardust, a small robotic spacecraft that successfully completed its mission of obtaining comet samples and returned to Earth in January 2006.

	How to Install
		The heat sealing material is then used to wrap completely around the top edge of this insulation form while sticking up far enough to be folded over to the inside of the insulation form and taped to the inside of the form about 4 inches inside the top all the way around.
		The bottom of the heat sealing material, which is hanging down past the pedestal should be long enough to fold together like a package to cover the bottom of the insulation form.
		All that is necessary is to cut the Heat Shield to the appropriate sizes and using double sided tape or Velcro, attach it to the bulk head and you are almost done.

	CNN.com - Mars rover approaches heat shield - Dec 21, 2004
		During its January 25 plunge toward the red planet, the Opportunity rover was encapsulated in a protective aeroshell comprised of two key parts: a heat shield and a backshell that contained essential landing gear.
		"The heat shield campaign is focused on an inventory of the heat shield and its components, including analyses of what happened during entry and impact," he said.
		Arvidson said that along the way and next to the shield, Opportunity scientists will be conducting observations aimed at understanding the mechanical properties of the surface, based on excavations during the impact.

	Heat Shield for Spacecraft
		This re-entry is usually at a very great speed, causing tremendous heat build up from friction with the air, requiring a heat shield to protect the spacecraft.
		The heat shield helps by ablation (melting of the shield takes heat energy), by transmitting some of the heat to the air streaming by, and by insulating the spacecraft from the worst of the heat.
		By the time its speed increases to a point were the heat from friction would become a problem it is high enough that the density of air is not great enough to cause a heat problem.

		All the Heat Shield Radiant Barrier configurations yielded sizable percent savings (ranging from 16 to 40 percent) and statistically significant reductions in summer attic heat transfer compared to the non-RB case.
		It consistently showed heat flux reductions compared to the non RB case of about 40 percent for almost all ambient temperatures and even showed savings (20 to 30 percent) during mild temperature and night summer conditions.
		The percent savings during night hours and during below 35° conditions, when heating loads are the highest, are usually sizable (from 6 to 23 percent) and the differences between the RB configurations and the non-RB case are often statistically significant during these conditions.

	John F. Kennedy Space Center - Orbiter Thermal Protection System
		The space capsules were protected during re-entry by shedding layers of a heavy, resinous heat shield through a process called ablation.
		About 70 percent of an orbiter's external surface is shielded from heat by a network of more than 24,000 tiles formed from a silica fiber compound.
		Surface heat dissipates so quickly that a tile can be held by its corners with a bare hand only seconds after removal from a 2,300 degrees F oven, while the center of the tile still glows red with heat.
