Casting compound suitable for casting an electronic module, in particular a large-volume coil such as a gradient coil, which is composed of a support material forming a matrix, one or more fillers made of inorganic microparticles, and at least one filler made of polymer nanoparticles.
摘要:
An arrangement for cooling a gradient coil has cooling tubes for coolant transport arranged for heat dissipation from coil positions of the gradient coil. Insulator plates for electrical insulation are arranged both between the coil positions and between the coil positions and the respective cooling tubes. The insulator plates include fabric layers (prepregs) that are impregnated with a reaction resin. The insulator plates exhibit a heat conductivity of greater than or equal to 0.5 W/mK.

摘要:
A projection exposure apparatus for microlithography for the production of semiconductor components includes at least one optical assembly with at least one optical element which can be actuated in a mechanically controlled manner is mounted in a structure. For carrying out the mechanical actuation, a control signal transmission device and/or an energy transmission device are/is provided, which introduce(s) no parasitic mechanical effects into the optical assembly at least during specific operating states of the projection exposure apparatus.
摘要:
The invention provides epoxy resin compounds for manufacturing prepregs and composite materials, which can be obtained inexpensively and have good processibility, and provide--without having to add flameproofing agents--virtually inflammable molded materials with a high glass transition temperature. The epoxy resin compounds contain the following constituents:(A) an aromatic and/or heterocyclic polyepoxide resin that is free of phosphorous, optionally in a mixture with an aliphatic epoxy resin;(B) an epoxy-group-containing phosphorous compound and(C) an aromatic polyamine as a curing agent.
