摘要:
One aspect of the invention includes a copper substrate; a catalyst on top of the copper substrate surface; and a thermal interface material that comprises a layer containing carbon nanotubes that contacts the catalyst. The carbon nanotubes are oriented substantially perpendicular to the surface of the copper substrate. A Raman spectrum of the layer containing carbon nanotubes has a D peak at ˜1350 cm−1 with an intensity ID, a G peak at ˜1585 cm−1 with an intensity IG, and an intensity ratio ID/IG of less than 0.7 at a laser excitation wavelength of 514 nm. The thermal interface material has: a bulk thermal resistance, a contact resistance at an interface between the thermal interface material and the copper substrate, and a contact resistance at an interface between the thermal interface material and a solid-state device. A summation of these resistances has a value of 0.06 cm2K/W or less.

One embodiment includes: a copper substrate; a catalyst on top of a single surface of the copper substrate; and a thermal interface material on top of the single surface of the copper substrate. The thermal interface material comprises: a layer of carbon nanotubes that contacts the catalyst, and a filler material located between the carbon nanotubes. The carbon nanotubes are oriented substantially perpendicular to the single surface of the copper substrate. The thermal interface material has: a bulk thermal resistance, a contact resistance between the thermal interface material and the copper substrate, and a contact resistance between the thermal interface material and a solid-state device. The summation of the bulk thermal resistance, the contact resistance between the thermal interface material and the copper substrate, and the contact resistance between the thermal interface material and the solid-state device has a value of 0.06 cm2K/W or less.
摘要:
An optional surface fastening system for an electronics housing facilitates its attachment to pre-manufactured fixed panel systems, enclosures and the like. The electronics housing has primary holes or slot features that interface standard screw hardware in order to fasten to varied surfaces or accepts specially designed connector pieces to mechanically attach to the aforementioned fixed enclosures. Connector pieces, designed to interface with any panel system, may be replaced interchangeably and are temporarily fixed by a snap detail located on the primary slots. Method of attaching the electronics housing to a fixed panel system requires integrated pin features on the connector pieces, employed to locate to corresponding holes on the fixed panel, in conjunction with operatives rotation of a specialized pin feature to temporarily lock the electronics housing to the panel system. Conversely while attached, operative rotation of the specialized pin feature disengages the electronics housing from the fixed panel system.
摘要:
A substrate carrier for a parallel wafer processing reactor supports a plurality of substrates. The substrate carrier includes a plurality of susceptors, which may be thermal plates or annular rings that are arranged horizontally in a vertical stack. The substrates are mounted between pairs of susceptors on two or more supports provided around the outer periphery of the susceptors. The number of substrates mounted between each pair of susceptors may the same or different but is two or more between at least one pair of susceptors.
摘要:
A winding device (24) for a textile machine (1) producing cheeses has a creel (18) for holding a cheese (11) between tube receiving plates (38, 38′), a yarn traversing device (28) comprising a separate drive (31), and a speed-regulatable drive device (27) integrated in the creel (18) to move in a bearing housing (23) of the creel (18) and connected to one of the tube receiving plates (38, 38′). The drive device (27) can be loaded with a braking current which produces a moment opposite the direction of rotation (SR) of the cheese (11), for braking the cheese (11). The drive device (27) is arranged in a sliding sleeve (35) that can be loaded pneumatically against the displacement force of spring elements (43) to move one of the tube receiving plates (38) outwardly as needed in a creel opening direction.
