Abstract: An electrical contact structure (an MIS contact) includes one or more conductors (M-Layer), a semiconductor (S-Layer), and an interfacial dielectric layer (I-Layer) of less than 4 nm thickness disposed between and in contact with both the M-Layer and the S-Layer. The I-Layer is an oxide of a metal or a semiconductor. The conductor of the M-Layer that is adjacent to and in direct contact with the I-Layer is a metal oxide that is electrically conductive, chemically stable and unreactive at its interface with the I-Layer at temperatures up to 450° C. The electrical contact structure has a specific contact resistivity of less than or equal to approximately 10?5-10?7 ?-cm2 when the doping in the semiconductor adjacent the MIS contact is greater than approximately 2×1019 cm?3 and less than approximately 10?8 ?-cm2 when the doping in the semiconductor adjacent the MIS contact is greater than approximately 1020 cm?3.

Abstract: An implant includes a tubular discontinuous structure formed of a plurality of webs that at least partially extend in a longitudinal direction. The plurality of webs includes at least one joint element having a main web substantially extending in the longitudinal direction. There is a continuous gap in the main web. At least one bridge web is arranged next to the main web in a circumferential direction (U) and connected to the main web in the longitudinal direction (A) in front of and behind the gap.

Abstract: A vascular implant, in particular a prosthetic heart valve, for providing valve function, has a stent structure with a proximal conical-convex inflow region, a distal, linear cylindrical outflow region, an intermediate transition region, and a corresponding valve arrangement. When the stent structure is in the expanded state, a higher maximum radial force exists in the inlet region in direct comparison to the lower maximum radial force in the outlet region and in the transition region.

Abstract: A child-resistant container which holds at least one item. The container includes a housing having upper and lower walls and at least one open side between the upper and lower walls. The container also includes a tray having a drawer slideably positioned in the tray. The drawer is for containing the item. The tray is pivotably connected to the housing at a pivot joint for movement between a first position in which the tray and the drawer are contained in the housing for preventing access to the item and a second position in which the tray extends through the open side of the housing for exposing the drawer and the item.

Abstract: Polymerization reactor with agitator having axial action which circulates the reactor content substantially in a flow parallel to the reactor walls and parallel to the concentrically arranged interior coolers consisting of parallel U-shaped tubes; the reactor optionally containing from two to 10 horizontal tube coolers in addition.
