摘要： A ceramic filter for filtering molten iron is disclosed. The ceramic filter is made from a high-melting ceramic material having an open-celled foam structure, a variable bulk density in different portions of the filter, and at least one afflux surface. In order to filter molten iron efficiently, the ratio of filter surface to filter volume should be in the range of about 0.0003 to 9 m.sup.2 /cm.sup.3, the specific filter resistance should be in the range of about 0.1 to 0.9 bar-cm at a flow rate of 5 m.sup.3 /hour, and the pressure loss .DELTA.p across the filter should depend on the specific resistance .rho., the filter length, and the surface area of the afflux plane F in accordance with the relationship: ##EQU1## A method for filtering molten iron using this ceramic filter is also disclosed. In this method, the ceramic filter is located near the point in the casting system where the molten iron has its greatest kinetic energy. The molten iron is first caused to flow tangentially by the afflux plane of the ceramic filter and then is deflected to create turbulence directly before the afflux plane of the filter.

摘要： Rotary mixing apparatus particularly suitable for treatment of foundry sand having a drum mounted for rotation about an axis which is horizontal, or at least approximately horizontal, operates to treat bulk material such as foundry sand which is placed within the rotating drum. Stationary deflection apparatus is arranged within the drum in the upper range thereof and a rotating impact rotor is mounted within the drum so that as the drum rotates and the material contained therein is propelled into the upper region of the drum it is deflected by the deflection apparatus and formed into a downwardly falling jet which is directed at the rotating impact rotor.

摘要： A nanotube array and a method for producing a nanotube array. The nanotube array has a substrate, a catalyst layer, which includes one or more subregions, on the surface of the substrate and at least one nanotube arranged on the surface of the catalyst layer, parallel to the surface of the substrate. The at least one nanotube being arranged parallel to the surface of the substrate results in a planar arrangement of at least one nanotube. Therefore, the nanotube array of the invention is suitable for coupling to conventional silicon microelectronics. Therefore, according to the invention it is possible for a nanotube array to be electronically coupled to macroscopic semiconductor electronics. Furthermore, the nanotube array according to the invention may have an electrically insulating layer between the substrate and the catalyst layer. This electrically insulating layer preferably has a topography which is such that the at least one nanotube rests on the electrically insulating layer at its end sections and is uncovered in its central section. As a result of the surface of the at least one nanotube being partly uncovered, the uncovered surface of the nanotube can be used as an active sensor surface. For example, the uncovered surface of the nanotube can come into operative contact with an atmosphere which surrounds the nanotube array. The electrical resistance of a nanotube changes significantly in the presence of certain gases. Thus because the nanotube is clear and uncovered, the nanotube array can be used in many sensor applications.

摘要： The invention relates to a transistor that is provided with a first source/drain area (S/D1), a channel area (KA) adjacent thereto, a second source/drain area (S/D 2) adjacent thereto, a gate dielectric and a gate electrode. A first capacitor electrode (SP) of the capacitor is connected to the first source/drain area (S/D1). An insulating structure entirely surrounds an insulating area of the circuit arrangement. At least the first capacitor electrode (SP) and the first source/drain area (S/D1) are arranged in the insulating area. The second source/drain area (S/D2) and the second capacitor electrode of the capacitor are arranged outside the insulating area. The insulating structure prevents the first capacitor electrode (SP) from loosing charge through leaking currents between charging and discharging of the capacitor. A tunnel barrier (T) which is arranged in the channel area (KA) is part of the insulating structure. A capacitor dielectric (KD) that separates the first capacitor electrode (SP) from the second capacitor electrode is part of the insulating structure.
