Patent DE-19807920-A1 (DE)
Inventor: ZIMMERMANN ULRICH
IPC: H01L27/112
Filed: 1998-02-25
Abstract: The invention relates to a memory cell arrangement, comprising a number of memory cells (S) arranged in a semiconductor substrate (10) with bit line trenches (1a-1d) running parallel in a longitudinal direction in the main surface of the semiconductor substrate (10). Each bit line trench (1a-1d) is provided with a first conductive area (15a-15d) in the bottom and a second conductive area (20a-20e) of the same conduction type in the top, with a channel area being provided in between in the walls of each trench. Word lines (2a-2c) run in a crosswise direction along the main surface of the semiconductor substrate (10) through certain bit line trenches (1a, 1c, 1d) for controlling the transistors provided there. An additional dopant is introduced into the trench walls of the bit line trenches (1a-1d) situated between the word lines (2a-2c) in order to increase the corresponding transistor cutoff voltage for preventing leakage currents.
Patent DE-19812321-A1 (DE)
Inventor: SIGLING RALF
IPC: B01J35/04
Filed: 1998-03-20
Abstract: Catalytic converters which operate in a dust-laden waste gas can become blocked by the individual particles (4, 5) contained in an incoming gas. The inventive catalytic converter body (1) therefore comprises a number of first longitudinal channels (2) as well as second longitudinal channels (3), the second longitudinal channels (3) having a larger channel cross-section than the first longitudinal channels (2). The invention hereby enables the individual particles (4, 5) to pass through whilst retaining the advantage of a high specific surface per volume space of the catalytic converter.

Title: Automatic lock for top of roller blind
Inventor: BUBENDORF ROBERT
IPC: E06B9/80
Filed: 1998-05-07
Abstract: The at least two links (7,8) join the top and the winder shaft and move between a wound-up position around the winder shaft, and an unwound locking position into which the links return as a result of the effect of elastic restoring pieces (12).  The elastic restoring pieces are led over an unstable equalising point corresponding to the maximum amount to which the elastic restoring pieces are under-tensioned. The elastic restoring pieces have a fixture point (13) on one link (7), and another fixture point (14) on the adjacent link(8). The fixture points describe circle arcs on the pivot axis (15) of the links.

Title: Pull-out, low-friction track roller e.g for dishwashers is made in molds rotated at intervals to form components including new low friction shell by injections, rotations and forced assembly
Inventor: HACHTEL FRIEDRICH
IPC: A47L15/50
Filed: 1998-09-22
Abstract: The roller has two assembled components (12, 13) which include running surfaces (11). A shell (15) intervenes between these and the bearing bush (14). The shell is made of plastic with low-friction characteristics.  An Independent claim is included for the method of making the roller. The shell is first injection molded. On opening the mold, the shell is held on one half. The mold halves are rotated relatively (in a turntable arrangement), until a cavity for injection of one component forming a running surface lies opposite the shell. This mold assembly is closed and plastic is injected. The second component is simultaneously injected in another cavity using the same plastic. Further relative rotation and mold alignment precedes pushing the components together. The bearing bush is injection molded in the same or a different plastic and mounted by pressing it in. Preferred features: Bush and running surface components are made of the same, or dissimilar plastic. In the method, the bush can be made in the same mold as the other components, before rotation and pressing in.

Title: Bodies from a viscose mass of used paper and added vegetable/wood fibers are formed in molds where the water is extracted under pressure and the moldings are extracted for drying
Inventor: HINZMANN NORBERT
IPC: D21J3/00
Filed: 1999-02-04
Abstract: To shape a body from a viscose mass, of paper and/or paper fibers in water together with fibers and/or chips of vegetable and wood materials, it is poured into a mold for water to be extracted and then dried. The mass to fill the mold contains 80-95 wt% water, 10-40 wt% paper fibers and 60-90 wt% chopped straw, chaff and/or other vegetable fibers.  To shape a body from a viscose mass it is poured into a mold for water to be extracted and then dried. The mass is passed into the mold in an accurate charge, with the water content to be extracted taken into account. Core dies are moved into the mold, to form mold passages and walls. A die compresses the material mass in the mold at a pressure of 500-2000 kPa for a few secs. to extract water, and the shaped mass is taken from the mold. The shaped body is dried in an air stream at 30-60  deg C.  Additives such as chopped straw and chaff, plant fibers and the like are added to the mixture of used paper dissolved in the water. After the application of pressure for a few secs., the die (15) is raised slightly, the core die is moved downwards and the frame (16) with the molds is moved upwards, so that the transport unit (18) can be moved under the mold frame (16). The mold frame (16) is moved upwards further, to press against the die for the molded bodies to be ejected downwards on to the transport unit (18) to be carried to the drying kiln.  An Independent claim is included for an assembly with a feed line (3) which is moved between end positions over the dosing supply containers (4) packed together without gaps, and a funnel (5). The funnel (5) is linked to the mixer/supply container (6). A pump (7) gives a continuous and uninterrupted delivery of the mass from the mixer/supply container (6) through the feed line (3) to the dosing containers (4). A frame (8) to carry the containers (4) has a swing axis (10) for them, and the frame (8) slides between end positions (C,D). Hoses (12) are at the dosing containers (4) over the swing axis (10) to carry the molding mass from the tilted containers (4) into the molds, with their ends at adjustable mountings on struts (13) which are fitted to the frame (8) and slide with it. A guide frame (14) has a number of dies (15). A frame (16) holds the molds. A frame (17) carries the core dies. A horizontal transport unit (18) takes off the ejected moldings. The assembly has a control to set the working operations, the successive movements and the movement path lengths. Preferred Features: One or more dosing containers (4) are fitted for each mold. A scraper plate (11) is at the struts (13), to give a scraping action to the mold openings on a retracting movement. The hoses (12) can be used in a variety of configurations for one or more molds.

Abstract: A ground lining for regulating the water balance of an area of ground has a combination of ground panels (5) which can be placed against each other and a panel covering (51) which has a number of openings (16a, b) to allow the passage of water. The ground covering (6) also comprises a panel base (52) which is located at a distance from the panel covering (51), several reservoirs (54) being provided between the panel base (52) and the panel covering (51). These reservoirs are separated from each other by dividing walls (53) that extend between the panel base (52) and the panel covering (51) and adjacent reservoirs (54) are interconnected by an overflow (55). According to prior art, moisture is only stored above the level of the panel in direct contact with the surface structure or the surface that is walked on. According to the invention, the reservoirs (54) that extend under the panel base (52) ensure a longer-lasting storage capacity and therefore a longer moisture supply phase to the structure above. Another ground lining is composed of a combination of  rectangular ground panels (5) which are laid against each other and are delimited by peripheral side walls (56). Two side walls (56) are adjacent through a corner each have a moulded-on elastic hook (8) for connecting adjacent ground panels (5).
