Patent EP-0288926-A2 (EP)
Inventor: NEUMULLER HERMINE
IPC: A47J27/04
Filed: 1988-04-22
Abstract: In a vessel (1) for cooking food in a microwave oven, in order to prevent electrical discharges between the metallic vessel (1) and the metal cover (2), these parts must be spatially separated from one another. To this end, the metal cover (2) and the vessel (1) are designed relatively to one another in such a manner that the intermediate medium, e.g. of plastic, at the same time largely also forms a necessary accessory of the vessel. This intermediate medium is represented as a water container (3), which has an edge strip (10), underneath its upper edge (8), projecting at right angles and surrounding it on all sides, and in which the metal vessel is inserted. This vessel is covered by means of the metal cover (2) which is supported on the circumferentially projecting side edge (10) of the water container (3) with its lower edge (11) of its edge region (5) which overlaps the water container (3) and the vessel (1). This separation of the metallic media (1 and 2) allows food to be cooked in a microwave oven without a spark discharge from metal part (1) to metal part (2). <IMAGE>

Abstract: The packaging units, in particular for accommodating and/or storing sterilisable preparations for parenteral use or dialysis fluids, comprise a container having at least one discharge spout and comprising nylon 66 or a laminate of nylon 66 film and polyolefin film, the polyolefin film being arranged on the side facing the fluid to be stored and the nylon 66 film being arranged on the outside, and the two films being bonded in a conventional manner by means of an adhesive. The packaging units may also have an internal container or an external container. The packaging units are produced by producing a container having at least one discharge spout from nylon 66 or the abovementioned laminate, filling this container with the fluid to be stored, then sealing and sterilising the container, and subsequently, if desired, covering the container, after cooling and drying, with an external container of a polymeric material. It is also possible to produce packaging units according to the invention by producing an internal container having at least one discharge spout from a polymeric material, filling this container with the fluid to be stored, sealing the container, then covering the container with an external container of nylon 66 or a laminate of nylon 66 film and polyolefin film, the polyolefin film being arranged on the side of the laminate facing the internal container and the nylon 66 film being the outer film, and subsequently sterilising the container.

Abstract: A semiconductor device is disclosed, which compri­ses source and drain regions (21a, 21b) formed in a spaced-apart relation to each other on an isolated semi­conductor substrate surface (21), a first conductive layer (24) formed over a channel region between the source and drain regions (21a, 21b) via a gate insu­lating film (23) and serving as a floating gate electrode, a two-layer insulating film (25, 26) formed on the first conductive layer (24) and consisting of a silicon oxynitride film and a silicon oxide film, and a second conductive layer (27) formed on the two-layer insulating film (25, 26) and serving as a control gate electrode. In the semiconductor device of this struc­ture, the silicon oxynitride film traps less electrons, and electrons are difficultly trapped at the time of data erasing, so that data-erasing characteristics can be improved. Further, since less electrons are trapped, unlike the prior art insulating film utilizing a silicon nitride film, there is no need of providing any silicon oxide film on each side, and with the two-layer struc­ture consisting of the silicon oxynitride film and a silicon oxide film it is possible to obtain sufficient insulation and film thickness reduction.

Abstract: High modulus thermoplastic compositions and composites are produced which exhibit enhanced melt integrity and strength, allowing the composites to be melt-drawn to smooth surfaced, high tolerance profiles, such as thin-walled tubing, wire, coatings, films, etc. The melt integrity is improved by adding to the thermoplastic prior to or during thermoplastic melt processing a silicone component which will be vulcanized within the thermoplastic to form a silicone semi-interpenetrating polymer network initiated during the melt processing of the thermoplastic. The composition contains about 0.1 to 20, and preferably about 1 to 4 weight percent of the silicone network, and may also contain fibrous reinforcement and/or filler/modifiers.

Abstract: For a feeding device of a printing machine, a suction separating device is proposed, which, in the event of an inclination of the suction separator in or opposite to the sheet run direction, exerts no disruptive influence on the further transport of a sheet lifted off a sheet stack and makes possible without great operational effort a change of the inclination of the suction separator with the printing machine running. To this end, a support shaft for the suction separator aligned opposite it is mounted pivotably in a lifting gear for the support shaft and is connected in a rotationally fixed manner to a connecting rod, which is guided in selectable pivoting positions essentially parallel to itself, of a pivoting device for the selectable pivoting positions (Fig. 1). To adjust the pivoting positions, adjusting means are provided, which in a further development of the invention are controlled by a scanning device for the surface of a bent stack edge. …<IMAGE>…

Abstract: A bush-type vibration damping device (10) having an inner cylinder (12) and an outer cylinder (14) arranged in such a way that their axes extend in parallel with each other, and an elastic member (26) is interposed between the inner and outer cylinders (12 and 14). A pressure receiving chamber (34), a first sub-liquid chamber (42) and a second sub-liquid chamber (48) are provided at one side of the inner cylinder (12). The first sub-­liquid chamber (42) has a not smaller resistance to expansion by pressure than the second sub-liquid chamber (48). The first and second sub-liquid chambers (42, 48) are connected to the pressure receiving liquid chamber (34) through first and second communication passages (36,46), respectively. The second communication passage (46) produces a not smaller resistance to flowing liquid than the first communication passage (36). Vibration of a comparatively low frequency and large amplitude is absorbed by the flow resistance encountered by a liquid displaced through the second communication passage (46), while vibration of a comparatively high frequency and small amplitude causes a resonance of the liquid in the first passage (36) so as to limit increase in the dynamic spring constant.

Abstract: A digital data processing system including a plurality of processors, each including a central processor unit for processing programs at predetermined synchronization priority levels and a cache memory. A memory shared by all of the processors includes an synchronization level table which identifies a processor operating at each synchronization priority level. A common bus interconnects the processors and the memory. When a processor is to execute a program, it adjusts its synchronization priority level to a predetermined synchronization priority level. To do that, the processor accesses the synchronization level table over the common bus to determine whether the level is accessible and, if so, places an entry in the table to indicate that the synchronization priority level is occupied. If the synchronization priority level is not accessible, the processor continually monitors the entry in the table over the common bus to determine when it is accessible. To accomplish that, the processor monitors its cache, which contains a copy of the table entry associated with the synchronization priority level. When the synchronization priority level becomes accessible, the cache copy is invalidated so that the processor then has to use the table. Until the synchronization priority level does become accessible, however, the processor uses the cache copy of the table entry which reduces accesses of memory.
