Abstract: A memory circuit has at least two memory areas each including a group of primary read amplifiers. Each of these groups can be connected via an assigned local two-conductor data line to a two-conductor master data line whose conductors are connected to the input terminals of a secondary read amplifier. Before switching through a connection from a primary read amplifier to the secondary read amplifier, each of the conductors in both the relevant local data line and the master data line are equalized to a potential lying between two logic potentials. The supply potentials of the secondary read amplifier are provided so that the secondary read amplifier operates within the amplifying operating range when either of its input terminals is driven to the first logic potential and the other input terminal is driven to the second logic potential.

Abstract: An electromagnetic display apparatus includes a panel having substantially square pixel, which are divided into two parts. Each pixel is provided with a rotatably-mounted, bistable tilting flap, which is asymmetrical in relation to its rotational axis. The tilting flap covers one of the two portions of the panel surface in the pixel zone when the flap lies in each of its two stable positions. The side of the tilting flap facing the front side of the panel and the portion of the panel in the pixel zone, which is covered by the tilting flap and the other portion of the panel in the pixel zone has a second color. A permanent magnet is fitted to the tilting flap in close proximity to the rotational axis. The tilting flap is displaced from a first position into a second position by an electromagnet, which is located on the reverse side of the panel and is allocated to the pixels and which has a coil body and core. The apparatus is connected to a base plate, which faces the reverse side of the panel, and has at least one opening in one section of each pixel. A pin, which is located on the base plate, is allocated to each opening and is directed toward the opening. The pin contains a recess on the side facing the panel, in which a light-emitting diode is inserted.

Abstract: The integrated DRAM memory module has sense amplifiers which are each formed, in the integrated module, from a multiplicity of transistor structures that are arranged regularly in cell arrays and include amplification transistors for bit line signal amplification. The amplification transistors lie opposite one another in pairs, are structurally identical, and are arranged equally spaced apart in rows. Voltage equalization transistors ensure voltage equalization between sense amplifier drive signals. The cell array order provides for each row with amplification transistors situated in a structurally identical transistor environment to be interrupted in a predetermined period by voltage equalization transistors. The structure of the voltage equalization transistors in a region of proximity to the adjoining amplification transistors is adapted to the structure thereof, and the voltage equalization transistors are at the same distance from the mutually adjoining amplification transistors as the amplification transistors of the same row are from one another.

Abstract: The invention relates to a configuration for implementing redundancy for a memory chip, in which a fuse bank is connected to a comparator via a redundancy predecoder so that predecoded addresses can be compared with one another in the comparator and undecoded addresses can be stored in the fuse bank. This provides for a low-power and space-saving design.

Abstract: A free jet centrifuge, especially for cleaning the lubricating oil of an internal combustion engine. The aim of the invention is to provide a centrifuge which is economical to manufacture and at the same time allows for high speeds. To this end on one side of the rotor a ball bearing (16) is provided in the housing which engages a closed stub shaft (14) of the rotor. In the area of this bearing the rotor is sealed so that friction in the ball bearing is not increased by the oil pressure in the centrifuge. A friction bearing is provided for the other side of the rotor which is composed of a slide bushing (20) and a bearing bushing (21). In this way a combination of materials which is optimal in terms of tribological properties can be selected. A hollow nipple shaft (19) which acts as an oil inlet (24) for the centrifuge rotor is inserted into the slide bushing (20). To increase speed even further, the invention provides for an impulse channel (30) which discharges through nozzles (31). This device is integrated into a plastic base of the rotor (13) which permits the production of highly precise drive nozzles (31).

Abstract: A rotor (1) designed to be installed in the housing (16) of a free jet centrifuge, the rotor being provided with at least one inlet (3) and at least one outlet (4), which outlet is configured as a nozzle which is oriented at least substantially tangentially to the axis of rotation (13) of the rotor. The rotor is provided with receptacles for bearings for rotatably mounting the rotor, and the rotor having at least one guide element (7) which extends from an inner wall (38) to an outer wall (39) of a rotor interior space (8). At least the rotor shell (11) is made of synthetic resin material. Owing to its form, the synthetic resin centrifuge rotor can be made up of a reduced number of parts. The rotor may be composed of two elements, a base (10) and a shell (11), connected together either by a snap connection or by welding, such as vibration welding. An oil centrifuge fitted with such a rotor is particularly suitable for cleaning lubricating oil used in an internal combustion engine.

Abstract: In a method for the determination of the measuring uncertainty for a device for X-ray fluorescence slice thickness measurements during measurement of a layer of a sample under investigation, a spectrum S(K) simulating an actual fluorescent radiation spectrum is generated for the channels K of a spectrum and for a given thickness d of the layer and, in each channel K, a random number generator is used to repetitively accumulate a random value to construct a total number N(K) of events registered in the K-th channel in measurement time t and the standard deviation .sigma.(d) is determined from the spectrum of slice thicknesses d extracted by means of the repetitive random values as measure of the measurement uncertainty.

Abstract: An appliance for the coulometric measurement of the thickness of metallic coatings comprises a measuring probe (11) and a reversing pump device (12) with the aid of which the electrolyte fluid can be conveyed from a reservoir chamber (19) of the measuring probe (11) into the measuring chamber (17) thereof and back again. The measuring probe (11), together with the reversing pump device (12), forms a functional unit which, as a whole, can be coupled to the support device (13) and be uncoupled therefrom again. In the process, the pump drive (14) remains on the support device (13). A change of measuring probes, charged so as to be ready for service, is thus possible simply and quickly, which permits rapid measurement of a plurality of successive coatings on one measurement object to be performed. The functional unit of measuring probe and reversing pump device prevents unintentional outflow of the electrolyte fluid. It is further ensured, by means of a compression spring (56), that the electrolyte is automatically drawn into the reservoir chamber (19) if inadvertent separation from the pump drive (14) should occur.
