Patent DE-3741124-A1 (DE)
Title: Electron beam nanolithographic system having a multiple-beam electron source capable of multiplex control and made from MIM (metal-insulator-metal) thin-film cathodes
Inventor: NISCH WILFRIED DIPL PHYS DR
IPC: H01J37/073
Filed: 1987-12-04
Abstract: The invention relates to an electron lithography system having a multiple-beam electron source capable of multiplex control and consisting of MIM (metal-insulator-metal) thin-film cathodes. The electrons emitted from a MIM cathode array as multibeam electron source are accelerated by a perforated anode, and the cathode array is projected with the aid of an electron optical reducing system onto the substrate to be exposed. The result by comparison with the electron lithography systems having only one electron beam source is that a larger throughput of substrates to be exposed is possible. The spherical error in the electron optics which occurs in the case of the reduction of relatively large object fields is corrected due to the fact that the MIM cathodes of the cathode array which are situated remote from the electron optical axis emit faster electrons due to the application of a larger operating voltage than do the MIM cathodes near the axis.

Title: Package and packaging method for itemised articles
Inventor: NORDHUS HERMAN
IPC: B65D81/05
Filed: 1988-08-17
Abstract: In storage houses operating partially or fully automatically, it is a requirement that the package and packaging accessories take up only a small part of the storage capacity. Plastic bags which are used as packaging accessories and can be filled with air or a gas fulfil this requirement. In the method for packaging, the plastic bag (3) is filled with air or gas (8) from the outside by means of an air or gas supply device and is closed. After the filling operation, the plastic bag (3) is a shock-absorbing padding or compensating element, which spreads out in the free space of the packaging container (1), between the itemised articles (2) and the package wall of the packaging container (1). The package and the packaging method are suitable for packaging itemised articles, in particular small items. <IMAGE>

Patent DE-3840873-A1 (DE)
Title: Folding box with film window
Inventor: HEIBER WOLFGANG
IPC: B65D5/42
Filed: 1988-12-04
Abstract: The invention relates to folding boxes with film windows, wherein the film windows extend over at least one edge of the folding box or fold line and a film window is formed by a transparent film blank made of plastic which is to be stuck to the inside of the window opening in the box blank. In previously known folding boxes, the film is punched out in a V-shape in the region of the fold lines, the tip of the punch-out protruding into the window opening. This produces a relatively large opening in the folding box which, depending on the contents of the package, is undesirable. Furthermore, it is problematic with other methods that the film usually cannot yield in the region in which the compression forces occur during folding. According to the invention, to solve the problem provision is made for a cutting line (11) in the form of a flap (12) to be formed in the film blank (10) in the region of the fold line (3), which cutting line can be folded about an axis (A-B) approximately parallel to the fold line (3), and part of the flap (12) projecting beyond the window edge (4) into the window opening (2). A hot pressing zone (13) is preferably arranged on the axis (A-B) parallel to the fold line (3) in the region of the flap (12). <IMAGE>

Title: Flat closure
Inventor: FINZEL LOTHAR DIPL ING
IPC: G02B6/38
Filed: 1988-12-05
Abstract: The invention is based on the object of accommodating a relatively large number of optical waveguide splices in a space-saving and dust-protected manner. According to the invention the object is achieved in that the optical waveguide splices (5) are fastened on the two sides of the central web (2) of an H-profiled body (1). The H-profiled body (1) represents a stable mechanical protection for the splices (5). The sides of the H-profiled body (1) are sealed by a heatshrunk sleeving which is pulled over it. The heatshrunk sleeving projects over the length of the H-profiled body (1) and tightly fits around the optical waveguide bundles passed out of the flat closure. The invention is used for producing closures of small dimensions for optical waveguide splices. <IMAGE>

Title: Dynamic measurement of high value ohmic resistance - using pulse shaping and timing to reduce polarisation and capacitive effects during measurement phase of overall cycle time
Inventor: RIESE BURKHARD DIPL ING
IPC: G01N27/28
Filed: 1990-01-18
Abstract: A high valve ohmic ressitance (RG) to be measured is arranged in series with a reference resistor (4). Such measurements are standard to the determination of the impedance of a glass membrane electrode (3) immersed in a fluid (7) undergoing pH assessment. The task is complicated by polarisation and system capacity effects - the latter having a marked influence on the shape of voltage pulses used in existing techniques. By using a signal generator (1) and amplifier (2) with novel pulse shaping and timing features together with an auxiliary voltage the necessary measurement cycle is achieved with improved accuracy of pH assessment. ADVANTAGE - Improved accuracy of measurement as result of reduced capacity and polarisation effects.

Patent DE-4025941-A1 (DE)
Inventor: MAIER MARTIN DIPL ING DR
IPC: F02M51/06
Filed: 1990-08-16
Abstract: In prior art fuel-injection valves, a perforated disc with several directional apertures, through which fuel is metered and atomized, is located downstream of the valve seat. These metering apertures produce filament jets with a relatively low degree of atomization, and the fuel/air mixture produced is thus not as homogeneous as it could be. In the invention, the individual metering apertures (43) in the perforated disc (42) are partly covered, for instance by the end (40) of the nozzle body (5). The flow edges (47) thus formed disrupt the fuel flow so that the fuel is particularly finely atomized and will form a homogeneous mixture. The fuel-injection valve proposed is particularly suitable for use in fuel-injection systems in mixture compression spark-ignition engines.
