Abstract: A coagulator for an exhaust purification device of internal-combustion engines has an electrode (11), guided through into a housing (10) in an insulating manner, for generating an electrostatic field. The electrode (11) is in this case supported via at least one insulator (13) on the housing (10). To prevent the formation of a short-circuit link between the electrode (11) and the housing (10) by the precipitation of so-called agglomerates on the surface of the insulator, the insulator (13) is heated to a surface temperature of over 400 DEG C. In order to achieve an extremely small construction of the insulator (13) and a low energy requirement for its heating, the insulator (13) is of disc-shaped design and has a heating channel (30) which is arranged internally, as a spiral, and through which hot gases flow. The said hot gases are tapped off a partial flow of the exhaust gas from the internal-combustion engine, or are extracted from the exhaust gas of a soot burner. …<IMAGE>…

Abstract: This is a new equipment for the drying of water dispersion glue (with polyurethane, neoprene and natural or synthetic rubber base, both mono and bi-components), after the said glue has been spread on the uppers and/or soles: it can be integrated with other processes, and in particular, with carding, spreading and reactivation (heating phase of the supports in order to them press). 
     This equipment consists of a modular system composed of one or more chambers, inside which some uppers and/or soles are placed on supports; decompression is then created thus allowing controlled and rapid evaporation and consequently the glue is dried. The temperature can be fixed beforehand and increased by a source of heat.

Abstract: The invention relates to an apparatus for the mixing or loosening up and the dosed delivery of loose or lightly cohesive material, such as fodder, which apparatus comprises: 
    a container, for example a supply bunker for the temporary holding of the material, which container narrows in a downwards direction, 
    one or more rotationally drivable agitator present inside the container, and 
    one or more delivery device connected to the underside of the container for the dosed delivery of the material. 
     Now the invention has for its aim to provide an apparatus of the kind stated above, which is inexpensive and is also highly reliable even in the long term, and which is capable of causing the delivery of the loose or lightly-­cohesive material to make place with a high level of accuracy, while the apparatus can work fully automatically. 
     The invention has further for its aim to provide an apparatus whereby an animal to be fed can consume its fodder for the entire duration of the feeding period without disturbance from other animals. 
     To realize the above aims, the invention proposes embodying an apparatus of the kind described in such manner that: 
    the container has everywhere the same cross section with respect to a horizontal line, 
    the bottom zone of the container has the form of part of a cylinder, 
    the agitator has an axle whereof the centre line at least approximately coincides with the centre line of the said part of the cylinder, and 
    the axle of the agitator supports vanes, the vanes of adjacent groups having opposite angular dispositions, for example such that in conjunction with the rotation direction of the axle they impel the material present in the container in the direction of the imaginary vertical plane in which a delivery device is situated. In this manner an excellent equalization of the material in the container takes place, moreover consuming little energy.

Abstract: A Schottky barrier diode includes an extra implanted N-type region (24;34) at the surface of the epitaxial layer to increase the impurity concentration there to about 1x10¹⁹ atoms per cubic centimeter. In a method of fabricating one such diode, arsenic is employed to overcompensate a guard ring (20) where the Schottky diode is to be formed, but in fabricating another such diode phosphorus is employed and the guard ring is not overcompensated. The resulting Schottky diodes, when employed in the static random access memory cells, dramatically increase the alpha particle resistance of such cells, while also substantially decreasing the access time.

Abstract: A system for real-time digital processing of a video signal is disclosed. Using a large number of one-bit serial processor elements (10), each operating on one pixel of a horizontal scan. The video signal (15) is converted to digital by an A-to-D converter (18), and stored in a set of input registers, one register for each processor element (10). All of these input registers are loaded during a horizontal scan, as the input registers are addressed in sequence by a commutator. Each processor element (10) includes a one-bit binary adder, a set of one-bit registers, and two one-bit wide data memories of a size to store data from several scans. The processor elements are all controlled in common by a sequencer, a state machine or a processor (25). The processed video data is transferred to an output register for each processor element (10), from which it is converted to a video signal by a D-to-A converter (0). A frame memory (17) may be used to save a processed frame for use in convolving the next frame; the input of the frame memory (17) is taken at the output registers, and the frame C memory output is applied to the input registers.

Abstract: Fast power diode and a process for manufacturing it. The recovery behaviour of fast power diodes having psn structure is essentially determined by the doping and dimensioning of the high-resistance central zone. Such diodes do not, however, fulfil all the requirements imposed on operation in conjunction with switchable semiconductor devices. As a result of a modified construction of the p<+>-type emitter zone, the fast diode according to the invention has an optimum recovery behaviour and can be used even when increased requirements are imposed as a free-wheeling diode in various power-electronics circuits. The new process makes it possible to produce a psn structure having the required recovery behaviour in a simple manner using conventional steps. In the new diode, the p<+>-type emitter zone is of appreciably thinner construction and its dopant concentration is 10<17> to 5x10<18> atoms/cm<-3>, which is 10<3> to 10<4> atoms/cm<-3> less than that of the n<+>-type outer zone. The latter is additionally provided with an n<++>-type surface zone. According to the process, the n<+>-type zone and the p<+>-type emitter zone are first produced on the central zone, then the n<++>-type surface zone is formed and heavy metal atoms are introduced on the p-type emitter side. <IMAGE>

Abstract: A method and device for generating ion beams with a large beam cross-section are described. An ion beam, which is used for dry etching during production of microelectronic components, must have a high beam quality (small divergence, few impurities, high current density). In the case of known large-area ion beam sources, the ions are extracted from the plasma with the aid of grids. Because of the field pattern at the grid points, the use of the grid has a disturbing effect on the beam quality. The method according to the invention has no grid at all, the ions being accelerated with the aid of metal cylinders. In this case, a pulsed generation of ions and a pulsed acceleration ensures that the ions can be accelerated by fields only when they are moving in regions in which the field is virtually homogeneous. As a result of the high beam quality achieved in this manner, the ion beam is suitable for the production of very small structures in the sub-micrometer region. <IMAGE>

Abstract: A system provides for the testing of components which connect to one or more of programmable logic devices (PLDs), each of which is organized in a predetermined manner. Each PLD includes a plurality of programmable logic sections, each of which connect to I/O pins through driver and receiver circuits. An available section includes programmed means for causing its driver circuit to force the I/O pin to a first logic level when made operational. The other sections each include programmed means for connecting their associated driver circuits to be controlled by signals applied to the receiver circuit of the available section. During testing, means are externally applied to the I/O pin of the available section which drive the pin from the first logic level to a second logic level. This causes the receiver circuit to apply signals which inhibit the driver circuits of the remaining sections from applying signals to their I/O pins thereby enabling the testing of components which connect to these I/O pins without interference.
