Abstract: Described is an improved fabrication process for vertical DMOS cells contemplating the prior definition of the gate areas by placing a polycrystalline silicon gate electrode and utilizing the gate electrode itself as a mask for implanting and diffusing the body regions, while forming the short region is carried out using self-­alignment techniques which permit an easy control of the lateral extention of the region itself. A noncritical mask defines the zone where the short circuiting contact between the source electrode and the source and body regions in the middle of the DMOS cell will be made, allowing also to form the source region. Opening of the relative contact is also effected by self alignment tech­nique, further simplifying the process.

Abstract: Granules based on alkaline earth metal carbonates often contain unwanted organic additives or alkaline earth metal hydroxides. In the novel granules, the weight percentage of non-carbonate impurities is < 5 %. The basic effect can be easily buffered, and the granules can be easily converted back into the original particle size with little mechanical effort. The binder is an alkaline earth metal carbonate recarbonatised from alkaline earth metal hydroxide. Recarbonatisation can preferably take place with the addition of water and reaction with gaseous CO2 in a fluidised bed in which the bed is set to such a height that the rate of the reaction with CO2 is greater than the drying rate of the bed. The granules can be used as component of a feeding stuff.

Abstract: A method for the detection of a substance which is present in aqueous solution and which is made, by an enzyme attached to a carrier substrate, to undergo an enzymatic redox reaction by means of an electron acceptor/donor complex which, after the redox reaction has taken place, reacts with a chromogen to give a dye is to be improved by allowing gaseous pollutants also to be detected. The choice of suitable enzymes should, because of their "key/lock coding", make a sensitive detection method which is specific for the type of gas possible even when the pollutant concentration is low. This is achieved by a) initially contacting the enzyme on the substrate carrier with an aqueous reagent solution which contains the complex and the chromogen, and subsequently b) contacting the air sample with the reagent solution to transfer the pollutant from the gas phase to the liquid phase. <IMAGE>

Abstract: A thermal imager having an array of sprite detectors is provided with a novel means for reducing or eliminating lininess in the reproduced image. This means comprises a low pass optical filter which cuts out wavelengths above 11.5 microns and adjustable gain buffer amplifiers in the respective channels. It is found that with the use of the optical filter the gains of the buffer amplifiers may be preset, when setting up the apparatus, to eliminate lininess and it is not necessary to include complex and noisy circuitry for continuously monitoring the signals output by the detectors and then applying appropriate corrections to the individual channels during operation of the apparatus, as in the prior art.

This arrangement results in load-angle regulation which allows the motor always to be operated at the maximum possible motor torque, throughout the stepper motor frequency range. In consequence, improved motor dynamics are possible, the stepper motor can no longer unlock and a significantly better power balance is also achieved.

Abstract: A water soluble factor is derived from regenerating nerves, such as the optical nerves of fish, and this factor activates suitable target cells, such as for example glial cells, to produce extracellular proteins. Mainly laminin is thus produced. The factor is a negatively charged protein which has an apparent molecular weight of about 10,000 daltons, determined on a sieving type column. There is also provided a process for the purification of such factor. Furthermore there are provided pharmaceutical compositions which induce regeneration of nerves of the central nervous system of mammals, which contain as actaive ingredient an effective quantity of such purified facator. The effect of this factor on the regeneration of nerves is augmented when the injured site is irradiated with radiation from a low energy He-Ne laser.

Abstract: In order to simplify the process-related treatment of textiles, such as fabrics or knitted fabrics as well as textile-type material, individual short textile webs (21-24) are joined at their ends (31) to form a single long textile web (2) and subjected to a process-related treatment in continuous operation, then folded in batches of the shorter textile webs and placed, loosely joined, in partial stacks (7, 71, 72, ...). The long textile web (2) can be subjected as a whole immediately or after intermediate storage to a further continuous treatment and can be divided up again if required. In this manner, the expenditure for changeover or renewed introduction in the case of textile webs (21-24) during the duration of the function of a certain process-related treatment is largely avoided. Carrying out the method can be simplified by an apparatus for folding and piling, a detector (33) being provided closely adjacent to the textile web (21-24) at a given distance from the piling apparatus (6), which detector detects the joining places (37) or detects signal elements (32) worked into the textile web (21-24) at a certain distance from said joining places and then controls the formation of folding piles (7, 71, 72) and their removal. <IMAGE>

Each confirmation message is then correlated with the stored indications of electronic mail objects within the confirmation log. Thereafter, the sender may display the contents of the confirmation log selectively by mail object or recipient to determine the status of multiple selected electronic mail objects. A notification of the receipt of a confirmation message may also be transmitted to the sender.
