Title: Asymmetrischer Thyristor und Verfahren zu seiner Herstellung
Inventor: BORCHERT EDGAR DIPL-PHYS
IPC: H01L29/36
Filed: 1986-08-11
Abstract: Ein asymmetrischer Thyristor mit einer n<+>pn<->np<+>-Zonenfolge wird beschrieben, dessen Funktionsweise nicht beeinträchtigt wird und insbesondere dessen Rückwärtssperrkennlinie nicht degradiert wird, wenn er nach Durchlaßbelastung und anschließender Kommutierung vor Ablauf seiner Freiwerdezeit durch die wieder ansteigende positive Spannung zündet. Diese Unempfindlichkeit gegen Zündvorgänge infolge Unterschreitung der Freiwerdezeit wird erreicht durch einen flachen Anstieg der Dotierungskonzentration von der n<->-Zone zur n-Zone, wobei die Dotierungskonzentration in der n-Zone über eine Strecke von mindestens 50 µm annähernd exponentiell ansteigt. Um bei flachem nn<->-Übergang den Vorwärtssperrstrom gering zu halten, werden Dicke und Dotierung der n<->-Zone so bemessen, daß bei der höchsten vorgesehenen Vorwärtssperrspannung die elektrische Feldstärke am pn<->-Übergang etwa 1,5 . 10<5> V/cm beträgt, in der n<->-Zone annährend linear verläuft, und am nn<->-Übergang etwa ¼ des Wertes am pn<->-Übergang beträgt. - Verfahren zur Herstellung dieses Thyristors werden beschrieben.

Abstract: Apparatus and methods are provided for manufacturing a fila­ment wound thermoplastic structure. A filament reinforced ther­moplastic strip is wound about a rotating mandrel to build up multiple layers of the strip about the mandrel and thereby form the structure. As an intermediate portion of the strip is received about the mandrel, that intermediate portion is com­pacted against any underlying layer of the strip by pressing a compacting element against an outer surface of the intermediate portion of the strip. During this compacting process, the inter­mediate portion of the strip and any underlying layer are heated by heating the compacting element. This results in a substan­tially reduced void content in the resulting filament wound ther­moplastic structure.

Abstract: A mounting for changing or laterally reciprocatable inking, damping, or like applicator rolls of a printing press, which rolls are driven by a friction roll in engagement therewith. The changing applicator rolls each have their spindles mounted outside of the roll shell for rotational and axial movement in roller locks. Axial travel is limited by a shoulder ring in the roller lock, the ring cooperating with the outer race of a roller bearing which supports the roll spindle for relative rotational movement within the roller lock. Each roller lock also is mounted so as to be axially locatable in different positions for achieving desired axial movement of the applicator roll, or for preventing spreading movement of the applicator roll entirely.

Abstract: A method is disclosed in which the bare glass fibers are firmly soldered into a solder bath of the splicing device and, after being scored and broken, unsoldered again. To that end, the glass fibers are placed across the solder bath, the solder is heated, and the level of the molten solder is raised above the glass fibers by pressing a slide into the solder trough. The heat supply to the solder bath is subsequently cut off. After the solder has cooled, the glass fibers are firmly fixed therein. To release the fixed glass fibers, the solder is liquefied again. The device for carrying out the method consists essentially of a slotted guide bar, which serves to hold the glass fibers apart, and the solder bath. The latter is a copper block which is thermally insulated from the splicing device and has a projection at one end for attaching a soldering iron.

Abstract: The unit consists of a full-beam headlamp and dipped-beam headlamp. The two reflectors are joined to form a unit. The dipped-beam headlamp essentially consists of an elliptical reflector, a collector lens, a diaphragm and a diffusing lens. All these parts are joined to form a structural unit. In order to be able to arrange the diffusing lens with its body detached from the lens and its frame but such that it can be swivelled together with these parts, there is integrally formed on the full-beam reflector a tube whose front end accepts the diffusing lens. This tube simultaneously envelops the carrier frame of the lens, with the result that the view into the dipped-beam headlamp is screened. <IMAGE>
