Patent DE-19857823-A1 (DE)
Title: Optimieren der elektrophotographischen Entwicklung von Rändern
Inventor: THOMPSON JOHN A
IPC: G03G15/06
Filed: 1998-12-15
Abstract: Die Entwicklung der Ränder von entladenen Bereichen auf einer Photoleitertrommel in einem elektrophotographischen Drucksystem wird durch das Verhältnis der Gleichkomponente der Entwicklervorspannung zu dem Betrag der Differenz zwischen der Gleichkomponente der Entwicklervorspannung und der Gleichkomponente der Vorspannung gesteuert, die der Photoleiterladerolle zugeführt wird. Ein Entwicklungssystem, das einen Entwickler, eine Photoleiterladerolle, eine Hochspannungsleistungsversorgung, einen Sensor für eine optische Dichte und eine Steuerung zum Steuern der Hochspannungsleistungsversorgung aufweist, optimiert die elektrophotographische Entwicklung von Rädern. Der Sensor für die optische Dichte wird in einem Kalibrationsverfahren verwendet, um den Wert der Gleichkomponente der Entwicklervorspannung zu bestimmen, die notwendig ist, um sicherzustellen, daß die optische Dichte von entwickelten Bereichen die minimal spezifizierte optische Dichte erfüllen wird. Eine Optimierung der Ränderentwicklung wird erreicht, indem die Hochspannungsleistungsversorgung so gesteuert wird, daß die Differenz zwischen der Gleichkomponente der Entwicklervorspannung und der Gleichkomponente der Photoleitervorspannung auf einem im wesentlichen konstanten Wert gehalten wird, wenn die Gleichkomponente der Entwicklervorspannung in aufeinanderfolgenden Kalibrationen eingestellt wird.

Title: Injection nozzle assembly for molding two-component resin, comprises nozzle and mold feed bush, with mating curvatures and conicity assuring leak-tight seal
Inventor: KEMPER JOSEF
IPC: B29C67/24
Filed: 1999-03-15
Abstract: The nozzle assembly (16) includes a nozzle (30) on the mixing-head side, and a feed bush (34) on the mold side.

Title: Verfahren und Schaltungsanordnung zur Konzentration von analogen Signalen zu einem digitalen Datenstrom in einem Breitbandübertragungssystem
Inventor: KRIMMEL HEINZ
IPC: H04J3/04
Filed: 1999-03-19
Abstract: In modernen Breitbandübertragungssystemen, die Übertragungsstrecken aus Koaxialkabeln und Lichtwellenleitern enthalten, sog. Hybrid Fiber Coax Networks, ist es erforderlich, zur Verkehrskonzentration Signale und Datenströme zusammenzufassen, um die Kapazitäten der Übertragungswege besser ausnutzen zu können. Dazu ist es bekannt, Signale im analogen Bereich zu addieren und dazu die Addierer hierarchisch zu organisieren. Für die zur Signaldegradationsreduktion digitalisierten Verarbeitung wird, um die Probleme bei der Synchronisation zu umgehen, eine A/D-Wandler-Addierer-Kombination als Grundschaltung beschrieben, die zu einer Kettenschaltung zusammengeschaltet werden kann, wobei der Abtasttakt und das Synchronisiersignal jeweils aus der am Ausgang der vorangehenden Grundschaltung zur Verfügung stehenden Summe aus Datenströmen abgeleitet wird, so daß sich das Synchronisiersignal von Grundschaltung zu Grundschaltung innerhalb der Kette fortpflanzt und sich somit die Anforderungen an die Synchronisierung der Datenströme im Vergleich zum Stand der Technik wesentlich verringern.
