Abstract: Die Erfindung bezieht sich auf ein Verfahren zum Darstellen von Grauwerten durch Punkte gleicher Größe, deren Anzahl pro Flächeneinheit den jeweiligen Grauwert bestimmt. Zur Vermeidung von senkrecht zur Vorschubrichtung verlaufenden Strichen bei der Wiedergabe gleichmäßiger Grauwerte werden die Punkte in aufeinanderfolgenden Linien (L) um konstante Strecken versetzt gedruckt. Dies erfolgt durch eine Addition von unterschiedlich großen konstanten Werken (K) zu den die Grauwerte darstellenden Summen (SL) von Momentanwerten von Grauwertsignalen (GW). Damit erreichen die Summen (SL) zu unterschiedlichen Zeitpunkten einen Schwellenwert (SW), bei dessen Erreichen jeweils ein Punkt gedruckt wird. Gleichzeitig werden die Summen (SL) um den Schwellenwert (SW) vermindert. Beim Auftreten von Schwarzwerten werden die Summen (SL) vollständig gelöscht.

Abstract: A Josephson current regulator circuit is described for regulating the gate current to a Josephson load device. The regulator circuit is located between the source (V.) of the gate current (I g ) and the Josephson load (Q1), and is comprised of Josephson devices (Jl...Jn) having a critical current (l' mo ) less than the critical current (l mo ) of the Josephson load device. Each of the Josephson regulator devices has at least two states dependent upon the magnitude of the gate current. A resistance (Rl...Rn) is associated with each of the Josephson regulator devices so that, when the state of the Josephson regulator device is changed, resistance is either introduced or removed from the circuit connecting the source and the Josephson load. This adjusts the magnitude of the gate current and maintains within a specified range the ratio of the gate current to the critical current of the Josephson load device.
