    摘要: A circuit for generating a constant reference oscillation from a video signal affected by a time error, comprising, a cut-off stage for receiving the video signal affected by the time error and outputting sync pulses and vertical sync pulses, a first frequency divider connected to the cutoff stage for receiving the vertical sync pulses and outputting divided frequency pulses and a first comparator stage connected to the first frequency divider for receiving the divided frequency pulses. The first comparator stage has an output connected to an oscillator and the oscillator, in turn, has an output connected to a second frequency divider which is also connected to an input of the first comparator stage. A second comparator stage is connected between the cutoff stage sync pulses and an output of the oscillator for producing an output and a clock oscillator is connected to the output and, in turn, is connected to a bucket chain which receives the video signal affected by the time error and outputs a video signal which is free of the time error.

    摘要: A method for making metal powder by atomizing molten metal is improved by causing the solidifying metal droplets to be subjected to a whirling flow of a powdery coolant such as a different powder, e.g. quartz sand or powder separated from the extracted flow of powder just made and cooled additionally. The whirling flow is sustained by blowing an inert gas in up direction into the powder collection chamber.

    摘要: In a playback circuit for a three-line sequential color television signal, which includes a memory presenting four outputs providing, respectively, the undelayed sequential signal and the sequential signal delayed by one, two and three horizontal picture line scanning periods, a combining arrangement connected to the four outputs to combine the signals thereat into a difference signal, and a further combining arrangement for adding the difference signal to the original three-line sequential signal, the circuit is simplified by constructing the memory to cause the signals at its four outputs to have identical amplitudes and by combining the signals at the four outputs of the memory by means of four electrically identical combining components, the undelayed sequential signal and the signal delayed by three picture lines having their polarities reversed relative to the signals delayed by one and two picture lines.

    摘要: A magnetoresistive memory element is provided with a read module having a first pinned layer with a magnetoresistance that is readable by a read current received from an external circuit. A write module has a nanocontact that receives a write current from the external circuit and, in turn, imparts a spin torque to a free layer that functions as a shared storage layer for both the read module and the write module.

    摘要: Mounting method for a miser laser having a miser crystal on the base surface of a housing, which has a side wall with a housing window for the miser exit beam, is provided. A reference beam is directed through the housing window on to the crystal end face of the miser crystal with an inverted light beam direction which the miser beam to be generated is later to have. An adjusting device which permits mutually independent movements, on the one hand in a direction parallel to the reference beam, and on the other hand perpendicular thereto and parallel to the housing base, and also permits rotations about an axis of rotation perpendicular to the housing base, is used to preadjust the premounted miser stack such that the angle between the surface normal of the crystal end face and the reference beam is approximately 45°, and the reference beam strikes the crystal end face approximately at its center. In the as yet not optimally adjusted case, all the reflections are united on a display screen by displacing the miser transverse to the direction of the reference beam and by rotation.
