Abstract: ABSTRACT      In such electrical components as, for example, high-blocking-resistance thyristors, high-frequency thyristors and rapid-action diodes, it is desirable to ensure that the concentration curve for recombination centres in the axial direction of the semiconductor body of the component follows a predetermined course.  For this purpose, at the anode side surface of the body elements are provided having respectively a higher and a lower gettering action on the recombination centres. By adjusting the surface areas  of the respective elements, a desired concentration drop in the central region of the body in the axial direction can be set up.

Abstract: Abstract of the Disclosure A manipulator apparatus having a manipulator arm movable in a plurality of axes is programmed to perform a desired sequence of operations over a desired path.  The programming is accomplished by an operator manually moving the end of the manipulator arm over the desired path while encoders associated with each axis of the manipulator appa-ratus produce signals representing movement of the arm in each of the axes.  The encoder signals are automatically recorded at predetermined increments of movement of the arm as command signals for controlling movement of the arm during a playback cycle.  Recording of these command signals is con-trolled by a guide wheel which is positioned on the end of the arm during programming and is rotated by maintaining the wheel in contact with the work as the operator moves the manipulator arm over the desired path.  Control pulses are generated for each predetermined increment of rotation of the guide wheel and these control pulses are employed to control recording of the encoder output signals.  Weld cycle controls, weld speed controls and a manual record control are provided.  The manual record control is actuated to record positions between welds wherein the end effector is moved between weld paths without the guide apparatus being in con-tact with the welding work surfaces.  During programming, guide strips having tracks into which the guide apparatus is placed, may be positioned along the desired weld path by the operator.  The recorded signals corresponding to the distances the arm is to be moved in each of said axes are utilized during a playback cycle to control drive apparatus for each axis, such as stepping motors, which are de-energized during the programming phase.  During playback a welding tip -i-or other implement is positioned in place of the guide wheel apparatus whereby the manipulator performs the desired operation over the programmed path at a predetermined, selectable speed independent of the programming speed.  The recorded command signals are effective to drive pulse gener-ation circuitry during playback to produce pulse trains that are supplied to the stepping motors so that they are moved at the required velocities to perform a weld over the pro-grammed path.                             -ii-

Abstract: SWEEP CIRCUIT FOR CATHODE-RAY TUBE DISPLAY         ABSTRACT              A recurrent digital sweep signal starts an integrator fed by a constant current.  The integrator includes push-pull Darlington stages, which act as alternately conducting controlled current sources for split deflection coils outside the integrator feedback loop.  A phase shifter provides arcsine correction.  A time-out circuit avoids excessive dissipation if the sweep signal should be lost.

Abstract: ACTIVE FILTER                 Abstract of the Disclosure The high power (10-1000 W) modulated carrier of a noisy transmitter is attenuated and amplitude limited and is used to control a power oscillator which regenerates the carrier and modulations without the loss of power.  The power oscillator is slaved in frequency to the amplitude limited and attenuated signal and it follows any phase or frequency modulation present thereon.  Noise components appearing on the original carrier fall outside of the information passband of the power oscillator loop and therefore are not reproduced.  The noise free output from the power oscillator is then A.M. modulated prior to power amplification and transmission.  The oscillator operates at relatively high power (1 watt) and is automatically digitally coarse tuned and analog fine tuned.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to reading while writing on an information storage videodisc.  Prior art techniques of recording on videodiscs have involved processing procedures producing recorded intelligence information on a disc directly from a corresponding intelligence signal in amplitude varying with time format.  Such  procedures have definite limitations as to the quality of the reproduced signal.  Additionally, it has previously not been possible to instantaneously read and check the recorded signal.  In accordance with the present invention, a writing system includes an apparatus for recording information on a videodisc having a light responsive coating covering the videodisc sub-strate for retaining indicia representing a frequency modulated information signal.  A light beam of sufficient intensity is provided to interact with the responsive coating of the videodisc forming the indicia representing the information signal.  A reading system is provided and includes a reading beam directed along an optical path between a reading light source and the videodisc. The reading beam is of sufficient intensity to generate reflections from the indicia on the videodisc.  A light-sensor is responsive to the reflections for gener-ating a frequency modulated signal having its information content in the form of a carrier frequency which has frequency changes with time.  The reading while writing apparatus and method provides a comparative system for analyzing the initial frequency modulated signals used in writing on the videodisc to the actual frequency m odulated signal produced in reading the videodisc.
