Patent DE-2906200-A1 (DE)
Inventor: JANAK MILOSLAV DIPL ING
IPC: G11B5/09
Filed: 1979-02-17
Abstract: During the reading of serial data signals, for example, from a so-termed magnetic floppy disc, a synchronized condition between the local oscillator of the reading device and the timing of the data stream must be reached as quickly as possible after the start of the read operation. When the initial synchronization has been reached, readjustment of phase and frequency may take place only slowly, because the instants at which the actual signal transitions occur may exhibit a large spread with respect to the nominal instants. Therefore, during a synchronization operation an element of a read clock pulse train is applied to the phase comparator at each status transition of the medium as well as at further instants. The data sample signal of the clock pulse generator is applied at twice the bit frequency to the other input of the phase comparator. As a result, during the synchronization operation the phase comparison is performed in a dense series, so that the low-pass filter connected to the output of the phase comparator may have a high cut-off frequency. Once the synchronization has been realized, the phase comparison is performed only once per data bit and, the low-pass filter is switched over to a lower cut-off frequency.

Filed: 1979-07-23
Abstract: An automated opto-electronic test system for quality control of two-dimensional elements with high geometric figure density, such as printed circuits, intermediate printed circuit products, and printing tools has a semiconductor image sensor disposed above a compound table having a position sensor which moves the test specimen beneath a lens in a meandering path at a velocity which is known relative to the semiconductor image sensor. The signals from the image sensor are first analyzed in an analog signal pre-precessor to which are connected a number of error recognition circuits operating in parallel each of which produces an error report which is transmitted to an error coordinating circuit. The error reports are therein associated with position coordinates on the test specimen which are supplied by the position sensor of the compound table and stored until a complete scan of the test specimen has been undertaken and are subsequently employed to move the test specimen to the positions at which the errors occur for visual examination such as by magnification. If the test specimen is a printed circuit, tests which are undertaken are a minimum geometry test measuring respective track and insulation widths, a solder eye test and a special geometry test for open and short circuits.

Title: Method for controlling and regulating a synchronous machine supplied from a converter
Inventor: BECK HANS-PETER DIPL ING
IPC: H02P25/03
Filed: 1981-03-24
Abstract: The control and regulation of a synchronous machine by means of a thyristor converter, the rotor displacement angle being measured and a desired speed being compared with the actual speed, is intended to be carried out such that the tendency of the state variables to oscillate when the torque emitted by the machine corresponds to the desired value is overcome. This is achieved by the rotor displacement angle displacement taking place as a function of the real and reactive current, in that these values are additionally supplied to the control set for the thyristors, a DC voltage supplying the invertor being displaced over a characteristic, as a function of the desired speed value. <IMAGE>
