Abstract: A clamping ring (122) and temperature regulated platen (110) for clamping a wafer (15) to the platen (110) and regulating the temperature of the wafer (15). The force of the clamping ring (122) against the wafer is produced by the weight of the clamping ring (122) only. A roof shields all but a few contact regions of the interface between the wafer (15) and clamp from receiving depositing particles so that a coating formed on the wafer makes continuous contact with the clamping ring (122) in only a few narrow regions that act as conductive bridges when the depositing layer is conductive.

Abstract: Using a ribbon-suspended meridian gyro, in which the gyro restoring torque is compensated by a countermoment and the countermoment is measured, measurement is performed at a plurality of azimuth angles, a north reference angle being determined from the various measurements. In order to shorten the measuring time, as an individual measurement proceeds the measurement results of the preceding measurements are used in accordance with the effects which the error in the individual measurement has on the northing error to determine an accuracy requirement for the individual measurement in progress. The individual measurement in progress is carried out using said accuracy requirement. In this way, each individual measurement is carried out only with an accuracy which corresponds to the weight of said individual measurement in the total error budget of the northing for the respective north reference angle. A reduction in the accuracy requirements leads to a shortening of the measuring time, because a mean value can be formed over a shorter time interval, for example.

Abstract: A power converting apparatus comprises self-commutated converter (10), fault current restricting device (30), fault detector (61), and cutoff circuit (60). Self-commutated converter (10) converts AC power supplied from an AC power system into DC power and supplying the DC power to a common DC circuit (20), and for converting DC power supplied from the DC circuit (20) into AC power and supplying the AC power to the AC power system. The fault current restricting device (30) is inserted between the self-commutated converter (10) and the DC circuit (20), and includes a diode (31) provided to permit a DC circuit current to flow from the self-commutated converter (10) to the DC circuit (20), and a series circuit having a reactor (32) and a DC power supply (33) and connected in parallel to the diode (31). The fault detector (61) detects a fault current generated when self-commutated converter (10) is short-circuited. When the fault detector (61) detects a short circuit occurring in self-commutated converter (10), the cutoff circuit (60) cuts off power supply to that self-commutated converter (10). With this structure, the DC power supply (33) supplies a circulating current according to a rated current of the self-commutated converter (10) to the reactor (32) and the diode (31).

Abstract: An input video signal is converted into a digital signal by a clock of a predetermined time interval. Of the time base errors included in the above signal, time base errors of the clock unit are corrected by resetting the write address of the memory, and time base errors of less than the clock unit and velocity errors are corrected by an interpolation filter provided at a later stage of the memory. By the above processing, it is possible to correct time base errors by only a clock of a predetermined interval and it is also possible to improve interface characteristics with other digital processing sections.

Abstract: An error correction encoding apparatus (30), for use for example in an optical disc recording and/or reproducing apparatus, comprises a first delay circuit (32) that applies different amounts of delay to respective data words constituting a data block to convert input data in a first array state into a second array state. A first error correction encoder (33) generates first check words from the data in the second array state. A second delay circuit (34) applies different amounts of delay to the data in the second array state and to the first check words to provide data and check words in a third array state. A second error correction encoder (35) generates second check words from the data and check words in the third array state. The amounts of delay applied by the first and second delay circuits (32, 34) are such that the array state of the data in the third array state is the same as the array state of the data in the first array state.

Abstract: A large size cast monolithic refractory module having high dimensional stability, good compressive loading, and good thermal shock resistance in the range of -20° to 1565° Celsius, which module may be used in the repair of the coke oven, and also a process for making such a large size cast module. The large size cast module should be of a size sufficiently large that it can replace all those silica bricks used in a course of bricks to enclose a single flue in a heating wall of a coke oven. A minimum size has a width of at least 35 centimetres, a height of at least 13.5 centimetres, and a length of at least 35 centimetres. The process for making such a module includes the steps of selecting a material which when cast will have the desired characteristics, mixing the dry refractory material with a relatively small amount of water, pouring it into a mold on a shaker table and vibrating the mold when filled, and then by firing the cast material after initial set at progressively higher temperatures up to 425° Celsius over a period of almost 60 hours.

Abstract: Beschrieben ist ein Verfahren zur Wandlung eines Analogsignals in ein Digitalsignal, nämlich einer analogen Eingangsspannung (in Form einer vorzugsweise niederfrequenten Rechteckspannung) in ein der Eingangsspannung proportionales digitales Ausgangssignal, bei dem die Eingangsspannung während einer vorgegebenen Aufintegrationszeit auf eine Integratorspannung aufintegriert wird, nach Ablauf der Aufintegrationszeit die Integratorspannung während einer Abintegrationszeit durch eine Referenzspannung auf Null abintegriert wird und aus im Verhältnis von Abintegrationszeit zu Aufintegrationszeit, multipliziert mit der Referenzspannung die Eingangsspannung bestimmt wird. Dadurch, daß erfindungsgemäß während der Aufintegrationszeit der Eingangsspannung - vorzugsweise aus der Referenzspannung abgeleitete - Aussteuerimpulse überlagert werden und damit die Integratorspannung beeinflußt wird, wird erreicht, daß man zu einer vorgegebenen Integratorspannung kommt, unabhängig von der Eingangsspannung.

Abstract: A frequency synthesizer comprises a voltage controlled oscillator, and a variable frequency divider for dividing the VCO frequency according to the frequency of a communication channel. The output of frequency divider is compared with a reference frequency and a phase difference of first polarity and a phase difference of second polarity are detected. A charge-control voltage is generated with a duration variable with the phase difference of first polarity and a discharge-control voltage with a duration variable with the phase difference of second polarity, First and second integrators are coupled respectively to outputs of the phase comparator for respectively smoothing waveforms of the control voltages. Energy is injected into a charge pump in response to the smoothed charge-control voltage and drained from it in response to the smoothed discharge-control voltage to produce a frequency control signal for coupling to the VCO. To achieve instant switching between adjacent channels, a differentiator is coupled across the outputs of the phase comparator for preserving part of energy to be supplied to or drained from the charge pump until sufficient energy is stored.

Abstract: Stations (T) on a faulty token ring which includes a control adapter (16) are removed one at a time starting with the most down stream station from the control adapter or if a station up stream from the last station is known to be good, all of the stations down stream from that station are removed and the one at a time removal starts with the known good station. The control adapter transmits special beacon frames during the station removal process and when the removal of a station results in receipt of the special beacon frame at the control adapter, the control program identifies a fault domain which includes the station whose removal caused the special beacon to be received at the control adapter and the station immediately up stream from that station. The stations in the fault domain are selectively subjected tests and removed from the ring when a failure is detected.
