Abstract: METHOD AND APPARATUS FOR CODING DIGITAL SIGNALS     Abstract of the Disclosure In a method and apparatus for coding of digital signals, especially so-called "waveform" coding of voice frequency signals to reduce bit rates for reduced transmission or storage requirements, in which, for each block, an excitation signal is derived which, when applied to a synthesis filter having suitable LPC coefficients, will generate an approximation to the input signal, low signal delay is achieved by deriving such excitation signal using the LPC coefficients corresponding to the last sample period of the corresponding block.  Thus the excitation signal calculations in the encoder need only be delayed by the duration of the block, which is shorter than the delay incurred by previous proposals.  The LPC coefficients can be derived on a continuous or sample-by-sample basis using an adaptive lattice.  Simplified computation of the excitation signal, which comprises a set of pulses fewer in number than the number of samples in the original block, may be achieved by cross-correlating the impulse response of the modified synthesis filter with the output of the filter and using the result, together with the covariance of the impulse response, to derive the parameters of the excitation pulses.          Further computation simplifications may be achieved by using an auto-correlation as the covariance signal.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE         A coherent phase shift keyed demodulator provides demodulation of a base band data message through the use of a reference vector signal generator which employs an inter-mediate reference vector generated from the phase of an in-coming carrier signal which, under certain conditions, is reversed in phase prior to being combined with a previous value of the reference vector to generate an updated reference vector signal. The demodulator incorporates a polarity sampler, an image signal generator and a zero crossing detector asso-ciated with a phase angle vector generator.  A summation vector generator receives a signal from the phase angle vector generator and, in turn, provides signals to a phase detector and a reference vector generator.  The demodulator also includes apparatus to perform concurrent carrier detection and bit synchronization operations.

Abstract: ABSTRACT          TURNING MECHANISM OPERATING ALTERNATELY IN          OPPOSITE DIRECTIONS TO FACILITATE THE DRIVING          IN OR EXTRACTING OF PILES       The invention relates to a turning mechanism for driving in or extracting piles tangential rotary blows being imparted by a rocker arm equipped with balance weights and arranged in rotary manner relative to the pile.          In order to render superfluous the hitherto necessary  noise-damping, additional damping means, damping members made from an incompressible, elastic material are used, which are placed in recesses in at least one stop of a pair of stops in such a way that there is a deformations, particularly at right angles to the impact direction, which is within the elastic limit of the member and prevents direct contact between the stop pairs. These members are arranged on all parts of the rocker arm which, in operation, form noise sources. As a result of this arrangement and construction of the incompressible, elastic members, the working noise of the turning mechanism is reduced to such an extent that it falls within the limits for residential areas, without requiring the hitherto necessary, additional damping means.

Abstract: Abstract of the Disclosure A speech recognition method and apparatus employ a speech processing circuitry for repetitively deriving from a speech input, at a frame repetition rate, a plurality of acoustic parameters.  The acoustic parameters represent  he speech input signal for a frame time.  A plurality of template matching and cost processing circuitries are connected to a system bus, along with the speech processing circuitry, for determining, or identifying, the speech units in the input speech, by comparing the acoustic parameters with stored template patterns.  The apparatus can be expanded by adding more template matching and cost processing circuitry to the bus thereby increasing the speech recognition capacity of the apparatus.  The template matching and cost processing circuitries provide distributed processing, on demand, of the acoustic parameters for generating through a dynamic programming technique the recognition decision.  Grammar graphs, having a plurality of nodes, are employed for representing both sequences of speech keywords and the speech components which form a keyword.  The grammar graphs are software interchangeable, and can be advantageously employed together with dynamic programming methods.

Abstract: ABSTRACT OF THE DISCLOSURE         A stream of high-speed bipolar signals transmitted along standard twisted pair telephone wiring are detected by a circuit that includes a pair of differential amplifiers each having a signal input connected directly to one conductor of the twisted pair and a reference input connected through a peak voltage detector to the opposite conductor.          The amplifiers function as an input signal comparator which generates a corresponding bit stream of logical ones in response to the bipolar signals that exceed 50% of the average peak voltage input.  A threshold bias voltage corresponding to positive going signals on each conductor is generated by the detector and charges separate capacitors that connect each reference input to its conductor.  The bias voltage and bipolar signals input to each amplifier are algebraically summed which doubles the differential input signal and results in an increased signal to noise ratio of about six decibels.

Abstract: Abstract of the Disclosure A Wide band high voltage and high power amplifier is particularly useful for telephony applications.  The amplifier employs a flyback converter with the capacitor storage element coupled across the line.  The subscriber line is characterized in having a definite load impedance which impedance is in parallel with the storage capacitor of the flyback converter.  The subscriber lines are monitored by a differential amplifier which provides a single-ended output indicative of the levels across the lines.  This output is summed with the input signal to develop an error signal.  The input signal to the line circuit is the particular signal of conern such as ringing, the voice signal and so on.  The error signal is supplied as one input to a comparator having another input coupled to a triangular reference waveform.  The output of the comparator provides a pulse width modulated waveform where the width of the pulses are indicative of the error signal.  These pulses are applied to a transistor coupled to the primary winding of the transfromer associated with the flyback converter to enable flyback operation during the pulse and hence to transfer energy to the storage capacitor as a function of the error signal.

Abstract: ABSTRACT OF THE DISCLOSURE Novel single crystals of a compound semiconductor of Groups III-V with a low dislocation density are provided herein.  More than two impurities are doped in a host crystal of compound semiconductors.  One of the impurities is an anisoelectronic impurity.  One impurity, or more than one impurities are isoelectronic impurities.  The anisoelectronic impurity determines the electronic property and the carrier density of the semiconductor.  The isoelectronic impurity does not change the electronic property, but it has an effect of impurity hardening.          The impurity atom forms a covalent bond with a host atom.  The bond length between an impurity and a host atom differs from the standard bond between host atoms.  Although the real bond lengths between an impurity atom and a host atom cannot be measured, the difference of bond lengths generate dislocation or other lattice defects of crystal.  The real bond length "A" between an impurity and a host atom in an impurity-doped crystal may be surmised from the corresponding bond length "a" or "b" in a two-component crystal consisting of the impurity element and the host element.          Definite and measurable bond lengths "a" or "b" replace the real unknown bond length "A".  The impurity whose replaced bond length "a" or "b" is larger than the standard bond length "a0" between host atoms is called an over-impurity.  The impurity whose replaced bond length "a" or "b" is smaller than "a0" is called an under-impurity.  At least one under-impurity and at least one over-impurity must be doped.  The arithmetic average "a" of the Abstract of the Disclosure (page 2) bond lengths between the impurity atoms and the host atoms should not differ from "a?" by more than 1%.  Size effects of under- and over-impurities compensate each other in the double-impurity-doped crystal.  Dislocations or other lattice defects are reduced.
