Abstract: ABSTRACT          A motor-driven rotating table positioning device has a bullgear engaged by two pinions each driven by the high-efficiency worm and gear set.  These two worm and gear sets are connected by a coupling shaft and an adjustable coupling which allows a desired torsion to be maintained in the coupling shaft thereby eliminating any table backlash caused by the bullgear, pinions and high-efficiency worm and gear sets.  For safety in the event of motor failure, the motor is coupled to the coupling shaft by a low-efficiency or self-locking worm and gear set.

Abstract: ABSTRACT           A speech signal is divided into sections after digitizing and each section is analyzed by the methods of linear prediction to determine the coeffic-ients of a sound formation model filter, a sound volume parameter, information concerning voiced or unvoiced excitation and the period of the vocal band base frequency.  The voiced/unvoiced decision involves rendering only practically absolutely secure deci-sions.  If a decision criterion does not yield a secure decision, the method proceeds to a subsequent criterion and so forth, until a definitely secure decision is possible. Among others, the energy of the speech signal, the number of its zero transitions, the energy of the residual error signal, the autocorre-lation maxima of the residual error signal and trans-verse comparisons of the preceding speech sections are used as the decision criteria.
