Abstract: Abstract A digitized speech signal is divided into sections and each section is analyzed by the linear prediction method to determine the coefficients of a sound formation model, a sound volume parameter, in-formation concerning voiced or unvoiced excitation on and the period of the vocal band base frequency.  In order to improve the quality of speech without increasing the data rate, redundance reducing coding of the speech parameters is effected.  The coding of the speech parameters is performed in blocks of two or three adjacent speech sections.  The parameters of the first speech section are coded in a complete form, and those of the other speech sections in a differential form or in part not at all.  The average number of bits required per speech section is reduced to compen-sate for the increased section rats, so that the over-all data rate is not increased.

Abstract: S P E C I F I C A T I O N     TITLE:  A TWO STAGE A-TO-D CONVERTER      INVENTOR:  PETER R. HOLLOWAY     ABSTRACT OF THE DISCLOSURE     A two-stage analog-to-digital converter wherein the first stage is a resistor-string d-to-a converter controlled by a successive-approximation register, functioning in a first phase of the conversion operation to determine a set of higher order bits of the digital output signal.  The second stage is a dual-slope integrating-type a-to-d converter functioning in a second phase of the conversion operation to determine the remain-ing lower-order bits of the digital output signal.  The dual-slope converter receives a reference signal derived from two adjacent junction points of the first-stage resistor-string d-to-a converter corresponding to the higher order bits determined in the first phase of operation, thereby to assure high resolu-tion performance.

The precipitated silicas are pro-duced by a process in which sodium tetrasilicate solution and sulphuric acid are simultaneously fed into water heated to a temperature of 40 to 42°C while keeping a pH value con-stant in the range of 6 to 7 and while shearing continuously over the entire precipitating time with an Ekato turbine and by interrupting the precipitation for 90 minutes from the 13th to the 103rd minute, whereupon a final silica concentra-tion of 46 g per litre is obtained after a total precipitat-ing time of 146 minutes, the precipitated silica is aged for 12-17 hours, the precipitated silica is separated from the suspension with a filter press and washed and the filter cake is liquefied with water and/or acid to a suspension con-taining 10 to 16% by weight of solids and then washed and ground with a cross current mill or jet mill or not ground at all.

Abstract: ABSTRACT OF THE DISCLOSURE    An air/fuel ratio monitoring system in an IC engine, using an oxygen sensor of the concentration cell type which has a laminate of an inner electrode layer, a microscopically porous layer of oxygen ion conductive solid electrolyte and an outer electrode layer exposable to the exhaust gas and exhibits a sharp change in the level of its output voltage in response to a change in the air/fuel ratio in the engine across a stoichiometric ratio.  To ensure accurate monitoring of the air/fuel ratio even when the engine is operated under such conditions as cause a great rise or fall in an average level of the output of the oxygen sensor, the monitoring system has signal treatment means for producing a variable reference voltage, with which the sensor output is compared, by first adding a definite voltage to or subtracting a definite voltage from the output of the oxygen sensor depending on the result of comparison between the sensor output and the reference voltage and then smoothing the voltage resulting from the addition or subtraction of the definite voltage.

Abstract: Abstract:        The present invention relates to a process used in the manufacture of CMOS integrated circuits.  The process involves the steps of forming in a silicon wafer, contiguous surface regions of opposite conductivity types.  The process involves the forming of islands of composite layers of silicon nitride and silicon oxide over various portions of the surface regions. The process further includes the step of implanting boron selectively into the surface regions of both conductivity types not covered by the islands and covering the p-type surface regions with an implantation mask.  Ions are then implanted from the group consisting of arsenic and phosporous selectively into the n-type surface regions not covered by the ions, the dosage being substantially the same for both implantations.  The implantation mask is then removed from the p-type surface regions.  The wafer is then heated in an oxidizing atmosphere for oxidizing the surface regions not covered by ions and forming under the oxidized regions p-type chanstops in the p-type surface regions and n-type chanstops in the n-type surface regions.  The islands are then removed.  The final step of the process involves forming n-type MOS transistors in the p-type surface regions and p-type MOS transistors in the n type surface regions previously covered by islands.
