    • The room temperature-curable polymeric composition is prepared by admixing (a) a polyether terminated at both molecular chain ends each with a mercapto group with (b) a 3-methacryloxypropyl silane having at least two hydrolyzable groups, e.g. alkoxy groups, in a molecule and (c) a 1,1,3,3-tetramethyl guanidino-containing organosilicon compound. The component (b) first reacts with the mercapto group of the component (a) to introduce silicon-bonded hydrolyzable groups to the molecular chain ends of the polyether and the silicon-bonded hydrolyzable groups pertain to the crosslinking reaction with the atmospheric moisture. The composition has good storability and workability and is capable of giving a cured rubbery elastomer without the addition of a toxic lead compound as a curing catalyst which is indispensable in the conventional polyether-based room temperature-curable polymeric compositions.

    • A pitch period extracting apparatus includes a microcomputer which determines a sampling frequency for an A/D converter, and a range of delay times for calculating autocorrelative values on the basis of the sampling frequency. For example, the delay times are set within a range of 20 samples≦k≦100 samples in a case of 8 kHz, and a range of 15 samples≦k≦75 samples in a case of 6 kHz. The microcomputer calculates the autocorrelative values of speech signal data stored in a buffer memory, and outputs a delay time at which a maximum autocorrelative value is obtainable as a pitch period of an inputted speech signal.
