Abstract: PURPOSE:To estimate the titled strength in high accuracy in a simple operation, by combining the compounding effect estimated by assuming multi-description compounded coal as an assembly of the combination of two-description compounded coals and the added value derived from the strength value for the coke produced by dry distillation singly of each coal multiplied by compounding rate. CONSTITUTION:In estimating hot reaction after-strength (CSR) of the coke produced by dry distillation of multi-description compounded coal, the compounding effect estimated by assuming multi-description compounded coal as an assembly of the combination of two-description compounded coals and the added CSR value calculated from the CSR value for the coke produced by dry distillation singly of each coal multiplied by compounding rate are combined, thus accomplishing the objective estimation. Said compounding effect can be obtained by using (1) the degree of superposition calculated from superposition of the softening melt zone for the two kinds of coal in the coal melt curve derived during fluidity measurement for the respective coals by the Giesler plastometer procedure, (2) overall average reflectance calculated from the average reflectance for each coal multiplied by compounding rate, and (3) the maximum fluidity for the two-description compounded coal.

Title: Text voice synthesizer
Inventor: KUNNSHIYAN RIN
IPC: G10L13/07
Filed: 1982-03-04
Abstract: An electronic, speech producing system receives allophonic codes and produces speech-like sounds corresponding to these codes, through a loud speaker. A micro-controller controls the retrieval, from a read-only memory, of digital signals representative of individual allophone parameters. The addresses at which such allophone parameters are located are directly related to the allophonic code. A dedicated microcontroller concatenates the digital signals representative of the allophone parameters, including code indicating stress and intonation patterns for the allophones. The allophones are divided into a plurality of frames with one digital position indicating whether the frame is the last frame in the allophone, in which event an extra frame is introduced to provide smoothing between allophones when no stop is present and when the present allophone is voiced and the subsequent allophone is voiced, or when the present allophone is unvoiced and the subsequent allophone is unvoiced. An LPC speech synthesizer receives the digital signals and provides analog signals corresponding thereto to the loud speaker to produce speech-like sounds with stress and intonation.
