Title: Tautology check method and instrument for the same
Inventor: GUNNAA MARUCHIN NATANAERU SUTA
IPC: G06F11/22
Filed: 1990-06-15
Abstract: PURPOSE: To accelerate the processing speed with a simple constitution by converting a formula to be checked to plural triplets and making the formula tautologeous in the case that one triplet is a terminal. CONSTITUTION: A formula is divided into partial formulas what is called a triplet in which part each includes three terms, and variables in triplets are designated to true values (logical 0:S or 1:S) for the purpose of checking true contents. An effective arithmetic rule can be formulated by this division to triplets for the purpose of calculating true values of partial formulae in the original formula. Consequently, true values of the original formula are calculated without requiring analysis of all combinations of true values of variables of the original formula. Thus, all variables of the original formula are not checked but those of triplets are checked, and a required number of test sequences is reduced to shorten the time.

Title: Recovery of terephthalic acid
Inventor: ARASHI MASAKIMI
IPC: D06M101/16
Filed: 1983-08-31
Abstract: PURPOSE:To recover high-purity terephthalic acid in the form of stably and sufficiently grown crystals, in high yield, by carrying out the continuous acid precipitation of an aqueous solution of a terephthalic acid alkali metal salt within a specific pH range using sulfuric acid diluted to a specific concentration. CONSTITUTION:An aqueous solution of an alkali metal salt of terephthalic acid (e.g. waste water from the thinning process of polyester fiber) is subjected to the continuous acid precipitation process at 2.0-4.0pH using sulfuric acid diluted to a concentration of <=33wt%, to recover terephthalic acid. A continuous reactor is used in the above treatment. The hydrogen ion concentration is well balanced with the terephthalic acid ion concentration in the above reactor, and the crystal can be grown sufficiently when the solution is retained in the reactor for >=20 min. The increase in the size of the crystal affords the precipitation separation of the crystal, improves the efficiency of dehydration and drying processes, prevents the mixing of salt inherent to fine crystals, and gives the recovered terephthalic acid having sufficiently high purity to be used as a raw material without purification.
