  • Publication number: 20190258679
    Abstract: In one aspect, a data accumulation apparatus includes a script execution environment, an accumulation and retrieval unit accumulating data and performing retrieval on the accumulated data, a notification unit outputting notification in response to that data newly accumulated in the accumulation and retrieval unit matches one of conditions registered in advance, and a storage unit storing scripts and action correspondence information. The script execution environment has property of being capable of describing an instruction to perform data retrieval and an instruction to perform communication through the network, according to a script being executed.

  • Publication number: 20180340043
    Abstract: Provided are a method of producing a polyarylene sulfide (PAS) by a polymerization reaction of a sulfur source and a dihalo aromatic compound in an organic amide solvent, in which the PAS having a high degree of polymerization can be obtained at a high yield and the generation of a byproduct that imposes a large burden of a waste treatment can be effectively reduced; and a PAS having a high degree of polymerization. The method of producing a PAS includes a preparation step of preparing a charged mixture containing an organic amide solvent, a sulfur source, water, and a dihalo aromatic compound; a first-stage polymerization step of performing a polymerization reaction on the charged mixture at a temperature of from 170 to 280° C. to produce a prepolymer having a conversion ratio of the dihalo aromatic compound of 50% or greater; and a second-stage polymerization step of continuing the polymerization reaction in a phase-separated state at a temperature of from 245 to 290° C.

  • Patent number: 9422400
    Abstract: A granular polyarylene sulfide; (i) the granular polyarylene sulfide containing an —S— substituent at the terminal, the substituent being formed by cleavage of a disulfide compound; (ii) the granular polyarylene sulfide being an oversize fraction after sifting with a sieve having a mesh size of at least 38 ?m; (iii) the granular polyarylene sulfide having a halogen content of at most 1,500 ppm; and (iv) the granular polyarylene sulfide being a granular polyarylene sulfide having a melt viscosity of 3 to 100 Pa·s when measured under conditions at a temperature of 310° C. and a shear rate of 1,200 sec?1. The granular polyarylene sulfide is well balanced in melt viscosity, halogen content, nitrogen content, thermal stability, and yield.
