Abstract: A printing apparatus for printing on printing media in a continuous business form. The apparatus includes a transport device, a detector for detecting a splice portion between the printing media transported by the transport device, a printing section for printing on the printing media transported by the transport device, a drying section for drying at a drying temperature the printing media printed in the printing section and transported by the transport device, and a controller for operating the transport device to reduce tension applied to the splice portion at least while the splice portion is located in the drying section.

Abstract: A method for reproducing lithium sulfide, including the steps of reacting lithium halide generated as a byproduct during the production of a polyarylene sulfide by a reaction between lithium sulfide and a halogenated aromatic compound with sodium carbonate to generate lithium sulfide, isolating the lithium carbonate and reacting the lithium carbonate with a sulfur compound to generate the lithium sulfide. According to the above method, lithium sulfide having a less Na content can be reproduced from lithium halide generated as a byproduct during the production of a polyarylene sulfide.
