Title: Production of polyarylene sulfide
Inventor: SUGIE TOSHINORI
IPC: C08G75/02
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To enable to simply obtain the subject polymer excellent in thermal stability and having a high mol.wt. in a high yield in a state little in the distillation of reaction components by using a specific reaction vessel and selectively separating only water liberated in the reaction. SOLUTION: This method for producing a polyarylene sulfide comprises polycondensing (B) an alkali metal sulfide with (C) a polyhalogeno aromatic compound in (A) an organic amide polar solvent by the use of a reaction vessel 1 equipped with a rectifier 3 having intercoolers in the structure, while distilling out water in the system. For example, the bulkhead temperature of the rectifier 3 is maintained at a temperature higher than the steam distillation temperature [T( deg.C)] of the component C and water and lower than (T+10 deg.C), and the water or the component C is circulated as a reflecting liquid for the rectifier 3.  Thus, it can be prevented that the components A and C are distilled outside the system, and the component C distilled out from the rectifier 3 can directly be returned to the reaction vessel 1 through a condenser 4, etc., thereby enabling to substantially constantly maintain the B/C molar ration in the polycondensation reaction system.

Title: Stage for placing wafer
Inventor: YONEOKA YUJI
IPC: H01L21/68
Filed: 1991-12-04
Abstract: PURPOSE:To accurately measure a temperature during heating by gas heating medium by forming it of a gas sealing plate, a fine circular gold wire and a sealing surface of ceramics. CONSTITUTION:A temperature of a wafer 2 in vacuum is measured from a rear surface of an infrared ray thermometer 1 through a gas shielding plate 7 introduced into a pore 5 formed at a center of a heat block 3. In this case, the plate 7 is sealed with a fine circular gold wire 8. The other surface of the wire 8 is formed of a mirror-polished surface 9 of alumina.
