Title: Method for recovering vinyl chloride polymer using dichloromethane
Inventor: KITO TAKETOSHI
IPC: C08J11/08
Filed: 2002-03-08
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem that though recently the solvent method has been noticed as a method for recovering a vinyl chloride polymer from a polyvinyl chloride product composed of the vinyl chloride polymer, however, an operator is fearful that use of an organic solvent is dangerous, some method has difficulty in separation between a good solvent and a poor solvent and it is rather difficult to say that the solvent method is an established method.  <P>SOLUTION: Dichloromethane having no fear of inflammability and explosivity under a normal condition is used as a main. Consequently grave danger is avoided and dichloromethane is extremely readily separated from most poor solvents due to its low boiling point. Many polyvinyl chloride products can be treated even without being finely ground.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a combustion control device for a direct-injection diesel engine in which premixed compression ignition combustion is performed by performing advanced injection in a premixed combustion region (H) on a light load side and setting an EGR rate at a 1st set value or higher, whereas diesel combustion is performed in a diffusion combustion region (D) on a heavy load side to bring an EGR rate to at most a 2nd set value, and to prevent the transient deterioration of exhaust conditions and noise generation from occurring in transition between the operation regions (H) to (D).  <P>SOLUTION: When combustion shifts from either of the combustion regions (H) and (D) into the other in the engine 1, and the combustion shifts from premixed compression ignition combustion into diesel combustion, firstly the valve travel of an EGR valve 35 is reduced to make an actual EGR rate EGR to a switched EGR rate (specified value EGR2) between the 1st and 2nd set values, and then a fuel injection mode is switched. Whereas in the case of shifting from diesel combustion to premixed compression ignition combustion, the fuel ignition mode is switched after the actual EGR rate EGR has become a switched EGR rate (specified value EGR1) between the 1st and the 2nd set values.  <P>COPYRIGHT: (C)2004,JPO
