Abstract: A method of producing carboxylic acid and alcohol, that includes: supplying a liquid to a first distillation tower, said liquid including a carboxylic acid ester, and said first distillation tower being operated in a total reflux condition, to obtain a side stream; supplying said side stream to a hydrolysis reactor that includes an acid catalyst to obtain a reaction product liquid that includes a carboxylic acid, an alcohol, water and a carboxylic acid ester; supplying said reaction product liquid to said first distillation tower and removing a first bottom liquid therefrom, said first bottom liquid including a carboxylic acid, an alcohol and water; supplying said first bottom liquid to a second distillation tower and separating said first bottom liquid into a first top distillate that includes an alcohol, and a second bottom liquid that includes a carboxylic acid and water; supplying said second bottom liquid to a third distillation tower and separating said second bottom liquid into a second top distillate

Abstract: Electronic parts are mounted onto a substrate. A parts supply device holds a plurality of electronic parts and moves to be positioned at a predetermined parts take-out position. The parts supply device includes a readable and writable memory for storing data indicative of the plurality of electronic parts held therein. A reading device reads the data stored in the readable and writable memory provided in the parts supply device when the parts supply device moves relative to the reading device to the predetermined parts take-out position. The electronic part is extracted from the parts supply device position at the predetermined parts take-out position and mounted on a substrate.
