To provide a method for producing an aqueous liquid containing a vinyl polymer, of which the production efficiency is high, without lowering the yield of the vinyl polymer. When removing a hydrophilic organic solvent from a mixed liquid comprising a vinyl polymer, the hydrophilic organic solvent and water to produce an aqueous liquid containing the vinyl polymer, a liquid phase and a gas phase are formed in a closed container, a part of the liquid of the liquid phase is formed into small droplets and brought into contact with the gas phase to vaporize the hydrophilic organic solvent, and the vaporized hydrophilic organic solvent is removed from the closed container. Specifically, for example, a closed containerhaving a liquid inlet, a gas outlet, a liquid outlet, a liquid inletand a liquid outletwhich are connected and having an external circulating system provided with means to control the temperature and the pressure of liquid, is filled with a mixed liquidto form a liquid phaseand a gas phase, the mixed liquidof the liquid phaseis circulated from the liquid outletto the external circulating system, and the temperature and the pressure of the mixed liquidin the external circulating systemare controlled to conditions such that the hydrophilic organic solvent is easily vaporized in liquid droplets in the gas phase, followed by discharging the mixed liquidin the form of the small droplets from the liquid inletto the gas phaseand draining the gas in the gas phasefrom the gas outlet

Method for producing vinyl polymer-containing aqueous liquid and method for producing water/oil resistant agent

A hand-written graphic form inputting apparatus by which a plurality of hand-written graphic forms can be inputted efficiently is disclosed. When a hand-written graphic form inputted from a graphic form inputting device is recognized so as to produce graphic form candidates and the graphic form candidates thus produced are stored into a graphic form candidate buffer, a graphic form relation determination device determines the correlation between the inputted graphic form inputted and the graphic form candidates. The graphic form determination device determines a most likely graphic form candidate from among the graphic form candidates in accordance with a result of a determination from the graphic form relation determination device. A graphic form position determination device determines the size of the graphic form to be displayed on a display device in accordance with a result of the determination from the graphic form relation determination device and a graphic form position determination device determines the orientation of the graphic form to be displayed on a display device in accordance with a result of the determination from the graphic form relation determination device.
