  • Patent number: 10246604
    Abstract: 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.
    Type: Grant

  • Patent number: 5742280
    Abstract: 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.

  • Patent number: 5267492
    Abstract: In an automatic automotive transmission system having a torque converter and a gear transmission unit, the gear transmission unit is shifted from one speed stage to another normally according to current vehicle speed and engine load, but is upshifted from one speed stage to a subsequent speed stage according to a vehicle speed and a stored value of the engine load at the time of the preceding upshift so that a series of upshifts may be carried out at regular intervals, and the vehicle operator may accomplish a smooth acceleration of the vehicle substantially without any efforts even when the engine load wavers from the level at the time when the preceding upshift took place.
