    摘要: A method for producing a biaxially stretched film is provided, in which the method comprises, stretching a film made mainly of an ethylene-vinyl alcohol copolymer having an ethylene content of 15 to 70 mol % and a saponification degree of 80 mol % or more under heating; cooling the film; and subjecting the cooled film to a heat treatment; wherein a heating temperature during the stretching is 60 to 160° C., a cooling temperature is a temperature 30 to 100° C. lower than the heating temperature during the stretching, and a temperature for the heat treatment is 150 to 190° C. The thus obtained biaxially stretched film of the present invention has a small bowing coefficient.

    摘要: A material supplying apparatus includes a container for storing a solution; an inlet pipe for introducing a carrier gas and an outlet pipe; electrodes disposed in the container over the depth direction of the container and forming a capacitor; and apparatus for calculating a residual amount of the solution in the container from the capacitance of the capacitor formed by the electrodes. The solution is used as the dielectric of the capacitor formed in the container and the capacitance varies according to the quantity of solution so that the residual amount of the solution and the time to replenish the solution are calculated in a simple structure having no moving parts.
