Abstract:
An incontinent liquid drip-preventative method for preventing occurrence of incontinent liquid drip of a fluid from a discharge port when a flow of said fluid supplied from a fluid supply source is shut off, said incontinent liquid drip-preventative method comprising the steps of:determining an operation control pattern comprising a velocity and acceleration of said fluid flowing through a fluid passage;controlling a flow amount of said fluid flowing through said fluid passage so that said fluid flows according to said operation control pattern until a flow line of said fluid discharged from said discharge port attains a predetermined constricted state;maintaining said predetermined constricted state for a preset time period; andclosing said fluid passage so that said flow amount of said fluid becomes zero after said flow line of said fluid discharged from said discharge port has been in said predetermined constricted state for said preset time period.
