Abstract: A liquid electromagnetic valve includes an inlet connected to an external liquid source; an outlet discharging liquid entering from the inlet; a flow path forming member having a flow path connecting the inlet and the outlet formed thereto; an opening-closing member capable of opening and closing the flow path; a drive portion opening and closing the opening-closing member based on a control performed by an external element; and a minute bubble generator provided in the flow path and having plural narrowing portions for adding minute bubbles to a liquid passing through the flow path by narrowing the flow path in plural stages.

Abstract: The present invention provides a water-soluble film having excellent solubility in cold water, high strength, and excellent hard-water resistance. The present invention also provides a method for simply producing such a water-soluble film. One aspect of the present invention relates to a water-soluble film including a polymer containing an anionic group other than a sulfonic acid (salt) group, and a water-soluble resin. The anionic group-containing polymer excludes an acrylic acid homopolymer. Another aspect of the present invention relates to a method for producing a water-soluble film that includes a polymer containing an anionic group other than a sulfonic acid (salt) group, and a water-soluble resin. The method includes mixing a polymer containing an anionic group other than a sulfonic acid (salt) group and a water-soluble resin.

Abstract: Disclosed is a method of establishing working mantime in a production line comprising the steps of: numerically evaluating the work volume for the working means performed in each production process, representing the numeralized work volume as a normal work mantime, then numerically evaluating the fatigue extent of each fatigue task as a fatigue score, and adding the fatigue score to the normal work mantime.Further, the fatigue score is assigned as a fatigue recovery mantime, and the normal work mantime which includes the fatigue recovery mantime is leveled as uniform, thereby establishing a new production process which includes the leveled fatigue recovery mantime.
