The hollow fiber membrane module contains a hollow fiber membrane bundle having bundled hollow fiber membranes, a housing with an internal space formed in which the hollow fiber membrane bundle is housed and a gas supply portion which disperses cleaning gas for the hollow fiber membrane in the internal space. The internal space has an upper space in which an upper-side part of the hollow fiber membrane is positioned and a lower space in which a lower-side part of the hollow fiber membrane is positioned. The gas supply portion is provided with pipe vent holes which disperse gas in the housing at a position in the upper space and diffusing vent holes which disperse gas in the housing at a position below the lower space.

The present invention provides a method for producing a zinc sulfide based phosphor by firing a zinc sulfide based precursor, comprising at least: a first firing step and a second firing step. Use of the method of the present invention makes it possible to provide a zinc sulfide based phosphor material suitable in the production of an EL device that shows high brightness.

Method for producing zinc sulfide based phosphor

The present invention provides a polarized electrodecontaining mixed activated carbon composed of at least two activated carbons with different specific surface areas, and the specific surface area of the mixed activated carbon is not less than 900 m/g and less than 1900 m/g. By setting the specific surface area of the mixed activated carbon to less than 1900 m/g, the resistance reduction ratio of the polarized electroderapidly increases.
