Abstract: An electrode coating device includes a die block including a first die and a second die coupled to each other, and at least one of the first die and the second die having an accommodating portion for accommodating slurry, a shim plate partially disposed along a circumference of the accommodating portion between the first die and the second die to form a discharge port through which the slurry is discharged, and an expansion plate coupled to the shim plate, wherein the shim plate includes: a first section, second sections, and a third section, wherein the expansion plate is disposed in a form expanding a width of the third section in a region corresponding to the accommodating portion.

Abstract: The present invention provides a multi-layer selector device exhibiting a low leakage current by controlling a threshold voltage. According to an embodiment of the present invention, the multi-layer selector device comprises: a substrate; a lower electrode layer disposed on the substrate; an insulating layer disposed on the lower electrode layer and having a via hole passing through to expose the lower electrode layer; a switching layer disposed on the lower electrode layer in the via hole, performing a switching operation by forming and destroying a conductive filament, and made of a multi-layer to control the formation of the conductive filament; and an upper electrode layer disposed on the switching layer.

Abstract: A container lid includes: a rotating body detachably joined to a mouth of a container in a spiral manner; a cover of which the end is connected to one side of the rotating body to open and close the mouth of the container; an insertion part formed in the cover to be inserted and fixed into the mouth of the container so that the cover can close the mouth of the container; a hinge part of which the end is connected to one side of the rotating body to support the opening and closing actions of the cover; and a pressing part formed on the cover to be pressed to the mouth of the container by rotation of the rotating body so that the degree of opening of the cover is controlled.
