Abstract: The present invention provides a pulverizer of a food waste treatment apparatus. The pulverizer of the present invention includes a main body, a pulverizing screw and an exhaust channel unit. The main body has a hollow space therein. The pulverizing screw includes a rotating shaft which is installed in the main body so as to be rotatable, and at least one drive blade which extends from the rotating shaft. The exhaust channel unit has an annular shape and is coupled to the upper end of the main body. An intake hole and an exhaust hole are formed through the outer surface of the exhaust channel unit. Furthermore, a cover may be removably coupled to the upper end of the exhaust channel unit.

Abstract: A field emission display device (FED) is provided. The FED includes a first substrate, a phosphor layer being in contact with the first substrate, and an anode electrode on the phosphor layer. The FED further includes a second substrate facing the first substrate and including a cathode electrode and an emitter disposed toward the anode electrode.
