Abstract: The invention relates to a vacuum-sealed container comprising: a container body (10); a container cover (20) having hinge portions (22); a handle (30) comprising a pair of rotating cylinders (31) having first ends rotatably coupled to respective hinge portions (22) of the container cover (20) and having channels (34, 35) to communicate with the container body (10), a pair of elevating bars (36) coupled to second ends of respective rotating cylinders (31) to be able to move upward/downward, and a connecting bar (37) for connecting the elevating bars (36), a ventilation channel (38) formed in at least one rotating cylinder (31) or in the elevating bar (36); a first check valve (40) that opens/closes first ends of the channels (34, 35) of the handle (30) as the elevating bars (36) of the handle (30) move upward/downward; and a second check valve (50) that opens/closes the ventilation channel (38).

Abstract: The invention is a cooking container with steam eliminating function comprising: an outer container 10 and having an lid 13 and a steam vent 14; an inner container 20 being inserted in the outer container 10; a heating material 30 disposed in the outer container 10 and generating heat by reacting with water; a steam blocking means 40 including a cooling body 41 having a cooling chamber 42a to be filled with cooling means 44, and a steam exhaust pipe 45 provided in the cooling chamber 42a of the cooling body 41 and a part of it being exposed outside of the cooling body 41 and the exposed end of it being removably engaged into the steam vent 14 of the outer container 10.

Abstract: A multilayer ceramic capacitor includes: a ceramic body including dielectric layers and first and second internal electrodes disposed to face each other with respective dielectric layers interposed therebetween; and first and second external electrodes disposed on an external surface of the ceramic body, wherein the dielectric layer contains a barium titanate-based powder particle having a core-shell structure including a core and a shell around the core, the shell having a structure in which titanium is partially substituted with an element having the same oxidation number as that of the titanium in the barium titanate-based powder particle and having an ionic radius different from that of the titanium in the barium titanate-based powder particle, and the shell covers at least 30% of a surface of the core.
