Abstract: A button-type secondary battery includes a lower can having a bottom surface; an upper can having a top, the upper can and the lower can being coupled to define a space therein; an electrolyte in the space; an electrode assembly in the space and including a negative electrode, a separator, and a positive electrode wound together; a gasket between the upper can and the lower can to electrically insulate the upper and lower cans; a top insulator that is electrically insulating and covering a top surface of the electrode assembly; and a bottom insulator that is electrically insulating and covering a bottom surface of the electrode assembly. The top and bottom insulators are each configured to expand in volume by absorbing the electrolyte. Surfaces of at least one of the top insulator and the bottom insulator are coated with a protective layer to prevent thermal shrinkage from occurring.

Abstract: A button type secondary battery includes a wound electrode assembly; a lower can with the electrode assembly and an electrolyte in the lower can; a top plate to close the lower can; a positive electrode terminal coupled to the top plate through a gasket to be electrically insulated from the top plate with a portion of the positive electrode terminal passing through a hole in the top plate to be bonded to a positive electrode tab; a top insulator covering a top surface of the electrode assembly; and a bottom insulator covering a bottom surface of the electrode assembly. The top insulator and the bottom insulator are each configured to expand in volume by absorbing the electrolyte. Surfaces of at least one or more of the top insulator and the bottom insulator are coated with a protective layer configured to prevent thermal shrinkage from occurring.

Abstract: An inductor includes a first magnetic body having a toroidal shape and having a ferrite; and a second magnetic body configured to be different from the first magnetic body and including a metal ribbon, wherein the second magnetic body includes an outer magnetic body disposed on an outer circumferential surface of the first magnetic body and an inner magnetic body disposed on an inner circumferential surface of the first magnetic body, and each of the outer magnetic body and inner magnetic body is wound in a plurality of layers in a circumferential direction of the first magnetic body.

Abstract: The present invention provides a pharmaceutical composition for prevention or treatment of a stress disease and depression, the pharmaceutical composition be safely useable without toxicity and side effects by using an extract of leaves of Vaccinium bracteatum Thunb., which is natural resource of Korea, so that the reduction of manufacturing and production costs and the import substitution and export effects can be expected through the replacement of a raw material for preparation with a plant inhabiting in nature.

Abstract: The present invention relates to a cosmetic case with a sterilizer and a puff, and more particularly, a cosmetic case including a puff and a sterilizer for sterilizing the puff. The cosmetic case with the sterilizer and the puff according to the present invention is capable of sterilizing the puff combined to the case body with the ultraviolet ray from the sterilizer to prevent bacterial contamination and proliferation of the puff, thereby improving sanitation and storage quality, and is capable of frequent sterilization before and after use of cosmetics, thereby improving user's convenience for sterilization of the puff.

Abstract: The invention relates to a manicure receptacle having a drying part, including: a receptacle body which has an entrance formed in its upper portion and stores a manicure therein; and a cap which is coupled to the entrance of the receptacle body and has a support rod which is integrated with a brush in its lower portion and extends in the vertical direction, wherein the cap includes a drying part configured to dry a manicure applied on a nail or a toenail of a user by raising the wind. The manicure receptacle is capable of quickly drying a manicure applied on a nail or a toenail of a user by raising the wind, thereby shortening manicure drying time and improving convenience of manicure use.
