    Abstract: The present invention relates to an induction heating apparatus. In order to cope with various types of containers without increasing an operating frequency of an induction heating apparatus, the present invention compares a resistance value of a container with a predetermined reference resistance value, and determines an operating mode of a switching device according to a result of the comparison. According to the present invention, it is possible to use various types of containers without increasing an operating frequency of an induction heating apparatus, by adjusting a resonance frequency of a working coil according to a resistance value of a container used in the induction heating apparatus.

    Abstract: Disclosed is a shield for eyelash extension of an eyelash extension system for extending a subject's eyelashes by bonding fake eyelashes thereto. The shield includes a safety cover divided into an upper body and a lower body such that front ends of the upper body and the lower body are paired to be opened or closed together to bite a subject's eyelashes placed therebetween. The safety cover includes a concave curved receiving groove in a front end of the safety cover to accommodate the subject's eyelashes while in contact with a protruding eye of the subject with his or her eye closed, and a work space with an entrance open to a rear side is provided behind the receiving groove. The work space is for accommodating the eyelashes pulled by being bitten between the front ends of the upper and lower bodies and conducting eyelash extension work therein.

    Abstract: The present invention relates to an electrochemical device and a manufacturing method therefor. More specifically, the present invention relates to an electrochemical device in which, in an electrode assembly composed of a cathode, a separator, and an anode, at least one or more of the cathode, the separator, and the anode are formed of a gel polymer electrolyte and have different ion conductivities, and a manufacturing method therefor. Since the electrochemical device of the present invention includes electrolytes having different ion conductivities in at least one of the cathode, the separator, and the anode, it is possible to provide the optimized flow of ions for the separator and each electrode. Accordingly, the present invention has advantageous effects in improving the lifespan and safety of the electrochemical device.
