Abstract: A heat converter according to one embodiment of the present invention comprises: a plurality of unit modules respectively arranged in a first direction and a second direction that intersects the first direction; and a frame, which supports the plurality of unit modules, allows cooling water to flow in through one surface arranged in the first direction, and allows the cooling water to be discharged through the other surface arranged in the first direction, wherein each unit module includes: a cooling water passage chamber having first and second surfaces arranged to be spaced in the first direction, third and fourth surfaces arranged to be spaced in a third direction that intersects the first direction and the second direction, a fifth surface arranged to be spaced in the second direction such that cooing water flows therein, and a sixth surface from which cooling water is discharged; a first thermoelectric module arranged on the first surface; and a second thermoelectric module arranged on the second surface

Abstract: A ceramic electronic component includes a body including a dielectric layer and an internal electrode; and an external electrode disposed on the body and connected to the internal electrode. The dielectric layer includes a plurality of grains and grain boundaries disposed between adjacent grains. The grain boundary includes a secondary phase including Sn, a rare-earth element, and a first subcomponent. The rare-earth element includes at least one of Y, Dy, Ho, Er, Gd, Ce, Nd, Sm, Tb, Tm, La, Gd and Yb. The first subcomponent includes at least one of Si, Mg, and Al.

Abstract: The present invention provides an operating module comprising: a vehicular multi-operating switch unit; a module housing configured to allow the vehicular multi-operating switch unit to be movably accommodated therein; a module drive unit disposed in the module housing and configured to generate a driving force that moves the module housing; a module unit shuttle configured to allow the vehicular multi-operating switch unit to be accommodated therein, the module unit shuttle being movably disposed in the module housing; and a module drive transfer unit connected at one side thereof to the module drive unit and connected at the other side thereof to the module unit shuttle, and configured to transfer a driving force that moves the vehicular multi-operating switch unit relative to the module housing, wherein a switch knob is provided at an end of the switch shaft unit, is moved together with the module unit shuttle in response to the movement of the module unit shuttle, and forms a grip for a user, and wherein
