Abstract: A switch apparatus, includes: a base module including a base case, and a moving magnet movably mounted in the base case; and a manipulation module including a manipulation case, and a first magnet fixedly mounted in the manipulation case, wherein the moving magnet moves between a hold position and a releasable position, the hold position refers to a position in which the manipulation module is held onto the base module as an attractive force acts between the moving magnet and the first magnet, and the releasable position refers to a position in which the manipulation module is releasable from the base module as a repulsive force acts between the moving magnet and the first magnet.

Abstract: A multilayer ceramic electronic component includes: a body including dielectric layers as well as a plurality of internal electrodes stacked with respective dielectric layers interposed therebetween and including a first metal; and external electrodes disposed on external surfaces of the body including a second metal, wherein at least some of the plurality of internal electrodes include a core-shell region including the first and second metals, and average contents of the second metal in a core portion and a shell portion of the core-shell region are different from each other.

Abstract: Disclosed herein is a tape feeder for chip mounters. The tape feeder is constructed so that front and rear locators are restrained by a restraint slot of a cam slider moving horizontally, and bearings of the front and rear locators alternatively execute vertical and horizontal movements while sliding along the restraint slot by a reciprocating motion of a cam slider, thus repeatedly moving a carrier tape backward while locking the carrier tape and moving the carrier tape forward while releasing the carrier tape, therefore allowing the carrier tape to be fed precisely. The tape feeder allows the carrier tape to be fed precisely, and prevents chips from being turned over and removed from the carrier tape when a vinyl cover is discharged, thus minimizing a malfunction of the chip mounter during an operation of the chips and thereby maximizing operational reliability. Further, the tape feeder allows the number of elements to be reduced, in addition to achieving a slim construction.
