Disclosed herein is a method of manufacturing a multilayered ceramic capacitor by a spin coating process, and a multilayered ceramic capacitor obtained by the above method. The method of the current invention provides a plurality of dielectric layers formed by spin coating, in which the process of coating the dielectric layer and the process of printing the inner electrode can be provided as a single process. Therefore, the thickness of the dielectric layer is easily controlled while the dielectric layer is formed to be thin. Further, since the dielectric layers and the inner electrodes are formed successively, the processes of separating and layering the dielectric layers, and the process of compressing the ceramic multilayered body can be omitted. Thereby, the ceramic multilayered body need not be compressed, and thus, a pillowing phenomenon does not occur in the multilayered ceramic capacitor.

A method for manufacturing a multilayer ceramic capacitor, in which internal electrodes printed on each of a plurality of dielectric sheets have reduced thicknesses using an absorption member, thereby allowing the multilayer ceramic capacitor to have a high capacity and be minimized. The method includes printing the internal electrodes on each of the dielectric sheets, and stacking the dielectric sheets, wherein the internal electrodes formed on each of the dielectric sheets have a reduced thickness by causing an absorptive member to contact the surface of each of the dielectric sheets provided with the internal electrodes and then separating the absorptive member from the surface so that portions of the internal electrodes having a designated thickness are eliminated, and the dielectric sheets provided with the internal electrodes having the reduced thickness are stacked to form a chip element.

Disclosed is a necklace type radio headset capable of overcoming problems of conventional headsets, in which cables connected between earphones of a headset easily get tangled with each other or with other objects in a storing place of the headset while the headset is not used. The headset according to the present invention includes casings connected via a cable and enclosing one or more Bluetooth modules and respective speakers therein, and the casings are detachably coupled to each other by a coupling means, so that a user can wear the headset around his or her neck like a necklace because the cable always maintains a ring shape. As the coupling means, one of the casings has a depression for receiving a speaker housing to be inserted into a user's ear, and the speaker housing is input in the depression while it is not used. Further, since either or both of the casings have respective permanent magnets, the casings are coupled by attractive magnetic force exerted between the permanent magnets. According to the present invention, cables of a headset do not easily get tangled with each other or do not easily get tangled with other objects. Further, since a user can carry the headset by putting the headset around his or her neck, the headset cannot easily be lost.

Provided is a manufacturing method of a multi-layer ceramic substrate. The manufacturing method includes preparing an unsintered ceramic laminated body with a cavity, mounting a chip device within the cavity, filling the cavity, in which the chip device is mounted, with a ceramic slurry, attaching a constrained layer on top and/or bottom of the ceramic laminated body, and firing the ceramic laminated body. Accordingly, since the deformation of the cavity is prevented during the firing of the ceramic laminated body, the dimension precision and reliability of the multi-layer ceramic substrate can be improved.
