A common mode filter is disclosed. The common mode filter in accordance with an embodiment of the present invention includes: a magnetic substrate; a coil pattern formed on the magnetic substrate; a dielectric layer formed on the magnetic substrate so as to cover an upper part, a lower part and a side surface of the coil pattern; and a first coupling agent interposed between the magnetic substrate and the dielectric layer so as to prevent the magnetic substrate and the dielectric layer from being separated.

Common mode filter

A common mode filter is disclosed. The common mode filter in accordance with an embodiment of the present invention includes: a magnetic substrate; a dielectric layer laminated on the magnetic substrate; an external electrode formed on the dielectric layer in such a way that one surface thereof is exposed to an outside; a conductive pattern formed on a surface of the dielectric layer so as to be located on a same plane as the external electrode and having one end thereof connected with the external electrode; an insulator film formed on a surface of the conductive pattern; and a magnetic layer formed on the insulator film so as to cover an upper surface and a lateral surface of the conductive pattern.

A common mode filter is disclosed. The common mode filter in accordance with an aspect of the present invention includes: a first dielectric layer having a first groove formed along an outer boundary portion thereof; a second dielectric layer coated on the first dielectric layer so as to cover a first coil laminated on the first dielectric layer, having a first protrusion corresponding to the first groove formed on one surface thereof being in contact with the first dielectric layer, and having a second groove formed on the other surface thereof; and a third dielectric layer coated on the second dielectric layer so as to cover a second coil laminated on the second dielectric layer, having a second protrusion corresponding to the second groove formed on one surface thereof being in contact with the second dielectric layer, and having a third groove formed on the other surface thereof.

An ink-jet head is disclosed. The ink-jet head can include: a chamber for holding ink, an actuator coupled to one side of the chamber to provide pressure to the chamber, a damper portion connected with the other side of the chamber, an accelerator portion extending from a lateral surface of the damper portion, and a nozzle formed at an end of the accelerator portion. Certain embodiments of the invention can be used to increase the speed at which ink is ejected and improve the straightness of the ejection path.

Ink-jet head

Disclosed are an ink-jet head and a method of manufacturing the ink-jet head including a plurality of chambers, a membrane covering the plurality of chambers, and a plurality of actuators separated from one another by a virtual dividing line on the membrane such that pressure is applied to each of the plurality of chambers. The method in accordance with an embodiment of the present invention includes: forming a groove at a position on one surface of the membrane, the position corresponding to the position of the dividing line; bonding a piezoelectric member to the one surface of the membrane having the groove formed therein by using adhesive resin; and dividing the piezoelectric member such that the groove is exposed.

Ink-jet head and manufacturing method thereof

An ink-jet head is disclosed. The ink-jet head can include: a channel for holding ink, a nozzle connected with the channel, a pressurizing unit configured to apply pressure to the ink so as to eject the ink, a partition coupled to one side of the channel so as to block the channel, and an actuator configured to deform one side of the channel so as to open the channel. While pressure is applied to the ink, this pressure can be turned on and off, to provide pressure pulses for ejecting the ink. As such, with this arrangement, the ejection properties of the ink-jet head can be adjusted to various settings.
