A regeneration reactor of a CO2 capture system is disclosed. According to an embodiment of the present invention, in the CO2 capture system comprising a capture reactor selectively adsorbing CO2 by bringing a CO2-containing gas supplied from the outside into contact with a solid adsorbent, and a regeneration reactor separating the adsorbed CO2 from the solid adsorbent adsorbed with the CO2, the regeneration reactor includes a chamber having an inverted truncated cone shape being widened toward an upper part and narrowed toward a lower part, such that a pressure in the regeneration reactor is constantly maintained through the whole part and accordingly, a flow velocity in the chamber can be constantly maintained.
Abstract:
A system and method for interworking a Converged-IP Messaging (CPM) service to another messaging service. In particular, the present invention realizes a function of allowing a CPM service's recipient to receive a message sent from another CPM service's sender using a non-CPM service to which the recipient has subscribed. To this end, the present invention uses preference information of a recipient in determining a non-CPM service to be subjected to interworking. In this way, the CPM service can interwork with non-CPM services, contributing to expansion of an area where services can be provided.
Abstract:
A vessel block arranging device extracts image information on a vessel block loaded on a transporter, and determines whether to arrange the vessel block in an area in which the vessel block will be arranged by using location information of the arranged vessel block in the area and extracted image information, thereby reducing errors caused by determining the vessel block arrangement.
Abstract:
The present invention relates in general, to a chip antenna and, more particularly, to a dual-band small-sized chip antenna, in which a first antenna element, including a plurality of coil members, is coupled with a second antenna element, having a plurality of circuit patterns, in a zigzag fashion, thus forming resonance frequencies, and relates to a multi-band chip antenna fed with current from external part wherein the third antenna element having coil formed in helical form and the fourth antenna formed parallel with the third antenna element and in helical form are connected to the fifth antenna having a plurality of circuit pattern on the layered-substrate, and relates to chip antenna using multi-layered radiator to generate the mutual coupling of two radiator by placing non-feeding radiation element having fixed pattern between the radiator for performing the radiation of the low frequency band and the radiator for performing the radiation of the high frequency band and to have wide band characteristic by forming multiple current path to radiator.

A structure of a bubble prevention buffer tank of a fuel cell vehicle is provided that comprises at least one mesh and at least one lattice inside the buffer tank so as to remove air bubbles inside the buffer tank by breaking the air bubbles.
Abstract:
Disclosed herein is an embedded chip antenna. The embedded chip antenna having a complementary radiator structure includes two radiators that have identical radiation characteristics and are respectively arranged on both sides of a feed point. According to the present invention, the radiator of a chip antenna has a single physical radiator structure, but is electrically formed of a plurality of partial radiators symmetrical with respect to a feed point, and radiation operations in high and low frequency bands are separately performed. Therefore, complementary operational characteristics that counteract external effects are implemented, so that, when part of a human body, such as the hand, affects one partial radiator on one side of the chip antenna, the other partial radiator on the other side thereof independently operates, thereby minimizing performance degradation originating from the outside of the antenna.
Abstract:
An etchant for removing an indium oxide layer includes sulfuric acid as a main oxidizer, an auxiliary oxidizer such as H3PO4, HNO3, CH3COOH, HClO4, H2O2, and a Compound A that is obtained by mixing potassium peroxymonosulfate (2KHSO5), potassium bisulfate (KHSO4), and potassium sulfate (K2SO4) together in the ratio of 5:3:2, an etching inhibitor comprising an ammonium-based material, and water. The etchant may remove desired portions of the indium oxide layer without damage to a photoresist pattern or layers underlying the indium oxide layer.
