Abstract:
A plate tube type heat exchanger using porous fins is manufactured of foamed metal. The porous fins used for the plate tube type heat exchanger are formed of a foamed metal such as aluminum or copper having a high thermal conductivity. The plate tube type heat exchanger using such porous fins exhibits an excellent heat transfer capability, compared to a conventional plate tube type heat exchanger using louvered fins, thereby simplifying production steps and realizing an excellent structural rigidity.
Abstract:
In a method of manufacturing an offset printing substrate and a method of manufacturing a display substrate, the method includes forming a first coating layer on a base substrate on which is formed a first concave pattern having a first width. An intermediate substrate is also formed upon the first coating layer of the base substrate, the intermediate substrate having a pattern corresponding to the first concave pattern. An offset printing substrate is also formed upon the pattern of the intermediate substrate, the offset printing substrate having a second concave pattern is formed to correspond to the pattern of the intermediate substrate, and the second concave pattern has a second width smaller than the first width.
Abstract:
A data forwarding method and system is provided for avoiding data loss during a vertical handover by forwarding data through an IP tunnel established between a newly introduced network entity called a Data Forwarding Function of the serving network and a Forward Attachment Function of a target network. A data forwarding method of a data forwarding unit located in a serving network for a vertical handover according to the present invention includes receiving an address of a forwarding attachment unit located in a target network and a data forwarding preparation request that are transmitted by a user equipment; establishing an Internet Protocol (IP) tunnel to the forwarding attachment unit according to the data forwarding preparation request; and forwarding, when a vertical handover is initiated, handover packets to the forwarding attachment unit through the IP tunnel.

Abstract:
A heat exchanger having an extended surface plate includes a plurality of heat exchanging bodies having therein flow paths along which a heat transfer medium flows, and extended surface plates each disposed between the heat exchanging bodies and having inclined surfaces in horizontal and vertical directions. Also disclosed is a dehumidifier having the heat exchanger. Moisture in the air may be effectively absorbed by a dehumidifying liquid, and the heat exchanger may have enhanced structural strength.
Abstract:
A log-in system for web page access in a vehicular platform using a NFC terminal is provided. The system includes a computer (PC) that stores and manages addresses of web pages that the user has accessed and personal information such as identification (ID) and a password required to log-in for each corresponding web page in a user database (DB). A server receives registration for log-in information from at least one computer via the Internet and manages the log-in information accordingly. A portable terminal having an NFC function downloads and stores information for the web pages, which have been accessed by the portable terminal, and log-in information from the computer or the server. A vehicle platform then receives the log-in information stored in the portable terminal via NFC and automatically executes log-in for an Internet web page based on the log-in information.

The portable refrigerator with a fuel cell system comprises a case having a storage space, a fuel cell stack disposed in the case, a gas tank configured to store gas necessary to operate the fuel cell stack, a fan configured to cool the fuel cell stack and supply air to the fuel stack, a thermoelectric cooling means disposed in the case, and configured to cool the storage space, a battery charged by the fuel cell stack, and configured to supply power to the thermoelectric cooling means, and a controller configured to control the fuel cell stack and the thermoelectric cooling means.
Abstract:
A regenerative evaporative cooler (REC) including: a plurality of dry channel units allowing indoor air to pass therethrough; a plurality of wet channel units formed to extract a portion of air, which has passed through the dry channel units, and formed to heat-exchange with the dry channel units; an evaporation water supply unit disposed at an upper portion of the wet channel units and supplying the wet channel units with evaporation water; and dry channel shields formed at an upper side of the dry channel units, allowing evaporation water supplied from the evaporation water supply unit to be introduced into the wet channel units, and shielding the upper portions of the dry channel units. The dry channel shield effectively prevents evaporation water sprinkled by the evaporation water supply unit from being introduced into the wet channels and simplifies the configuration of the evaporation water supply unit.
Abstract:
Disclosed are a complex-patterned wire net, which is mainly used for fences, and a method for manufacturing the same. The complex-patterned wire net (A) includes first net holes (100) in an even number obtained in zigzag by repeatedly forming twisting parts (110, 120, 130) by stretching longitudinal wires from twisting parts (110, 120, 130), obtained by twisting two strands of wires, to the right and left and twisting the longitudinal wires with the neighboring longitudinal wires at an interval of extensions (140, 150, 160), such that upper and lower portions of the longitudinal wires divided by divisional transversal wires (170, 180) supplied during twisting are twisted in the opposite directions, and second net holes (200) in an even number obtained by repeatedly forming twisting parts (210) by repeatedly forming twisting parts (210) by stretching longitudinal wires from the lowermost twisting parts (130) of the first net holes (100) to the right and left and twisting the longitudinal wires with the neighboring longitudinal wires at an interval of extensions (160), such that portions of the longitudinal wires divided by each of plural compartmental transversal wires (220) are twisted in the opposite directions.
