摘要:
Provided is a large-capacity metal catalyst support and a catalytic converter using the same, in which a number of unit catalyst support blocks are changed in a form of being effectively assembled so as to be applied to a catalytic converter that is required for processing a large amount of exhaust gas such as large vessels or plants employing a number of large-scale internal combustion engines, or large food processing devices, to thus easily assemble the unit catalyst support blocks into a large-scale assembled structure. The catalyst support includes: a number of unit catalyst support blocks in which cell formation bodies formed of a number of hollow cells that are aligned in a longitudinal direction are accommodated and stacked in a polygonal supporter wherein a catalyst is coated on the surfaces of the hollow cells; and a number of assembly members each for fixing a pair of adjacent supports that mutually contact between the stacked unit catalyst support blocks.

Provided is a catalyst converter for purifying exhaust gas and a method for manufacturing the catalyst converter, in which a heater is disposed between inner/outer monoliths, to thereby heighten a heat transfer efficiency and induce a uniform catalytic reaction, and to thereby enhance a processing performance, and minimize an electric power consumption and miniaturize a device. The catalyst converter includes: a heater having a winding portion which is wound so as to have a space therein and a pair of electric power terminals; inner and outer monoliths which are inserted in the inner and outer circumferential portions of the heater winding portion wherein each of the inner and outer monoliths includes a number of hollow cells on the surfaces of which catalysts have been coated and which are formed in the lengthy direction; and a housing in which a support assembly is assembled.

Provided is a drying heater, a heating unit for drying laundry using the same, a drying control system and control method thereof that reduces electric power consumption of the drying heater to supply high temperature dry air to the inside of a drum in a washing machine or a laundry drying machine, to thus simplify structure of the drying heater and reduce a manufacturing cost. The drying control method includes the step of applying a first electric power from a first drive power supply to a drying heater when a drum internal temperature is lower than a preset temperature, and applying a second electric power from a second drive power supply which is relatively smaller than the first electric power to the drying heater when the drum internal temperature is higher than the preset temperature. The drying heater includes a surface-shaped heat generation member made of a low thermal density strip style metal thin plate.

Provided is a pipe having an anti-freezing function including a strip type surface heating element which is capable of having a function of preventing the pipe from freezing and bursting, and a fabricating method thereof, in which the pipe is a relatively thin film and includes a surface heating element therein. The anti-freezing pipe includes: a ribbon heater which has a strip type surface heating element which emits heat when electric power is applied to both ends of at least one strip, and the strips are arranged with an interval in parallel with each other when the strip type surface heating element is formed with a number of strips, and an insulation layer which is coated on the outer circumference of the strip type surface heating element in a plate form, and which is spirally wound to form a cylindrical shape; and a spiral junction portion which pins side surfaces of the spirally wound ribbon heater.

A mobile communication terminal having QWERTY keys and a method for outputting Dual Tone Multi-Frequency (DTMF) signals thereof are disclosed. The user inputs information including alphabetic characters that is requested by a directory system, while viewing the alphabetic characters marked on the QWERTY keys. The mobile communication terminal outputs DTMF signals of symbols marked on the input QWERTY keys identical to the DTMF signals of the corresponding symbols of keys arrayed in a conventional 3×4 key array format. The alphabetic keys of the QWERTY keys output DTMF signals identical to those of the keys of the 3×4 array format in an alphabet input mode. Therefore, the user can easily input information requested by the directory system while viewing the symbols marked on the QWERTY keys, without requiring the user to memorize the array of alphabetic characters of the 3×4 key array format.
