Abstract:
An apparatus and method for obtaining data regarding toner refilled in an image forming apparatus, to achieve the highest printing quality using the refilled toner. The method includes checking whether the image forming apparatus has been refilled with toner; checking whether toner identification information is present, when the image forming apparatus has been refilled with toner; obtaining toner data using the toner identification information from outside the image forming apparatus, when the toner identification information is present; and determining the toner data in the image forming apparatus, when no toner identification information is present. Accordingly, when the image forming apparatus is refilled with better toner than the original, it is possible to improve the quality of printing by setting data regarding the refilled toner in the image forming apparatus.

Abstract:
A polyester multi-filamentary yarn having a novel internal microstructure, polyester tire cord produced from the yarn and a process for production thereof are provided. The polyester yarn has a novel three-phase microstructure consisting of crystalline, amorphous and mesomorphous portions which are changed to a structure having crystalline and amorphous portions during formation of a tire cord. The polyester resin contains at least 90 mol. % polyethylene terephthalate. The resin is melt-spun and solidified by quenching to produce an undrawn yarn having a birefringence of 0.03 to 0.08, which is then drawn at a total draw ratio of 1.4:1 to 2.2:1 and thermally treated and relaxed. The resulting filamentary yarn is dipped in a rubber solution to produce a tire cord which exhibits excellent dimensional stability and fatigue resistance when it is incorporated into the rubber matrix of a tire.
Abstract:
Methods of manufacturing a semiconductor device include forming a conductive layer on a substrate, forming an air gap or other cavity between the conductive layer and the substrate, and patterning the conductive layer to expose the air gap. The methods may further include forming conductive pillars between the substrate and the conductive layer. The air gap may be positioned between the conductive pillars.
Abstract:
The present invention provides a separator for a fuel cell that improves efficiency of the fuel cell by removing water generated in a membrane-electrode assembly and accumulated in a channel of the separator, a manufacturing method thereof, and a fuel cell stack including the same. The separator for the fuel cell of the present invention includes: a main body of a plate shape; a channel concavely formed in at least one surface of the main body and supplying a fuel or oxygen to a membrane-electrode assembly; and a metal layer provided to a surface of the channel and including an oxide layer formed by an anodic oxidation treatment and minute grooves of a nano-scale formed in the oxide layer, thereby forming the surface of the channel to be super-hydrophilic.

Abstract:
An exhaust gas post processing system may include an exhaust pipe in which an exhaust gas from an engine passes, a catalyst that may be disposed at the exhaust pipe so as to decrease a harmful material of the exhaust gas, and a water jacket that may be formed around an exhaust pipe that may be disposed at an upstream side of the catalyst of the exhaust pipe, wherein a coolant may be selectively supplied into the water jacket such that the water jacket cools down the exhaust gas passing the exhaust pipe and thus the catalyst does not be over heated.
Abstract:
An exhaust system may include an exhaust line through which a combusted exhaust gas is exhausted outside, a nitrogen oxide purification catalyst that is mounted on the exhaust line and uses unburned fuel or hydrocarbon to reduce one part of the nitrogen oxide in the exhaust gas and diffuse the other part thereof to store therein, an injector that injects fuel into the exhaust line, a fuel cracking catalyst that is disposed between the injector and the nitrogen oxide purification catalyst to activate the additionally injected fuel from the injector through thermal decomposition so as to generate a reducing agent of high reactivity, and a control portion that controls the injector to additionally inject fuel in a predetermined condition such that the nitrogen oxide purification catalyst uses the activated reducing agent to detach and reduce the nitrogen oxide that is stored therein.
