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:
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.
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:
A system and a method for stabilization control may control position and direction of an object having first and second bodies connected to each other. The system may include an artificial vestibular apparatus for outputting a movement signal corresponding to movement of the first body and a rotation signal corresponding to rotation of the first body; a translating actuation unit connected between the first and second bodies and controlling position of the second body in response to the movement signal; and a rotating actuation unit connected between the first and second bodies and controlling rotation of the second body in response to the rotation signal. If the system and the method are applied to a vision system of a mobile robot, the vision system may obtain stabile image information even when the mobile robot is moving. Thus, it is possible to prevent any blurring from occurring at the image information.
Abstract:
A pressure adjusting valve for a vehicle fuel line includes a diaphragm disposed in a housing and dividing the interior of the housing into first and second compartments. A valve plate is provided in the second compartment and attached to the diaphragm. A return unit is provided in the second compartment. An elastic member provides an elastic force to the diaphragm toward the second compartment. An elastic force adjusting unit controls the elastic force of the elastic member.

A method and apparatus for receiving information regarding content related to particular content interested by a user and downloading the related contents in a terminal are disclosed. The method for receiving content related to a particular content, includes: transmitting a content request message including a content identifier of a particular content to a server; receiving a content response message including information regarding content related to the content identifier from the server, wherein if there are at least one or more contents related to a global content identifier, the global state code has a value indicating success; checking whether there exists second information in guide information referred to by the first information on the related contents; receiving the second information if there is not the second information; and initiating a service request procedure by using the referred reception information.
Abstract:
A method of detecting or diagnosing a neurodegenerative disease in a subject by an immunoassay is provided. The immunoassay comprises obtaining a sample from a subject and assaying the sample for the presence of autoantibodies against certain epitopes of heterogeneous nuclear ribonuclear protein A1 (hnRNP A1). The presence of antibodies against a polypeptide or a fragment of polypeptide having the sequence of SEQ ID NO: 1, 4, 5, 6, 7, 8, 9 or 10, an epitope within the M9 shuttling sequence and/or an epitope within the RGG domain of hnRNP A1 indicate a neurodegenerative disease in the subject. Methods of treating neurodegenerative diseases are also provided. In one embodiment, the method of treating a neurodegenerative disease comprises administering, to a subject, a composition comprising hnRNP A1, fragments of the polypeptide and/or a polypeptide comprising epitopes within the M9 and/or RGG domains of hnRNP A1.
