Abstract: Ozone, preferably produced in an ambient air stream passed through a non-thermal hyperplasma reactor, is added to the hot exhaust gas stream from a lean-burn (oxygen-rich) combustion source. The ozone converts much of the NO in the NOx containing exhaust stream to NO2. The resulting NO2/NOx ratio can be controlled by the input energy density to the plasma reactor. Ammonia and/or urea is added to the ozone treated exhaust in proportion to the NOx content, and the stream passed into contact with a reduction catalyst, such as a base metal-exchanged zeolite, to convert the NOx to nitrogen.

Abstract: A method of partially oxidizing an alcohol to an aldehyde or ketone comprises contacting a gas containing the alcohol with a solid catalyst containing molybdenum, preferably in a +6 oxidation state, and having a surface area of 10 m2/g or higher, preferably 100 m2/g or higher. The molybdenum is supported on a high surface area carrier. The alcohol is a primary or secondary alcohol and preferably contains from 1 to 6 carbon atoms. In a preferred embodiment, the alcohol is ethanol. NOx emissions from an internal combustion engine can be lowered by combining the product of partial oxidation with the exhaust stream before passing the exhaust mixture through a lean NOx catalyst.

Abstract: A thermistor of which resistance is changed depending on temperature and a secondary battery to which the thermistor is attached are disclosed. The thermistor is attached to an object via a lead which is made of different kinds of materials. The lead is configured so that a part of the lead to be united to the thermistor electrode is mainly made of the same material as the electrode and a part of the lead to be united to the object is mainly made of the same material as the surface of the object. Thus, the thermistor may be simply attached to the object only using the ultrasonic welding, thereby remarkably reducing junction inferiorities.

Abstract: A sidestream located hyper-plasma reactor having an axially discrete pattern of alternating regions of active and passive electric field along the axial direction. The hyper-plasma reactor has great efficacy in terms of ultra low power consumption and copious production of NOx converting aldehydes in the absence of NO by applying plasma power only to an air and hydrocarbon mix sidestream gas flow. Only a small fraction (1% to 2%) of plasma power is required as compared to that for a conventional plasma reactor to treat the full exhaust gas stream. The hyper-plasma reactor produces ozone which reacts subsequently with hydrocarbons to produce aldehydes (“ozonolysis”). The sidestream location of the hyper-plasma reactor allows for the full exhaust stream to bypass it, without significantly affecting the overall NOx conversion performance in the catalytic converter.

Abstract: Disclosed is a lithium secondary battery with high stability and excellent performance, and its manufacturing method. The lithium secondary battery includes a positive electrode including a positive electrode active material, a conductive material and a binding material and a negative electrode including a negative electrode active material and a binding material, and PTC powder is contained in at least one of the positive electrode and the negative electrode. If the battery is overheated due to overcharge, the PTC powder contained in the positive electrode and/or the negative electrode abruptly increases electric resistance to break electric current, thereby preventing further increase of temperature and resultantly preventing fire or explosion. In addition, the conductive material is contained separately from the PTC powder, performance of the battery is not deteriorated in the normal operation.

Abstract: A thermistor, which is to be mounted on a PCB, for protecting other circuit elements is disclosed. Electrode patterns separately formed on both surfaces of a film resistance element are respectively shaped into two parts which are engaged to each other with a non-conductive gap interposed therebetween. Thus, a Tombstone phenomenon caused by asymmetric structure may be fundamentally prevented. Grooves are formed in both sides of the thermistor, and connection portions for electrically connecting the electrodes formed on both surfaces of the thermistor are formed through the inside of the grooves or through the sides except the grooves. Thus, though a crack arises in the connection portion, it is possible to prevent the crack from being propagated to the entire connection portion along the side of the thermistor.

Abstract: An image format conversion apparatus including a 3:2 pull-down detection part determining whether a current field out of plural fields continuous in time is an image of a 3:2 pull-down format produced by a 3:2 pull-down process; a scroll text/graphic data detection part determining whether scroll motions exist on the current field; a 3:2 pull-down compensation part calculating interpolation values for pixels of the current field to be interpolated by using a 3:2 pull-down interpolation method; an IPC part calculating interpolation values for pixels of the current field to be interpolated by using a second interpolation method; and an output selection part for selectively outputting either the interpolation values of the 3:2 pull-down compensation part or the interpolation values of the IPC part based on results of the determinations of the scroll text/graphic detection part and the 3:2 pull-down detection part.

Abstract: A thermistor is disclosed, which comprises a resistance element having upper and lower surfaces and showing a resistance varying characteristics according to the change of temperature; first and second conductive layers formed on the upper surface of the resistance element and engaged to each other with a non-conductive gap interposed therebetween; first and second electrodes formed on the lower surface of the resistance element and electrically separated from each other; a first connector for electrically connecting the first conductive layer to the first electrode; and a second connector for electrically connecting the second conductive layer to the second electrode. Thus, the thermistor has a structurally point-symmetric shape, so it is possible to prevent the Tombstone phenomenon, caused by an asymmetric structure.
