|20150037675||NEGATIVE ELECTRODE MATERIAL FOR LITHIUM SECONDARY BATTERY AND METHOD FOR MANUFACTURING THE SAME - To provide a high-capacity lithium secondary battery at a low price that attains an increased reversibility of charge and discharge, by using a new negative electrode material different from the existing negative electrode materials, and to provide a lithium secondary battery that can use an existing electrolyte at a small risk of ignition or overheating.||02-05-2015|
|20140170490||LITHIUM SECONDARY BATTERY NEGATIVE ELECTRODE AND METHOD FOR MANUFACTURING THE SAME - Provided is a negative electrode having a new structure for realizing a lithium secondary battery having increased charging/discharging capacities and a battery capacity that is reduced less due to repeated charging/discharging. The negative electrode for a lithium secondary battery includes a current collector substrate; a carbon nanochips layer including graphene sheets grown to incline in irregular directions independently from the current collector substrate; and a silicon thin film layer on the carbon nanochips layer, in which gaps among the carbon nanochips are formed between the silicon thin film layer and the current collector substrate. The Raman spectrum of graphite forming the carbon nanochips layer has a g/d ratio of 0.30 to 0.80, both inclusive, and the crystallinity level of the graphite is lower than that of graphite forming carbon nanowalls. The carbon nanochips layer can be formed by a plasma CVD method using a gaseous mixture of methane and hydrogen, for example.||06-19-2014|
|20120180465||EXHAUST APPARATUS OF INTERNAL COMBUSTION ENGINE - An exhaust gas apparatus of an internal combustion engine is capable of suppressing the sound pressure level from being increased by the air column resonance in the tail pipe. The exhaust gas apparatus being provided with an exhaust gas pipe at the downstream side of an internal combustion engine in the exhaust gas direction of an exhaust gas flow, the exhaust gas pipe having an upstream opening end at one end portion thereof and connected with a sound deadening device at the upstream side in the exhaust gas direction of the exhaust gas flow, and a downstream opening end at the other end portion thereof for exhausting the exhaust gas flow to the atmosphere.||07-19-2012|
|20090205386||Method for forming an end portion of a cylindrical workpiece - A method for forming a part of deformed cross section with non-rotation symmetry on an end portion of a cylindrical workpiece. The method includes steps of performing a first relative motion of a roller against the workpiece toward its one open end, and performing a second relative motion of the roller against at least a part of outer peripheral surface of the end portion of the workpiece toward the inside thereof, while the roller is rotated relative to the workpiece by one rotation, in such a state as being held to be in contact with the end portion, in a plane which is perpendicular to the moving direction of the first relative motion, and which includes a position where the roller contacts the outer peripheral surface of the end portion, and performing a rotational motion of the roller relatively rotating around the workpiece, while performing the second relative motion, with the roller being held to be in contact with the outer peripheral surface of the end portion. The first relative motion is performed up to a position exceeding the one open end, while repeating the second relative motion and the rotational motion.||08-20-2009|
