Abstract: The present invention relates to a novel method for preparing an itopride-hydrochloride mediate of the formula 1, which is useful for digestive tract activator, and more particularly, the present invention provides with a method for preparing 4-[2-(dimethylamino)ethoxy]benzylamine of the formula 1, an itopride-hydrochloride mediate, whereby being capable of manufacturing in a high yield and lowering cost through a simple purification and a selective reaction, and the method is harmless and safe to human and environment due to not generating toxic gas. And specially, a super-high pressure hydrogenation and a reduction reaction using a metal catalyst are not carried out, therefore, it is very safe method, and also special manufacturing equipments are not needed.

Abstract: A method for the construction of a highly integrated semiconductor connecting device. In the semiconductor connecting device, a plurality of third conductive lines are connected with a plurality of first conductive lines formed in the active regions of a semiconductor substrate through contact holes formed on the active regions, passing by and being insulated with a plurality of second conductive lines which are intercalated between a first interlayer insulating film and a second interlayer film and which are formed above a plurality of device separation insulating films formed in the semiconductor substrate. With the method, a stepped part is avoided thereby eliminating a cause of a the short circuit caused by remnant conductive material. In addition, the charge storage electrodes are connected with the source electrodes, while being securely disconnected from the bit lines.

Abstract: The polymer buildup problem that may occur in the reactor where the inversion polymerization of vinylchloride is conducted can be effectively ameliorated by way of coating the internal surfaces of the reactor with a mixture comprising an expanding lattice clay, e.g., veegum, and a water-soluble suspending agent, e.g., polyacrylic acid.
