Abstract: Disclosed herein is a shock absorber for damping vibration transmitted to a vehicle according to a road state. The shock absorber includes a cylinder and a piston valve disposed within the cylinder and connected to a piston rod to divide the cylinder into a first chamber and a second chamber. The shock absorber further includes a hollow chamber formed within the piston rod, a floating piston disposed within the hollow chamber to move up and down and to divide the hollow chamber into upper and lower chambers, first and second orifices formed in upper and lower ends of the hollow chamber and connected to the first and second chambers, respectively, and a resistance changing mechanism configured to cooperate with the floating piston and change a fluid resistance with respect to the floating piston where the resistance changing mechanism cooperates therewith.

Abstract: The present invention relates to a process for the preparation of optically pure amlodipine gentisate, more particularly to a continuous process for the preparation of optically pure amlodipine gentisate with good yield and high optical purity. The processes can be preformed by first reacting racemic (R,S)-amlodipine and optically pure O,O?-dibenzoyltartaric acid in the presence of a solvent including isopropanol to prepare (R)- or (S)-amlodipine dibenzoyltartarate diastereomer or a solvate thereof, treating the prepared amlodipine diastereomeric salt or a solvate thereof with a base and then finally adding gentisic acid.

Abstract: The present invention relates to a method for optical resolution of amlodipines by using isopropanol solvent and optically active O,O?-dibenzoyl tartaric acid as chiral reagent. More particularly, the present invention relates to a method comprising (a) obtaining (R)— or (S)-amlodipine dibenzoyl tartrate salt or solvate thereof by reacting (R,S)-amlodipines with optically active O,O?-dibenzoyl tartaric acid in isopropanol solvent, and (b) treating the (R)— or (S)-amlodipine salt with a base, thus obtaining optically active amlodipine.

Abstract: An apparatus and method is provided for allowing an improved power key function of a mobile communication terminal that enhances user convenience by providing an independent backlight function for the power key when a mobile communication terminal is opened while in a power OFF state. By providing an independent backlight function for a power key of the mobile communication terminal, the present invention facilitates illuminating the power key when the mobile communication terminal is opened and in a power OFF state.

Abstract: An apparatus and method for detecting a moving object in a sequence of color frame images is provided. The apparatus comprises a color normalizer for normalizing color components of the color frame image to produce a normalized frame image; a color transformer coupled to the color normalizer for color transforming the normalized frame image to a color transformed frame image; the color transformed frame image having intensity levels such that colors corresponding to said moving object are emphasized; a frame delay coupled to the color transformer for delaying the color transformed frame image by one frame; and a motion detector coupled to the color transformer and the frame delay for detecting the motion of the moving object and further intensifying the intensity levels of the color transformed frame image based on the detected motion.

Abstract: A personal rapid transit (PRT) system having a linear induction motor installed on the bottom of a vehicle is provided. Since a linear induction motor is installed on the bottom of a vehicle, the structure of the personal rapid transit (PRT) system is simplified and the stable driving thereof is possible. Further, since an auxiliary ramification wheel is provided, an accident by the vehicle seceding from a track occurring during ramification can be prevented in advance. That is, since only a single linear induction motor is installed horizontally on the bottom of the vehicle and thus the vehicle is driven, the structure of the personal rapid transit (PRT) system is more simplified and becomes lighter, and a production cost can be reduced, in comparison with an existing system using a pair of linear induction motors. In addition, even if a ramification device is failed during ramification, a track secession can be suppressed with an auxiliary ramification wheel provided, to thereby guide a stable running.

Abstract: Disclosed is a semiconductor device capable of protecting an internal circuit from an ESD impact, damage and a mistaken working caused by an electrostatic discharge, a surge pulse and a noise, and more particularly to a semiconductor device capable of protecting an internal circuit from an external abnormal input without a protection circuit. The semiconductor device includes a varistor coupled to a conductor for discharging an abnormal input signal input to a ground voltage level. The varistor acts as a conductor when an input signal is an abnormal input signal and acts as an insulator when the input signal is a normal input signal. The use of the varistor may provide an improved ESD protection circuit and then promote the reliability of the semiconductor device.
