Abstract:
A memory system includes a flash memory device and an interface device. The flash memory device includes a one-time programmable block where protection data information is stored in a predetermined region, and the interface device includes a register for storing one-time programmable lock status information to indicate whether the one-time programmable block is programmed. When a program/erase command is applied externally in a one-time programmable mode, the interface device having the one-time programmable lock status information indicates whether the one-time programmable block is programmed. If the one-time programmable lock status information indicates that the one-time programmable block is programmed, the interface device cuts off an external access to the one-time programmable block.
Abstract:
A self-service machine using a communications terminal and a service providing method thereof. The self-service machine includes an antenna for receiving a radio signal including identification information of the self-service machine and price information, a radio transceiver for processing the radio signal from the antenna, an information processor for extracting the price information from the signal processed by the radio transceiver if the identification information from the radio transceiver is identical to its actual identification information, a controller for controlling the self-service machine so as to provide a predetermined service according to the price information from the information processor, a service providing unit for providing the predetermined service under the control of the controller, and a memory for storing predetermined information about the service provided by the self-service machine after the provision of service by the service providing unit. Therefore, the self-service machine such as a vending machine or a ticket vending machine, can be used by a cellular phone or a wire/wireless telephone, without the need for cash or a card.

Abstract:
Provided is a 3-way switch for a gas-insulated apparatus, including a pressure container having a space part therein, the pressure container including a first connecting part in an upper portion of the space part and a second connecting part in a side portion of the space part such that the second connecting part is perpendicular to the first connecting part, a support conductor provided in the space part, the support conductor having a first guide hole defined in a direction perpendicular to the direction of the first connecting part and a second guide hole defined in a direction parallel to the direction of the second connecting part, a disconnecting switch (DS) operating part slidably coupled to the first guide hole, the DS operating part being connected to or separated from the first connecting part by means of an insertion or extrusion thereof, an earthing switch (ES) operating part slidably coupled to the second guide hole such that the ES operating part is perpendicular to the disconnecting switch operating part, the ES operating part being connected to or separated from the second connecting part through an insertion or protrusion thereof, and a main lever, one end of which is rotatably coupled to the support conductor and the other end of which is eccentrically rotated and rotatably connected to the DS operating part and the ES operating part so as to linearly slide the DS operating part and the ES operating part into neutral positions.
Abstract:
Disclosed are novel rhodanine derivatives which are inhibitory of HIV activity. Also provided are a method for preparing the novel rhodanine derivatives, and a pharmaceutical composition for the prevention or treatment of AIDS containing the rhodanine derivatives as active ingredients. Having high inhibitory activity against HIV, the rhodanine derivatives can be effectively used in the prophylaxis or therapy of AIDS.
Abstract:
Disclosed are indole derivatives, a preparation method thereof, and a composition for the prevention and treatment of metabolic diseases, containing the same as an active ingredient. The indole derivatives have inhibitory activity against DGAT (diacylglycerol acyltransferase), which causes metabolic diseases such as obesity and diabetes in the process of lipid metabolism. With the ability to effectively control lipid metabolism and energy metabolism, the composition is thus useful in the prevention and treatment of metabolic diseases, such as obesity and diabetes.
Abstract:
An electron emission display and a driving method thereof, where a brightness is adjusted differently according to a brightness of a frame in order to reduce power consumption and prevent a brazing fire from occurring, and to easily recognize a change of the brightness. The display includes a pixel portion adapted to receive a data signal and a scan signal, the pixel portion being further adapted to display an image, a data driver adapted to generate the data signal using video data, the data driver being further adapted to transfer the data signal to the pixel portion, a scan driver adapted to transfer the scan signal to the pixel portion, a timing controller adapted to transfer a drive signal to the data driver and to the scan driver, the drive signal driving the data driver and the scan driver, a data processor adapted to generate a control signal corresponding to frame data obtained by summing a size of video data input during one frame and a power supply section adapted to generate a drive power source and transfer the drive power source to the pixel portion, the data driver, the scan driver, the timing controller, and the data processor, wherein a brightness of the pixel portion is varied according to the control signal, and an amount varied of the brightness is determined based upon the size of the video data during the one frame.
