Abstract:
A developing device that attaches/detaches to/from a main body of an image forming apparatus includes a photosensitive drum, a charging roller to rotate while contacting the photosensitive drum to charge a surface of the photosensitive drum to a uniform potential, and a separating member to rotate between a first position where the charging roller is separated from the photosensitive drum and a second position where the charging roller contacts the photosensitive drum. The separating member includes a body into which a rotary shaft of the charging roller is inserted to be rotatable, and a contact portion extending from the body and contacting the surface of the photosensitive drum when the separating member is located at the first position so as to separate the charging roller from the photosensitive drum, wherein the contact portion includes a friction member including rubber.
Abstract:
A wireless communication system is disclosed. Specifically, a method of transmitting signals from a user equipment in a wireless communication system that supports carrier aggregation comprises receiving downlink scheduling information from a base station through a control channel of a first downlink component carrier, the downlink scheduling information including an uplink transmission power control (TPC) command; receiving downlink data from the base station through a shared channel of a second downlink component carrier, the shared channel being connected with the downlink scheduling information; adjusting transmission power of an uplink component carrier corresponding to the first downlink component carrier in accordance with the uplink TPC command; and transmitting acknowledgement (ACK) information of the downlink data to the base station through the uplink component carrier.
Abstract:
A method for programming a non-volatile memory device includes: providing a non-volatile memory device including data cells capable of storing N-bit data (N is a natural number) and a monitoring cell capable of monitoring whether the N-bit data has been programmed into the data cells; performing a first programming operation for the data cells while inhibiting programming of the monitoring cell; and performing a second programming operation for the monitoring cell while inhibiting programming of the data cells, wherein the second programming operation is performed differently from the first programming.
Abstract:
Disclosed is a digital garment using embroidery technology. In the digital garment, a digital embroidery pattern is formed on a common garment to provide a communication path, an antenna pattern, etc. The digital garment comprises a garment made of a textile and having one side and the other side opposite to each other, a digital embroidery pattern formed along the inner or outer surface of the garment using embroidery technology to provide a communication path to the garment, a sensor attached to the garment and electrically connected to the digital embroidery pattern to convert physical signals to electrical signals, an arithmetic unit attached to the garment and electrically connected to the digital embroidery pattern to process the electrical signals inputted from the sensor, and a communication module attached to the garment and electrically connected to the digital embroidery pattern to perform wireless communication. Further disclosed is a method for fabricating the digital garment using embroidery technology.
Abstract:
A TemporoMandibular Joint (TMJ) balancing appliance and a method for using the same are provided, in which a first base portion accommodates incisor teeth, a second base portion is extended from a left side of the first base portion and accommodates left molar teeth, and a third base portion is extended from a right side of the first base portion and accommodates right molar teeth. The first base portion includes an upper part for accommodating upper incisor teeth and a lower part for accommodating lower incisor teeth and has a center for accommodating the upper and lower incisor teeth higher than the left and right sides.
Abstract:
Disclosed is a data transmission/reception method and system for minimizing intercarrier interference (ICI) in a communication system using a multicarrier. The data transmission method by a transmitter includes grouping transmission signals in units of a predetermined number of transmission signals when the transmitter has received the transmission signals, multiplying each group of the transmission signals by a transmission coding matrix, and transmitting the transmission signals multiplied by the transmission coding matrix to a receiver.
Abstract:
Disclosed herein is a method of fabricating a cliché capable of preventing a printing roller from touching a bottom surface of the cliché. The method of fabricating the cliché includes forming a mask thin film pattern having a multilayer structure and a photoresist pattern on a base substrate, forming a resistant reinforcement inducing layer to cover the photoresist pattern, thereby transforming the photoresist pattern into a resistant reinforced photoresist pattern, and forming groove patterns having different depths from each other by etching the base substrate using the resistant reinforced photoresist pattern and the mask thin film pattern having the multilayer structure as masks.
