摘要:
Provided is a method for manufacturing a grain-oriented electrical steel sheet, the method comprising: heating a grain-oriented electrical steel sheet slab; hot-rolling the heated slab; optionally annealing the hot-rolled steel sheet; subjecting the resulting steel sheet to one cold rolling or two or more cold rollings with intermediate annealing therebetween; subjecting the cold-rolled steel sheet to primary recrystallization annealing; and subjecting the annealed steel sheet to secondary recrystallization annealing, wherein the primary recrystallization annealing sequentially comprises an ultra-rapid heating process of heating the steel sheet at an average heating rate of 300° C./sec or higher, a rapid heating process of heating the steel sheet at a lower average heating rate than the average heating rate of the ultra-rapid heating process, but not lower than 100° C./sec, and a general heating process of heating the steel sheet at a lower average heating rate than the average heating rate of the rapid heating process.

A memory device includes a memory cell on a first region of a substrate. An active region is in a second region neighboring the first region of the substrate, and an extension direction of the active region has an acute angle with the direction of the substrate. A transistor serving as a peripheral circuit is on the second region of the substrate. In the memory device, defects or failures due to a crystal defects or a dislocation of the substrate may decrease.

A process and apparatus for separating an olefin from mixed gases containing light olefins is provided. The process includes adsorbing the olefin of an olefin-containing mixed gas in an adsorption column packed with an adsorbent selectively adsorbing the olefin; discharging gases other than the olefin through the outlet of the adsorption column; desorbing the adsorbed olefin by displacement using a desorbent, and separating the olefin from the desorbent, thereby producing a high-purity olefin. The apparatus includes adsorption columns packed with an adsorbent selectively adsorbing an olefin, and at least two distillation columns for separating an olefin/desorbent mixture and an olefin poor stream/desorbent into their components. If the olefin concentration of the off-gas from an olefin rinse step is higher than that of a raw material gas, recovering the olefin from the off-gas is carried out before or after the adsorption step.

An image forming apparatus includes: an image carrier unit that includes an image carrier and is configured to be capable of being housed in and removed from an image-forming-apparatus main body; an exposure device that is arranged close to the image carrier to form an electrostatic latent image; a retracting mechanism that holds the exposure device close to the image carrier when the image carrier unit is housed in the image-forming-apparatus main body, and holds the exposure device away from the image carrier when the image carrier unit is being removed from the image-forming-apparatus main body; a covering member that covers the retracting mechanism in a state where backlash of the exposure device at least in a main-scanning direction is allowed; and a guide mechanism that positions the exposure device in the main-scanning direction when the exposure device comes closer to the image carrier through the retracting mechanism.

A method for providing a personalized service in an Internet Protocol Television (IPTV) includes pairing a mobile terminal with the IPTV. The method also includes receiving personalized data from the paired mobile terminal, and searching the Internet for contents satisfying the received personalized data and providing the searched contents.
摘要:
A portable terminal includes an apparatus for controlling an operation of a mobile terminal. More particularly, an apparatus and a method sets a menu to control a mobile terminal in a specific region of an image stored in advance. A relevant function is performed by selecting the specific region of the image in which the menu has been set in the mobile terminal, thereby performing the relevant function fast and conveniently without separately selecting a menu (entering a menu). The apparatus includes a controller. The controller selects a specific region from an output image, sets a menu for controlling a function of the mobile terminal at the specific region, and stores the image where the menu has been set.

A user interface device of a remote control system for a robot and a method using the same are provided. The user interface device includes: a radio frequency (RF) unit for receiving, from a remote control robot, camera data and at least one sensor data detecting a distance; a display unit having a main screen and at least one auxiliary screen; and a controller having an environment evaluation module for determining whether the received camera data are in a normal condition, and having a screen display mode change module for displaying, if the received camera data are in a normal condition, the camera data on the main screen and displaying, if the received camera data are in an abnormal condition, the sensor data on the main screen.

A method, an apparatus, and a computer-readable medium to reduce power consumption of a wireless network device, the method including: receiving a packet; and determining whether to transmit the received packet to a host based on a state of the host and a packet transmission standard set for the host. Accordingly, it is possible to extend a period of use of a wireless portable terminal using an Internet protocol (IP)-based wireless network.
摘要:
Provided is an apparatus of determining the number of synthetic beams, comprising: a motion measurement unit which measures the degree of motion in an output beam-forming image; a synthetic beam number determination unit which determines the optimum number of synthetic beams based on the measured degree of motion in case of applying the synthetic aperture beam forming; and a display unit which displays the number of synthetic beams determined by the synthetic beam number determination unit. A system using synthetic aperture beam forming detects motion in an image and displays a degree of the motion in various manners, and thus, a user is allowed to actively cope with the motion by adjusting the number of synthetic beams, or the system is allowed to immediately change the number of synthetic beams with reference to data stored in advance.
