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 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.

The present invention relates to a hybrid process comprising an adsorption process and a distillation process for the separation of butene-1 from a C4 hydrocarbon mixture gas including butene-1, trans-2-butene, cis-2-butene, normal butane, isobutane, etc. The above hybrid process comprises introducing a gaseous C4 mixture into the adsorption tower loaded with adsorbents which adsorb olefins selectively to discharge C4 paraffins to the outlet of the tower, desorbing C4 olefins selectively adsorbed in the adsorption tower to produce high purity C4 olefins mixture gas in which isobutane and normal butane was removed, and separating the high C4 olefins mixture gas (a mixture of butene-1, trans-2-butene, cis-2-butene, and a trace amount of C4 paraffins) via distillation to obtain high purity butene-1 including a trace amount of isobutane in the top of the distillation tower and obtain a mixture gas including trans-2-butene, cis-2-butene and a trace amount of normal butane in the bottom of the tower.

The present invention relates to a method in which a catalytic reaction is used in order to produce hydrocarbons from renewable starting material derived from biological organisms such as vegetable lipids, animal lipids, and lipids extracted from macroalgae and microalgae, and more specifically relates to a method for selectively making a hydrocarbon, which is suitable for making gasoline or diesel, by removing the oxygen contained in the starting material without consuming hydrogen. In the present invention, the production takes place by bringing the starting material into contact with hydrotalcite, which constitutes a catalyst, thereby removing oxygen via a decarboxylation or decarbonylation reaction; and the starting material is one or more such material selected from triglycerides, fatty acids, and fatty acid derivatives obtained from a renewable source of supply originating from a biological organism.

A power saving apparatus and a method in a wireless communication system are provided. An Access Point (AP) buffers transmission frames for sleep-mode stations in a sleep-mode buffer. Upon wakeup from a sleep mode, a station sends a first control information frame indicating wakeup to the access point. The access point sends a second control information frame including a requested transmission length in response to the first control information frame to the station. The station generates a third control information frame, aggregates the third control information frame and user data frames to a first protocol data unit, and sends it to the AP. Then the AP generates a fourth control information frame, aggregates the fourth control information frame and buffered frames to a second protocol data unit, and sends it to the station.
