Abstract: Disclosed herein is a method for forming a dual gate of a semiconductor device. The method comprises the steps of forming a first polysilicon layer doped with p-type impurity ions and a second polysilicon layer doped with n-type impurity ions on a first region and a second region of a semiconductor substrate, respectively, and sequentially subjecting the surfaces of the first and second polysilicon layers to wet cleaning, drying, and dry cleaning. The wet cleaning is performed by using a sulfuric acid peroxide mixture (SPM), a buffered oxide etchant (BOE), and Standard Clean-1 (SC-1) as cleaning solutions.

Abstract: A method for fabricating a sintered annular nuclear fuel pellet includes: molding nuclear fuel powder or granules to fabricate an annular nuclear fuel green body; inserting a rod-like shaped structure into the annular nuclear fuel green body; sintering the rod-like shaped structure-inserted annular nuclear fuel green body in a reductive gas atmosphere; and separating the sintered annular nuclear fuel pellet from the rod-like shaped structure.

Abstract: A method for fabricating a sintered annular nuclear fuel pellet includes molding nuclear fuel powder or granule, an oxide of a fissile element (M), to fabricate an annular nuclear fuel green body. A rod-like shaped structure is inserted into the annular nuclear fuel green body and sintered in a slight oxidizing gas atmosphere such that the oxide of the fissile element has a balanced O/M ratio higher than a desired O/M ratio (oxygen/fissile element) of a final sintered annular nuclear fuel pellet, while being maintained in a cubic phase. The sintered annular nuclear fuel pellet is then reduced in a reductive gas atmosphere so as to have the desired O/M ratio in the state that the rod-like shaped structure is inserted.

Abstract: A method for manufacturing an annular nuclear fuel pellet is provided. In the method, an annular nuclear fuel green compact whose lateral cross-section is a trapezoid is prepared. The thickness of the annular nuclear fuel green compact reduces along one direction of the central axis, and a green density of the nuclear fuel green compact increases along one direction of the central axis. The annular nuclear fuel green compact is sintered under a reducing gas atmosphere so that the annular nuclear fuel pellet is obtained. According to this method, the annular pellet which has uniform inner and outer diameters and small diametric tolerances along the pellet height is fabricated without grinding the pellet surfaces.

Abstract: Provided is an apparatus for inputting a character which enables users to input characters more conveniently by arranging input keys having 3 or 4 input interfaces appropriately in a keypad. If the present invention is applied to small sized electronic equipment such as a mobile phone and PDA, much more various types of characters can be arranged as compared with the space the input keys take, and thereby it becomes possible to input characters faster with the minimum amount of effort.

Abstract: A submersible offshore marine aquaculture apparatus comprises a lower frame configured to suspend plumb bobs therefrom and to form a lower shape of the apparatus; and an upper frame configured to form an upper shape of the apparatus, and to support nets together with the lower frame. The upper frame includes a rim structure having an inner space to accommodate seawater or air therein, a fixed buoyant body disposed at the inner space of the rim structure so as to maintain a constant buoyancy (B0), and one or more valves configured to open and close the inner space of the rim structure so as to vary a buoyancy (B1) of the rim structure.

Abstract: An oxide pattern forming method comprises forming an oxide layer on a semiconductor substrate, implanting boron ions of not less than 1.0×1016 atoms/cm2 onto the oxide layer in a given region, and wet-etching the oxide layer in the remaining region where the boron ions are not implanted.

Abstract: Respective memory locations are assigned for respective edges linking processing nodes of a decoder comprising a plurality of processing nodes. The decoder is applied to a coded input signal to generate a decoded output signal, wherein edge values are iteratively retrieved from and provided to the memory locations such that multiple ones of the memory locations are simultaneously accessed in a processing node operation. The processing nodes may comprise variable nodes and check nodes and the edges comprise edges linking the variable and check nodes. The invention may be embodied as methods, apparatus and computer program products.

Abstract: The invention relates to a mobile phone holder for attaching a mobile phone to a body part of a user or to a dashboard or other structures in a vehicle. The mobile phone can be intermittently rotated under the manipulation of the user and attached/detached to a waist belt or the structures in the vehicle in an easy and secure manner. This prevents loss of the mobile phone while ensuring convenience in use.

Abstract: A belt holder for portable phones is disclosed. In the holder, the cover plate has a horizontal guide opening at its middle portion, with a guide channel being formed at the top center of the cover plate. A clip plate is assembled with the cover plate into a housing of the holder. A locker is vertically and movably set in the holder at a position between the cover and clip plates so as to be vertically movable in the gap between the two plates. The locker has two inclined guide portions at both side edges with the two inclined guide portions being converged downwardly. Two locking pieces are symmetrically and movably seated in the horizontal guide opening of the cover plate. The two locking pieces cooperate with both the locking button of a portable phone at their first slope surfaces and the inclined guide portions of the locker at their second slope surfaces.

Abstract: A holder for cellular phones is disclosed. In the case of a case-separated holder, the holder of this invention has an elastic member and elastically holds a phone case, thus allowing a cased cellular phone to be easily and simply handled by one hand when the phone is held on or removed from the holder. The above case-separated holder also limits the rotating angle of the cased cellular phone relative to the holder, thus preventing a sudden separation of the cellular phone from the phone case. In the case of a case-integrated holder, the holder has a means for limiting the rotating angle of a phone case relative to the holder, thus allowing the phone case to be rotated freely or within a limited angle relative to the holder. The case-integrated holder thus prevents the cased cellular phone from pressing a part of a user's body when a user sits on a chair, and prevents the holder from being deformed by a tensile force.
