A radiator fin of a heat sink has a shape of a portion of a circle with a small radius which is not overlapped with a circle with a large radius when two circles with different radiuses are overlapped with each other such that centers of the two circles are in a single circle, as a cross sectional shape. An arrangement of radiator fins of a heat sink on a radiator plate, includes at least two radiator fins provides to at least one radiator plate such that centers of inner and outer arcs of circles forming the radiator fins are on a reference line, and an outer arc of one of two adjacent radiator fins moves within a track of an inner arc of the other radiator fin or an inner arc of one radiator fin moves out of a track of an outer arc of the other radiator fin.

A dish washing machine having a basket height adjusting apparatus. The dish washing machine includes a machine body having a washing tub defined therein, a basket disposed in the washing tub to receive dishes to be washed, and a basket height adjusting apparatus. The basket height adjusting apparatus includes a support bracket mounted at each side of the basket such that the support bracket can be moved vertically, rollers mounted to the support bracket to slide the basket forward and backward, and an adjusting lever mounted at the basket to adjust a vertical movement of the support bracket and to thereby adjust the height of the basket. The adjusting lever is moved along with the basket. Consequently, in the present invention, the thumb of a user is not caught in the basket and injured when the user rotates the adjusting lever.

A structure of a data frame for transmitting data via a relay, and a transmission apparatus and a relay using the data frame are provided. The relay includes: a receiver to receive, from a transmission apparatus, first radio resource allocation information with respect to a first radio resource and second radio resource allocation information with respect to a second radio resource, and to receive first data from the transmission apparatus using the first radio resource allocation information; and a transmitter to transmit the received first data to a receiving apparatus using the second radio resource allocation information.
摘要:
Prior to deposition of a silicon nitride (SiN) layer on a structure, a non-plasma enhanced operation is undertaken wherein the structure is exposed to silane (SiH4) flow, reducing the overall exposure of the structure to hydrogen radicals. This results in the silicon nitride being strongly bonded to the structure and in improved performance.

An exhaust valve apparatus and a drier of a food treatment system having the exhaust valve apparatus are disclosed. The drier includes a drum having an input port and a discharge port. A stirring screw is rotatably disposed in the drum, and includes rotary blades for stirring and crushing the food waste and a rotating shaft for supporting the rotary blades. A power supply unit is provided on a surface of the drum and provides power to the stirring screw to rotate the stirring screw. A heater is provided on the outer surface of the drum body and provides high temperature heat to the inner space of the drum when electric power is applied to the heater, thus drying the food waste. An exhaust apparatus is mounted to the lower surface of the discharge port to open or close the discharge port.

A washing machine having a plurality of washing units to separately wash laundry according to quantity and type of the laundry, and a method to control the same. In the washing machine having the plurality of washing units to separately wash laundry having different quantities and types, when the plurality of washing units are being simultaneously operated, a current load value of one of the washing units is detected through monitoring of a power line, to thereby determine the operation state of the washing unit. Therefore, the operation of the other washing unit may be controlled so that the power limit is not exceeded. As a result, the plurality of washing units may be operated simultaneously within the range of allowable power capacity of the installation place of the washing machine.

A washing machine and a control method thereof are disclosed. The washing machine has a plurality of washing tubs to clean laundry in different ways classified according to capacity and types of clothing. Different washing tubs simultaneously stop operations or are stopped at different times spaced apart from each other by a predetermined time, although washing tubs have different washing conditions (e.g., different input times of laundry, different amounts of laundry, different washing courses, etc.) when laundry is cleaned using the washing tubs.

Provided are a semiconductor device and a manufacturing method thereof. A pair of adjacent gate structure can be formed on a substrate. Mask patterns exposing a portion located between the gate structures are formed. The substrate portion located between the gate structures can be etched using the mask patterns as an etch mask to form a pocket. First conduction type impurities can be implanted into the pocket to form a first impurity layer in a surface of the pocket. Second conduction type impurities can be implanted into the pocket to form a second impurity layer on the first impurity layer. The pocket can be filled with an insulating material. Accordingly, impurities having a type opposite to the type of source junction impurities are implanted into the pocket to reduce a potential barrier of a source junction. Consequently, punch-through generated between a source and a drain can be inhibited.
