Abstract: An ice removing mechanism includes an ice tray having a fixing projection at one end thereof and a sliding projection at the other end thereof, a rotating guide plate having a fixing groove at one side thereof to guide the fixing projection of the ice tray inserted thereinto and a connecting shaft rotatably connected to an output shaft of a motor at the other side thereof, a fixing guide plate having a guide groove concentrically disposed to a center thereof, a twisting member disposed between the guide plates, and a movable stopper for preventing the ice tray from rocking from side to side. When the rotating guide plate is rotated, the sliding projection of the ice tray is rotated to slide along the sliding groove of the fixing guide plate, thereby pressing a bottom surface of the rotated ice tray. As a result, the ice cubes are effectively removed from the ice tray.

Abstract: A cool air circulation apparatus in a refrigerator provides an upper curved lip extended from a front face of a lower shelf in a refrigerating chamber, by which cool air contacting with ambient air is discharged outside of the refrigerator and only the cool air adjacent to the refrigerating chamber flows into the refrigerating chamber. Accordingly, even though a door of the refrigerating chamber is open for a long time or is opened and closed frequently, ambient air does not enter into the refrigerating chamber and thus cooling efficiency of the refrigerator increases. As a result, a constant temperature in the refrigerating chamber is maintained at all times, thereby being capable of maintaining freshness of a stored foods for a long time.

Abstract: A method for scheduling a plurality of cells of a call via a connection linking a multiplicity of nodes which include a source node and a destination node is provided. A frame counter which counts down the time slots of each frame to be reset to a frame size is assigned to each node of each connection. All the frame counters at all the nodes are pre-synchronized on a connection basis based on propagation delays and delay bounds so that each upstream count of the frame counter in the upstream node is previously correlated to a downstream count of the frame counter in the downstream node. So the eligible time of a cell at each node can be determined without delivering scheduling information from an upstream node to a downstream node.

Abstract: A refrigerator has a blowing fan being capable of blowing bilaterally in a cool air duct. When a door is opened, the blowing fan blows to discharge cool air from the cool air duct, so the air curtain for shutting off a cooling compartment is generated. When the door is closed, the blowing fan blows to draw cool air in the cooling compartment into the cool air duct, so the circulation of the cool air is actively performed, and the cooling efficiency is enhanced.

Abstract: In a programmed computer system with a display device for preparing a working plan for inserting a plurality of materials into a printed circuit board, a method for transforming an original bill-of-material made by a material supplier into a standard bill-of-material is disclosed. In the method, the original bill-of-material is stored in a first storage area of the programmed computer system, and then field configuration information of the original bill-of-material is registered. Next, a bill-of-material transforming command is inputted, and then in response to the bill-of-material transforming command, material information of the original bill-of-material stored in the first storage area is transformed into the standard bill-of-material. Finally, the transformed material information is stored in a second storage area assigned as a standard bill-of-material area.

Abstract: A received television program is blocked out when a rating of the program is not within a scope of a preset rating. A rating signal is extracted from a video signal of the television program, and the rating signal is decoded to detect the rating of the program. The rating of the program is compared with the preset rating and an automatic frequency control (AFC) circuit is forced into an inoperative state to block out an output of the received television program when the comparison shows that the rating of the detected program is not within the scope of the preset rating. Accordingly, the blocking-out function against improper programs can be achieved by detecting the rating of the received program and by making the AFC circuit inoperative.

Abstract: In an optical pickup actuator, a lens holder has an objective lens and a penetrating hole for placing the objective lens. A pair of bobbins make contact with both side surfaces of the lens holder. A focusing coil and a tracking coil are wound around each of the bobbins in orthogonal directions to each other. A bottom plate spaced under the lens holder is installed. A pair of yokes are formed upwardly on the bottom plate at the outsides of the bobbins. A pair of magnets are formed on inside surfaces of the yokes for giving magnetic flux to the focusing and tracking coils. The magnetic flux has an effect only on some coil portion between the bobbin and the magnet, however it has no effect on another coil portion of the bobbin opposite to the magnet. The bobbins serve as internal yokes. A lens holder suspension part has a suspension supporting plate on the bottom plate and a suspension PCB fixed therewith.

Abstract: An apparatus deinterleaves decoded symbols and outputs the deinterleaved symbols in an appropriate form for external devices. In order to achieve the deinterleaving and outputting processes, the apparatus sequentially stores the decoded symbols in response to enable signals and produces output data of P bits based on the stored decoded symbols by using two memory groups which alternately perform the storing and the producing processes. The operations of the two memory groups are controlled by an input control block and an output control block. The input control block produces the enable signals to control the two memory groups to thereby sequentially store the decoded symbols to the two memory groups. The output control block selects one of outputs provided from the two memory groups and provides the selected output as the output data of P bits.

Abstract: The invention provides a method of defrosting a frost load accumulated on an evaporator, the method comprising the steps of: performing a normal mode for controlling ON-OFF operations of the compressor; sensing a temperature of the evaporator, comparing the sensed temperature with a first preset temperature to thereby determine a significant amount of frost; if the sensed temperature is less than the first preset temperature, removing the frost by activating the fan and the heater for a predetermined duration; determining whether or not the fan should be activated during the defrost mode, by sensing and comparing temperatures outside/inside the refrigerator, and a total number of instances of a refrigerator door opening and closing; checking whether or not the duration has elapsed, and if the duration has not elapsed, continuously activating the heater; and de-activating the heater if the duration has elapsed and performing the normal mode.
