20110298518 | PHASE INTERPOLATION CIRCUIT SUITABLE FOR WIDE RANGE FREQUENCY INPUT AND OUTPUT CHARACTERISTICS STABILIZING METHOD THEREOF - A phase interpolation circuit includes a waveform shaping unit and a phase interpolator. The waveform shaping unit adaptively waveform-shapes first or second phase offset input clock signal pair that is applied, to output first and second buffered clock signals having a rising time and falling time each of more than about a quarter of a period of the first and second offset input clock signals. The phase interpolator is applied to generate a phase interpolation clock signal selected from phases between the first and second buffered clock signals in response to a weight value of a phase interpolation control signal. | 12-08-2011 |
20120327974 | SPREAD SPECTRUM CLOCK GENERATORS AND ELECTRONIC DEVICES INCLUDING THE SAME - Spread spectrum clock generators and electronic devices including the same are provided. An electronic device may include a memory and a first circuit block configured to output a first spread spectrum clock signal and a first address for accessing the memory. The electronic device may include a second circuit block configured to operate in response to a second spread spectrum clock signal, and configured to output a second address for accessing the memory. The electronic device may include a spread spectrum clock signal generator configured to receive the first spread spectrum clock signal to generate the second spread spectrum clock signal. The memory may be configured to compare the first and second addresses to each other to output a clock generator control signal corresponding to a difference between the first and second addresses. | 12-27-2012 |

20100122548 | REFRIGERATOR RELATED TECHNOLOGY - Disclosed is a refrigerator including a refrigerator main body having a cooling chamber. The refrigerator also includes a refrigerating chamber door positioned at the refrigerator main body and configured to open and close at least a portion of a refrigerating chamber. The refrigerator further includes an ice chamber disposed at an inner surface of the refrigerating chamber door containing ice. In addition, the refrigerator includes a door basket configured to be attached to an outer surface of the ice chamber and having a non-contact to portion positioned at a surface facing the ice chamber. | 05-20-2010 |
20100251744 | REFRIGERATOR HAVING ICE MAKING ROOM - A refrigerator is provided. The refrigerator includes a refrigerator main body including a cooling chamber, a door for opening or closing the cooling chamber, an ice making chamber located at the door, a sub-chamber located at the door and spaced from the ice making chamber, the sub-chamber being configured to receive cool air from the cooling chamber, and a cold energy transfer unit configured to transfer energy of cool air of the sub-chamber to the ice making chamber. | 10-07-2010 |
20100257877 | REFRIGERATOR RELATED TECHNOLOGY - A refrigerator and its operation method are disclosed. Cool air ducts guide cool air from a freezing compartment to an ice compartment that is positioned at a refrigerating compartment door. At least a portion of the cool air ducts are located at a barrier that separates the freezing compartment and the refrigerating compartment. | 10-14-2010 |
20100287959 | ICE MAKER, REFRIGERATOR HAVING THE SAME, AND ICE MAKING METHOD THEREOF - An ice maker, a refrigerator including the ice maker, and an ice making method are provided. The ice maker includes a tray having a predetermined depth into which water is supplied to make ice. The ice maker includes an elevating unit to elevate a portion of the ice, and a cutting unit to cut off the elevated portion of the ice to be dispensed as ice pieces to a user. The ice maker has a slim configuration, and a compact size. The ice maker may be provided in the door of the refrigerator at a height approximately the same as the height of the dispenser located at the front side of the door. This arrangement permits a path for supplying cool air from a freezing compartment to the ice maker to be decreased. | 11-18-2010 |
20100319366 | ICE MAKER, REFRIGERATOR HAVING THE SAME, AND ICE MAKING METHOD THEREOF - An ice maker, a refrigerator including the ice maker, and an ice making method are provided. The ice maker includes a tray having a predetermined length into which water is supplied to make ice. The ice maker is configured to mechanically separate the ice from the tray by using pistons which are driven by a motor. This permits the ice maker to have a reduced size, and occupy a small area, thereby implementing a slim configuration of a refrigerator. Furthermore, since an installation height of the ice maker is lowered, a path for supplying cool air may be shortened. This arrangement prevent loss of cool air being supplied to the ice making chamber. | 12-23-2010 |
20100319367 | ICE MAKER, REFRIGERATOR HAVING THE SAME, AND ICE MAKING METHOD THEREOF - An ice maker, a refrigerator including the ice maker, and an ice making method are provided. The ice maker includes a tray having a predetermined length and to which water is supplied to make ice. The ice maker is configured to mechanically separate the ice from the tray by using pistons which are driven by being pressed by structures. This allows the ice maker to have a reduced size, and a small occupation area, thereby implementing a slim configuration of a refrigerator. Furthermore, since an installation height of the ice maker is lowered, a path for supplying cool air may be shortened. This may prevent loss of cool air being supplied to the ice making chamber. Since the ice maker has a simplified configuration and precise operation controls, the fabrication costs may be reduced, and inferiority of the ice maker due to malfunctions may be prevented. | 12-23-2010 |
