| 20090236951 | SWITCHED RELUCTANCE MOTOR - The present invention relates to a switched reluctance motor which includes a housing, a stator and a rotor received and installed within the housing, and a rotor position detecting unit that detects a rotational position of the rotor at an outer side of the housing. Assembling can be quickly and easily performed, a sensor can be easily repaired and checked, and a bad influence on the sensor by temperature and dust can be reduced. | 09-24-2009 |
| 20090267548 | SWITCHED RELUCTANCE MOTOR AND CONNECTION METHOD FOR SENSOR SHUTTER THEREOF - The present invention relates to a switched reluctance motor and a connection method for a sensor shutter thereof. The switched reluctance motor in accordance with the present invention includes a stator; a rotor rotating with respect to the stator centering around a rotational shaft; and a sensor shutter having a sensing part through which a light can be passed and connected to an end portion of the rotational shaft, and a stopping ring is connected to the end portion of the rotational shaft so as to prevent the sensor shutter from being separated. Accordingly, the sensor shutter can be quickly and easily connected and the length of the rotational shaft can be decreased. | 10-29-2009 |
| 20100147012 | REFRIGERATOR HAVING DISPENSER - Disclosed is a refrigerator having a dispenser, including a main body having a cooling chamber and a door for selectively shielding the cooling chamber. The refrigerator also includes a container accommodating unit and a communication chute that passes through a front surface of the door and guides content to a dispensing cavity defined by the container accommodating unit. The refrigerator further includes an obstruction unit disposed in the container accommodating unit, and movable, about a plane perpendicular to the front which content guided by the communication chute is relatively obstructed by the obstruction unit and a second position in which content guided by the communication chute is relatively unobstructed by the obstruction unit. | 06-17-2010 |
| 20100321961 | INSULATION TRANSFORMER AND KEY INPUT CIRCUIT HAVING THE SAME - An insulation transformer and a key input circuit having the same are disclosed.
