Abstract: PURPOSE: An inexpensive refrigerator is provided in which the inner volume of a storage compartment is increased. CONSTITUTION: The cooler (16) of refrigeration cycle is disposed at a rear part in a refrigeration compartment (15). A fan (26) is disposed in front of the cooler (16). When it is operated, air is blown from the fan (26) to the cooler (16) to produce chill which flows through the cooler (16) into a supply duct (20). Since a chill passage for guiding chill from the cooler (16) into the supply duct (20) is simplified, the chill passage can be formed of a single insulator (18) and thereby the inner volume of the storage compartment can be increased while reducing the cost.

Abstract: 본 발명은 브라운관용 편향요크 구동회로에 관한 것으로서, 상기 1, 2차 4극 컨버젼스 요크부에 전류를 인가하기 위해 직렬 연결된 수직편향코일부및 보정회로부와 연결된 트랜스포머 1차부와, 전파 정류된 전류를 인가하기 위한 다이오드와 병렬로 연결하여 상기 1, 2차 4극 컨버젼스 요크부에 직렬 연결된 트랜스포머 2차부 및 상기 2차 4극 컨버젼스 요크부와 연결한 후 접지시키는 중간부로 구성함으로써, 수직편향부의 임피던스에 거의 영향을 주지 않아 수직편향부의 감도 변화가 거의 없고, 회로의 구현이 간편함에 따라 재료비를 절감시킬 수 있으며, 구동회로를 동작시키기 위한 전압이 필요치 않아 생산성을 향상시킬 수 있는 효과를 갖는다.
