Abstract: PURPOSE: A video data interpolation device for switching a direction of interpolated pixel data is provided to transform vertical processing pixel data to horizontal processing pixel data. CONSTITUTION: A video data interpolation device for switching a direction of interpolated pixel data comprises a memory group(100), an interpolation filter(200), a shift register(300), a control portion(500), and a filter memory group(400). The memory group is formed with data memories of n number for storing parallel video data of n number. The interpolation filter outputs directly interpolated video data from the input video data of n number. The shift register shifts and stores the interpolated data of each n clock period toward a first direction and shifts and outputs the stored interpolated data of n number toward a second direction. The control portion outputs an address control signal for reading sequentially the interpolated data toward a vertical direction and a control signal for shifting the interpolated data toward the first and the second directions. The filter memory group is formed with filter memories of n number for storing the interpolated data of n number shifted toward the second direction.

Abstract: 본 발명에 따르면, 세탁 겸용 탈수조내에 넣은 세탁물을 세탁하는 세탁기에 있어서, 세탁 겸용 탈수조내의 세탁물에 교반 날개 등에 의한 기계력을 부가하는 일 없이 세탁액을 순환시킴으로써, 세탁물을 손상시키거나 엉키게 하는 일 없이 세탁할 수 있도록 한다. 
     물받이조(12)내에 세탁 겸용 탈수조(10)를 회전 가능하게 배치하고, 물받이조(12)의 상방을 물받이 덮개(23)로 덮고, 세탁 겸용 탈수조(10)를 모터(13)에 의해 회전 구동함에 의한 펌프 작용에 의해, 세탁 겸용 탈수조(10)와 물받이조(12) 사이의 세탁액을 세탁 겸용 탈수조(10)와 물받이조 덮개(23) 사이로부터 세탁 겸용 탈수조(10)의 대략 중심 방향을 향하여 토출시킨다.  물받이조(12)와 물받이조 덮개(23) 사이에 스폰지재, 고무재 등의 패킹 부재(27)를 개재하여 물의 유출을 차단하는 구성으로 한 것이다.
