Abstract: PURPOSE: A method for searching a position in a vehicle navigation system is provided to minimize a remote controller operation when performing a position search of the vehicle navigation system. CONSTITUTION: In a method for searching a position in a vehicle navigation system, position memo function of a displayed total menu is selected(200). If the position memo function is selected through a remote controller, a position menu window is opened at a thin film transistor liquid crystal display(TFT LCD). If the position menu window is opened, a user selects one of address, building and a registration position searching methods(204,206,208) each for searching a position by use of the remote controller. If the address searching method is selected, a 'city' list is displayed on the TFT LCD(210). If the 'city' list is displayed, the user selects by shifting a highlight into a desired 'city' position(212). After selecting the city, a message is outputted which is to direct an input of a consonant of a 'dong' to which a desired building belongs. The user inputs the consonant of the 'dong'(214), and a desired 'dong' is selected(216).

Title: 온수정화장치
IPC: B01D35/027
Filed: 1999-05-08
Abstract: 조립이 간단하고 부품사이의 호스접속 시간이 절약되며, 여과재의 세정도 용이하게 행할 수 있는 온수정화장치를 제공하는 것을 과제로 한다. 
     히터부(9)와 살균부(10)와 정화부(11)와 순환펌프(16)를 구비하고 있으며, 상기 히터부(9)와 살균부(10)와 정화부(11)가 하나의 내부케이스(8) 내에 조립되어 있는 것을 특징으로 한다. 바람직하게는 상기 정화부(11)에 있어서의 여과재가 전체면으로 물이 통과 가능한 바스켓용기에 충전되어 있고, 상기 바스켓용기가 상기 정화부(11)에 대하여 붙이고 떼기 가능하게 되어 있으며, 또한 상기 히터부(9)의 상부와 하부 및 상기 정화부(11)에서 나가는 배수로(15) 내에 수온센서(21∼23)가 배치된다.
