Claims (1)

서어미스터의 전식과 경시변화를 방지하도록함에 있어서 서어미스터(Th)의 양단에 정. 부(正. 負)사이의 전위치가 일정하게 교번되는 교류 전압을 인가하도록 하는 것을 특징으로 하는 서어미스터의 전식 및 경시 변화 방지 방법.Fixed at both ends of the thermistor (Th) in order to prevent thermistor transfer and change over time. A method of preventing the change of electrical and temporal changes in a thermistor, characterized by applying an alternating voltage in which all positions between negative electrodes are constantly alternated. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
