Abstract: 본 발명은 승강기를 소정의 목적층으로 이동시키는 승강기 구동시스템의 제어방법에 관한 것으로써, 복수의 목적층을 입력하는 단계와, 상기 복수의 목적층으로부터 동일한 목적층을 판단하는 단계와, 상기 판단에 기초하여 적어도 하나의 목적층을 해제하는 단계를 포함한다. 
     따라서, 승강기의 내,외부조작보턴을 잘못 조작하여 탑승자의 의도와는 다른층에서 승강기가 정지하여 문이 개폐됨으로써 발생하는 전기의 낭비와 시간의 낭비를 절감할 수 있도록 된 것이다.

Abstract: PURPOSE: A method for fabricating a PDP(plasma display panel) is provided to reduce the fabrication process time of the PDP by reducing the dandification process time of a transparent substrate. CONSTITUTION: A method includes the steps of depositing a metal thin film(20) on a transparent substrate(11) using a sputtering apparatus and performing a densification process by curing the transparent substrate where the metal thin film is deposited. The metal thin film is formed with a Cr or Ti with a thickness ranging from about 0.1 to 1.0 micrometers. And it is desirable that the light reflectivity and the thermal conductivity of the metal thin film is higher than the transparent substrate.
