Title: 이온주입기에서 이온빔을 가변적으로 포커싱하고 또한 질량분해를 위한 가속기-감속기 정전렌즈
IPC: H01J37/12
Filed: 1998-04-28
Abstract: 이온주입시스템(10)에서 사용을 위한 정전렌즈(36)가 제공된다. 렌즈는 터미날전극(37)과 그리고 억제전극(38) 및 분해전극(39)을 포함하는 조정가능한 렌즈 서브어셈블리(40)를 포함한다. 렌즈 서브어셈블리는 빔이 제1(분산)면에서 최소 웨이스트를 가지는 터미날전극 근처에 위치된다. 그러한 위치시킴은 전극 사이에 필요한 갭을 최소화시켜, 따라서 감속모드의 동작에서 빔 블로우-업과 전자공핍영역을 최소화시킨다. 억제전극과 분해전극은 각각 갭(d38, d39)에 의해 분리되는 제1 및 제2부분(38A 및 38B, 39A 및 39B)을 가진다. 이동매카니즘(60, 62)은 갭(d38, d39)을 조정하기 위하여, 억제전극과 분해전극의 제2부분(38B, 39B)을 향해 또는 멀어지도록 억제전극과 분해전극의 제1부분(38A, 39A)을 이동매카니즘(60, 62)이 동시에 이동시킨다. 조정가능한 렌즈 서버어셈블리(40)는 (ⅰ) 감속모드의 동작시에 상호간에 직교하는 (분산 및 비-분산)면에서 빔을 포커싱하는 한편, (ⅱ) 감속모드의 동작(포커싱이 덜 중요함)시에 분산면에서 가변 질량분해를 허용함으로써 터미날전극(37)에 의해 출력된 빔을 조정한다. 일반적으로, 분해전극(39)간의 갭(d39)은 가속모드의 동작시에 분산면에서 조정가능한 질량분해를 허용하도록 조정된다. 감속모드의 동작시에, 갭(d39)의 조정은 조정가능한 분산면 포커싱을 제공하는 한편, 억제전극(38)의 전압은 조정가능한 비-분산면 빔포커싱을 허용하도록 조정된다.

Abstract: PURPOSE: A lubrication mode setting method for a compressor of an inverter refrigerator is provided to reduce a noise while allowing the lubrication to be performed at a frequency lower than the resonance frequency band. CONSTITUTION: A method includes a first step of setting a lubrication mode start and stop frequency, lubrication time, and a resonance frequency band at an early stage of the operation and determining whether the lubrication mode start frequency is reached, a second step of starting the lubrication by varying a speed increasing rate into a predetermined angle and determining whether a predetermined lubrication time has lapsed if the lubrication mode start frequency is determined as reached in the first step, and a third step of setting a current operation frequency by sensing the interior temperature of the refrigerator and switching into a normal operation if the lubrication time is determined as lapsed in the second step.
