Title: Process for making low optical density polymers and copolymers for photoresists and optical applications
Inventor: SHEEHAN MICHAEL T
IPC: G03F7/004
Filed: 1991-06-28
Granted: 1999-06-15
Abstract: Polymers comprising poly(4-hydroxystyrene) and/or substituted poly(4-hydroxystyrene) are produced by polymerizing 4-acetoxystyrene and/or substituted 4-acetoxystyrene monomers, with or without other comonomers, and subsequently performing transesterification. Preferably, the polymers are produced using at least one alcohol as a reaction medium, a chain transfer agent and a transesterification reactant. It is appropriate: to use an initiator which does not comprise a substantially absorbant structure over the 240 to 260 nm range or to use an initiator concentration of less than about 3 mole % of the monomer(s); to obtain a polymerization conversion of the initial polymerization monomers of at least about 90% by weight, or to remove residual monomer(s) from the reaction medium prior to transesterification; to obtain a transesterification conversion of the polymerized monomers of at least 85% by weight; and to avoid the use of transesterification catalysts which can cause the formation of chemical structures which can absorb over the 240 to 260 nm radiation wavelength range. The target polymers have low optical density (absorbance) over a wavelength range from 240 to 260 nm, as well as low optical density over the near UV and visible spectrum (310 to 800 nm); and are useful as photoresist components for use in combination with deep UV, X-ray, and E-Beam imaging systems.

Abstract: 본 발명은 프로젝션TV의 화상확대용 투사렌즈군이나 카메라의 줌렌즈군을 지지하는 렌즈경통에 관한 것으로서, 특히 선명화상을 얻는데 방해가 되는 난반사광을 소거하기 위한 다수의 톱니륜이 내경면에 형성되어 있는 난반사광소거용 렌즈경통에 관한 것이다. 본 발명에 따른 난반사광소거용 렌즈경통은, 광원으로부터의 공축선을 따라 상호이격배열된 다수개의 렌즈를 수용지지하며, 상기 각 렌즈에 의해 구분되는 적어도 2개의 내경면에 다수의 난반사광소거용 톱니륜이 배설된 렌즈경통에 있어서, 상기 광원으로부터 가까운 제1내경면에 배설된 톱니륜들은 상기 광원으로부터 보다 먼 제2내경면에 배설된 톱니륜들에 비해 큰 피치를 갖는 것을 특징으로 한다. 이에 의해 난반사광의 소거효율을 극대화함으로써 난반사광의 누출에 의한 화질저하를 방지할 수 있다.

Abstract: 칩내에 집적된 에프엠 검출기는 양호한 신호 대 잡음비를 얻기 위해 또는 충전 캐리어에서 열적 드리프트를 방지하기 위해 세라믹 필터 또는 LC회로와 같은 외부 컴포넌트를 가져야 한다. 본 발명의 목적은 에프엠 검출기의 내부 동작 조건을 세팅하는 외부 컴포넌트의 양을 줄이는 데 있다. 외부 컴포넌트는 전혀 이용되지 않았다. : 그 대신에 제어회로는 칩에 에프엠 검출기로 만들어졌다. 제어회로는 전류제어 발진기로 구성된다. 에프엠 검출은 특히 칼라 텔레비젼과 라디오 수신기에 이용된다.

Abstract: The method for controlling preheating function of a microwave oven at a low voltage comprises: a time comparing step of storing a preheating temperature at a microcomputer, turning on a heater and a time counter and comparing the counted time of the time counter with a predetermined preheating time; a preheating ending step of completing the preheating if the temperature in the heating room reaches the preheating temperature in a predetermined preheating time; an error mode performing step of displaying an error if the preheating temperature does not reach a predetermined level after lapse of the predetermined preheating time; and a preheating completing step of checking the open of a door after the preheating ending step, turning off the heater if the door is open and processing to a next step.
