Title: Method and apparatus for automatic punching
Inventor: YAZIMA TOSHIO
IPC: B23Q15/24
Filed: 1984-08-18
Granted: 1989-07-31
Abstract: The punching system uses a number of positioning marks, adjacent the components to be punched out, printed on the sheet metal and detected by a camera within the printing press, to allow the printed components to be positioned in the correct punching position.  The sheet is acted on by suction devices for moving it into contact with a stop which allows the position of the sheet to be corrected.  When an incorrectly printed component is detected its punching is prevented.  Pref. the incorrect printing is designated by a mark which is detected by an optical sensor.

Abstract: 본 발명 플라즈마 처리장치는 서셉터에 공급된 RF전류가 정전척의 도전체층에 유입되어 상기 도전체층과 접속되는 전압인가용 케이블에서 누설되는 것을 저감하여, 상기 도전체층에 RF전류의 유입을 저감시키므로서, 상기 정전척의 절연층의 파괴를 방지하는 것이다.  상기 플라즈마 처리장치는 저부에 개구부를 가진 접지전위가 되는 챔버와 상기 챔버내에 배치되어 고주파전력의 인가에 의하여 상기 챔버와의 사이에서 플라즈마를 발생시키기 위한 서셉터와, 상기 서셉터와 상기 챔버와를 절연하기 위한 절연부재와, 상기 서셉터상에 배치되고, 절연층의 사이에 도전체층을 개재시킨 구조를 가진 정전척과, 상기 챔버저부의 상기 개구부 주연에 일체적으로 착설되고, 단부가 하방을 향하여 연출된 통형체와, 상기 통형체내에 삽입되고, 선단이 상기 서셉터에 접촉된 통형 고주파 전력급전체와, 상기 급전체 접속된 고주파 전원과, 상기 급전체내에 동축적으로 삽입되고, 선단이 상기 정전척의 상기 도전체에 접속된 전압인가용 케이블과, 상기 케이블에 접속된 직류전원으로 구성되어 있다.

Abstract: The device minimizes a cell area by minimization of gap between gate electrode of transfer gate and control gate, and improves productivity. The device includes a process which forms serially EEPROM cell between stack gate and transfer gate, a process which forms a buried oxidation layer and n+ buried area, a prosess which forms a tunnel oxidation layer in a transfer gate, a process which forms a source and drain in both sides of stack and transfer gates, a process which forms control gate by reduction of EEPROM cell area, and a process which estends a buried oxidation layer and n+ buried area of stack gate to an one side of gate electrode.
