Title: Locking device for vtr
Inventor: CHO SUNG-JE
IPC: G11B15/087
Filed: 1987-09-17
Granted: 1990-09-27
Abstract: The start and parental lock (PL) signals are recorded on the begining part of the video tape prohibited to show to yound people. When replaying the tape, a tape begining detector (10) and PL signal detector (20) detect the signal. If the PL signal is not detected, a microprocessor (30) requests to input the secret number and cutsoff the video switch (50) not to display the scene. If the start signal is not detected, the microprocessor determines that the tape is replayed at the middle and cuts off the switch. But if the start signal is detected but the PL signal is not, then the microprocessor presumes that the tape is allowed to the young people and continues the replay.

Abstract: forming a field oxide film for separating an active region and an inactive region; forming a silicon nitride film on a semiconductor substrate including a transistor formed on the active region thereof; forming a silicon film(BPSG) including boron-P on the entire surface of the silicon nitride film; planarizing the surface of the silicon film; forming a contact window for connecting a source of the transistor and a first electrode of a capacitor; and forming the first electrode of the capacitor by depositing a conduction material over the resulting structure and patterning it. The memory cell of increased capacitance is manufactured with simplified process.

Title: 반사 굴절 축소 대물 렌즈
IPC: G02B13/14
Filed: 1992-02-08
Granted: 2001-05-02
Abstract: 본 발명은 오목 거울과 빔 분산기 사이에 배치되는 부가적인 렌즈군없이 오목 거울, 빔 분산기와 여러 렌즈군으로 구성되는 빛의 반사와 굴절 축소 렌즈에 관한 것이다. 빛의 반사와 굴절 축소렌즈는 1 : 4의 이미지 치수용으로 0.52 ∼ 0.58의 이미치 측면구경을 갖는 것으로 개시되어 있으며 서브미크론리쏘그래피(submicronlitso graphy)에서 사용되는 제한되지 않은 엑시머레이저용으로 수정된다.

Title: Network interface board
Inventor: KIM IL-YONG
IPC: H04L12/12
Filed: 1992-04-10
Granted: 1995-10-16
Abstract: The network interface board is set by a software and an additional simple instead of jumper setting. The board includes a flip-flop for sending memory window address and interrupt signal to PA1 and a decoder respectively, a control logic for generating control signal to control power supplied to transmission media according to transmission media selection signal, and a DC power supply controlled by the control signal generated by the control logic.
