Abstract: 기록/재생을 동시에 수행할 수 있도록 된 광섬유를 이용한 광학식 기록/재생장치가 개시되어 있다. 
     이 개시된 장치는 고정드럼과; 이 고정드럼과 동일 회전축 상에 회전가능하게 설치되는 회전드럼과; 회전드럼에 소정간격으로 설치되어, 회전드럼 외주면에 접촉주행하는 기록매체에 대해 정보의 기록/재생을 수행하는 다수의 광학헤드와; 광다중분파회로에 접속외며, 광학헤드 각각에 연결된 다수의 광섬유를 구비하며, 상기한 광학헤드는 소정 간격으로 이격 설치된 기록전용 광학헤드와 재생전용 광학헤드로 분리형성되여, 기록매체에 정보의 기록과 재생을 동시에 수행할 수 있도록 된 것을 특징으로 한다. 
     따라서, 기록매체에 정보가 올바르게 기록되고 있는지의 여부를 기록과 동시에 확인할 수 있다.

Abstract: 본 발명은 부배열과 연결된 용장 종렬들을 포함하고 다수의 입력/출력 단자가 판독 및 기록 사이클에서 부배열내 다수의 종렬과 통하게 되어있는 집적회로 메모리에 관한 것이다. 부배열 한 개당 용장 종렬의 수는 입력/출력 단자의 수보다 적다. 멀티플렉서는 선택된 용장 종렬을 교체된 종렬과 연결되어 있는 입력/출력을 위해 선택된 센스 증폭기 및 기록 회로에 접속시킨다. 멀티플렉서는 용장 종렬의 비트라인과 접속된 패스게이트 및 각 패스게이트와 용장 종렬에 대한 선택성을 갖는 각 센스/기록 회로 사이에 접속된 퓨즈를 포함한다. 선택된 입력/출력과 연결되지 않은 퓨즈들은 개방되고 선택된 입력/출력과 연결된 퓨즈들은 그대로 있게된다. 프리차아지 트랜지스터는 패스 게이트가 꺼진 후 각 부동 노드를 프리차아지시키기 위하여 패스 게이트의 퓨즈측에 접속된다. 이같은 프리차아지는 퓨즈가 개방되는 라인에 대한 패스 게이트의 퓨즈측에 포획될 수 있는 임의의 전하의 효과를 무효화시키기 때문에, 다음 사이클의 호출시간에 손상을 입히지 않는다.

Title: Method of searching calculation on database management system
Inventor: LEE KIL-HAENG
Filed: 1991-12-23
Granted: 1994-08-25
Abstract: generating information necessary for real time retrieval; obtaining a physical start address of a tuple; checking whether a relative order value of the tuple exists within the range of a corresponding relation, if it does not exist, reporting an error, and if it exists, checking whether there is a tuple to be retrieved; and if it does not exist, reporting an error, and if it exists, copying the tuple and reporting a retrieval result, thereby shortening a retrieving time.

Title: 시각 신호수단을 구비한 공기청정장치
IPC: B65D85/00
Filed: 1992-01-14
Granted: 1998-07-01
Abstract: 본 공기청정장치는 이 장치내에 포함된 공기청정용 방향 조성물의 소모시기를 지시해준다. 본 장치는 동일하거나 상이한 방향 조성물을 포함하는 다수의 체임버를 구비하고 있다. 이 체임버의 내부벽들은 방향 조성물과 관련하여 대비색으로 착색된다. 따라서, 착색된 내부벽들은 해당 체임버내에 있는 방향 조성물이 소모되었음을 사용자에게 지시해준다. 본 장치에 있어서 다중 체임버의 특징은 방향 조성물의 다양한 선택을 가능하게 해주며, 그와 동시에 장시간동안 방향 조성물의 향기가 발산된다는 점이다.
