Abstract: Novel polymers are provided which are produced by recombinant techniques. The polymers are characterized by having a small repeating sequence which provides for strands capable of associating, resulting in useful structural characteristics, where the strands are joined by turns or loops which are flexible and available for interaction with the environment. Specifically, repeating groups of naturally occurring proteins such as silk are modified by introduction of an amino-acid sequence at a site which provides for a turn between strands to provide for readily available oligopeptides capable of interacting with molecules in the environment.

Abstract: 예컨대(8 x 8) 화소를 1 블럭으로 하고, 블럭마다 DCT 변환을 행하여 대역 압축을 행하고 DCT 변환 데이타의 2 차원 배열을 복수의 영역으로 분할하고, 각 영역마다 상이한 제수로 나눗셈하고 양자화할 때, 간단한 구성으로 나눗셈을 행할 수 있게 하고, 비용 절감과 처리의 고속화를 도모한다. 
     예컨대(8 x 8) 화소를 1 블럭으로 하고, 블럭마다 DCT 변환을 행하여 대역 압축을 행하고 DCT 변환 데이타의 2 차원 배열을 복수의 영역으로 분할하고 각 영역마다 상이한 제수로 나눗셈하고 양자화할 때, 제수를 2의 누승 또는 2의 누승에 2의 제곱근을 곱한 수로 설정한다. 이같이 하면 시프트 회로(53, 54, 55)와 가산 회로(52, 56, 57)로 나눗셈을 행할 수 있다.

Title: 감시용 텔레비젼
Filed: 1993-01-21
Granted: 2001-04-02
Abstract: [목적] 
     1 대의 수상기로 감시와 오락의 양기능을 갖춘 감시용 텔레비전을 제공한다. 
     [구성] 
     모자화면 제어회로(20)에는 비디오카메라(10)와 텔레비전튜너(30)가 접속되어 있고, 비디오카메라(10)의 촬영범위내에 인간이 없을 때에는, 감시범위의 풍경을 자화면으로 하는 동시에 텔레비전방송을 모화면으로 한 화상신호를 생성하여, 화상표시기(50)에 출력하고 있다. 
     비디오카메라(10)의 촬영범위내에 인간이 다가오면 이 인간이 발하는 적외선을 적외선검지장치 (40)의 적외선센서 (41)가 검지하여, 모자화면 제어회로(20)에 전환신호를 출력한다. 모자화면제어회로(20)는 이 전환신호가 입력되면, 비디오카메라(10)가 출력하는 화상신호를 모화면으로 하는 동시에 텔레비전튜너(30)가 출력하는 텔레비전방송의 화상을 자화면으로하여, 이제까지의 모자관계를 역전시킨다.

Abstract: The information recognition system performs telephone automatic dialing by recognizing the information of a namecard on the information sheet. The system includes: (a) memories (6,7) which store the external input data from keyboard (1) and I/O unit (3) as well as the data an from information recognition system (9); (b) a microprocessor (1) which displays the information from the memory in realtime as well as generates the information sheet; (c) an information sheet generator(4) which produces the information sheet, recorded in the memory, according to the control signal of the microprocessor; (d) a modem(10) which performs automatic dialing by using the phone number in the read-out data.

Abstract: 그리퍼 컨베이어는 그리퍼(3)로 제공되는 이동 컨베이어 체인(1)을 포함한다. 각각의 그리퍼(3)는 그 닫힌 위치쪽으로 그리퍼(3)를 경사지게 하는 스프링(36)과 선회 클램핑죠오(33)와 고정 클램핑죠오(31)를 포함한다. 컨베이어는 컨베이어 체인이 이동하는 동안에 선택된 그리퍼(3)를 여는 기능을 하는 여는 수단(40)을 포함하며, 각 그리퍼(3)의 선회 클램핑죠오(33)는 여는 수단(40)에 의하여 작동되는 작동아암(37)을 갖는다. 이동 클램핑죠오(33)는 선회 방향으로 제한된 자유선회운동을 위한 축(32) 상에 선회 가능하게 장착된다. 이동 클램핑죠오(33)의 무게 중심이 축(32)으로 부터 거리를 두고 배치되기 때문에 이동죠오(33)는 신문 등의 물품이 놓여져서 집혀지는 지지대 표면(N1, N11)과 인접하여 하부 방향과 외부 방향으로 흔들릴 수 있다. 이동 죠오(33)의 외부로 흔들리는 운동은 스프링(35)에 의하여 지지된다. 작동아암(37)은 집어지는 방향에 있는 그 단부 위치에 도달된 후 이동죠오(33)에서 떨어져서 외부로 흔들리도록 배열될 수 있다.
