Abstract: 스위칭 모드 전원 제어기(60)를 갖는 텔레비젼 수신기에 있어서, 이 제어기는 편향 등기화되어 전력 변압기(X1)에 펄스를 발생시킬 수 있다. 시동시 제어기에 전력 공급하기 위해서, 내부 전원이 시동되기 전에 제어기의 전원 입력상의 저장 커패시턴스(C5)는 AC 메인의 제1극성 위상 동안 저장 커패시터를 충전시키기 위해서 AC 메인(22)으로부터 정류된 전압에 전류 제한 저항(R2,V1)을 통하여 결합된다. AC 메인에 대한 텔레비젼 수신기의 초기 접속후 전력 소모를 감소시키기 위하여, 전류 제한 저항은 가열시 임피던스를 증가시키는 + 온도 계수(PTC) 요소(V1)를 포함한다. 아울러, 다이오드(D7)는 AC 메인의 대향 극성 위상시와 같은 극성으로 커패시터를 충전시키기 위해 저장 커패시터에 전류 경로내에서 결합된다. 커패시터 충전용 두 경로는 전류 제한 저항(R2,V1)에 대해 비교적 작은 값을 허용하는데, 이 저항은 저장 커패시터(C5)에 결합되어 남아 있으며 전력 메인 전압의 광범위에 걸쳐 과도한 전력 소모 없이 제어기(60)에 충분한 전력을 제공한다.

Abstract: PCT No. PCT/DE91/00502 Sec. 371 Date Dec. 29, 1992 Sec. 102(e) Date Dec. 29, 1992 PCT Filed Jul. 18, 1991 PCT Pub. No. WO92/01287 PCT Pub. Date Jan. 23, 1992.An arrangement with self-amplifying dynamic MOS transistor storage cells has in each case a MOS selection transistor AT, whose gate is connected to a word line WL, and an MOS storage transistor ST at whose gate a capacitor C for charge storage acts. This self-amplifying storage cell can be written on and read out with only one bit line BL and one word line WL. The two transistors AT and ST are connected in series and a common drain source region DS is connected via a voltage-dependent resistor VR to the gate electrode GST of the control transistor. The advantages reside in the fact that the cell geometry can be scaled without at the same time the quantity Q of charge which can be read out on the bit line BL having to be reduced, in that the quantity Q of charge which can be read out is larger than a charge stored in the capacitor C which acts at the gate of the storage transistor ST and in that the two MOS transistors AT and ST can be produced relatively simply.

Title: Method of porous silica glass and its apparatus
Inventor: JANG KAM-YONG
IPC: C03C1/00
Filed: 1993-12-28
Granted: 1996-05-17
Abstract: The porous silica glass showing no crack is manufactured by the step of (a)preparing the glass-formation solution obtained from hydration and condensation reaction of metal alkoxide, (b)forming the molding compd. by mold casting when the viscosity of the obtd. solution became 200-300 cps, (c)gelate the molding compd. by gelation apparatus of Fig. 1 that consists of heater, ammonia gas, and nitrogen gas injection instrument, (d)drying the gelled compd. by liq. carbon dioxide supercritical drying process. This manufacturing method can shorten the gelation time and lastly the manufacturing time, and can increase the yield rate and strength of porous silica glass.

Abstract: 클록 속도가 빠른 CPU 와 CPU 보다 속도가 늦은 메모리를 단일 클록으로 동작시킴으로써 시스템을 복잡화시키지 않고 고속 CPU 시스템에 대응할 수 있는 기억 장치를 실현한다. 
     셀어레이를 2개의 뱅크로 나누고, 마스크가 걸리는 CLK 신호에 동기하는 액세스용의 신호를 발생하는 타이밍 제너레이터를 구비하고, DQ버퍼나 레지스터를 개재하여 2 개의 뱅크의 셀어레이의 컬럼계를 파이프 라인 동작시킴으로써 2 클록으로 1 회, 코어부와의 사이의 액세스를 실시하고, 리드 모드시는 코어부로 부터 독출한 데이타를 4 비트 길이의 시리얼 레지스터에 2 비트씩 인터리브하여 전송하고, 시리얼 레지스터에 전송한 데이타를 시리얼에 출력시키고, 라이트 모드시는 시리얼 레지스터에 차례로 데이타를 취입하고, 취입한 데인타를 2 비트씩 인터리브하여 코어부에 기록한다.
