Abstract: The fuel injection system has a reference mode operating during starting. This provides a programmed amount of fuel without any risk of excessive exhaust emission. The programmed mode operates until the processor detects normal running. The fuel injection operates via a solenoid valve (20) which opens during the pressure pulses of the mechanical fuel pump. The starting mode operates as a series of opening pulses with the total opening time shorter than the pump pressure pulse. During normal engine running the injection pulses are computed with respect to torque, engine temperatuer, throttle setting etc.

Title: Tampon
Inventor: SHIMATAMI KATSUO
IPC: A61F13/20
Filed: 1988-09-05
Granted: 1992-09-07
Abstract: This invention relates to a sanitary tampon prepared by forming strings from a menstrual blood absorbing material having high water absorptivity, such as absorbent cotton, weaving the strings to form a tampon base material and compressing a tampon body formed from this base material by applying thereto an external force in a bullet-like shape. This tampon has a large surface area and a large number of voids formed by the stitches. Therefore, it can efficiently absorb the blood when used, and each of the strings absorbing the blood rapidly swells independent of the others so that they return to a state before the compression and can reliably absorb the blood flowing down along the vaginal wall. The tampon can be taken out easily because the stitches of the tampon body are crushed by the inner wall of the vaginal opening and its surface area becomes small.

Title: Combustion control method for gas boiler
Inventor: LEE HWANG-UI
IPC: F24H9/20
Filed: 1991-04-29
Granted: 1993-10-15
Abstract: The method drives the 3-way valve and controls the combustion in the gas boiler, specially  in  the  case  of  changing  a  room heating mode into  a  water-warming  mode  while  in  winter  mode operation. The method dilutes the hot water within a  second  heat exchanger with the lower temp. water within a pipe, so that it can enhance warm water usability.  The  method  comprises  a  step  of managing to direct the 3-way valve for  warm  water  although  the water flow switch is off; a step of  preventing  the  warm  water, remained in the second  heat  exchanger,  from  rising  to  higher temperature.

Abstract: 관중석과 상영자석에 상영정보를 디스플레이 하는 동안 상영이 이루어질때, 상영의 처리과정을 지원하기위한 상영자석 부가 정보를 관중석에 보이지 않고 상영자석에만 나타난다. 
     관중석에 화면정보가 나타날때 상영자석에도 나타나며 화면 정보는 축소된 후 디스플레이 된다. 
     상영이 다수의 스크린을 이용하여서 되고 상영정보가 스크린 중 하나에 디스플레이 될때 상영정보는 분배 결정기능에 의해 스크린중 하나에만 나타난다. 
     그 결과 상영자에 의한 상영의 처리과정이 원활히 진행될 수 있다.

Title: Cmos inverter and manufacturing method of the same
Inventor: LEE YONG-HUN
IPC: H01L27/04
Filed: 1991-06-13
Granted: 1993-08-25
Abstract: The CMOS inverter is prepared by forming a second  conductive type well on some part  of  a  first  conductive  type  substrate, making the first  oxide  film  on  the  drain  area  respectively, forming an  epitaxial  layer,  implanting  the  second  conductive impurity on the formed well, forming source and drain of the first conductive type on the first oxide film, forming source and  drain of the second conductive type at  the  first  oxide  film,  making gates between source  and  drain  of  the  first  and  the  second conductive types, coating all area with the second oxide  film  to form contact and wiring.

Abstract: 본 발명은 플라즈마광의 강도 변화에 따라서 플라즈마 처리의 종점을 정확히 검출하는 플라즈마 장치에 대한 것이다.  플라즈마 처리부는 플라즈마 발생부에 의해 발생된 플라즈마를 이동시켜 피처리 물질에 대한 플라즈마 처리를 실행한다.  센서부(30)는 플라즈마 처리부에 의해 플라즈마 처리가 실행될 때 플라즈마 중의 예정된 파장을 갖는 플라즈마 강도에 대응한 전기신호를 출력한다. 
     평활화부(40)는 수광센서로 부터의 전기신호를 평활화한다.  종점 검출부(50)는 상기 평활화부에서 평활화된 신호에 따라서 상기 플라즈마 처리의 종점을 검출한다.

Title: Organic waste treating method using earthworm
Inventor: SO CHUN-SHIK
IPC: C02F3/32
Filed: 1991-10-02
Granted: 1992-08-14
Abstract: Organic wastes from daily life, livestock industry  or  other industries are treated by feeding the  organic  wastes  containing 30-90 wt.% water to earthworm at 10-35  deg.C.  The  excretion  of earthworm after digesting organic wastes,  which  is  composed  of fine  particles,  can  increase  air  permeability  of  soil   and absorptivity of water, and also it can be used as soil conditioner or organic fertilizer since it has a lot of fertilizer components, microorganisms and enzymes.
