Granted: 1990-07-30
Abstract: Gas is entrained in a liq. stream and projected from a nozzle into a flow straightening tube. The tube is convergent in a downstream direction and has a discharge orifice greater than that of the direction and has a discharge orifice greater than that of the nozzle. Pref. the ratio of the nozzle diameter to that of the discharge orifice is 0.1-0.5 and the overall length of the flow straightener is 20-100 times the diameter of the nozzle. The aerator may be used in conjunction with a tank which is used for the biological treatment of waste water. The aerator reduces the coalescence of the bubbles to increase the oxygen dispersion efficiency.

Abstract: 이 발명은 16 : 9 화면사이즈의 와이드 텔레비전에 있어서, 4 : 3 화면비(Aspect Ratio)를 갖는 영상정보를 시간압축하여 또는 시간압축없이 16 : 9의 와이드 TV에 디스플레이할 수 있도록 한 와이드 텔레비전의 신호처리회로에 관한 것이다. 
     이 발명은 16 : 9의 와이드 스크린에 4 : 3화면비의 영상신호를 디스플레이시 라이트 클럭과 리드클럭을 달리하여 시간압축을 행함으로써 신호압축을 위한 회로가 별도로 필요치 않게 되며, 이에 따라 회로가 간단해질 뿐만아니라 제품의 가격면에서도 보다 유리하게 되며, 또한 색차신호처리시 멀티플렉싱하여 시간압축처리하고 후에 다시 디멀티플럭싱하는 방법을 사용함으로써 보다 효율적으로 색차신호를 처리할 수 있게 된 것이다.

Abstract: 본 발명은 1/4공통 교환포멧(QCIF)을 공통교환 포멧(CIF)으로 변환하는 장치에 관한 것으로 특히 QCIF형태의 로우분해(Low reso-lution) 영상신호를 하이분해의 CIF형태의 영상신호로 변환하여 비디오 코덱시스템에 적용하기에 적합하도록 한 영상신호의 포멧변환장치에 관한 것이다. 
     이를 위하여 본발명은 영상신호 포멧인 QCIF형태의 영상을 CIF형태의 영상신호로 하여 상대적으로 고화질을 유지토록 함과 동시에 하드웨어적인 처리량을 경감시킬 수 있도록 함으로써 종래기술의 문제점을 개선코자 한 것이다.

Title: Address circuit for graphic control circuit
Inventor: KIM DAE-HYON
IPC: G06F3/14
Filed: 1992-12-30
Granted: 1995-02-27
Abstract: The circuit increases automatically the address when the consecutive addresses are used in implementing the graphic. The address auto-increment circuit comprises a CPU, an address controller, a FIFO controller, a memory, a flip-flop outputing auto signal to the address controller. The address controller comprises an address register, a timing generator, a loading counter. When data are stored in consecutive addresses, CPU write only initial address. Whenever the CPU store data in the FIFO, address increases automatically.

Title: Three laser optical disk drive system
Inventor: GOLDSMITH PAUL
IPC: G11B7/13
Filed: 1990-12-12
Granted: 1999-07-15
Abstract: An erasable optical disk drive system is disclosed which utilizes an electron trapping media coated on the disk surface to store data in the form of light energy and which utilizes three laser beams, each having a wavelength range distinct from each other as well as distinct from the wavelength range of the emission produced by the impingement of the read laser onto the electron trapping media. Data is written onto the disk, which is contained in a light-tight contamination-free environment, using a visible light laser beam. Data is read from the disk and the disk is erased by using a near infrared light laser beam. The focus and tracking functions of the disk drive system are accomplished by using a laser beam having yet another range of wavelengths, which are greater than those of the visible light laser beam and those of the photon emission from the electron trapping optical memory media, but less than those of the read/erase laser.
