Abstract: The circuit provides the proportional viscous friction force to the speed of the object which is robust to the disturbance and being able to adjust the reference value. When the refence (Rf) for the determined viscous friction force is applied to a section switch (SW), the difference signal (e) between the reference and the present viscous friction force is multiplied by a control function (Cs). The control signal (U1) is amplified on a voltage amplifier (9) and supplied to a driver (10) which provides the actual viscous friction force (Cf). The code and magnitude of the output is adjusted to be the same as the reference (Rf) by a control circuit (8) and the voltage amplifier (9).

Title: Expression vector & gene for inf-alpha
Inventor: JO JUNG-MYONG
IPC: C12N15/21

Granted: 1994-02-19
Abstract: A cDNA of alpha interferon was prepared by reverse transcriptase from total RNA of animal cell KG-1 (ATCC CCL246). The cDNA was treated with restriction enzyme EcoRI, XhoI and cloned into a phage vector Uni-ZAPXR. A recombinant vector containing alpha interferon gene was screened for the cDNA library by a antibody for alpha interferon. After sequencing of the cloned alpha interferon gene, the alpha interferon gene was subcloned into a yeast plasmid pYLBC-GAP-HGH (KFCC-10669). The resultant expression vector was designated as Luck-α-IFN-1Y (KFCC 10715). Saccharomyces cerevisiae DC04 was transformed with the expression vector and a transformant carrying the expression vector was screened. The gene products from the transformant were determinated by SDS-PAGE.

Abstract: 욕조의 성형방법과 모울드를 설명하였음. 이 모올드는 모울드 수용기의 모울드수용기표면에 부착되는 인서트를 포함한다. 모올드수용기는 마무리면과 비마무리면을 갖는 동체를 수용한다. 동체는 동체의 비마무리면과 모올드수용기의 표면사이에 공간을 남기고 모울드수용기안에 배치된다. 인서트는 동체와 모울드수용기 표면사이의 공간의 일부의 단면적을 감소시키도록 모울드수용기 표면사이의 공간의 일부의 단면적을 감소시키도록 모울드 수용기의 표면에 부착된다. 수형모울드는 동체의 마무리면과 결합되어 동체를 모울드 수용기에 밀봉유지한다. 고분자 발포체는 모울드 수용기와 동체 사이의 공간에 도입된다. 고분자 발포체는 공간을 채우고 동체를 코팅한다. 다음에 욕조 성형품은 수용모울드가 이탈된 후 모울드수용기에서 이탈된다. 다음에 인서트가 인탈되어 감소된 두께와 영역과, 리브를 형성하는 욕조 성형품의 비마무리면의 외주를 남긴다.

Title: Method for image rotation
Inventor: OM CHOL-YONG
IPC: G06T3/00
Filed: 1992-01-13
Granted: 1995-05-25
Abstract: The method rotates an image without transformation at high speed. It includes the steps of: (i) setting a reference coordinate axis and calculating reference coordinate points of fixed angle direction; (ii) setting a scanning distance value on a reference coordinate axis to zero; (iii) getting a scanning start point and scanning an image; (iv) moving pixels line by line; (v) incrementing a coordinate value of the reference coordinate axis; (vi) going to the third step and repeatingly executing an operation when the scanning distance value doesn't reach the distance value of an image; and (vii) finishing an operation when the scanning distance value does reach the distance value of an image.
