Patent KR-0159937-B1 (KR)
Title: Television receiver equipped with an auxiliary input terminal
Inventor: SENDELWECK GENE KARL
IPC: H04N9/64
Filed: 1990-04-17
Granted: 1999-01-15
Abstract: An auxiliary video input terminal (S-terminal) couples luminance amd chrominance input signals to respective inputs of peaking circuits (52, 58) in the display processor (40) of a receiver. The chrominance input signal is subjected to pre-distortion (de-peaking) (80) to correct for sideband amplitude distortion in the chrominance peaking filter of the receiver thereby preventing color distortion in displayed images. The luminance signal is subjected to additional peaking (52) at a frequency greater than the characteristic peaking frequency of the luminance peaking filter thereby enhancing the sharpness of wideband luminance input signals displayed by the receiver. <IMAGE>

Abstract: Disclosed is an apparatus for a digital piano.  The apparatus comprises a barcode reading means, a data converter, a system controller and a synthesizer.  The barcode reading means scans a barcode of music to read a barcode signal.  The data converter converts the barcode signal into a digital signal, and provides the digital signal to a RAM.  The system controller provides a control signal to the data converter, and controls reading the music data from the RAM and storing to the RAM.  The synthesizer converts the music data from the RAM into an analog signal, and synthesizes the analog signals for an output.  Thereby, the apparatus has a simple structure, and is convenient to use.

Title: N-substituted benzimidazole derivatives with amide groups
Inventor: PARK YOUNG-JOON
IPC: C07D401/04
Filed: 1993-10-08
Granted: 1997-02-06
Abstract: A benzimidazole derivative of structural formula(I) is prepared by the following two methods. (A) The sulfur atom is oxidized by starting material of structural formula(II) to produce a compound of structural formula(III) in  oxidization, substitution or condensation reaction. (B) A compound of structural formula(II) is substituted by hydroxyalkyl, alkoxycarbonyl or like to produce a compound of structural formula(IV), and then oxidized. In the above formula, R1 is low-level alkyl, cycloalkyl, hydroxyalkyl, alkoxyalkyl or like as substituents  introduced by substitution or condensation reaction. R2 is alkyl, alkoxy group including hydrogen atom, methyl group. R3, R4, R5 are hydrogen atom where C1~C3 is alkoxy group and n is 0 or 1.

Title: Refractories by fusion casting
Inventor: KIM YEUN-HO
IPC: C04B35/107
Filed: 1993-11-04
Granted: 1996-08-22
Abstract: This casting method is an application of lost wax casting used in metal casting. This process consists of making a wax model, casting it with a refractory as burying material of liquid phase to form a mold, heating at 800deg.C during 3hrs, holding at 350deg.C for 30min. and slow cooling until the wax melts and runs out of the mold, and then pouring molten glass into the vacant mold. The buried material in lost wax casting is plaster, on the other hand in this casting, alumina refractory with high melting point over 1600deg.C and good wear resistance is used for casting of molten glass. This burying material comprises alumina refractory powder 100g, mulite 10g, and water 400g. The alumina refractory is selected from sintered alumina refractory, sintered alumina firing insulator, and fused cast refractories.

Abstract: 에코 소거 장치(1)는 에코(r(i))가 발생하기 쉬운 데이터(x(i)) 및 에코의 영향을 받은 데이터(y(i) + r(i))를 수신한다. 에코 합성기(50)는 지연 소자(70 1 , ···, 70 N )에 의해 지연되고, 가중 계수 c k (여기서 k = 1, ···, N)에 의해 가중된 일련의 데이터를 근거로 에코(r(i))의 복제본(r'(i))을 형성한다. 산술 소자(85)는 계수(c k )를 결정한다: 
     c k (i+1) = c k (i)+d·c k (i)·sign[(x(i-k)·e(i)], 여기서 d < 1
