Patent KR-0159936-B1 (KR)
Title: The television receiver equipped with an auxiliary input terminal
Inventor: SENDELWECK GENE KARL
IPC: H04N9/87
Filed: 1990-04-17
Granted: 1999-01-15
Abstract: An auxiliary video input terminal (S-terminal, 10) 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 (64) is subjected to pre-distortion (de-peaking(80)) to correct for sideband amplitude distortion in the chrominance peaking filter (58) of the receiver thereby preventing color distortion in displayed images. The luminance signal (62) is subjected to additional peaking (70) 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: 2.1 Comparators, on the input signal of which high-frequency oscillations are superposed, tend towards overshoots in the vicinity of the switching threshold, which can be prevented by a capacitor of relatively large capacitance at the input of the comparator. Because of the high capacitance, such comparators cannot be produced as ICs. 2.2 To achieve a comparison circuit which is both overshoot-free and can be produced as an IC, the input signal (U) is supplied to one input of a transductance amplifier (V), the output of which is connected to an integrator (I) and at the other input of which a first reference quantity (Ref 1) is present. The output of the integrator (I) is connected to one input of a comparator (K1), at the other input of which a second reference quantity (Ref 2) is present. At the output of the comparator (K1), an overshoot-free signal (D) can be picked up which can be used, for example, for controlling a switch. 2.3 Comparison circuits with overshoot-free output signal which can be produced as ICs. <IMAGE>

The process comprises introducing particles of an oxide ore entrained in a gas through a port into a treatment chamber. Inside the treatment chamber teh stream of entrained particles combines with a stream of high temperature reducing gas in such a way that the particles are heated rapidly and enter into flow patterns whereby contact with other particles and the internal surface of the treatment chamber is minimized. The stream of entrained particles and the stream of high temperature reducing gas are substantially co-current. A treatment chamber elongated in the direction of co-current flow is described in the specification. The hot off-gases may be derived from a molten bath reactor and comprise a high concentration of carbon monoxide and hydrogen.

Abstract: The method for forming insulating layer for element separation comprises the steps of forming a trench over a silicon substrate and depositing a thermal oxide layer, a nitride layer and a BPSG layer over the whole surface; making the BPSG layer flat, ion-implanting a silicon germanium atom and forming an amorphous layer over the surface of the BPSG; removing the amorphous layer and the BPSG layer and forming a TEOS layer over the upper portion of the whole structure; and etching back the TEOS layer until the upper portion of the nitride layer is exposed, filling the trench with the thermal oxide layer, nitride layer, BPSG layer, amorphous layer and TEOS layer and forming an insulating layer for element separation.

Title: Braille recording and reproducting method & appalatus using cassette tape
Inventor: SHIN HYUN-O
IPC: G11B20/00
Filed: 1992-11-25
Granted: 1995-05-01
Abstract: The braille is recorded on a cassette tape and the recorded braille is reproduced on an electronic braille plate by using the apparatus and the method. Same natural frequency is endowed to the first and the fourth point, the second and the fifth point and the third and the sixth point of a six point type braille and the points are categorized in to two frames, the first to the third and the fourth to the sixth. The frequency corresponding to the first to the third points are reconded on ane track of a tape by frame units and the frequency corresponding to the fourth to the sixth are recorded on the other track by frame units. An additional frame pulse is recorded to distinguish frames.

Title: Method of producing artificial leather sheet
Inventor: LEE HO-KYUNG
IPC: D06N3/14
Filed: 1993-04-15
Granted: 1996-03-06
Abstract: The artificial leather-like sheet is produced by (a) composite spinning a nylon-6 as an island component and a copolymeric polyester as a sea component, (b) opening and carding the composite fiber, laminating it with a web, and needle punching the laminated fiber to make a three dimensional interlaced nonwoven fabric, (c) padding the nonwoven fabric with 5˜10% concn. of a water dispersible polyurethane emulsion, drying it at 100˜120deg. C, and heat-treating it at 150˜170deg. C for 1˜5min, (d) treating the fabric with 5% concn. of a sodium hydroxide solution at 95deg. C for 20˜50min, and (e) dipping the fabric into a dimethyl formamide solution of the polyurethane elastomer. The leather-like sheet has a good softness and bending property.
