Patent KR-880001684-B1 (KR)
Title: Control method for air-fuelratio of internal combustion engine
Inventor: KUROIWA HIROSHI
IPC: F02D41/02
Filed: 1983-10-14
Granted: 1988-09-06
Abstract: In the system the supplied fuel is determined in accordance with the amount of driver operation of the accelerator or throttle valve opening.  The mixture gas is controlled by controlling the intake air amount to improve the fuel combustion efficiency. Although the fuel supplied to the engine may be controlled directly by the amount of accelerator operation that is the torque requirement of the driver to controll the intake air amount to achieve the optimum air-fuel ratio.  In the process the amount of air passing through the main air intake path may be reduced.  This is prevented by maintaining the fuel amount determined according to the throttle opening, i.e. by adding the fuel by the reduced amount.

Abstract: The method is for detecting a human body accurately by outputting a human body detection signal according to the difference in the quantity of light between the background and the human body. Infrared rays are projected by a projector (2) with a driving signal (P1) from a projector driving circuit (8).  When the human body enters a detection area, the quantity of reflected light increases and the output of a photodetector (3) also increases.  Its output is sent to a sample holding circuit (10) through an amplifier (9) and held with a timing signal (P2) from a timing signal generator (11) and the output of the circuit (10) is inputted to integration circuits (12,13).

Title: Method of inputting english character using numeral key
Inventor: BAEK SONG-CHONG
IPC: G06F3/02
Filed: 1990-08-30
Granted: 1993-03-29
Abstract: The method inputs English characters using 10  numeric  keys. The method comprises the steps: (A) checking that an input key  is '*'; (B) sending error signal for non-numeric key input  when  '*' key is not input in the step (A); (C) checking  a  number  of  the same key input and displaying a character according to the  number of the same key inputs which is determined by a  character  table; (D) counting the number of the  same  key  inputs  and  storing  a character corresponding to the number on a temperary  buffer;  (E) registering the character stored  in  the  temporary  buffer  when input key is '*' in  the  step  (A)  and  clearing  the  temporary buffer; and (F) sending error signal when no character is sored on the temperary buffer in the step (E).

Title: Method of manufacturing dispenser cathode
Inventor: CHOE JONG-SO
IPC: H01J9/04
Filed: 1990-09-07
Granted: 1992-08-31
Abstract: The method for  mfg.  the  dispenser  cathode  comprises  (a) connecting the one side of a porous cathode substrate (2)  to  the supporting board, (b) directly coating the cathode  substrate  (2) with a tungsten or a molybdenum by the plasma spray coating method or the flame spraying method to form a  reservoir  (10),  and  (c) interposing the reservoir (10) on  the  upper  side  of  a  sleeve having a heater. The cathode is useful  for  a  braun  tube  or  a projection tube, and has a long life.

Title: Syndrome circuit for bch decoder
Inventor: LEE HEUNG-SOON
IPC: H03M7/00
Filed: 1990-09-28
Granted: 1997-07-14
Abstract: A syndrome calculating circuit in a BCH decoder capable of correcting one or two errors and detecting three errors is disclosed. In the circuit, an exclusive OR gate(1) exclusively ORs input data and an output of a flip-flop(11). A flip-flop(5) stores an output of exclusive OR gate(1). An exclusive OR gate(2) exclusively ORs   outputs of a flip-flop(5) and a flip-flop(11). A flip-flop(6) stores an output of exclusive OR gate(2). An exclusive OR gate(3) exclusively ORs outputs of a flip-flop(6) and a flip-flop(11). A flip-flop(7) stores an output of exclusive OR gate(3). An exclusive OR gate(4) exclusively ORs outputs of a flip-flop(7) and a flip-flop(11). A flip-flop(8-11) sequentially stores outputs of exclusive OR gate(4).
