Title: Process for preparing quinoline carboxylic acid derivatives
Inventor: PARK HAE-IL
IPC: C07D401/04
Filed: 1983-12-13
Granted: 1986-06-25
Abstract: Antibacteria active quinoline carboxylic acid derivs. (I) or its salt and hydrates are prepd. by reacting 1-vinyl substd. quinoline carboxylic acid derivs. (II) with CH2I2 and Zn-Cu compds, where R is H, C1-4 lower alkyl, lower alkoxy carbonyl; R' is H or C1-6 lower alkyl. If R' is H in (II), (II) is first esterified and then reacted as aboves. Thus, 3-chloro-4-fluoroanilino methylene malonic acid diethyl ester is prepd. by reacting 3-chloro-4-fluro-aniline with diethyl ethoxymethylene malonic acid ester at 120 - 130≰C for 2 hr and distg. the product to remove EtOH under reduced pressure.

Title: Apparatus for controlling cooking process
Inventor: WOLFRAM ANDRE
IPC: H05B3/68
Filed: 1985-01-10
Granted: 1992-10-12
Abstract: An apparatus for monitoring the cooking process in a cooking vessel placed on an electric heating element, particularly a stovetop burner, comprising signal transmitter controlled by the temperature in the cooking vessel, a signal receiver in communication with the signal transmitter by a transmitter for activating a control circuit to adjust the heat output of the heating element, and a switch for turning the apparatus on and off. During the entire cooking operation and when the heating element is set at full heating capacity, a periodical surveillance is effected to determine whether the temperature varies, remains steady or decreases. If a temperature increase is measured during a monitoring cycle, the heating element is not turned off, but if the temperature remains constant or falls, the heating element is turned off.

Then the world coordinate of the camera (2) is converted into the camera lens coordinate to convert it into an image coordinate. Then a conversion parameter is obtained by substituting the  image coordinate into the initial values of the  camera  (2).  Then  the difference between the actual and extracted positions of the image is obtained, and the image position is  determined  based  on  the difference.

Inventor: KIM YONG-SAM
IPC: C01G49/02
Filed: 1991-12-11
Granted: 1994-10-21
Abstract: synthesizing waste solution (I) of acid washing of steel and sludge (II) of Cr-plating. When mixing (I) and (II), the ratio of Cr/Fr is 12-25 wt.% and the agitated. pH is controlled to 7-8 by adding alkali solution and the heavy metal is isolated by precipitation. A small grain is made from heating, combustion and drying of deposit and has 11.0-12.5 % as reflectivity at 700 nm and 0.08-0.30 μm as distribution of particle and not discolored.

Title: Insulating layer forming method between multi-metal wired films
Inventor: LEE SANG-SANG
IPC: H01L21/28
Filed: 1991-12-27
Granted: 1994-12-23
Abstract: The method includes the steps of forming a first insulating film (15) on a first metal wiring (12) in the thickness range of 1000-1500 angstroms by a low temp. growing process, forming a second insulating film (16) on the film (15) by the high temp. growing process, forming a contact hole into the interlayered insulating films (15,16), and growing a second metal wiring (14) through the contact hole of the films (15,16). The method improves the step-coverage and the hillock effects.
