Date Apr. 16, 1992.A device for the qualitative and/or quantitative determination of the composition of a sample to be analyzed. The device includes at least one hollow body which is coated on the inside with an optically reflecting material or is composed completely of an optically reflecting material, and which is provided with at least one aperture. At least one radiation detector is provided proximate to the hollow body in the interior of the hollow body or in the vicinity of the hollow body. At least one ATR (Attenuated Total Reflection) element covers the at least one aperture of the hollow body, and the sample which is to be analyzed is disposed at the side of the ATR element turned away from the hollow body. At least one primary radiation source provides radiation which is received by the ATR element without directly entering the hollow body.

Title: Defrosting method & equipment of refrigerators
Inventor: JO KWANG-YEUN
IPC: F25D21/00
Filed: 1993-02-10
Granted: 1997-04-11
Abstract: A defroster of refrigerator having ventilator(31), first and second heater(50,51), temperature sensor(32,35) and anti-backward flow prevent plate(34) is disclosed.The ventilator(31) is installed in the entrance of cool air moving to refrigerating chamber(30).  The frist and second heater (50,51) is installed in cool air passage(33) by means of bracket, and temperature sensor(32) senses the temperature of cool air in refrigerating chamber. And the temperature sensor(35) senses the temperature of cool air when the cool air vent out from refrigerating chamber, and the anti-backward flow prevent plate(34) prevents backward flow of the cool air.Thereby, it is possible to get effective defroster and defrosting method by makes the cool air in refrigerating chamber(30) and hot air in heater(50,51) to flow alternately to freezer(40). And when the defroster works, foods in refrigerating chamber(30) and freezing chamber(20) are not degenerated. And decrease of power consumption is expected.

Title: Centrifugal spray cooling nozzle
Inventor: LEE SANG-HWA
IPC: B05B1/00
Filed: 1993-05-08
Granted: 1996-04-25
Abstract: The nozzle lowers large temperature difference and cools high temperature of waste water directly. The nozzle consists of an evaporation room(1) having 2 to 6 inclined holes(A) formed on the side wall, and a nozzle(2) connected with the central part of the nozzle and a fixing metal(4) having same outer diameter of a fast flowing tank(B). The inclined holes have same direction of the water flow of the central part(3). The diameter d2is there times of the diameter d. The L2is 1.5 times of d2. The cone angle is between 30 degree to 40 degree. The height of the evaporation room(1) L4 equals to cos( M/2)-h.
