IPC: C21D1/00
Filed: 2000-04-15
Abstract: PURPOSE: A cooling apparatus for heat-treatment is provided to enhance the quality by efficiently preventing the deformation of heat-treated material and to improve productivity by continuously cooling the processed material. CONSTITUTION: A cooling apparatus for heat-treatment cools the processed material(12) while continuously transferring it into a cooling tub(20) in a state of being supported between one pair of mesh belts(41). Herein, the flat processed material is heated in a heat treatment furnace(10) at a high temperature and is arranged on the mesh belt. The cooled processed material is continuously carried out of the cooling tub by hanging it on a hanging projection(52) of a carrying out device(50). Thus, the cooling apparatus prevents the generation of deformation by continuously transferring and cooling the flat processed material in a state of being supported between one pair of belts. Further, the quality and productivity are improved by carrying out the cooled processed material out of the cooling tub.

Title: Preheating method for vulcanizing mold
Inventor: KIM SANG YONG
IPC: B29C35/02
Filed: 2000-04-18
Abstract: PURPOSE: A preheating method of a vulcanization mold is provided to prevent a bladder from being damaged in a process of preheating a mold and to enhance productivity of products by shortening the preheating time of the mold. CONSTITUTION: To preheat a vulcanization mold(2) of dome type, a bladder is removed out of the mold and heat is supplied into a dome(1). The upper end of a back well(30), the connecting part of a flange(31) of the bladder connects the flange of the removed bladder simply to prevent heat from being leaked to the connecting part. When the mold is preheated to vulcanize green tires, the bladder is removed from the upper part of the back well. Then, the mold is crossed and heat is supplied into the dome. The heat is delivered to the outside and the inside of the mold to preheat the mold. Herein, the bladder is not existed inside the mold. Thereby, the supplied heat is delivered into the mold easily to shorten the preheating time of the mold. After the mold is preheated completely, the mold is opened and the flange is separated from the upper part of the back well. The bladder is connected and the green tires are vulcanized. Therefore, the bladder is not damaged in a process of preheating the mold, and the preheating time of the mold is shortened.

Title: Monitoring System And Method of Driving on Automobile
Inventor: PARK SANG WAN
IPC: B60K35/00
Filed: 2000-05-17
Abstract: A process for the preparation of substrates used in the manufacture of integrated circuits wherein spin-on low dielectric constant (low-k) polymer films are applied on semiconductor substrates. A non-etchback processing of spin-on low-k polymer films, without losing the low dielectric constant feature of the film, especially inbetween metal lines, is achieved utilizing electron beam radiation. A polymeric dielectric film (7, 8) is applied and dried onto a substrate and exposed to electron beam radiation under conditions sufficient to partially cure the dielectric layer. The exposing forms a relatively more hardened topmost portion (8) of the dielectric layer and a relatively less hardened underlying portion (7) of the dielectric layer.

Abstract: PURPOSE: A method for operating a deteriorated blast furnace in a high productivity is provided which not only stabilizes a temperature of the surface of charging materials but also enables increase of productivity and long term use of the blast furnace by forming a softening fusion space capable of activating gas flow inside the blast furnace. CONSTITUTION: The method for operating a deteriorated blast furnace in a high productivity is characterized in that a softening fusion space(2) capable of activating the gas flow inside the blast furnace is formed by a method comprising the steps of controlling a rotation chute(12) so that at least 6 or more tilting angles per notches from the center of the blast furnace are taken; supplying coke(32), large ore(34) and small ore(36) into the blast furnace by controlling an ore amount so as to form a layer thickness capable of maintaining a uniform ratio of coke to ore in a radius direction inside the blast furnace, wherein an ore amount control valve is controlled so as to control and supply the ore amount which is distributed in a flat layer form of about 0 to 25 degrees of an angle; and overlapping 3 or more of notches of tilting angles of the ore and the coke so that charging is completed.
