IPC: B60R19/48
Filed: 1998-12-28
Abstract: PURPOSE: An air guide of a front bumper is provided to improve assembling efficiency and assembling productivity by making an air guide assembled to a front bumper without a separate tool by mounting an air guide while a clip is installed in the air guide. CONSTITUTION: An air guide(10) composed by a clip(60) fixed via a channel(12) is assembled by inserting a rib insertion hole(54) formed on the air guide to a rib protruded on a front bumper and pressurizing the air guide with a slight force. When the clip installed on the channel is inserted to the rib, sawteeth forming the clip are deformed elastically and support the rib. Thus, the air guide is fixed on the rear face of the front bumper. The air flowing in via an air inlet of the front bumper is induced to an air inflow guide face(56) of the air guide. Thereby, more air is flowed into a radiator placed in front of an engine.

Title: 소각로
Filed: 1998-12-30
Abstract: 본 발명은 투입 호퍼에 쓰레기를 투입시킨 다음 자동으로 1차 개폐기가 열리고, 쓰레기를 대기실까지 투입시킨 다음, 1차 개폐기가 닫친다.    2차 개폐기가 열리면서 쓰레기 소각로 연 소실에 투입된 다음 2차 개폐기가 닫치는 순서로 반복된다. 
     연소실에 투입된 쓰레기는 워킹 이송장치의 상승, 전진, 하강, 후진을 반복하면서 쓰레기를 이송시키므로 쓰레기 상부와 하부 교반되면서 전진, 소각이 이루어져 골고루 소각이 됨. 
     소각로 내부로 관을 설치하여 브로와 팬을 가동시켜 공기는 관을 통과하게 만들고 열 교환기를 설치하여 400℃이상 열을 얻어 워킹하부에 쓰레기 이송방향으로 공기를 공급하므로 신속한 속도로 소각이 되도록 하고 불완전 연소를 없앤다. 
     소각시 얻어지는 고온공기를 측면 Air 공기에도 사용하여 에너지 절약에 이용한다. 
     소각시에 얻어지는 고온공기를 Air Z 버너에 공급하여 연료 온도를 상승시키면서 연료와 더운공기를 동시 공급하므로 연료 입자를 분해, 연소에 도움을 주게 만든다. 
     또한, 소각로에서 발생하는 미세 유해가스를 통과시키면서 고온 1600℃열을 발생시켜 유해가스를 완전 소멸시킨다. 
     스팀 Z 버너를 이용하여 THERMO TUBE를 가열하여(1600℃) 유해가스를 THERMO TUBE 사이로 통과시킨다. 
     스팀 Z 버너 채택이유는 높은 온도에서 스팀을 발생시키면 열이 더욱 많이 발생되므로 스팀 Z 버너를 채택하여 연료절감과 고효율의 연소를 얻을 수 있다. 
     스팀 Z 버너의 스팀은 소각로 후단설비에 있는 폐열 보일러에서 얻어짐. 
     또한, 방출되는 열은 폐열 보일러와 스팀 Z 버너에 사용되며 지역 난방에도 이용할 수 있는 유익한 발명인 것이다.

Title: Single phase brushless fan motor
Inventor: PARK WANG SIK
IPC: H02K29/00
Filed: 1998-12-31
Abstract: PURPOSE: A motor is provided to reduce the rotation ripple caused by irregular air gap so the vibration or noise of the motor is prevented. CONSTITUTION: A stator yoke(40) is formed to a circular plate shape which outer radius is greater than a magnet(80) to have the uniform air gap. The outer face of the generation stator yoke equips many projections(90) for generation of cogging with certain space, which number corresponds to 1/2 of magnetic electrodes of the magnet. The projections are raised to height of the magnet circumference. The rotation ripple is reduced because of constant air gap between the stator yoke and magnet, and the uniform magnetic attraction force. It also prevents the vibration and noise caused by the rotation ripple because the friction between a rotation shaft(50) and the bearing is decreased.
