Filed: 1998-04-29
Abstract: 본 발명은 다결정 실리콘을 이용한 차량용 반도체 센서의 제조방법에 관한 것으로, 상세하게는 다결정실리콘을 이용하여 반도체 센서를 제조함으로서 센서의 동작온도의 범위를 확대시켜 차량의 엔진과 같은 고온 환경에서도 양호하게 적용이 가능한 다결정 실리콘을 이용한 차량용 반도체 센서의 제조방법에 관한 것이다. 
     본 발명에 따른 다결정 실리콘을 이용한 차량용 반도체 센서의 제조방법에 의하여, 다결정실리콘을 이용하여 압력센서 혹은 가속도센서를 제조함으로서 단결정실리콘을 이용할 때 보다 저항온도계수가 낮아서 온도의존성이 낮으며, 그리고 더 넓은 동작온도범위에서 직선적인 저항의 변화를 얻을 수 있어 자동차 엔진등의 고온환경에서도 적용이 가능하다.

The cooled cold air rises along with a vertical part of the intake duct(11), comes to an exhaust duct(13) through a vent hole(19), flows downward along with the exhaust duct and flows in the cold storage chamber through plural exhaust holes(25). The cold air circulating the freezing chamber is flowed in both horizontal parts of the intake duct(12) for the freezing chamber through an intake hole(27). The cold air reaching the evaporator rises upward along with the vertical part of the intake duct after cooled by the evaporator. Then, the cold air is flowed in the freezing chamber through the vent hole from the exhaust duct and completes one cycle of circulation to the freezing chamber.

Title: Stator assembly structure of linear motor
Inventor: KU BON CHEOL
IPC: H02K41/02
Filed: 1998-12-31
Abstract: PURPOSE: A stator assembly structure of a linear motor is provided to laminate core(21) of stator assembly which includes laminate(20) laminated radially to make cylinder-type multiple core(21) with ease, and to organize the laminated core(21) with density. CONSTITUTION: A stator assembly structure of a linear motor includes a looped coil bobbin(10) in which a coil(12) is wound, a laminate(20) organized as core(21) is laminated radially on the coil bobbin(10), and a wedge(40) to densify the organization of the laminated core.
