  • Patent number: 7640635
    Abstract: A fixing clip for fixing an interior part of a vehicle is provided. The fixing clip is assembled in a body with the interior part via a headlining by a screw and is fixed to a mounting bracket provided in a vehicle body. The fixing clip includes a bottom part provided with a screw hole through which the screw is fastened and being in close contact with an upper surface of the interior part, a pair of body parts extending and being bent upwardly from both ends of the bottom part to face each other, and a pair of coupling parts extending and being bent outwardly and downwardly from upper ends of the body parts and being inserted into clip insertion holes provided on the mounting bracket. Accordingly, the clip can firmly and easily mount/separate an interior part on/from the vehicle body with its deformation, damage, or unexpected seceding due to an external force prevented.

  • Publication number: 20080291000
    Abstract: The present invention relates to a collision avoidance system based on the detection of obstacles in the blind spots of a vehicle. The collision avoidance system includes turn signal lamp detection means for detecting whether a turn signal lamp of the vehicle is turned on. CCD camera means captures an image for a road environment, and outputs the captured image as road environment data, thus determining whether a current road environment indicates a winding road. Steering angle detection means detects a steering angle of the vehicle and outputs a resulting signal as a steering angle signal. Infrared sensor means transmits or receives infrared light to or from an obstacle present in the blind spot of the vehicle according to the steering angle signal, and outputs an obstacle detection signal. Warning means is configured to provide a warning of possibility of a collision between the obstacle and the vehicle to a driver.

  • Patent number: 6828254
    Abstract: A plasma enhanced chemical vapor deposition apparatus and a method of forming a nitride layer using the same, wherein the plasma enhanced CVD apparatus includes a process chamber including an upper chamber with a dome shape, a lower chamber, and an insulator therebetween, a gas distributing ring, a susceptor for supporting a wafer and heating the process chamber, a plasma compensation ring surrounding the susceptor, a vacuum pump and an electric power source connected to the process chamber. The gas distributing ring has a plurality of upwardly inclined nozzles, allowing upward distribution of reactive gases. The method of forming a nitride layer includes forming a protective film on inner walls of a process chamber, the protective film having at least two layers of differeing dielectric constant, and sequentially supplying reactive gases to the process chamber. A nitride layer formed thereby has low hydrogen content, good density and oxidation resistance.

  • Publication number: 20030160488
    Abstract: The present invention relates to a turning table of a seat for a vehicle which includes a lower plate installed in a floor of a vehicle, a first slider installed on an upper surface of the lower plate, a turning plate rotatably supported by the first slider, a second slider installed on an upper surface of the turning plate, and an upper plate which is supported by the second slider and integrally fixed to the lower plate. The upper protrusion of the lower plate which supports the corner portions of the lower plate and the turning plate and the lower protrusion of the turning plate are engaged each other. The lower plate and the upper plate are stable fixed. The first and second sliders integrally form the connection portions between a plurality of the ball portions. In the present invention, in a state that the seat is stopped, it is possible to easily prevent a movement of the seat based on an engagement between the upper protrusion of the lower plate and the lower protrusion of the rotation plate.
