Abstract:
A method of measuring a friction coefficient of a surface of a specimen includes: obtaining surface information of the specimen by using an atomic force microscope (AFM); calculating data of a friction coefficient of the surface of the specimen by using the surface information of the specimen; and mapping the data of the friction coefficient of the specimen to an image. The method of measuring a friction coefficient of a surface of a specimen may prevent a probe part of an atomic force microscope from being worn out and secure high reliability of the friction coefficient value by correcting the atomic force microscope using a specimen to be actually measured and measuring a fiction coefficient at the same time.
Abstract:
A door checker for a vehicle includes a hinge rotatably connecting a door to a vehicle body and having a shaft, a slider penetratingly inserted into the shaft and linearly moving with rotational force of the shaft, and a checking unit linearly reciprocating in a radial direction of the shaft by the slider. By implementing a manipulation feeling in opening and closing a door by increasing a section for checking the door by converting a rotational movement of the door into a linear movement based on a screw principle, operability can be improved to enhance marketability, and durability can be enhanced by increasing the section for implementing operating force for opening and closing a door.
