摘要： PURPOSE: To make a subsequent polishing process simple by a method in which in advance of the application of a repairing paint, the surface of a repair part is wetted with one or more kinds of organic solvents selected from specified ester-type and ether-type organic solvents. CONSTITUTION: In a repairing method in which the repair part of a crosslinked clear paint film is sanded and coated with a repairing paint, in advance of the application of the repairing paint, the surface of the repair part is wetted with one or more kinds of organic solvents selected from ester type organic solvents with a boiling point of 200-250 deg.C and ether type organic solvents with a boiling point of 200 250 deg.C. In this way, the wettability of the repairing paint improves so that the applied paint can spread thinly. After the application, the paint film is crosslinked in conditions according to the composition of the paint. After curing, the difference in the evenness from an unrepaired part is eliminated as necessity requires, or the repaired part is polished for glossing.

摘要： PROBLEM TO BE SOLVED: To improve interlaminar adhesion between a first clear paint film and a second clear paint film by a method wherein a colored base coating material and a first clear coating material are applied to a shell part of a car body, preheated at a specific temperature, and thereafter a second clear coating material is applied, and heated to cure three layers of paint films simultaneously. SOLUTION: A colored base coating material and a first clear coating material are applied to a shell part of a car body, and both paint films are preheated at 70-100 deg.C. After applying a second clear coating material thereto, these three paint films are simultaneously cured by heating. Herein, both paint films composed of the colored base coating material and the first clear coating material are not crosslinked and cured by this preheating, gel fraction is about utmost 5wt.%, and further a solid content of the first clear coating material is preferably about 80wt.% or higher. Thereby, thick film (for example, about 30μm or over in cured paint film) application of the second clear coating material can be executed, and further interlayer adhesion between the first clear paint film and the second clear paint film is improved.

摘要： PROBLEM TO BE SOLVED: To provide a lane recognition device which does not interrupt a process to measure information of a track only by change of a result of measurement of the information of the track due to displacement of a vehicle along a vertical direction.
SOLUTION: The lane recognition device obtains a difference of a lane width at a time interval defined beforehand based on an image picked up with a camera, and further obtains a difference of a pitch angle of an own-vehicle at the time interval based on the height measured by a vehicle height front part sensor and vehicle height rear part sensor. The lane recognition device estimates the amount of variation of the lane width which is measured when the camera displaces only for the difference of the pitch angle based on the obtained difference of the pitch angle, and adjusts the tolerance to the lane width defined beforehand only for the estimated amount of variation.
