Abstract: Provided is a method of automatically combining a farm vehicle with a work machine including confirming a current position of the work machine, moving a farm vehicle into a range having a predetermined radius around the current position, and controlling the farm vehicle, on the basis of a current position and direction of a first coupling unit included in the work machine, so that the first coupling unit and a second coupling unit included in the farm vehicle are coupled to each other.

Abstract: The present disclosure relates to an apparatus for automatically locking a container, which includes: a cylindrical housing: a top plate installed on the top of the housing; a bottom plate installed under the housing; an elevation unit installed to move up and down in the housing; a locker installed to rotate left and right to lock and unlock a container; a guide guiding up-down movement and rotation movement of the locker; a first elastic supporting member elastically supporting upward the elevation unit; and a second elastic supporting member elastically supporting upward the locker. Accordingly, the present disclosure provides an effect that a container is automatically locked or unlocked by its own weight when it is loaded or unloaded, so it is possible to safely transport heavy containers always in a locked state and it is possible to prevent malfunction or poor function of the locker.

Abstract: Provided is an in-vehicle operation button installation structure, including: a surface material in which a button operation unit is formed on a portion; and an operation button assembly attached to a back surface of the surface material and including a button corresponding to the button operation unit.

Abstract: A computational method is provided for predicting roadway failure due to degradation of the roadway over time as a function of the input loads, the roadway geometry, the material properties of the constitutents in the asphaltic pavement, the shape, distribution, orientation and volume fractions of the constituents, and environmental conditions. The unique and new feature of the method is that it employs several physically based predictive methodologies simultaneously.

Abstract: A swing structure for a kick scooter includes a center tube, an axle pipe, a first bushing pad, a second bushing pad and a cap. The center tube comprises a pair of ring plates spaced from each other and a protuberance. The axle pipe is provided with a bracket. The first bushing pad is disposed on the bracket and located between the two ring plates of the center tube. The first bushing pad has a restricting slot for insertion of the protuberance of the center tube. The second bushing pad is coupled to the first bushing pad. The cap covers the second bushing pad and is secured to the bracket by means of fasteners.
