Abstract: Provided is a method of designing a device, comprising the steps of determining a disposing process for each component of the device, the disposing process being selectable from a melting process, a shredding process and a renovating process, and designing a connecting part for joining two of the components of the device that would be determined to be disposed by different disposing processes in the determining step so as to be easily separated from each other. Thereby, the amount of work for dismantling the device and separating the components can be substantially reduced, and the component parts can be disposed simultaneously in most part.

Abstract: A method of renovating and recycling a vehicle, comprises the steps of: (a) designing the vehicle, wherein the step of designing comprises the steps of: (a-1) determining a way of treatment, such as melting, crushing or renovating, for mach part of the vehicle; and (a-2) designing each part of the vehicle so as to form an easily disassemblable structure; (b) manufacturing the vehicle according to the design made in the step (a); (c) selling the vehicle with a limited usable period; (d) having the sold vehicle returned after the limited usable period has lapsed; (e) separating parts of the returned vehicle into those to be reused and those to be replaced with new parts; and (f) separating the to-be-replaced parts into those to be renovated or those to be processed into materials. In this ways since the way of treatment for each part of the vehicle is predetermined at the design stage, it is ensured that all the parts can be properly recycled, to thereby substantially eliminate the discarded waste.

Abstract: A roof is opened and closed by utilizing a trunk lid for opening and closing a trunk room. The trunk lid can be raised and lowered while it is held substantially horizontal. The trunk lid is provided with a roof slide unit for moving the roof in longitudinal directions.When opening the roof in a closed state, the trunk lid is raised to a position behind the roof, and the roof is moved rearwardly by the roof slide unit to be supported by the trunk lid. Then, the trunk lid is lowered down to a position to close the trunk room. This brings an end to an operation of opening the roof. A reverse procedure may be taken for closing the roof.
