Abstract: PURPOSE: A wheelchair is provided to easily pass through a narrow path by controlling a width between wheels by rotating wheels together with a cross shaft-connecting which is connected to a wheel. CONSTITUTION: A wheelchair comprises a sheet main body(800), wheels(400a,400b) sheet frames(200a,200b), frame reinforcing supports(300a,300b,300c,300d), and a cross shaft connected to the wheels. The seat main body is arranged in a center part of a wheel chair. The wheels are in one side and the other side of the seat main body. Connections units with the seat main body of the sheet frame are inserted into the one side and the other side of the seat main body. The frame reinforcing supports horizontally penetrates the sheet frame. The cross shaft connected to the wheel is connected to a shaft of the wheel, and in which the frame reinforcing support is inserted. The wheel rotates around the frame reinforcing support as an shaft together with the cross shaft.

Abstract: PURPOSE: A polymer film and a coating method thereof are provided to reduce adhesive force, frictional force, and abrasion generated from the friction between the polymer film and a differing material. CONSTITUTION: A coating method of a polymer film comprises the following steps: forming the polymer film by coating a polymer solution including a polymer material and a solvent on a substrate(S100a); and heating the polymer film to a temperature higher than the glass transition temperature of the polymer material, and lowering than the boiling point of the solvent(S200a).
Abstract translation: 目的：提供聚合物膜及其涂布方法，以减少由聚合物膜和不同材料之间的摩擦产生的粘合力，摩擦力和磨损。 构成：聚合物膜的涂布方法包括以下步骤：通过在基材上涂覆包含聚合物材料和溶剂的聚合物溶液来形成聚合物膜（S100a）; 并将聚合物膜加热到高于聚合物材料的玻璃化转变温度的温度，并且比溶剂的沸点低（S200a）。
