The present invention relates to a technology of solving an issue where screens are contaminated with pollution caused by fingerprints, cosmetics, etc. on covers or windows of mobile devices such as smartphones, tablets, etc. and other user contact devices, thereby maintaining the excellent surface hardness properties of existing covers or windows and preventing deterioration of surface properties (antifouling properties) even when used long-term. The method for forming a surface having super water-repellent and super oil-repellent properties comprises the steps of: etching a surface of a target on which a surface with super water-repellent and super oil-repellent properties will be formed, to thereby form a surface structure in which convex parts () and concave parts () are continuously formed; and performing a conformal coating for coating a fluorine-based material on the surface structure which is etched on the surface of the target, wherein all configuration walls of the convex parts and all configuration walls of the concave parts are coated at a uniform thickness.

A method for manufacturing a mold includes (a) anodizing an aluminum substrate at a voltage of 60 V to 120 V in an electrolytic solution in which two or more species of acid are mixed, and forming an oxide film having a plurality of minute holes on a surface of the aluminum substrate; and (b) removing at least a portion of the oxide film. The electrolytic solution used in (a) satisfies the relation (D1)/2<D2, where D1 is the current density when the aluminum substrate is anodized under the same conditions as in (a) in an electrolytic solution of only the acid (A) having the highest acid dissociation constant (Ka) of the two or more species of acid, and D2 is the current density when the aluminum substrate is anodized under the same conditions (a) in the same electrolytic solution as that of (a).

The invention relates to a motor vehicle assembly for protecting a sensor/transmitter of a driving assistance system comprising a protection device that partially surrounds the sensor/transmitter where the protection device includes a first subassembly (B) with a detection/transmission element positioned facing a sensor/transmitter's surface via which a signal passes, and a second subassembly (C) that includes a motor configured to rotatably drive the first subassembly (B) about a line of transmission/reception of the sensor/transmitter. According to the invention, the protection assembly includes at least one heating element controlled by a control unit that heats an accessory attached to the motor vehicle's body in the detection/transmission element's vicinity, the heating element being outside the protection device and in the vicinity of the first subassembly (B).
