摘要： PROBLEM TO BE SOLVED: To facilitate the cleaning of dirt on a metal surface due to abrasion powder by coating photocatalyst titanium oxide on the outer surface of components for a vehicle such as a disc brake and a wheel. SOLUTION: A coating layer 12 of photocatalyst titanium oxide is formed on the outer surfaces of a caliper 1 and a support 2 of a disc brake. If the metal surface of the disc brake becomes dirty due to dispersion of abrasion powder of a brake pad, a ultraviolet ray of the sunlight is irradiated on the metal surface through a through hole 10 of an aluminum wheel 11, the coated photocatalyst titanium oxide brings about catalyst, and the dirt due to the abrasion powder of the brake pad can be resolved in a boundary surface toward the photocatalyst titanium oxide coating layer 12. This constitution can easily remove the dirt by a daily simple cleaning without using any special detergent.

摘要： PROBLEM TO BE SOLVED: To eliminate flow passage switching means, simplify the whole of a system, and reduce costs by filling a magnetic fluid between a pair of magnetic poles, applying a magnetic field to the magnetic fluid through the magnetic poles, and moving at least one of the magnetic poles so as to feed the magnetic fluid which is attracted between the magnetic poles. SOLUTION: When current-carrying is made to a second magnetic pole (an electromagnet) 8, a magnetic circuit is formed between first and second magnetic poles 2, 8 by magnetic force to be generated, and magnetic particle is attracted. When the first magnetic pole (a rotary cylindrical body) 2 is rotated by a motor 4 in this condition, a magnetic fluid is moved in the rotational direction of the cylindrical body 2. After that, the magnetic fluid is released from a magnetic field, and comes freely. Namely, dispersion soot is also transported from the inlet chamber side to the output chamber side together with the magnetic particle by rotation of the cylindrical body 2. When the density of the magnetic particle is increased, the dispersion soot is dragged by the cylindrical body 2 and the magnetic particle, and is also fed to the output chamber 7 side, and thereby, pressure in the output chamber 7 is increased so as to operate an actuator communicated with an output port 11.
