A super hydrophobic self cleaning coating composition that can be applied by conventional methods such as by spraying the composition onto a surface creating a wet and dry dirt repellent coating on the surface. The super hydrophobic self cleaning coatings are used on exterior automotive and boat surfaces, and in many other applications, to produce a self cleaning surface, reduce adherence of dirt and contaminants to a treated surface, and reduce drag in some applications providing an energy savings. The coating utilizes a blend of organic and / or inorganic polymers with hydrophobic nanoparticles of fumed silica and / or titania in a volatile solvent which evaporates at ambient temperature. The coating solves the problem of poor resistance to UV light, opaque appearance, and / or some abrasion resistance not found in previous coatings of similar nature. A preferred coating has good resistance to UV light and some resistance to abrasion. Clear, nearly transparent and translucent coatings are produced as compared to conventional coatings of comparable hydrophobicity which are typically white or opaque. The coating can be applied by a single and easy spraying method and the super hydrophobic property can be achieved by drying the film by evaporation of the solvent at ambient temperature for 5 to 10 minutes. Embodiments of the super hydrophobic self-cleaning coating composition result in a clear coating or in some cases a translucent dirt repellant film for coating on painted material, plastic, metal, glass, ceramic, fiberglass or a polymer substrate. The coating utilizes a blend of organic and / or inorganic polymers with hydrophobic nanoparticles of fumed silica and / or titania in a volatile solvent. At least one preferred coating composition comprising an effective amount of a treated fumed silica in a solvent resulting in a coated surface providing a contact angle of at least 165 degrees as compared to water having a contact angle of from 10 to 15 degrees on a noncoated surface. The composition imparts a degree of hydrophobicity to a surface so that the surface will have a tilt angle of sliding of less than 2 degrees as compared to water on a noncoated surface having a tilt angle of sliding of 90 degrees or higher. The coating composition is removed by washing with a detergent or applying pressure to the coating wiping same from the treated surface. Exposure to water in the form of rain or snow does not remove the coating composition.

An acceleration sensor includes first and second fixed electrodes on a substrate, and a movable electrode located above the first and second fixed electrodes, with respect to the substrate, and facing them. The movable electrode is elastically supported on the substrate by a first elastic supporting body and is movable. A mass, which is elastically supported on the substrate by a second elastic supporting body, moves in response to an acceleration in a direction perpendicular to the substrate. A linking portion links the movable electrode and the mass at a position spaced from an axis of movement of the movable electrode by a distance. Acceleration is measured based on changes in a first capacitance between the first fixed electrode and the movable electrode and a second capacitance between the second fixed electrode and the movable electrode. Thus, a highly impact resistant and highly reliable acceleration sensor is obtained.
