| In a conventional air flow meter, in the case of foreign matter having a large particle diameter, the inertia thereof is used as a measure to prevent contact with a detection element, but for foreign matter having a particle diameter of 10 μm or less and an extremely small mass, the inertia thereof inside a bypass structure has almost no effect, and the foreign matter can adhere to the detection element. AC dust or the like defined by the SAE standard J726C in the U.S. being mainly cited an example of the abovementioned foreign matter having a particle diameter of 10 μm or less and an extremely small mass, it is known that sand (dust) manufactured by refining Arizona desert sand is readily charged, and once dust having an extremely small particle diameter that has become electrostatically charged adheres to a detection element, the problem arises that the dust is difficult to eliminate, due to the Coulomb force thereof. This problem can be solved by a thermal-type flow rate sensor characterized by being provided with a semiconductor element for sensing a flow rate, an insulating layer and a resistive wiring layer being formed on a semiconductor substrate such as a silicon semiconductor substrate in the semiconductor element, a region (diaphragm) in which a portion of the substrate is removed to forma thin film being present, at least one heating resistor (heater) being provided in the diaphragm region, temperature measuring resistors for detecting a temperature difference being arranged upstream and downstream of the heating resistor, and an electroconductive film being formed on the semiconductor element so that the electrical potential on the surface side exposed to an air flow in a peripheral region of a wiring resistance in the diaphragm is a certain arbitrary potential. | ||||||

| An apparatus and method for adaptive materials arranged in a variety of orientations and with a wide range of attachment configurations to induce structural vibrations at extremely high frequencies. These mechanical vibrations cause fouling agents to become detached and accordingly “clean” an otherwise dirty element or wire of a hot-wire anemometer, planar or curvilinear sensor surface, or display surfaces. They also can be made to vibrate at such frequencies with such intensities that local droplets of water are either shaken off or instantaneously cavitate, thereby allowing the elements to be used in all weather conditions. | ||||||
