    摘要: A cylinder pressure sensor is adapted to detect a cylinder pressure by detecting a change in the amount of light being transmitted through an optical fiber in an axial direction. Two support portions support the optical fiber at two points along the length thereof. A diaphragm in contact with the optical fiber causes bending of the optical fiber in dependence upon a change in the cylinder pressure. The position at which a force is applied against the optical fiber by the diaphragm is deviated from a center position between the two support portions. The resulting cylinder pressure sensor is capable of accurately measuring cylinder pressure and knocking over a long period of time with a low cost and reduced initial variations.

    摘要: In a structure in which peripheral part of a diaphragm section of an electrical insulating film is covered with a protective film made of an organic material, the resistor wire on the diaphragm section crosses the peripheral part of the diaphragm section. At a place where a narrow wire of a resistance temperature detector and the like crosses the peripheral part of the diaphragm section, the protective film is thinner than the other part, and the dust impact resistance is reduced. At a place where a heating resistor wire connected to a heating resistor body or resistance temperature detector wires connected to resistance temperature detector bodies cross a periphery of the diaphragm section, a film component protruding from an electrical insulating film is arranged side by side with the heating resistor wire or the resistance temperature detector wires.

    摘要: The object of this invention is to provide a heated type air flow rate sensor for measuring an air flow rate using heat generating resistive element or resistor formed within a diaphragm of which periphery is fixed, in which diaphragm destruction due to the collusion of dust is adapted to be prevented. Tapers of two or more stages are formed at a diaphragm fixing flange, and the angle of the most inside taper is made smaller than the angle of the taper which is outside with respect to the most inside taper. When dust collides with the diaphragm and the kinetic energy is transformed into distortion energy, the diaphragm destruction is avoided by making small the slope of the load-displacement curve at the neighborhood of the diaphragm flange to make the generated load small.
