  • Heated type air flow rate sensor and its forming method
    Patent number: 6698282
    Abstract: 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.

  • Water heater
    Patent number: 6698386
    Abstract: An improved gas-fired water heater is disclosed which comprises a sealed cylindrical shell extending from the base of the water tank to the top, enclosing the burners and controls so as to shield them from flammable vapors in the immediate vicinity. The cylindrical shell forms an annular passage outside the tank (and insulation, if present), which facilitates the intake of combustion air. This annular passage is shielded from above and the side adjacent the top of the tank by a cover fitted to the tank top which extends downward from the top to form a lip which laterally shields the annular passage and directs intake combustion air upward from outside the shell to enter the annular passage. The bottom of the heater can be extended by a cylindrical skirt extension which encloses the burner of the heater in an airtight manner except for air inlets in the bottom of the extension.

  • Method and system for compensating for wheel wear on a train
    Patent number: 6701228
    Abstract: A method and system for compensating for wheel wear uses position and/or speed information from an independent positioning system to measure some distance over which the train has traveled. Wheel rotation information is also collected over the distance. The wheel rotation information and distance and/or speed information are then used to determine the size of the train wheels. The method is performed periodically to correct for changes in wheel size over time due to wear so that the wheel rotation information can be used to determine train position and speed in the event of a positioning system failure.
