  • Water feed device for humidification and air conditioning apparatus incorporating the same
    Patent number: 5701950
    Abstract: There is provided a water feed device for humidification, comprising: an outflow reservoir that is disposed above a humidifier for feeding water into the humidifier by way of a permeation and that is provided with an overflow dam for maintaining a level of the water in the outflow reservoir substantially constant; an inflow reservoir that is disposed upwards of the outflow reservoir and that is provided with a flow inlet; a partition plate that is disposed between the inflow reservoir and the outflow reservoir; and a plurality of drip feed members which are provided in the partition plate for allowing the water in the inflow reservoir to drop by gravity in a form of droplets into the outflow reservoir.
    Type: Grant

  • Shading correction method, and apparatus therefor
    Patent number: 5621824
    Abstract: An image obtained by imaging an object having a solid shape, such as that of a circular column or prism, develops a distribution in brightness since the angle of each portion of the surface of the object with respect to a lighting device and image pick-up device differs depending upon the location. The distribution of brightness is substantially uniform along the longitudinal direction of the object but varies transversely of the object. One line is designated on the captured image of the object in a direction that cuts across the object, and the distribution of brightness on this line is obtained. A two-dimensional shading pattern is obtained by expanding this brightness distribution in the longitudinal direction of the object. The shading pattern represents the distribution of the brightness in the image of the surface of the object.
