    • High-grade three-dimensional images can be observed without a bright image of an exit end of an image projector superposed on the three-dimensional images. In a method of reproducing three-dimensional images by a three-dimensional image-reproducing device provided with an image projector and a directional reflective screen for collecting light from the image projector toward a specific position in a horizontal direction and for diffusing the light in a vertical direction, the directional reflective screen and the image projector are positioned with respect to the observer observing the three-dimensional images such that the observer is outside a region traversed by a portion of light rays which enter the directional reflective screen from the image projector, then are reflected by a surface of the directional reflective screen incapable of contributing to the reproduction of the three-dimensional images, and form a mirror image or a conjugate image of the image projector.

    • In an automatic faucet having a hand sensor S to start and stop discharging water automatically, only hands can be detected accurately without detecting a washbowl (chinaware) and water stream erroneously. The sensor S comprises a light emitter and a light receiver. The directional axis d of a detection region (in which the light emitting region of the light emitter and the light receiving region of the light receiver are overlapped with each other) intersects the discharged water stream, and further the intersection angle between both is adjusted less than 70 degrees, irrespective of the flow rate of the discharged water. The reflected light levels detected by the light receiver are sampled periodically to calculate an average value and a variance value on the basis of at least eight most updated sampled data. Water discharge is started and stopped on the basis of the calculated average value and the variance value.
