摘要： An electronic device includes a chamber having a chamber wall surface defining a liquid-tight sealed space; an electronic unit housed in a liquid-tight case, the case being disposed in the chamber to define an intermediate space between the case and the chamber wall surface; a biasing unit in the chamber that biases the case toward a predetermined neutral position in the intermediate space; a liquid disposed in the intermediate space; and an iris system formed in the chamber such that when the case moves toward a portion of the chamber wall surface, the iris system cooperates with the case to define a flow path through which the liquid in a portion of the intermediate space between the case and the portion of the chamber wall surface flows to another portion of the intermediate space, a cross-sectional area of the flow path decreasing as the case moves closer to the portion of the chamber wall surface.

摘要： A color perception test has a color matching processor that executes a color matching processing on a color monitor, and an image display controller that displays two or more images for color perception test in order on the color monitor on which the color matching processing was done. When displaying each image for color perception test, a color perception test is done in a state that one of its hue, brightness, saturation and display time is changed and the other elements are fixed. Since the color perception tester has the color matching processor, colors of the image are not changed with passage of time different from color printed one, and correct test can be done thereby. If the test is periodically done on some examinee, a degree of decreasing color perception function by aging can be exactly known.
