Abstract: The present invention relates to a self-propelled working robot, including a first distance sensor 4a and a second distance sensor 4b (4c) for measuring the distance to an obstacle W in front of the robot. The robot includes first determination means for comparing a first measured distance Dc to the obstacle obtained by the first distance sensor 4a with a predetermined first threshold value to determine the proximity to the obstacle W, second determination means for comparing a second measured distance Dr (DL) to the obstacle W obtained by the second distance sensor 4b (4c) with a predetermined second threshold value to determine the proximity to the obstacle, and changing means for changing the first or second threshold value based on information regarding an inclination angle of the obstacle W obtained from the first and second measured distances.

Abstract: The present invention relates to light transmitting panels mainly applied to lighting windows in openings of general buildings and lighting quantity or range adjusting methods for interiors of general buildings using any of the light transmitting panel's. One of the light transmitting panels consists of two transmitting plates and plural refractive columns located in parallel to each other between the two plates, and another of the light transmitting panels consists of base faces with reflecting zones parallel to each other formed on them. Furthermore, optional sunlight patterns S1, S2 and S3 incident from the sun located differently in altitude or azimuth with respective incident angles of .alpha.,.beta. and .gamma. in reference to altitude or azimuth satisfying the relation of .alpha.<.beta.<.gamma.

Abstract: The present invention provides fundamental materials excellent in general purpose used for buildings, etc. as windows and interior and exterior walls of general buildings, houses, cars, etc., concretely, various laminates with the flip-flop effect (the effect of delicately changing in color, depending on the angles of view) and a decorative effect due to a colored mirror face, which are composed at least of a light-transmitting or light-intercepting base and a brightening pigment prepared by covering mica grains on the surfaces with titanium oxides including low-valent titanium oxides.
