Abstract: PROBLEM TO BE SOLVED: To supply water in response to a time when water is required for a life, fire prevention or due to emergency such as a man-made disaster and a natural disaster, by juxtaposing water storage tanks in both side spaces of an abutment, and storing a fixed quantity of water by natural water supply/discharge. SOLUTION: Water storage tanks 5 are juxtaposed in both side spaces of an abutment 1. Water is introduced by a conduit 11 from a mountain stream higher than the water storage tanks 5 to be supplied to the water storage tanks 5 from a water supply port 8 of an upper part of the water storage tanks 5 in the principal of a siphon. Rain and snow fallen on a bridge floor upper surface are gathered in a catch basin so that water is supplied from the upper part of the water storage tanks 5. The water overflows when a water level in the water storage tanks 5 rises and reaches a drain port 15 to naturally flow to a sewage work port. When requiring the water, a water intake port 7 or a manhole 10 is opened so that the water is taken and supplied. Thus, motive power is obviated, the water can be used as water for a water source reservoir of service water/sewage water and fire prevention, the water can be supplied when emergency is caused, high water pressure can be used in a high place, for example, the water can be sprinkled for a fire such as a forest fire, and can be used for preventing freezing and melting snow in a mountainous region and a cold district.

Abstract: PURPOSE:To produce in a low cost a push button for switch with its function indicated, after forming a coat containing a colored-pigment on the surface of a base for the push button, and irradiating letters or figures indicating the intended functions by means of a laser beam so as to remove the coat. CONSTITUTION:On the surface of a push button base made of a plastic such as ABS resin, polycarbonate, acryl resin, etc., a coat 2 containing a colored pigment is formed, then, a laser beam with 0.8-12mum in wavelength and 0.1-120W in power is radiated on the coat in such a manner that the irradiated part corresponds to the letter or figure representing the intended function of the switch, and the coat on the irradiated part 3 is removed, thereby push button for switch having the switch function indicated can be produced in a low cost. Solid-state laser is more appropriate as a laser beam for drawing letters and figures precisely. Because the irradiation technique only consists of focusing the laser beam on the part to be decomposed on the coat, it is feasible whether irradiated from the base side or the coat side but it is desirable to be irradiated from the coat side. This procedure allows to produce a push button outstanding in abrasion resistance and having its function displayed with delicate and exquisite letters and figures.
