摘要： PROBLEM TO BE SOLVED: To effectively remove snow by means of a small-scaled equipment. SOLUTION: A third membrane 4c is provided between membranes 4a and 4b forming an air tent 4, and an air chamber 14a is formed of the membrane 4c together with the membrane 4a. A plurality of air inlets 20a are provided to specific positions in the periphery of the air chamber 14a, a ventilating pipe 22a is inserted from the air inlets 20a to the inside of the air chamber 14a, and the front end thereof is fixed to the inside of the air chamber 14a in a state to enter the air chamber 14a by specific distance. A plurality of exhaust ports 20b are formed in specific positions in the periphery of the air chamber 14a. A warm current of air from a warm air supply equipment is sent to the inside of the air chamber 14a of the air tent 4 through the ventilating pipe 22a. It is circulated in the air chamber 14a to heat accumulated snow on the membrane 4a. As a result, the snow is melted away, and it is removed from the top of the membrane 4a. A warm current of air is supplied only to the inside of the air chamber 14a, and the warm air supply equipment can be miniaturized accordingly.

摘要： PROBLEM TO BE SOLVED: To make it possible to color an air tent. SOLUTION: Two transparent membranes 4c and 4d having a circular shape in a plane view are arranged between light transmitting membranes 4a and 4b forming an air tent, and an air chamber 14a is formed. A plurality of air inlets 20a linking with the air chamber 14a are provided to the periphery thereof, and while, a plurality of exhaust ports 20b linking with the air chamber 14a are formed in the periphery of the air chamber 14a on an opening side in the center of the air tent 4. A ventilating pipe 22a is connected to the air inlets 20a, a ventilating pipe 22b is connected to the exhaust ports 20b, and dampers are provided to the ventilating pipes 22a and 22b. When coloring is executed, for example, light transmitting red beads are sent into the air chamber 14a from the ventilating pipe 22a though the damper, and the air chamber 14a is filled with them. As a result, the air tent itself is colored.

摘要： PROBLEM TO BE SOLVED: To make it possible to absorb sound of an air tent. SOLUTION: Two membranes 4c and 4d having a circular-shape in a plane view are arranged between membranes 4a and 4b forming an air tent 4, and an air chamber 14a is formed. A plurality of air inlets 20a linking with the air chamber 14a are provided to the periphery thereof. While, a plurality of exhaust ports 20b linking with the air chamber 14a are formed in the periphery of the air chamber 14a on an opening side in the center of the air tent 4. A ventilating pipe 22a is connected to the air inlets 20a, and a ventilating pipe 22b is connected to the exhaust ports 20b. When sound absorption is executed, sound absorptive fiber lump is sent to the inside of the air chamber 14a through the ventilating pipe 22a, and the air chamber 14a is filled therewith. As a result, a space between a space under the air tent 4 and an outside space is acoustically cut off, and inside sound does not leak to the outside, and on the contrary, no outside sound enters the inside.

摘要： PURPOSE: To improve functionality as event-facilities by changing the dimming physical properties of a dome canopy membrane and by a gas, to promote the melting of snow. CONSTITUTION: A dome canopy membrane consists of transparent or semitransparent double membranes 1 having gas sealing properties, a feeder composed of a compressor 2 supplying the inside of the double membranes 1 with a gas having dimming physical properties for realizing light conformed to light required in a dome, a reservoir tank 5, a supply tank 6, etc., is mounted. When snow should be melted, the inside of the dome is heated by a heater apparatus 7 at the time of the supply of the gas, and snow is melted while being separated from heating in the dome.

摘要： PURPOSE:To prevent snow from melting by disposing selectively a roof on a slope in accordance with a solar radiation condition by driving to cover and open the roof against the slope by a roof opening/closing control means in accordance with the heat radiation income/outgo quantity of the slope detected by a heat radiation income/ outgo quantity detecting means. CONSTITUTION:In the upper part of a slope 2, a roof 9 is formed so as to freely drive to cover and open the slope 2, and a radiation income-outgo meter 11 for detecting the heat radiation income/outgo quantity of the slope 2, and a heat radiation income- outgo quantity detecting means of a radiation income/outgo quantity detecting means as a radiation income/outgo quantity detecting part 19, etc., are equipped. Also, this equipment is provided with a roof opening/closing control means such as roof opening/ closing deciding part 17, a winch driving control part 21, a winch driving 61, etc., for controlling driving to cover and open the roof 9 against the slope 2 in accordance with the heat radiation income/outgo quantity of the slope 2 detected by the heat radiation income/outgo quantity detecting means. In accordance with the heat radiation income/outgo quantity detected by the heat radiation income/outgo detecting means, the roof opening/closing control means drives to cover and open the roof 9. In such a way, show melting on the slope 2 can be prevented, and it can be executed easily to maintain a snowfall and to secure a condition of the slope.
