摘要： PURPOSE:To prevent melting of ice and snow dispersed over an artificial skiing ground. CONSTITUTION:A screw conveyor 6 capable of freely feeding ice and snow 60 manufacturing by an ice making device 2 and stored at an ice storage chamber 3 is connected to a feeder 7 to which the delivery end side of an ice snow force feed pipe 30 installed in a slope and air 50 is connected to a feedable blower 9. A line 38 through which the ice snow force feed pipe 30 and a blower 6 are intercommunicated is formed and an anemometer 11 to detect a wind velocity V in the line 38 is arranged. From the wind velocity V, an airflow wa in the line 38 is detected and an ice feed amount Wi is controlled through regulation of a drive amount of the screw conveyor 6 according to the wind velocity Wa and through the control thereof, a mixture ratio M shown by Wi/Wa is held at a given value Mn. As a result, the ice snow 60 is fed in an arbitrary low airflow with a pressure by means of air without choking the line 38 with the ice snow 60 and the ice snow 60 is prevented from being broken into small pieces.

摘要： PURPOSE:To always hold the slope sliding surface of an indoor artificial skiing ground in a state that it is suitable for skiing. CONSTITUTION:The formed slope floor structure 1 is constituted by providing a slope floor 5 on which the lay snow surface 5a capable of lying artificial snow 30 is formed, providing a water collecting duct 8 on the slope floor, providing a water collecting hole 11a in the water collecting duct 8 in a shape opened to the lay snow surface 5a, connecting a hot air supply device to the water collecting duct 8 so that snow melting air 27 can be supplied freely into the water collecting duct 8, and connecting a waste water duct to the water collecting duct 8. Subsequently, by melting the artificial snow 30 by heat of the snow melting air 27, the sliding surface is lowered. In such a way, on the lowered sliding surface 35, the artificial snow 30 like powdery snow can be further lay by a lowered height portion of the sliding surface, therefore, the sliding surface 35 is always held within allowable height, and also, can be maintained in a state being suitable for skiing.

摘要： PURPOSE:To efficiently convey artificial snow made from ice by a method wherein when the snow is supplied to a snow intake in a steep slope area, the snow is conveyed by a snow conveyer and taken over to snow pressure- conveying pipe from a snow spout, and in a gentle slope area, it is conveyed by air pressure through a snow conveying space in the snow conveying pipe. CONSTITUTION:A snow conveying line 3, which includes artificial snow supply devices 2 and 51 capable of supplying artificial snow 60 made from ice and consists of a gentle slope region 3A and a steep slope region 3A, is established along a ski slope 40. In the gentle slope region, a snow pressure-conveying pipe 52 having a snow conveying space 5s inside is laid along the snow conveying line 3 to convey the snow 60 by air pressure through the snow conveying space 5s. In the steep slope region, snow intakes 9a and 19a and a snow spout 7b are provided respectively at the lower and upper ends of the steep slope region 3B, snow conveyers 6 and 6' are installed so as to connect the snow spout 7b and the snow conveying space 5s of the snow pressure conveying pipe 52 and the snow intakes 9a and 19a are connected to the snow supply devices 2 and 51. Thereby, the artificial snow 60 can be efficiently conveyed.

摘要： PURPOSE:To enable all dwellers at both upper and lower floors of a floor, where a fire has occurred, to escape therefrom safely without fail. CONSTITUTION:An internal passageway 2 is installed in the central part of a building, and an additional room 3 equipped with a pressurized smokeproof system is set up adjacently in this internal passageway 2 via a first smokeproof door 4 open to the side of the additional room 3. This room 3 is adjoined to a staircase 6 via a second smokeproof door 5. On the other hand, in a high-rise multiple dwelling house made up of setting up each house door 7 in an outer circumferential part of the internal passageway 2, a pressure-relief device 10 is installed in a boundary wall 9 between the room 3 and the staircase 6 aside from the second smokeproof door 5. With this pressure relief device 10, pressure in the additional room 3 is set so as to escape to the side of the staircase 6.

摘要： PURPOSE:To simplify the damping structure by a method wherein a plurality of opinings are provided through a building in a vertical direction and various kinds of pipes are connected together in each opening so that the pipes are able to vibrate independently from the structures of the building and also viscoelastic dampers are interposed between the structures and pipes so that the pipes serve as auxiliary mass for vibration mitigation. CONSTITUTION:A plurality of shafts 35, each extending vertically through an opening 31a, are provided at predetermined locations through the interior of a multi-story building 30 and a group of pipes, wherein pipes 2 for water, gas, electricity, etc., are combined together, is vertically provided in said shaft, allowing the pipes to freely vibrate. Further, each unit pipe 2A of the pipes 2 is supported on a floor 31 by means of viscoelastic pipe supporting devices 10, 11 each having viscoelastic damper, whose both ends or one end are supported. If the building 30 vibrates horizontally, resonance of the group of pipes 4 comprising unit pipes 2A, 2B, 2X occurs and the vibration of each pipe 2 is damped by the damper 5. Consequently the vibration energy of the building 30 is turned into the vibration energy of the pipes 2 and the damping energy of the dampers 5, so that the vibration of the building 30 is damped.

摘要： PURPOSE:To inspect the pipe leakage of a completed portion even when the water feed system on the upstream side is not completed yet and dispense with the air releasing work before inspection and the water draining work after inspection. CONSTITUTION:The air of the preset pressure is filled and sealed in a pipe 20 by a compressor 2. The pressure of the air in the pipe 20 is measured by a pressure gauge 3 for a fixed inspection period. The measured result of the pressure by the pressure gauge 3 is recorded by a microcomputer 5. When the reduction of the pressure is large, an alarm is issued from the microcomputer 5 even before the inspection period expires.
