摘要： PROBLEM TO BE SOLVED: To accelerate training effects equivalent to a highland training by providing accommodations formed by decompressing inside a building near a training facility under the decompressed environment and by training while staying there for a prescribed period. SOLUTION: Accommodations, a habitable facility, and a machine room 9 provided with an air conditioner and a decompression device 10 are provided inside a building 1 near a training facility under the decompressed environment such as an underground cavity, the indoor temperature and humidity are adjusted, and the air pressure is held to 0.7 atm, approximately same as that of a highland of the altitude 3,000 m or less. It is also provided with an adjustment room 12 for adjusting the outdoor and the indoor air pressure in coming in/going out the building 1 and an emergency exit 14. A few athletes stay in the building 1 at all times for a prescribed period and go to/from the training facility so as to train under the decompressed environment similar to the highland. After finishing the training, the athletes live under the decompressed environment at all times without returning to the normal pressure so as to accelerate the training effects further.

摘要： PURPOSE:To make direction change easy and sure by having No.2 transport means like a carrier capable of shifting in a changing direction stood by at a direction change point, having No.1 carrier which had been transporting a heavy article run over the transport means, and shifting with No.2 transport means together with No.1 carrier. CONSTITUTION:A heavy article is transported by No.1 transport means W consisting of rubber tube rollers 1, 1 and a frame 2, lowered down to a level flush with road surface 6, and made to run over onto No.2 transport means K which is linked with a gangway not shown in the figure. Next, a separate set of H steel 7a, 7a are inserted among the rubber tube rollers 1, 1, the rubber tube rollers 1, 1 are deflated and the rubber roller tubes are pulled out. The roller tubes 1, 1 are inserted beneath the frame 2a, and the article is transported on rollers in the direction to be changed. The constitution makes it possible to easily and surely change the direction.

摘要： PROBLEM TO BE SOLVED: To reduce the construction period by turning partial roofs to the circumferential direction along a ring-shaped guide supporting the arcuate side of the partial roof after the partial roofs have been constructed one by one at a specified place at the opening side and positioning them. SOLUTION: A cylindrical continuous underground wall 3 is provided in the ground 1 and a recessed part is formed in the ground 1. Support members 24 are radially fixed onto the one side bottom face of the recessed part and a plurality of supports 25 are fixed on the support members 24 and further, jacks 26 are fitted onto the supports 25. A plurality of concrete forms 27 are arranged on the jacks 26. Concrete is placed on the forms 27 and hardened to form a semicircular dome-shaped roof element 6a. Other jacks 26 except the central jack 26a are lowered and the roof element 6a is rotated by a half turn around the supporting point and fixed therein. Thereafter, the other half elements 6a is constructed again to form the roof. Support members 24 or the like are taken out and then, the ground is excavated and after the bottom slab, the side wall, etc., are formed, a cover layer is put thereon to form an underground tank. In this way, the construction period can be reduced.

摘要： PURPOSE:To move a piston in a cylinder via a rod as well as to feed a required spot with seawater in the cylinder from a discharge pipe by utilizing pressure by wave force of the seawater sand head difference, and rocking a pressure receiving plate with a hinge fulcrum. CONSTITUTION:When wave energy of seawater W works on a pressure receiving plate 7, this plate 7 rocks, thereby moving a piston 6 so as to expand the inside of a cylinder 1. Therefor the inside of this cylinder 1 comes to negative pressure, a check valve 4 in a suction pipe 2 is opened, and thereby the seawater is sucked in the cylinder 1. On the other hand, when the wave energy works from the reverse direction, the piston 6 is moved in direction of compressing the inside of the piston 1 by rock motion of the pressure receiving plate 7. Consequently, the check valve 4 of the suction pipe 2 is closed and simultaneously a check valve 5 of a discharge pipe 3 is opened instead. With this constitution, the seawater W is fed to a required spot from the discharge pipe 3.

摘要： PROBLEM TO BE SOLVED: To improve the classification efficiency when classifying sand- components from the earth and sand dredged from the bay coast, effluent rivers, etc., and to execute stable classification treatment even when the flow rate of the dredged earth and sand fed to the device fluctuates. SOLUTION: The flow rate of the muddy water supplied to negative pressure type liquid cyclones 50a to 50b and negative pressure type liquid cyclones 50c to 50d, is set at 1,200 m3/H larger than about 1,100 m3/H which is the flow rate of the raw water to be introduced into a feed sump 30 and the muddy water (flow rate; 1,100 m3/H) discharged from the risers of the liquid cyclones is returned to a sealing tank 40 connected to the feed sump 30. The excess muddy water (flow rate; 1,000 m3/H) is discharged at the supernatant liquid of the sealing tank 40.
