摘要： PURPOSE:To prevent the rotary flow of the liquid stored inside by installing a rotary blade having a direction blade formed in straight line form in a tank, around the center of the tank and installing a damping blade made of porous material in the direction crossing at right angles with the direction blade. CONSTITUTION:When a structure 6 is oscillated in the C-D direction, a wave motion 3b in the C-D direction is generated on the liquid 3 in a tank 2, and a direction blade 5 is applied with a force in parallel to the C-D direction, and turns in the A-B direction around a rotary shaft 5a, and the blades 5b and 5b shift in parallel to the C-D direction. The turning moment around the shaft 5a which is generated by the action of the wave motion 3b of the liquid 3 over and below the blades 5b and 5b onto the blade 5b is balanced, and the rotary blade 5 is stopped and held at this position. Then, the wave motion 3b passes in the C-D direction in the damping blades 5c and 5c, and the wave motion 3b is attenuated, and the vibration energy of the structure 6 is effectively attenuated. Further, the tank 3 is half divided by the blades 5b and 5b, and no flow is generated in the liquid in the vertical direction.

摘要： PURPOSE:To lessen horizontal and vertical swings of a crane by furnishing a coupled water tank body to which a plurality of division tanks storing liquid are connected through communication pipes, equipping the machine body with a vibration damping device fitted with a plurality of such water tank bodies, and furnishing resistance members in the division tanks and the communication pipes. CONSTITUTION:A coupled water tank body 6d is furnished, with which a plurality of division water tanks 6b storing liquid are connected through communication pipes 6c, and the machine body 3 is equipped with a vibration damping device 6 consisting of a plurality of such coupled water tank bodies 6d, which are arranged so that the division water tanks 6b will be in the form of a ring. Resistance members 6e, 6f are furnished in these communication pipes 6c and division water tanks 6b. When a tower crane 1 moves a boom 5 in the direction of C, D and rotates the machine body 3 in the direction of A, B, the body 3 including an operator table 3a travels horizontally and vertically. For horizontal swing, the liquid 4 in the division water tanks 6b is hindered to flow by the resistance member 6e, while for the vertical swing, the fluid 4 is hindered to flow by the resistance member 6f in the communication pipe 6c.

摘要： PURPOSE:To permit unmanned operation of an excavator for pneumatic caisson by a method in which binaural mikes are set on the positions corresponding to both ears of a worker sitting on the operation seat of an excavator in such a way as to enable him to catch surrounding sounds exactly. CONSTITUTION:A dummy model 25 like man is sat on the operation seat 6 of an excavator 1 for pneumatic caisson and binaural mikes 26 having the same acoustic constitution as human ear are set on both sides of the head model 25a. The output of collected sounds is connected to a head phone 30 attached to a worker 27 who makes driving operation in an operation room 29 on the ground's surface. The worker 27 can exactly catch the surrounding sounds of the excavator 1 for pneumatic caisson on the ground's surface.

摘要： PURPOSE:To enable a body falling in high-speed to be soft-landed by arranging a vacuum vessel and an gas braking vessel in series, and providing a vacuum barrier capable of being broken by the falling body, at the lower part of the vacuum vessel. CONSTITUTION:A vacuum vessel 1 and a gas braking vessel 2 are arranged in series. A body 3 is freely dropped from the upper part of the vacuum vessel 1, and the body 3 breaks a vacuum barrier 4, which is fixed at the lower end of the vacuum vessel 1, to reach a braking piston 5 which is stopping at the upper part of the gas braking vessel 2. The body together with the braking piston 5 falls down in the gas braking vessel 2, in the meantime, it receives braking action due to the cushion action of the gas. Thus, the body falling in high-speed can be soft-landed, so that the breakage of machineries inside the body can be prevented.

摘要： PURPOSE:To sufficiently mix excavated soil with a chemical grout with stirring under a condition where leakage is prevented by relatively turning a resistance blade and an excavating blade. CONSTITUTION:A rotary current 1 is provided to the lower end of a rotary shaft 2 having a chemical grout-passing pipeline 4 inside. Excavating blades 21 and resistance blades 22 are provided through a speed change gear 20 around the shaft 2 in such a way that the blades 21 and 22 are turned with relatively different speeds around the shaft 2 by means of the gear 20. When the shaft 2 for turning a rotary cutter 1 is turned, since the blades 21 and 22 are turned with different speeds to different directions, cohesive soil is cut between the blades 21 and 22 and an improving agent is well dispersed into the cohesive soil.

摘要： PURPOSE:To prevent the adhesion of a sticky material to a sampler, by inclining the inner peripheral surface of the blade part provided to the leading end of a cylindrical sampler main body internally toward the leading end thereof and protruding a root part end of said main body so that the outer peripheral surface is externally inclined in a leading end sharpened state. CONSTITUTION:The leading end blade part 1a of a sampler main body 1 comprising a metal cylindrical body is constituted so that the inner peripheral surface is formed into a first inclined surface 2 internally inclined toward the leading end thereof and the outer peripheral surface thereof is formed into a second inclined surface 3 externally inclined toward the rood part thereof. The inclined surfaces 2, 3 are provided so as to be intersected at a sharp angle at the leading ends thereof and the inclined surface 3 is formed so as to be protruded from the outer peripheral surface of the sampler main body 1. When this sampler is pushed in a sticky material to collect a specimen to be tested, the sticky material is almost not adhered to the sampler and specimen sampling efficiency becomes well. Because no water is used at the time of collection, for example, this sampler can be used in a substance formed by solidifying radioactive waste by asphalt.
