摘要： PURPOSE:To discharge residual earth from excavation easily by coupling the first and second shafts having screw vanes by a universal joint, installing pipes at the peripheries of the shafts, providing an opening and hopper at the pipe near the bottom of the second shaft, and furnishing a discharged earth hole at the pipe near the top of the first shaft. CONSTITUTION:When a hydraulic motor 1 is driven, the power is transmitted to the first shaft 6b and forwarded through a universal joint 9 to the second shaft 6a. When the residual earth M from excavation at the bottom of a pit H is cast into a hopper 10, the earth M intrudes to a below situated bent pipe 5a and is transported upward aslant by a screw blade 7a in continuous spiral form. The conically shaped earth M reaches the universal joint 9, is disturbed by aux. vanes 8, ...8 which rotate in an irregular arc of circle, and intrudes into a vertical pipe 5b. The earth M in small lumps having intruded into the vertical pipe 5b is transported upward right over by another screw blade 7b in continuous spiral form and exhausted above the ground from an exhaust earth hole opened at the top of the vertical pipe 5b.

摘要： PURPOSE:To collect earth and sand piled up on a water bottom efficiently by installing each of separated screw blades in a ramp and a sand collecting part of a steel pipe sand discharger installing aslant ranging from a sediment collecting barge to the water bottom, respectively. CONSTITUTION:A horizontal sand collecting part is formed in the tip of an inclined steel pipe sand discharger 22, and two unconnected screw blades 20 and 24, separated from each other, are installed in a ramp and the sand collecting part, respectively. An upper part of the ramp of this steel pipe sand discharger 22 is locked to a support stand 18 of a sediment collecting barge 3. Then both these screw blades 20 and 24 are rotated and driven, whereby earth and sand on a water bottom are collected, conveying them in the steel pipe sand discharger 22, and they are collected in a sediment reservoir 8 of the sediment collecting barge 3. In this connection, a movable fin 30 being remote-controllable is installed at the outside of a cover 28 of the sand collecting part, and when the steel pipe sand discharger 22 is taken in tow up to the collecting position, depth of the sand collecting part at the tip is made so as to be properly kept up intact.

摘要： PURPOSE:To reduce a large fluctuation of tension, generated when a metal wheel passes, by dividing an anchor clamp into two or more short scale units and mounting them separately to an electric wire and a protector, divided into two or more pieces, between the respective short scale units. CONSTITUTION:An aluminum clamp, formed in long size, is not constituted of a single rigid unit but divided into two or more short scale aluminum clamps 2 which are mounted to coat an electric wire 1 with a suitable distance apart. In a connection part of the electric wire 1 to an insulator train, a steel clamp 2a is press-mounted to coat-mount the short scale aluminum clamp 2 thereon. Each aluminum clamp 2 is left as it is or mounted with a protector to allow a metal wheel to pass. The protector is constituted of many pieces and provided with free flexibility. In order to connect a jumper wire, the aluminum clamp 2 is inserted into a groove 3b of a clevis type collector terminal 3 and fixedly tightened by a tightening bolt 3a.

摘要： PURPOSE:To arbitrarily select a measuring place and to enhance measuring accuracy by receiving the signals transmitted from a plurality of artificial satellites by receiving antennae and applying operational processing to receiving waves. CONSTITUTION:Artificial satellites 10 are loaded with atomic clocks and extremely accurate signals of frequencies of about 1.2GHz and about 1.5GHz are transmitted from said artificial satellites 10 and opened popularly to be freely receivable on the earth. Antennae 31, 32 are respectively arranged at points P, Q and, on the basis of the clocks at the respective points P, Q, the phase angles of electric waves are measured. A delay time t is generated in the arrival of the electric wave 11 at the point P with respect to the point Q and appears as the phase difference between the receiving waves. The signals respectively received at the points P, Q are converted to electric signals by receivers 51, 52 and stored phase data is subjected to operational processing by a processor 8 to make it possible to calculate a distance S from the above- mentioned phase difference.
