    Abstract: PROBLEM TO BE SOLVED: To provide a snow removal tool which raises a hopper part by stepping on it in order to reduce the work of pushing and gathering snow and the work of snow disposal so as to enable snow disposal from a place away from a snow disposal site at the time of snow disposal.SOLUTION: The stepping-on type snow removal tool is provided with a hopper part comprising a hopper part supported by a frame structure 1 composed of a handle part 2 and two side frame parts and pivotably supported to be rotatable in both front ends of the frame structure 1, a pair of press frame members each fixed to a pair of slide members fixed to be slidable along a guide member, of which one end is fixed to the intermediate part between both side faces of the hopper part to be rotatable and of which the other end is fitted to the side frame part, and a cross member connecting the pair of slide members. Moreover, the stepping-on type snow removal tool is provided with tires for drive so as to enable movement on the road surface without snow.

    Abstract: PROBLEM TO BE SOLVED: To provide a water cut-off joint which is fixed by burying it into an underground structure and capable of preventing its sealing performance from being reduced even if a tensile force is generated in this water cut-off joint. SOLUTION: This water cut-off joint is composed of a joint material 7 formed on the outside of a joint part 5 between box culverts 2a and 2b and having flowability and extending and contracting properties and a belt-like water cut-off joint 1 having watertightness and extending and contracting properties and provided on the inside of the joint 5 for the joint material 7. This water cut-off joint 1 includes a first sheet body 11 positioned on a joint material 7 side in a central part 10 of the joint and a second sheet body 12 positioned on the inside of the first sheet body 11 and having a flexible part 29 in the direction of its width. Lateral strain of a pair of sheet-like joint blade parts 14 formed to extend from both sides in the direction of width of the central part 10 of the joint and buried in each of the box culverts 2a, 2b is set to be smaller than the lateral strain of all the synthetic rubber on the assumption that the tensile force to be generated is the same.

    Abstract: PURPOSE:To simplify maintenance and to save material by preventing valley type shifted abrasion of collector shoe due to bent trolley at a curve. CONSTITUTION:Cross-sectional area, width or thickness of a sliding board mounted on a pantograph are set smaller at the opposite ends than at the central part thus preventing shifted abrasion. Furthermore, cross-section of only first main sliding board 2 may be made uniform or first and second main sliding boards 2, 3 may be integrated.

    Abstract: PURPOSE:To hold a high fail-safety of the whole device by providing a signal detector which has a high fail-safety and a lower detecting sensitivity than that of each speed signal detector to the ATC receiver. CONSTITUTION:A signal from the ground transmission line SL of ATC is detected by the car antenna CA, the ATC signal is received through the matching transformer CT irrespectively of the sorts of speed and is fed to the circuit DE, which detects any of signals transmitted from the ground, to operate the relay DETR, Circuits V1D1 to VnD2 are the ATC speed signal detectors of duplex system and operate the relay V1R to VnR by OR gates OR1 to ORn. Also respective outputs V11 to Vn2 of the duplex circuits V1D to VnD2 are fed to the ''or-else'' circuits X0R1 to X0Rn, action contacts of the relay DETR are inserted in the output side of X0Ri.
