Abstract: The present invention relates to a vibration-proofing device which supports an upper structure, such as a building, computers and other machines or a floor having such machines mounted thereon, on a lower structure, as a foundation, to allow the upper structure to swing, thereby isolating earthquakes, traffic vibrations and vibrations from the equipment installed in another room so as to protect the upper structure from vibrations. The invention is to provide a bearing type of vibration-proofing device which is simple in construction and capable of reliably absorbing not only horizontal but also vertical components of earthquakes, traffic vibrations and other vibrations, whether they are weak or strong, and which properly operates under low load and produces little vibration during operation. The invention provides an arrangement wherein interposed between upper and lower structures are rolling bodies for horizontally supporting the upper structure for swing movement.

Abstract: The present invention relates to an earthquake-proofing device wherein a superstructure is placed and supported for horizontal movement on a foundation structure so as to increase the natural vibration period of the superstructure, thereby protecting the superstructure against earthquake energy and traffic vibration. More particularly, the outer periphery of an elastic body, visco-elastic body or viscous body which hardly exhibits rigidity by itself is surrounded by a restrainer which restrains it from bulging outward, thereby enabling the body to develop high vertical rigidity while allowing it to retain horizontal deformability, the body being used as a load carrier. The restrainer and/or load carrier absorbs vibration energy by frictional damping action.

Abstract: The vulcanizing mold has an upper mold member, a lower mold member, a sector surrounding the space between the upper and lower mold members and an actuator movable upward and downward relative to the sector to move the sector radially outward and inward. The actuator is divided into an upper actuator portion and a lower actuator portion. The sector is also divided into an upper sector portion and a lower sector portion. The mold further has a connection for connecting the actuator portions together to raise the lower actuator portion by a predetermined amount with the rise of the upper actuator portion and for separating the lower actuator portion from the upper actuator portion upon the portion rising more than the predetermined amount, when the mold is opened.

Abstract: An earthquake-proofing device of peripherally restrained type including a laminate constructed by alternately laminating rigid plates and rubber-like elastic plates, the laminate being formed with a cylindrical hollow portion which opens at its opposite ends as viewed in the direction of lamination, and a visco-elastic body to be inserted into the cylindrical hollow portion to fill the latter. The earthquake-proofing device is characterized in that the volume of the visco-elastic body is greater than that of the cylindrical hollow portion by an amount corresponding to the product of the portion of the inner surface area of the cylindrical hollow portion opposed to the rubber-like elastic plates and 5-60% of the thickness of a single rubber-like elastic plate. The visco-elastic body having such excessive volume is pressed into the cylindrical hollow portion.

Abstract: A device for scattering and simultaneously filling sand into turf spaces of an artificial lawn spread on a base comprises a truck caused to run on the artificial lawn by a drive source, a hopper mounted on the truck for storing sand, and a rotary brush for filling the turf spaces with the sand discharged from the hopper and scattered on the artificial lawn. The rotary brush is rotatably driven by the drive source of the truck, and vertically movably mounted onto the truck. The rotary brush is supported by coupling members by which the urging force of the brush against the artificial lawn can be adjusted when the rotary brush is positioned upon the artificial lawn.

Abstract: The invention relates to a clamping device including a pair of recessed semicylindrical resilient gripping bodies each embedded with a resilient member of harder material than the gripping bodies. The cross section of each resilient member is shaped like a semicircle having flanges at its both side edges, respectively. The diameter of the semicircle is the greatest at the midpoint of a center axis of the reinforcing member and becomes smaller toward the ends thereof. A tubular member is securely clamped inside the recesses and between these bone members by connecting means.

Abstract: A fender beam and life ladder in one which serves as a life ladder mounted on a wall surface of a quay or the like and extending substantially vertically at least from a water level to an upper end of the quay to help a person who has fallen from the quay and which also serves as a fender beam to prevent a hull from being damaged resulting from the contact thereof with the quay when a ship comes closer to the quay. The fender beam and life ladder has a pair of plate-like elastic members, which are mounted on the wall surface so that one end widthwise of each elastic member is obliquely projected from the wall surface of the quay and the projected ends are opposed in a suitably spaced relation. On the projected ends there are provided plural steps of cross members forming a ladder in a suitably spaced relation.

Abstract: A rubber tube for dredging work embedded in and used in a pipe-line used for dredging work in the sea or river. This rubber tube has a tubular body made of rubber having a plurality of strengthening clothes embedded therein, and a plurality of metal rings axially arranged in a suitably spaced relation which are embedded in an inner peripheral surface of said tubular body and which inner peripheral surface forms a part of the inner peripheral surface of said tubular body. The metal rings have their joined surface with the tubular body placed in parallel to the axis and axial both ends thereof made thin in wall-thickness. Thereby, a contact area between the metal ring and the tubular body is increased to strengthen a bonding force and minimize a peeling off of the joined surface between both ends of the metal rings and the tubular body.
