Abstract: A method for measuring three-dimensional displacement of a mass comprises the steps of providing a measuring object placed on the end surface of the mass, for reflecting at least a fraction of three-dimensional displacement of the mass, arranging a displacement measuring equipment for free displacement relative to the mass and in opposition to the measuring object, and measuring three-dimensional relative displacement of the mass by detecting relative displacement of sad displacement indicative means relative to the displacement measuring equipment by the latter.

Abstract: In a management system for a water-barrier sheet having a double layer structure with an upper sheet and a lower sheet, the interior space of the water-barrier sheet is hermetically sealed and divided into a plurality of enclosed divisions. A vacuum source introduces vacuum into each enclosed division. Pressure sensors monitor the vacuum condition in the inside of the respective enclosed divisions and a faulty division among them is identified by variation of the vacuum pressure when failure is caused. In response to detection and identification of the faulty division, a repair operation is performed. In case that penetration of water into the ground is not detected, temporary treatment for preventing the water penetration may be made by introducing pressurized air into the faulty division. For permanent repair of the division, water stop material is injected into the faulty division.

Abstract: A hydrostatic anti-vibration system includes a main tank provided on a construction to be suppressed from vibrating and having a main tank body of substantially flat rectangular configuration. Hollow vertical extensions extend upwardly from peripheral edge portions of the main tank body and are filled with a working liquid at a predetermined level with upper air chambers maintained thereabove. Ducts communicate the upper air chambers of the hollow vertical extensions. Intermediate tank portions are disposed at the intermediate portions of respective ducts and contain a vibration suppressing liquid. A pivotal plate is disposed in each of the intermediate tank portions to separate the interior space of the intermediate tank portion into a pair of chambers respectively connected to corresponding portions of the duct. The plate pivots in response to flow pressure of the vibration suppressing liquid. A damping mechanism provides a resistance against displacement of the pivotal plate.

Abstract: A concrete product which uses 100% of the melt slags and pulverizes the melt slags into aggregates and fine powders, grinds the aggregates so that the percentage of absolute volume of the aggregates is over 60%, mixes the aggregates, fine powders, water and cement, and forms the mixture into the concrete product by vibration or press molding.

Abstract: A three-dimensional displacement measuring system measures the three-dimensional displacement of a mass such as rock. A first cylindrical member is provided as a displacement indicating device and is arranged on one side of a discontinuous surface, such as a crack, in a bore hole in the rock. The bore hole extends across the discontinuous surface. A second cylindrical member is provided as a displacement measuring device on the other side of the discontinuous surface and is free to displace relative to the mass and the first cylindrical member and is located opposite to the first cylindrical member.

Abstract: A cable crane system includes a main cable stretched between two points, a transverse trolley traveling along the main cable, a traction cable for driving the trolley, a bucket hung by a hanging cable, a transverse winch for driving the traction cable for driving the trolley between a transportation start position to a transportation end position, a vertical winch for retracting and extracting the hanging cable for lifting the bucket up and down, and driving means for the transverse and vertical winches.

Abstract: A waste disposing ground or facility includes a space in the form of a cavity for receiving waste therein. A planar structure covers the entire overall upper opening of the cavity. The planar structure is constructed in advance of starting disposal of waste into the cavity. Arranged on the lower surface of the planar structure is a system for spraying water on the waste. Disposed at the bottom of the cavity is a system for discharging air. Since air can be discharged from the bottom of the cavity that is closed by the planar structure, the atmosphere surrounding the waste in the cavity can be changed from an anaerobic state to an aerobic state. Since water is supplied on the waste, decomposition of organic substances which decompose under aerobic conditions can be promoted. If air is not discharged from the air discharging system, the waste is placed in an anaerobic condition, and decomposition of the organic substances which decompose under such conditions can be promoted.

Abstract: The low temperature food storage equipment of the present invention is provided with an icehouse and a food storeroom each surrounded by a heat insulator. The icehouse and the storeroom are connected by a detachable heat exchanger disposed therebetween. In the icehouse there is stored water which is frozen into ice when the outside air grows cold. In the storeroom there are kept in cold storage a large amount of shippable food, for example, potatoes. In the case of shipping the food, the heat exchanger is removed and the food is transported on a truck or the like while being kept in cold storage in the storeroom.
