Abstract: Ultrafine powder is stored in a pneumatic transportation tank (20), and is discharged to a transporting conduit (23) while being fluidized by the pressurized air fed through a fluidizing air port (24). The ultrafine powder is fed to a weigher (30) provided at the other end of the transporting conduit (23), at which the weight of the transported ultrafine powder is weighed by a load cell (31). After the weighed value reaches 90% of a predetermined value, the fed amount of the pneumatic transportation air is reduced, and a bypass regulating valve (38) is adjusted to thus decelerate the transportation. When the weighed value reaches 100% of the predetermined value, the discharge of the ultrafine powder to the transporting conduit (23) is stopped. This method and the apparatus enable the storage, quantitative batch transportation, and automatic weighing of the ultrafine powder such as silica fume.

Abstract: A measuring technique for producing a three-dimensional image and information relating to the type of sand, clay or gravel which defines a wall or walls of a deep concealed underground excavation which is filled with a stabilizing liquid, and which technique facilitates accurate and safe construction, utilizes a transducer which irradiates a surface of the excavation with ultrasonic waves and detects the waves which are reflected back thereto. The transducer scans horizontally in incremental stages which occur with a predetermined angle pitch. After each scan is completed, the transducer is vertically displaced by a predetermined amount and the horizontal scan is repeated. The time required for a wave to reach and be reflected back to the transducer is used to determine the distance of the wall from the device.

Abstract: A weight is disposed in an arbitrary story of a structure so as to be movable relative to a direction of motion of the structure. Rotary members are supported in the weight. Rigid members meshing with gears provided on each rotary member are slidably fitted in the weight. These rigid members are respectively coupled to a ceiling and a floor via coupling members. The rotary members and the rigid members are disposed on the weight in correspondence with two horizontal directions. As a result, a horizontal motion of the floor of the structure is temporarily converted into a rotational motion by the rotary members, and is then converted into a horizontal motion so as to be transmitted to the ceiling. At this time, since the rotary members are pivotally supported in the weight, the weight can be moved in the opposite direction to that of the floor without undergoing an arcuate motion, thereby exhibiting the effect of reducing an input of vibration.
