Abstract: A tank apparatus and a system for dispersing by circulating a mixture that prevents powdery additives from adhering to an inner face of a tank from scattering in the tank, from drifting on the surface of a liquid, and from agglutinating, are presented. The tank apparatus that stores a raw material that is slurry or liquid and supplies powdery additives to the raw material to mix them with the raw material comprises a tank for storing the raw material and a screw-type device for supplying powdery additives that is integral with the tank and supplies the powdery additives to the raw material in the tank, wherein a tip of a part for supplying powdery additives of the screw-type device for supplying powdery additives is inserted into the mixture in the tank.

Abstract: A system and a method for dispersing by circulating a mixture that simplifies the structure of the part for sealing a shaft of a dispersing device and lengthens the life of the device are provided. The system for dispersing by circulating a slurry or liquid mixture to disperse substances in the mixture comprises a rotating and continuously dispersing device that disperses the mixture, a tank that is connected to an outlet of the dispersing device, a circulating pump that circulates the mixture, and a piping that in series connects the dispersing device, the tank, and the circulating pump. In the dispersing device the outflow of the mixture is greater than the inflow so that an amount of the mixture in the dispersing device is maintained at a level where a part for sealing a shaft that is provided inside the dispersing device is not immersed.

Abstract: The present invention provides a disperser that gives a local dispersing effect and a homogenous dispersing effect and that achieves a more efficient dispersion. The shearing disperser comprising a rotor and an opposing member that is opposite the rotor, wherein the disperser disperses a slurry or liquid mixture by allowing the mixture to pass through the disperser and outwardly between the rotor and the opposing member by centrifugal force, and wherein the disperser further comprises a plurality of gaps that are provided between the rotor and the opposing member and lead the mixture outwardly; and a buffering space that is provided to connect an outermost gap to a gap located in a position inward from the outermost gap and that retains the mixture.

Abstract: A molding process which comprises mixing together a particulate aggregate, plural kinds of water-soluble binders, a crosslinking agent causing crosslinking reaction with the binders, a phenol resin, and water, agitating the obtained mixture to prepare a bubbled fluid aggregate mixture, filling the aggregate mixture into a molding cavity, and solidifying the aggregate mixture through the evaporation of water from the mixture to give a mold made from the mixture.

Abstract: Provided is a multi-leaf spring-type vibration damping device capable of suppressing the resonance caused by rotations near the major critical speed of a rotating shaft system and suppressing self-excited vibrations due to rotations at or higher than the major critical speed of the rotating shaft system. In the multi-leaf spring-type vibration damping device, a bearing (9) of a rotating shaft system (6) that includes at least a rotating shaft (4) fit in the bearing and a rotor (5) mounted on the rotating shaft is clamped between a plurality of fixedly mounted and properly spaced-apart multi-leaf springs (11) at the portions near their distal ends, or the plurality of multi-leaf springs contact at those portions near the distal ends with the bearing, thereby to suppress the whirling vibrations of the bearing.
