  • Patent number: 8726918
    Abstract: The present invention provides: a nanofluid generating apparatus that has relatively simple construction, is capable of stably generating nanobubbles, is easy to handle and makes it possible to reduce manufacturing cost; and a cleaning apparatus that uses nanofluid. An apparatus for generating nanofluid containing nanobubbles, wherein the nanobubbles are gas bubbles with diameter less than 1 ?m, comprising: a gas-liquid mixing chamber 7 for mixing gas and liquid; and a pressurization pump 4 and an air intake valve 21 for supplying the pressurized gas and liquid to the gas-liquid mixing chamber, wherein the gas-liquid mixing chamber comprises therein: a turbulence generating means Z having projecting lines 9 and grooves 10, 12, and a conical section 11, for forcibly mixing the supplied gas and liquid by generating turbulence therein; and a nano-outlet 20 for turning the forcibly mixed gas and liquid mixture into nanofluid having nano bubbles and discharging the nanofluid.

  • Patent number: 5344153
    Abstract: A board game comprises a game board in which a plurality of triangular spaces are defined, within the interior of a hexagon defined by three pairs of parallel sides, by a plurality of straight lines equidistantly spaced from each other and extending in parallel to the three pairs of parallel sides of the hexagon. A central space located substantially at the center of the hexagon and three spaces located immediately adjacent thereto are different in appearance from all the other spaces. The game further comprises at least three sets of pluralities of small play pieces sized and shaped to rest respectively on the individual spaces of the game board. The at least three sets are different in appearance from each other.
