  • Patent number: 10866500
    Abstract: A projection apparatus includes a plurality of two-fluid nozzles, a projection-apparatus-side-gas-flow-path, a gas valve, a projection-apparatus-side-liquid-flow-path, a liquid valve, a projector, a mist concentration measurer, and a controller. The controller starts and stops spraying of a mist by controlling the gas valve and the liquid valve on the basis of an image or a video projected onto a screen from the projector. The controller receives a signal indicating a mist concentration from the mist concentration measurer, starts and stops spraying of the mist by controlling the gas valve and the liquid valve on the basis of the received signal, and thus controls the mist concentration.

  • Patent number: 10612448
    Abstract: A cooling structure of a multi-cylinder engine is provided, which includes cylinder bores formed in a cylinder block, a water jacket surrounding the bores, a cylinder head, and a water jacket spacer accommodated in the water jacket and having a peripheral wall formed corresponding to the cylinder bores. A length of the peripheral wall in cylinder bore axial directions is substantially the same as that of the water jacket. The peripheral wall forms, inside the water jacket, inner and outer channels, and a width of the inner channel is less than that of the outer channel. Communicating holes communicating the inner and outer channels are formed in the peripheral wall at locations between adjacent cylinder bores, respectively. Inter-bore channels into which some cooling fluid flowing from the outer channel into the inner channel flows are provided to parts of the cylinder block between the adjacent cylinder bores, respectively.

  • Publication number: 20190015854
    Abstract: In a mist nozzle, a liquid stored in a liquid storage tank is pressurized by a liquid supplier and is supplied to the mist nozzle, so that a liquid flow is introduced from an upstream of a gas-liquid mixing section and a vicinity of a wall surface of the gas-liquid mixing section into the gas-liquid mixing section on an outer lid side. A pressurized gas is supplied from a gas supplier from a facing surface, so that a gas flow introduces into the gas-liquid mixing section and collides with the liquid flow, and a gas-liquid mixed flow is advanced to a spout portion while circulating the wall surface of the gas-liquid mixing section on the outer lid side. Therefore, it is possible to promote atomization of the liquid in the gas-liquid mixing section and spray a liquid having a smaller particle diameter.
