  • Patent number: 7004409
    Abstract: A number of water spray holes formed on a water spray plate is not less than 130. A diameter of the respective water spray holes is not less than 0.1 mm and not more than 0.5 mm, and an entire aperture area thereof is not more than 30 mm2. With this arrangement, since the entire aperture area of the water spray holes is reduced, it is possible to achieve water-saving effects. Moreover, since the water spray holes are small and provided by a plurality of numbers, the flow of water sprayed from the respective water spray holes is large to feel some strength hitting the skin and to achieve expansion of shower water so that the sense of using the shower may be satisfied. Moreover, since a plurality of small water spray holes is formed, a larger number of minus ion can be generated.

  • Patent number: 6994279
    Abstract: In an injection hole plate of a fuel injection device, injection holes are arranged about a circle. Fuel injected from the injection holes forms a flat sector-shaped spray. The intervals between adjacent injection holes are approximately equal to each other, while the diameters of the injection holes are equal to each other. An injection hole is positioned on an imaginary plane, which contains the central axis of the sector-shaped spray along the injection direction and is orthogonal or approximately orthogonal to the sector-shaped spray. The injection holes, away from the imaginary plane in this order, are symmetric with respect to the line of intersection of the injection hole plate and the imaginary plane. The farther each injection hole is away from the imaginary plane, the larger an angle of gradient of the injection hole with respect to the imaginary plane becomes.

  • Patent number: 6598807
    Abstract: The present invention comprises a casing with an opened end for receiving a liquid and a holding end where the liquid is stored. Between the open end and the holding end there narrow neck. A ball is placed into the opened end of the casing, so that lodging the ball into the neck will seal the neck area so that the liquid contained within the holding area will remain in the holding area until the ball is dislodged upon impact. Attached to the opened end of the casing is a nozzle. The nozzle serves two purposes, first it assures that the liquid contained within the casing does not quickly run out of the device upon impact minimizing the spray area covered by the liquid. Additionally the nozzle contains a number of holes distributed throughout the surface of said nozzle, so that the passage of liquid through the nozzle will cause the device to flail erratically, further maximizing the area sprayed by the device.

  • Patent number: 6116520
    Abstract: Disclosed is a fire-fighting nozzle integrated with a lighting apparatus. The lighting apparatus is integrally set within the housing of the nozzle so as to illuminate a target area at the scene of a fire without failure, thus allowing a firefighter to precisely spray water to the target area. The lighting apparatus comprises a bulb housing holding a bulb therein. An interior housing is longitudinally set within the nozzle housing, with the bulb housing being fitted into the front end of the internal housing. A connector is fixed to the inside surface of the nozzle housing at one end thereof without closing the water passage of the nozzle housing. The above connector is also assembled with the rear end of the internal housing through a screw-type engagement so as to allow the internal housing to be longitudinally positioned along the central axis within the water passage of the nozzle housing.

  • Patent number: 6089219
    Abstract: This application is an invention relating to an improvement in a gas burner for a stove for leading a mixed gas to flame holes, and burning the gas therein, through a gas passage (18) from a mixing tube (5) which produces the mixed gas by mixing a gas introduced in a jet from a nozzle and primary air drawn in with introduction of the gas. A sub-chamber (Ca) is provided separately from the gas passage for storing the mixed gas in a state of flux. The sub-chamber (Ca) communicates with the gas passage (18) through an inlet (3), and discharges the mixed gas stored therein through outlets (2) disposed adjacent the flame holes. With this construction, even when a continued combustion in the flame holes becomes difficult due to air-rich air resulting from an operation of an adjusting lever of the gas burner for a stove to adjusts the quantity of gas rapidly from large to small, the mixed gas stored in the sub-chamber (Ca) is discharged from the outlets (2) to continue the combustion.

  • Patent number: 6050506
    Abstract: A showerhead used for dispensing gas over a wafer in chemical vapor deposition (CVD), especially for CVD of metals. The patterns of holes is tailored to compensate for thermal and other effects, in particular by increasing the density of holes toward the periphery of the wafer in three or more zones. Such a variable pattern is particularly useful for liquid precursors that are atomized in a carrier gas, in which case a second perforated plate in back of the showerhead face can be eliminated, thereby reducing the flow impedance and the required pressure of the liquid-entrained gas, which tends to deposit out at higher pressures. The reduce flow impedance is particularly useful for CVD of copper.

  • Patent number: 5857623
    Abstract: A nozzle body and coupler bearing assembly for discharging a liquid material. The nozzle body consists of approximately thirty-two serially and concentrically arranged ports which receives liquid from an attached hose under high pressures. The various points of placement of the ports, combined with the rotation produce a balanced and stabilized effect on the rotating nozzle assembly which allows the nozzle assembly to be delivered to a target area, and while in operation, have the ability to be left unattended by fire-fighting personnel. The wild and natural whipping action exhibited from a fire hose under high operating pressures is nullified with the present nozzle. The body of the nozzle is a hollow paraboloid attached to a coupler bearing assembly. The nozzle body is made from a resilient and durable material with concavo-convex surfaces with a plurality of ports emitting liquid in a radial "Dandelion puff" pattern.
