20100213291 | TUBE-END DEVICE FOR FIRE EXTINGUISHMENT - A tube-end device for fire extinguishment jets and sprays pressurized and fed water, seawater, or aqueous fire-extinguishing agent from a tube end. The tube-end device for fire extinguishment is provided with: an induction electrode unit disposed in an emission space side of a nozzle unit positioned inside the tube end; a water-side electrode unit disposed at a position of the interior of a tube main body in contact with fire-extinguishing water; a voltage applying device which applies an external electric field, which is generated by applying a voltage between the induction electrode unit and the water-side electrode unit, to the water, seawater, or fire-extinguishing agent in the process of jetting from the nozzle unit, electrically charges jetted particles, and emit the particles; and a battery which supplies power to the voltage applying device. | 08-26-2010 |
20100304622 | CONTACT DEVICE - A contact device that has decreased contact pressure against a conductor caused by elastic repulsion force of a spring contact, to thereby enable suppressing friction and reducing electrical-resistance. The contact device includes first and second conductors arranged on a same axis and moved in their axis direction to fit to each other, a spring contact fitted to an installation groove of the second conductor, and a conductive contact piece arranged between a fitting face of the first conductors and the spring contact, so that electric current flows in a pair of conductors through the conductive spring contact and the conductive contact piece. The spring contact has an elliptical cross section formed of a bare wire being spirally wound with tilting against the winding axis thereof, and the contact piece is divided into a plurality of segments in a direction of the winding axis of the spring contact, and configured to line-contact or face-contact the other of the conductors. | 12-02-2010 |
20110186311 | FIRE PREVENTION EQUIPMENT AND SPRAYING METHOD - Fire-extinguishing agent supplying equipment pressurizes a water-based fire-extinguishing agent and supplies the agent via a pipe; and the water-based fire-extinguishing agent is pressurized and supplied via the pipe to an electrification spray head installed in a protection area A, and the jetted particles of the fire-extinguishing agent are electrified and sprayed from the electrification spray head. A pulsed or alternating electrification voltage is applied to the electrification spray head from a voltage application unit | 08-04-2011 |
20110186646 | ATOMIZATION COOLING EQUIPMENT AND ATOMIZING METHOD - Cooling water is pressurized and supplied via a pipe to an electrified atomization head installed in an atomization cooling area A, the jetted particles of the cooling water from the electrified atomization head are electrified and atomized. An electrification voltage is applied from a voltage application unit to the electrified atomization head, and the external electric field generated by applying a voltage between a water-side electrode unit and an induction electrode unit is applied to the cooling water in a jetting process so as to electrify the atomization water and facilitate adsorption to people. | 08-04-2011 |
20120000677 | FIRE PREVENTION EQUIPMENT - A wide protection range can be ensured by extending the flying distance of fire-extinguishing agent particles electrified and sprayed from a head.
