Latest Patents

Onozuka's latest patents include a fire supervising system and an extinguishing target determining system. This invention relates to a fire supervising system and a fire extinguishing target determining method in the water discharging and fire extinguishing operation. The system and method are characterized by dividing a fire supervisory region into a matrix pattern to set a plurality of sections. It identifies the section corresponding to the position of a fire from the positional information output from a fire sensor. The system selects a water discharging target for a water discharging nozzle based on a priority order set for the respective sections or selects the optimum water discharging nozzle for the fire extinguishing operation.

Another significant patent is a discharge pipe and discharge apparatus using the same. This invention features a water jet discharge pipe that produces a wide effective spray area and long water reach at low pressure and water volume. Compressed air is injected around the periphery of the pressurized water stream produced through an inner cylindrical member, which is throttled by a nozzle extending into the inner cylindrical member. The injected air prevents the reduction of the flow velocity of the water by contact with the inner wall of the cylindrical member. Additionally, external air is introduced through air inlets in an outer cylindrical member to straighten the air layer accompanying the water jet, suppressing premature dispersal of the water stream prior to ejection.
