摘要： A water jet discharge pipe which 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 and which is throttled by a nozzle extending into such inner cylindrical member. The injected air prevents reduction of the flow velocity of the water by contact with the inner wall of the cylindrical member. In addition, external air is introduced through air inlets in an outer cylindrical member extending from the inner cylindrical member so as to straighten the air layer accompanying the water jet exiting from the inner cylindrical member and suppress premature dispersal of the water stream prior to ejection from the outer cylindrical member. After such ejection, expansion of the injected air atomizes the water stream to provide large area coverage thereof.

摘要： A system and method for detecting a fire source in a supervised region by means of fire detectors which effectively scan all over such region. A plurality of reference fire sources of the same geometric shape of the minimum size to be regareded as a fire are assumed to be located in successive predetermined position on the floor of the supervised region. Vertical control means successively sets the vertical deflection angles of each detector along the respective straight lines from each detector which graze by the upper end of the respective fire sources and to the lower end of the succeeding fire source. The system also comprises horizontal control means for causing the detectors to horizontally scan the supervised region. Upon detection of a fire, the detectors provide fire detection signals to a central processor unit which then actuates a spray nozzle to direct fire extinguishing fluid on the fire.

摘要： An ionization smoke detector of the present invention has an annular engaging flange portion formed integrally on the periphery of an insulating board and an engaging groove formed on a cover, so that a circuitry-accommodating portion may be moisture- and gas-tightly sealed merely by inserting the flange portion into the groove, without using special sealing members such as ruber packing members.In an intermediate electrode mounting structure of the present invention, support legs are formed integrally on the periphery of the intermediate electrode which may be simply inserted into an opening of the insulating board to fix and support the intermediate electrode, without using screws etc. Thus, a space needed to mount the intermediate electrode can be minimized. An electrode lead is connected to a lead of an FET insulatedly potted at an appropriate place on the backside of the insulating board with a hot melt synthetic resin. This can prevent possible penetration of moisture or corrosive gases into the circuitry-accommodating portion by the insulation sealing of the FET, even though the electrode lead passes through an opening of the insulating board. Thus, corrosion of the circuit parts can surely be avoided.

摘要： The present invention provides a method and apparatus for counting the number of occurrences that a mobile unit comes within range of a stationary unit. The invention is useful in counting the number of laps which a runner or swimmer completes through a course. In one aspect, the present invention includes a timer which, in cooperation with the information generated by the lap counter, produces information corresponding to the lap time, average minutes per mile and other such data. In a preferred embodiment, a stationary transmitter emits an infrared signal to create a zone of detection which triggers a receiving unit attached to the runner or swimmer each time the runner or swimmer passes through the zone of detection.

摘要： An analog fire detecting system in which a plurality of sensors produce analog data corresponding to a physical state such as temperature, smoke density, etc. relevant to a fire condition. The values of such analog data are compared with a predetermined threshold level, and if the threshold level is exceeded the analog data is transmitted to a central station in response to a polling signal therefrom. A CPU in the central station determines, from the analog data from the sensors, if there is a possibility of a fire and if so makes a predictive calculation of the remaining time until a fire condition will be reached. An alarm is given when such predicted time falls below a preset interval.
