IPC: A62C31/02
Filed: 1990-03-13
Abstract: PURPOSE: To obtain a specially pertinent spray nozzle for a fire extinguishing in the case of having a narrow space or a space-limited passage by providing a mixing chamber with an outlet to be fitted for discharging the mixture of a gas/liquid as a spray having an ovalshaped section. CONSTITUTION: A mixing chamber 6 is a toroid having a half circular and vertical section. That is, the shape of the mixing chamber 6 is demarcated by a circle to be moved through an oval-shaped passage in the vertical surface of a circular surface. An air is supplied under a pressurization through a ring- shaped supply passage 16 and a gas inlet 10 communicated to the mixing chamber 6 of a nozzle installed. For example, a water is supplied under the pressurization through the supply passage 16 and the liquid inlet 10. The gas and liquid are discharged through an outlet 12 as a spray shape having an oval-shaped transverse section after mixed by a toroidally mixed pattern in the inside of the mixing chamber 6 by crushing and shearing each other while initiating the formation of a spray.  For example, in order to make a fire extinguishing, a spray curtain is formed toward the front along the passage of a door.

Title: Gas meter having seismic sensor device
Inventor: NUKUI KAZUMITSU
IPC: F23N5/24
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To correctly perform the shutoff of a shutoff valve or the return prohibition by shutting off the shutoff valve when the output of a comparator indicates the oscillation over the first oscillation, and prohibiting the return after shutting off the shutoff valve when the output of the comparator indicates the oscillation over the second oscillation larger than the first one. SOLUTION: The analog signal wave 21 of a seismic sensor device 20 is outputted to an LPF 22, and the output wave 23 of the LPF 22 is fed to comparators 42, 44, 46, respectively. The amplitude of the fed output wave 23 is compared with the reference value by the respective comparators 42, 44, 46, and the signal of the compared result is fed to a microcomputer 26. The microcomputer 26 generates the shutoff command signal to the shutoff valve 40 when the oscillation indicates the seismic intensity of >=5, and feeds the current to an electromagnetic coil for shutoff. In addition, in the case of the seismic intensity of >=7, the return prohibitive mode is made in the microcomputer 26, and the return of the shutoff valve 40 after shutoff is prohibited. Thus, the shutoff of the shutoff valve 40 and the return prohibition can be correctly performed.

Title: Communicating method of loop network
Inventor: KINO SHIGENORI
IPC: H04L12/433
Filed: 1982-04-09
Abstract: PURPOSE:To attain effective use of a loop even if a station transmitting a great deal of data exists in a loop, by using a part of a vacant loop by an extra- token. CONSTITUTION:Let a data from a station (ST) 3 to other STs longer than the other data. Then the ST3 informs that the data are large in quantity to a controller 7. When a loop adaptor 2 catches a token, the controller 7 outputs an extra-token transmission request to the other Sts and the extra-token signal is transmitted from the adaptor 2 of the other STs to a loop 1. Thus, the partial use of the loop 1 is made possible. When the ST3 completes the data transmission and receives an extra-token in using the station as the final station, the original token is outputted to the loop 1 and the extra-token is abandoned, then the token and the extra-token are never circulated on the same loop.

Title: Pulse arc welding equipment
Inventor: MIZUNO KOUJI
IPC: B23K9/09
Filed: 1979-05-17
Abstract: PURPOSE: To make setting of welding conditions easy by controlling the output of a base electric power source according to the output of a pulse electric power source so that the mean output voltage of the pulse arc welding electric power source equipment is not changed.  
     CONSTITUTION: It is assumed that the closer the sliders of variable resistors 3, 5 go toward the negative constant voltage source side the larger the output voltages of the base electric power source and pulse electric power source become. Here, if the slider of the resistor 5 is moved to the negative constant voltage source, the output voltage of the pulse electric power source becomes large and at the same time the set value e s2  of the resistor 5 is inverted of its phase by a phase inverter 24 and is transmitted to a differential amplifier 16. Because of this, the output signal of an amplifier 16 becomes smaller than the output signal corresponding to the value e s1  set by the setter 3. By making the resistance value of the resistor 26 at a proper value, the output voltage of the base electric power source device becomes lower by as much as the output voltage of the pulse electric power source is changed by the regulation of the resistor 5 and the mean output voltage of the pulse arc welding electric power source device so acts as to become constant.
