摘要： PROBLEM TO BE SOLVED: To provide a safe and simple lifeline-throwing appliance contrived in view of the fact that most of the existing lifeline-throwing guns used in life-saving activities are dangerous, and they are under legal regulations, so it is almost impossible for fire fighters or similar carriers to carry the appliance with them, or dispose it beforehand in a place where such a danger is expected. SOLUTION: The above problems are resolved by employing the following means. (1) The appliance is characterized by having a pressurized energy in a tank as a principal power source. In this appliance, a so-called PET-bottle is originally improved, whose safety as airframe is conventionally acknowledged. (2) Further, the appliance is characterized by using a launcher, which has a form to be carried by an operator himself in its main part and a cover almost enclosing the airframe.

摘要： PROBLEM TO BE SOLVED: To enable a flow to be easily visualized to facilitate knowing a pattern of the flow by making bubbles exist and collapse in liquid and depositing or generating a substance which can be identified from outside in the liquid. SOLUTION: When bubbles 2 collapse in liquid, a part of substances constituting the liquid is altered so that a substance 4 which can be identified from outside such as a smoke-like substance, a granular substance, a powder substance or their assembly is deposited or generated in the liquid. That is, electromagnetic energy such as electric power, optic energy such as laser light, kinematic energy such as ultrasonic waves or vibration, hydrodynamic energy such as a velocity head or thermodynamic energy such as a calorific value which is supplied from outside the liquid is utilized. By making the bubbles 2 exist and collapse in the liquid, the substance 4 which can be identified from outside is deposited or generated in the liquid, thereby visualizing a flow 1.

摘要： PROBLEM TO BE SOLVED: To develop a ventilating system which eliminates dangers of accidents due to penetration of exhaust gas through an air supply opening or the like, which are increased in houses of high airtightness or the like, such as an accident that 'a person using a gas water heater died from gas poisoning, since the exhaust gas is penetrated indoors through a ventilating fan'. SOLUTION: Problems are solved by 'using means 'to lessen the rate of the gas flowing out from an exhaust opening which is contained in the gas flowing into an air supply opening', such as 'disposing a projection from a wall surface''. The present device has the projection 2 from the wall surface as the means to lessen the rate of the gas flowing out from the exhaust opening 5 which is contained in the gas flowing into the air supply opening 6. The rate of the gas flowing out from the exhaust opening which is contained in the gas flowing into the air supply opening is made small relatively and the gas can be used for ventilation.

摘要： PROBLEM TO BE SOLVED: To obtain a simple and effective tracer generating method and apparatus for visualizing the flow of liquid such as petroleum. SOLUTION: An apparatus which visualizes stream line or streak line is manufactured based on the fact that some liquid precipitates or generates smoke type material or the like, which is recognizable from outside, by electric discharge caused inside of the liquid. The apparatus comprises three sets of electrodes 4 provided at intervals of 0.1mm in petroleum, and means for causing electric discharge by continuously applying a direct-current voltage of about 2000V to these electrodes 4. Thus, the occurrence of smoke type material or the like 3, stream line and streak line are clearly observed by using the apparatus.
