Abstract:
The present invention relates to a safety shield for protecting a passenger in an internal space from external physical dangers caused by the occurrence of a disaster, wherein the safety shield comprises an outer appearance unit. The outer appearance unit is made of a material that can shield from and absorb the physical danger. The safety shield can be folded and stored under ordinary circumstances, and the volume of the safety shield can be inflated by air fed in from an air tank upon the occurrence of a disaster so as to form the internal space.
Abstract:
A water surface floating body with light reflective material excelling in durability, being free from the trouble of maintenance, and being able to maintain its reflective capability over long periods of time is provided. This water surface floating body is a water surface floating body such as an oil transport hose, oil fence, anti- pollution dispersing film and the like floated on the surface of water even at night. A light reflective material comprising glass beads having a metal vapor-deposited film provided thereon is attached to the outer surface of the floating body.
Abstract:
A horseshoe life buoy (16) comprises an air tight and waterproof shell (1,2,3) of flexible plastics material and means (9, 10, 15) for automatically inflating the shell for launch in a man overboard situation. Optionally, the life buoy is provided contained, deflated and folded or rolled, in a two piece container (13), the container (13) being mountable in a fixed bracket (14) and optionally, the means (9, 10, 15) for automatically inflating the shell comprises a static line (15) which is fixed to the bracket (14).
Abstract:
Three respective reflectors, which comprise a widthwise reflector composed of two half plates facing each other with a rotating support shaft therebetween, a lengthwise reflector composed of two half plates facing each other with the rotating support shaft therebetween, and a bottom reflector arranged centrally of the rotating support shaft, are made perpendicular to one another at diametrical positions thereof, and an inclined support hole is provided in the rotating support shaft to incline a "detection design angle". It is possible to stably keep the "detection design angle" in use, readily provide a configuration required for use in the event of an emergency, and to store the respective reflectors when not in use such that they can be stacked flat one upon another free from bulkiness.
Abstract:
Three reflector plates comprising: a lateral reflector plate having two half plates each opposingly placed across a rotation supporting shaft introduced therebetween, a longitudinal reflector plate having two half plates each opposingly placed across the rotation supporting shaft therebetween, and a bottom reflector plate placed at the central portion of the rotation supporting shaft, wherein these three reflector plates are brought into mutual orthogonal intersection at their diameters, and the rotation supporting shaft is provided with an inclination supporting hole with an inclination of a "detection design angle", thereby enabling to maintain the detection design angle when in use and enabling to easily assemble into the shape for use even in case of emergency, and further enabling the reflector plates to be stacked flat one upon another and stored free from bulkiness when not in use.
Abstract:
Un ballon gonflable (50) et des composants de signalisation (56, 58, 60, 62) fixés au ballon sont stockés à l'intérieur d'un organe de fermeture (22) maintenu assemblé par un boîtier séparable (20, 24, 26) permettant de renfermer un dispositif de gonflage (36) du ballon. L'enlèvement de l'organe de fermeture déclenche le gonflage du ballon, le fonctionnement des composants de signalisation, et la séparation du boîtier séparable, permettant le positionnement du dispositif de gonflage pour le lancement aérien du ballon auquel sont suspendus les composants de signalisation.
Abstract:
PURPOSE: A shaping method of a reflector for reducing a reflected signal of a radar is provided to reduce an RCS(Radar Cross Section) and multiple reflection from a vessel. CONSTITUTION: The patterning method of the reflector for the radar reflective signal reduction is as follows. A flat element plate(110) is consecutively arranged in order to form a reflecting plate. The flat element board slopes about a horizontal plane as the predetermined angle. The direction of the reflected wave of the radar signal is controlled with the reflecting plate and prevents the single reflection and the strong multiple reflection.
Abstract:
PURPOSE: A deception ship to enhance the susceptibility of naval vessels is provided to protect core combat vessels from attack of enemy and secure the balance of power in combat against stronger enemy. CONSTITUTION: A deception ship to enhance the susceptibility of naval vessels comprises a radar reflector(1), plastic bags(2), a hot air generator(3), and a noise generator(4). The radar reflector has a multi-hedral shape and reflectance similar to a protection target. The plastic bags of large box shape are arranged on a small boat(7). The hot air generator fills hot air in the plastic bags so that the deception ship can simulate infrared signals of the protection target using the hot air.
