Abstract: PURPOSE:To prevent the coloration of a core material and heighten the transparency of the core material and make the material switably usable in decorative fields, etc., by using transparent solid polymer as the core material wherein the polymer is obtained by polymerization of monomer containing a specified amount of a polymerization inhibiting agent. CONSTITUTION:Regarding a light transmitting tube composed of a hollow tubular transparent clad material and a transparent core material having refractive index higher than that of the clad material, a transparent solid polymer obtained by polymerization of monomer containing 2ppm or less polymerization inhibiting agent is used as the core material. In that case, more preferably polymer obtained by polymerization of monomer containing 2ppm or less, desirably 0.5ppm or less, polymerization inhibiting agent is used for the core material by employing distillation refining method, absorption refining method by silica gel, activated carbon, molecular sieve, etc., ion exchange refining method, chromatographic refining method, purifying method by an alkaline solution, etc.

Abstract: PURPOSE:To operate illumination of a large area with one piece of light source by projecting and emitting the light from a light source supplied via a light transmission hose with a planar or curved surface light emitting surface and further a large area region. CONSTITUTION:This surface light emitting device comprises the light source 1, the light transmission hose 2 and a light emitting member 3 and is used on the roof of a building 4, etc. The light source 1 emits light of a specific color (wavelength) and the light transmission hose 2 is formed by packing a viscous liquid-like core into a high-polymer clad worked to a flexible pipe shape. Both ends of the clad are closed by transparent windows. The light is totally reflected at the boundary of the core and the clad and the incident light is transmitted to the other end by using the clad having the refractive index lower than the refractive index of the core. The light emitting member 3 is mounted to the advertisement 5 and the light rays of the respective colors supplied from the light transmission hose 2 progress in the core. These light rays partly transmit the inside of the clad without totally reflecting on a part of the inside peripheral surface The right rays are thus efficiently emitted from the outer peripheral surface.

Abstract: PURPOSE:To easily and quickly confirm desired area and destination by making a line shape light emitting means emit or flash light in a specific color. CONSTITUTION:The line shape light emitting means 3 emits or flashes the light sent from a light source 1 via a light transmission hose 2 in line shape from a station entry to a platform along the path of a station, etc., and four diffused light tubes 3A-3D are used at every line of each system. The diffused light tubes 3A-3D are formed with cores made of the same transparent material as that of the light transmission hose 2, and of transparent material with refractive index lower than that of the core. In the diffused light tube 3, the light sent from the light transmission tube 2 advances the core, and total reflection occurs on an inner peripheral surface, however, no total reflection of the light on another inner peripheral part occurs, and the light passes the inside of a clad, and it can be efficiently emitted from an outer peripheral surface to the outside. Also, the light is shielded by mounting an opaque casing on half periphral surface through which no light transmits out of the outer peripheral surfaces of the clad.

Abstract: PURPOSE:To obtain high safety optimum for illumination in a dangerous area easy to generate induced explosion by fire, etc., by supplying light from a light source provided at a place separated from the dangerous area to the dangerous area via a light transmission hose. CONSTITUTION:An incandescent lamp, for example, is used as the lamp adaptive for the one for the illumination of a warehouse 4, and it is housed in a lamp house 1A outside the warehouse 4. The light transmission hose 2 is formed in such a way that a core in viscous liquid shape is filled in a polymer clad worked in flexible pipe shape and both terminals of the clad are sealed with a transparent window. As the clad, the one with refractive index lower than that of the core is used. A light emitting means is to perform the illumination of the warehouse 4 by diffusing the light transmitted on the light transmission hose 2, and a light diffusing tube 3 is used as the means. The light sent out from the light transmission hose 2 advances the core of the light diffusing tube 3 and no total reflection of a part of the light occurs on an inner peripheral plane, and it transmits the clad, then, it is emitted from an outer peripheral plane to the outside with high efficiency.

Abstract: PURPOSE:To freely illuminate the corner part of a room and an external desired part, etc., and to reduce power consumption by performing illumination with minimum one lamp by providing an illumination means which emits and diffuses light transmitted to a light transmission hose in line shape. CONSTITUTION:The light transmission hose 2 is formed in such a way that a core in viscous liquid shape is filled in a macromolecule clad worked in flexible pipe shape and both terminals of the clad are sealed with a transparent window. As the clad, the one with refractive index lower than that of the core is used. The illumination means 3 is formed so as to emit light of specific color sent from a light source 1 via the light transmission hose 2 almost uniformly in line shape, and a light diffusing tube 3 is used in the means. The light sent out from the light transmission hose 2 advances the core of the light diffusing tube 3 and total reflection occurs on an inner peripheral plane on one side. however, no total reflection of a part of the light occurs on the inner peripheral plane on the other side, and it transmits the clad and is emitted to the outside with high efficiency.

Abstract: PURPOSE:To provide a highly safe sterilizing device in water capable of economically sterilizing without a fear of polluting environment. CONSTITUTION:Ultraviolet ray is used for a sterilizing and disinfecting means, i.e., the ultraviolet ray is conducted to water in a pool 4 or the like to be sterilized and irradiated from an irradiating pipe 3 in water to sterilize and disinfect the water. Any fear of polluting environment is not generated even if the steri-lization and disinfection by the ultraviolet rays are repeated many times.

Abstract: PURPOSE:To improve the external force detection sensitivity and prevent the rupture and plastic deformation of an optical wave guide and the dissociation of light transmitting and light receiving means from the optical wave guide by constituting the optical wave guide with a translucent core made of specific elastic material and a clad. CONSTITUTION:An optical wave guide 1 is constituted of a solid core 4 with high light permeability and made of a rubber elastic material with high refraction factor and a clad 5 made of a rubber elastic material with the refraction factor smaller than that of the core 4, and the core 4 is formed with a material selected among the synthetic rubber such as chloroprene rubber, urethane rubber, silicone rubber, fluororubber, acrylic rubber, ethylene propylene rubber, ethylene propylene copolymer and epichlorohydrin rubber. The light wave guide 1 can be thereby elastically deformed softly and largely in any direction, the open circuit and elastic deformation of the light wave guide 1 and the dissociation of light transmitting and light receiving means 2 and 3 from the light wave guide 1 can be prevented, thus the presence and size of the action of the external force can be detected with excellent sensitivity.
