摘要： PROBLEM TO BE SOLVED: To easily find out a position of a grip of a door even if lighting is turned off and to make it possible to smoothly open and close the door. SOLUTION: In a grip 10 mounted to a door 30, a fluorescent member 20 formed by mixing a light storing fluorescent body with a light permeable resin or glass is so mounted to a specific part of the grip 10 that the surface of the fluorescent member 20 is exposed to the surface of the grip 10. As the light storing fluorescent body, it is a compound indicated as MAl2 O4 , M is the compound constituted of at least one or more metal elements selected from a group of calcium, strontium and barium (or compound constituted of a plurality of metal elements adding magnesium to the metal elements concerned) as mother crystal, europium as activator, and the light storing fluorescent body adding rare earth elements are coactivator is used.

摘要： PROBLEM TO BE SOLVED: To provide a telephone box snow-melting device capable of melting snow on the outside ground of the door of a telephone box, keeping the inside heating, simplifying construction of the device with a low construction cost as well as a low maintenance cost. SOLUTION: A plate heater 100 is laid on the ground located at just under the part projected from an opening and closing door 13 to the outside of a telephone box 10 when the opening and closing door 13 is opened. At the same time, a plate heater 100-2 is also laid on the ground located at just under the inside of the telephone box 10. The plate heaters 100 and 100-2 are plate bodies having specific thickness with a large number of approximately cone-shaped holes on the upper and lower surfaces, and the holes on both up and down surfaces are equipped with a honeycomb structural body having construction alternately arranged so as to have one side wall for common use, the honeycomb structural body is directly laminated to the upper surface or the lower surface or both surfaces of a plate-like heater or indirectly through another member, and they are formed together as a unit.

摘要： PROBLEM TO BE SOLVED: To provide a freeze preventing structure which can prevent occurrence of a traffic accident due to different road surface condition between a bridge and roads on opposite sides thereof, and which has a simple structure, having a high strength and a high degree of thermal efficiency. SOLUTION: A preheater is composed of a honeycomb structure in which several conical holes are formed in the upper and lower surfaces of a panel having a predetermined thickness, these holes are alternately arranged so as to commonly use one side wall, and a plate-like heater an upper and/or lower surface of which is laminated with the honeycomb structure in directly through another member. Several preheaters 100 are laid in the road surface of a bridge 200 and the road surfaces on the ground on opposite sides of the bridge, and are connected thereto with a power source for heating. With this arrangement, freeze or snow covering on the load surface on the bridge 200 can be effectively prevented.
