摘要： PURPOSE:To improve the extent of safety in preventing a lump of snow from falling off by covering the surface of a steel tower constituent member, consisting of a steel pipe or the like, with a sheetlike reticular member via a spacer, and holding the snow lain on the surface with this reticular member. CONSTITUTION:A cover member 7 consisting of a sheetlike reticular member 8 is attached to the surface of a power-transmission steel tower constituent member 2 being composed of a steel pipe 1 and angle steel or the like in keeping a specified clearance via a spacer 4. In succession, snow lain on the surface is kept up with the cover member 7, and the snow is made so as not to fall off even if it is frozen, while the frozen snow is kept up until the spring thaw. With this constitution, any damage due to falling snow is thus preventable.

摘要： PURPOSE:To obtain an electric cable excellent in wind noise and AN characteristics by composing the outermost strand layer of thick and thin strands having nearly sectorial sections, forming a groove part at nearly the central position on the surface of each large diametral step and specifying their characteristics and shapes. CONSTITUTION:The outermost strand layer of a stranded wire is composed of thick strands 1 and thin strands 2 both having nearly sectorial sections and smooth step surfaces are spirally formed on the peripheral surface of the stranded wire by the difference between strands 1, 2, and also a groove part 11 is formed at nearly the central position on the surface of each large diametral step. Hereupon, where a center angle being formed with actual surfaces of each surface 10a of the large diametral step is thetae, an uneven level difference is h, an equivalent outside diameter of a surface- smooth electric cable to an ordinary electric cable is de, an outside diameter of the ordinary electric cable is d, a depth of a recess being formed between the strands adjoining each other which form a surface 10b of a small diametral step is delta and an opening width of the recess is t, expressions I to VI are satisfied. In this way, the electric cable of low wind noise and low AN having a constitution for attaining the optimum condition in both low wind noise and AN properties can be obtained.

摘要： PURPOSE:To improve the wind noise characteristic and the AN(audible noise) characteristic by forming a recessed section prepared under a specified condition at about the central position of a surface of large diameter stepped surface. CONSTITUTION:The bottom part of a recessed section 11 is designated by determining a virtual concentric circle Q relative to an electric cable wherein each of interposed element-wires 3, 3 is inscribed, expressing an intersecting point where the virtual concentric circle intersects the side surfaces of thick-walled element-wires 1, 1 on both sides of the circle respectively as D, D' and equalizing the length delta of this D-D' to the width of the bottom part while equalizing also a difference in radial direction between the virtual concentric circle Q and a circle P of large diameter difference in level to the depth (ho) of the recessed section. Furthermore, a central angel which the side surface of the recessed section forms to the center of the electric cable is expressed as thetao and a central angle which a plane between actual surfaces A, A' of a large diameter stepped part forms as thetae. Values of these expressed signs must be determined to satisfy the condition of a formula I. The electric cable can thus reduce not only wind noises as well as wind pressure but also audible noises originating in corona generated waterdrops in case of a rainfall.

摘要： PROBLEM TO BE SOLVED: To respond to non-lighting and the like of a different type of flight obstacle light. SOLUTION: The flight obstacle light status notification device includes: a means for measuring waveforms of a current and a voltage supplied to a flight obstacle light to calculate effective power; a comparison means for comparing the effective power with a threshold value; and a notification means for notifying a predetermined notification destination of a status according to a predetermined relationship when the effective power and the threshold value have the predetermined relationship. Thus, by calculating the effective power, the status of the flight obstacle light (for instance, non-lighting of one light or the like) can be appropriately detected even for a bulb type flight obstacle light or a neon tube type flight obstacle light. Since it is not necessary to introduce a specific sensor detecting non-lighting, cost can be reduced as well. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PURPOSE:To provide an instrument for measuring water content of snow which has a simple structure and can be readily automated. CONSTITUTION:An instrument for measuring water content of snow measures the water content of snow in such a way that snow is made to fall into a container 4 maintained at 0 deg.C by opening the door 5 of the container 4 and the door 5 is closed after snow 17 lies on a transparent plate 6, and then, a reflection type infrared sensor 7 measures the water content of the snow 17 by irradiating the lower surface of the snow 17 with infrared rays from the bottom of the plate 6 and receiving reflected light. The level of the received reflected light is recorded in a recording section 3. Since the snow 17 is laid on the plate 6 and reflected light is received while the lower surface of the snow 17 is irradiated with infrared rays beyond the distance equal to the thickness of the plate 6, the ruggedness of the infrared ray irradiating and reflecting surface of the snow 17 can be eliminated and the surface is completely made flat. Therefore, the water content of the snow 17 can be accurately measured, because the influence of the variation of detecting distance on the sensor output can be eliminated.
