摘要： The present invention provides an end face polishing device capable of improving a polishing accuracy by polishing an end face of an optical fiber ferrule with adjusted polishing pressure. An end face polishing device 1 for optical fiber ferrule for polishing an end face of an optical fiber ferrule by applying a polishing pressure between a polishing plate 5 driven by a polishing drive shaft and an optical fiber ferrule held by a holding portion 9. The end face polishing device for optical fiber ferrule has: a bearing portion for allowing the polishing plate 5 to rotate relatively around the polishing drive shaft and to move relatively to the polishing drive shaft in an axial direction; a polishing plate guide supporting portion 31 for movably supporting the polishing plate 5 on a base portion 3 to apply the polishing pressure to the holding portion 9 by allowing the polishing plate 5 to move in the axial direction; a pressing drive source 15 for adjustably outputting a driving force to apply the polishing pressure; and a pressing force transmission mechanism 21 for transmitting the driving force output from the pressing drive source 15 as a pressing force in the axial movement direction of the polishing plate 5.

摘要： A resin molding is provided. The resin molding includes an optically transparent plate-shaped portion which consists essentially of a single material and which includes a first surface having a smooth surface portion, and a second surface having plural convex portions. Each of the plural convex portions includes a first inclined surface having a concavo-convex portion thereon; and a second inclined surface having a smooth surface portion. The concavo-convex portion allows at least part of light incident from the first surface to cause total reflection, diffraction and interference and to travel toward the smooth surface portion of the second inclined surface, and the smooth surface portion selectively reflects visible light in a predetermined wavelength range toward the first surface, so that when the first surface of the resin molding is observed from outside, the resin molding has a colored appearance with at least one color in addition to a metallic appearance.

摘要： A decorative plastic molded article has an outer appearance of metallic color like and a display of a character, a graph or a symbol. A body of the molded article has a plate-like portion; the plate-like portion has a first surface and a second surface; a small concave and convex portion is formed on the second surface; the small concave and convex portion has a plurality of inclined surfaces. The outer appearance of metallic color like is obtained by the total reflection light at the inclined surface and the display of a character, a graph or a symbol is obtained by the transmissive light through a planar transparent portion with shape of a character, a graph or a symbol formed in the small concave and convex portion or the total reflection light at the small concave and convex portion with shape of a character, a graph or a symbol.

摘要： In a duplex optical connector plug 10A, when one of first and second optical connector assemblies 11a, 11b is rotated around its axis in a clockwise direction or a counterclockwise direction, a rotational force of one of first and second gears is transmitted to the other of the gears by an intermediate gear. Thereby, interlockingly with the one of the optical connector assemblies 11a, 11b, the other of the optical connector assemblies 11a, 11b is rotated around its axis in the clockwise direction or the counterclockwise direction which is the same direction as the optical connector assemblies 11a, 11b.

摘要： An optical connector assembly and an optical connector adapter with a shutter each provide better heat radiation performance by blocking light outputted from a first optical fiber held by a first optical connector plug with a shutter thereby controlling temperature of an adapter body of the optical connector adapter not to exceed a prescribed level even when light having optical high power is outputted from the first optical fiber for about 15 minutes. An countermeasure against the light having optical high power is provided in a side wall of one of first and second receiving holes to be irradiated with the light outputted from the first optical fiber toward the second receiving hole and reflected thereafter by the shutter plate disposed in one of the first and second receiving holes.
