Abstract:
본 발명에 따른 다수 채널을 갖는 광가이드 장치는 광을 투과하는 투명한 몸체; 와, 상기 몸체에 소정 간격을 두고 복수의 1차원 배열로 형성된 채널 집광부;로 이루어지되, 채널 집광부는 소정 간격을 두고 복수 개 1차원 배열로 상기 몸체에 형성되어 전면으로 입사되는 광을 분할하여 집속하고 재차 시준하거나 또는 입사하는 광을 독립적으로 시준하는 단위 광학모듈; 과 상기 단위 광학모듈과 일대일 대응되어 상기 몸체에 형성되고 단위 광학모듈로부터 광을 입사 받아 좌우측면, 전후측면 또는 상하 특정위치에 광을 집광하도록 광의 독립적인 경로(광채널)를 형성하는 광채널모듈로 이루어져, 입사되는 광을 더욱 짧은 거리로 가이드 하여 광 에너지 이용효율을 극대화할 수 있고, 구조가 간단하여 제작과 설치가 용이하며, 평판 형이어서 얇고 부피가 크지 않고, 제조비용도 저렴한 효과를 얻을 수 있다.
Abstract:
PURPOSE: An electronic stopper apparatus is provided to stop or rotate one member of a planetary gear train, thereby reducing noise and rotation frictional heat. CONSTITUTION: A pickup module includes a pickup member (311), a pickup spring (312) and a rotor (313). The pickup member and the rotor are connected through the pickup spring. A stopper module includes a stopper body (321), a bobbin (322) of which an inner periphery is hollow, a stopper shaft, a pickup support member, a stopper (325) and a metal friction member. The stopper body includes a body case (3211), a ferrite or metal core ring (3212). The bobbin including the ferrite or metal core ring and a magnet wire is settled inside the stopper body.

PURPOSE: An improved device for adjusting a distance between slats and a blind using the same are provided to allow the same to occupy a minimum volume, and to quickly and freely adjust the distance. CONSTITUTION: An improved device for adjusting a distance between slats includes a slat supporting body, a rotary shaft, a worm gear (92j), and a distance adjusting unit. The slat supporting body supports each slat of a blind. The rotary shaft is automatically and manually rotated by power or a control unit. The worm gear linearly moves along the axial direction of the rotary shaft, and slides. The worm gear rotates together with the rotary shaft, and is in directly and indirectly contact with the slat supporting body. The distance adjusting unit is coupled with the worm gear, and the whole or the end portion of the distance adjusting unit is moved by the rotation of the worm gear along the rotating axial direction of the worm gear.
Abstract:
The present invention provides a two-way clutch assembly for a rotor operating device which is safe and quiet, does not use a lubricant to increase durability, is applicable regardless of various loads, and does not use a wrap spring. The two-way clutch assembly includes a two-way driver (710) having a two-way movement groove which is formed on the inner circumferential surface of a body and has a small diameter part (710c) and a large diameter part (710d); a wheel retainer (720) which has resilient member holders (720a) radially arranged on a body and is connected to an operating member to be able to rotate; a roller member (730) inserted between the two-way movement groove of the two-way driver (710) and the unit resilient member holders (720a) of the wheel retainer (720) to be able to rotate; and an insertion member which is connected with the wheel retainer (720) via a bushing and selectively gets in contact with the roller member (730) or is released from the contact with the roller member. In the case that the two-way driver (710) is not rotated through the wheel retainer (720) but tries to rotate autonomously, the roller member (730) gets in contact with the insertion body and is rotated and connected with the insertion body while being pressed by the small diameter part (710c). When the wheel retainer (720) is operated, the roller member (730) which is locked by the resilient member holders (720a) is revolved and is resiliently supported, and then, pushes the small diameter part (710c) of the two-way movement groove of the two-way driver (710) in the rotating direction of the wheel retainer (720) in order to rotate the two-way driver (710).
