摘要： According to the present invention, an optical switch apparatus is provided for switching the connections between a plurality of fixed optical fibers which are fixed and arranged on an optical fiber support base within a container filled with an index-of-refraction matching agent, and movable optical fibers provided on a movable base which is moved by a moving mechanism comprising a worm gear within the aforementioned container. In addition, a worm gear driving member and a cam driving member of a matching device are both provided on the exterior of the aforementioned container via a seal. This worm gear driving member which is connected to a control device, starts the positioning sequence and moves the movable base to a standby position following return of the movable base to a predetermined origin within the container. As a result, it is possible to prevent contamination of the index-of-refraction matching agent over a long period of time, and thereby reduce the connection loss to a satisfactory level. In addition, since the driving precision of the movable base is also improved, it is possible to achieve superior effects such as reduction of the array pitch of the fixed optical fibers, improvement of the precision and increase in the multiplicity of the optical switch apparatus.
摘要翻译：根据本发明，提供一种光开关装置，用于切换多个固定光纤之间的连接，固定光纤被固定并布置在填充有折射率匹配剂的容器内的光纤支撑基座上，并且可移动设置在由上述容器内的由蜗轮构成的移动机构移动的可动基座上的光纤。此外，蜗杆传动构件和匹配装置的凸轮驱动构件均经由密封件设置在上述容器的外部。连接到控制装置的该蜗轮传动构件开始定位顺序，并且在可移动底座返回到容器内的预定原点之前将可动基座移动到待机位置。结果，可以防止长时间的折射率匹配剂的污染，从而将连接损失降低到令人满意的水平。此外，由于可移动基座的驱动精度也提高，所以可以实现降低固定光纤的阵列间距，提高精度和提高光开关装置的多重性等优异的效果。

摘要： An optical connector ferrule has an optical fiber containing hole reaching from the rear end surface near the end surface and a fine pore extending from the optical fiber accommodating hole to the end surface to be connected. A bare fiber of a polarization-maintaining optical fiber is inserted into the fine pore. Since the length of the fine pore is short, the influence of the uniformness of the adhesive in the fine pore is smaller, and therefore the stress distribution is maintained, resulting in stabilizing the polarization characteristics. A flange unit is attached to the ferrule after an optical fiber is inserted to the ferrule and fixed. Therefore the optical fiber is easily adjusted with respect to the housing in the circumferential direction around the axis, and optical fibers are connected by but joining with high accuracy.
摘要翻译：光连接器套圈具有从靠近端面的后端面到达的光纤容纳孔和从光纤容纳孔延伸到要连接的端面的细孔。将偏光保持光纤的裸光纤插入细孔中。由于细孔的长度短，粘合剂在细孔中的均匀性的影响较小，因此保持应力分布，从而稳定极化特性。在将光纤插入套圈并固定之后，法兰单元附接到套圈。因此，光纤相对于壳体在周向上容易地绕轴线进行调节，并且光纤以高精度连接而是接合。

摘要： Two-stage skew adjustment is achieved by first using only the drive force of the platen roller with the pinch roller and the capstan roller drive disrupted by a gap opening mechanism to effect a large skew adjustment. Then, the gap is closed and the platen roller, which has a Teflon-resin coating thereon and a larger diameter than the capstan roller or pinch roller, effects a small skew adjustment. Thereafter, printing is effected by feeding the paper in a reverse direction to register with an inked ribbon feed of a primary ribbon using the platen roller drive and the pinch roller drive with the skew cycle repeated for each ribbon color segment to achieve improved multicolor printing registration.

摘要： An optical connector that provides a housing body 21 and a fixed part 22 that are installed so as to hold a backplane 3, and connects an optical connector plug 4b inserted into said housing body 21 via an installation hole in said backplane 3 and another optical connector plug 4a inserted into said housing body 21 from the direction opposite to that of said optical connector plug 4b, wherein flexible claws 25 projecting from both sides of said fixed part 22 engage said housing body 21 via said installation hole 30 in said backplane 3, and thereby said backplane 3 is held between said housing body 21 and said fixed part 22. Simply by adjusting the floating range (amount of floating) of the flexible claws 25 within said installation hole 30 the floating range (amount of floating) of the housing body 21 can be reliably set. Thereby, when the housing body 2 engages the printed board housing, the dimensional error is offset reliably by the floating of the housing body 21, and the engagement is carried out smoothly. A special order part for setting the floating range of the housing body 21 is not necessary, and thus a lower cost is possible and assembly can be carried out easily. In addition, a structure can also be used wherein the flexible claws projecting from the housing body side engage the backplane by passing through the installation hole, and the backplane is held between the bearing walls on the side of the housing body.

摘要： A ventilating window for ventilating the interior of a building or a structure such as a vehicle in a natural and gentle manner. A ventilating window for the exhaust of air is provided with a mechanism for automatically opening a window casement when the atmospheric pressure inside the window is higher than the outside atmospheric pressure, thereby dispensing with forced exhaust using a fan or the like. A ventilating window for the supply of air is provided with a mechanism for automatically closing a window casement when the atmospheric pressure outside the window is higher than the inside atmospheric pressure, thereby preventing a strong wind from blowing into the interior. A ventilating window for both exhaust and supply of air is provided with both such opening mechanism and closing mechanism.
