摘要： Disclosed herein is a reliable laminated optical element that is a hybrid optical element obtained by laminating an optical resin layer on an optical substrate such as a glass substrate, the optical resin layer being less likely to be separated from the optical substrate even under high temperature and high humidity conditions.The laminated optical element comprises an optical substrate 1 made of an optical material, an intermediate layer 2 provided on the optical substrate 1, and an optical resin layer 3 provided on the intermediate layer 2. The optical resin layer 3 is made of a resin composed of an organometallic polymer having an -M-O-M- bond (M is a metal atom), a metal alkoxide and/or a hydrolysate thereof having only one hydrolyzable group, and an organic polymer having a urethane bond and a methacryloxy group or an acryloxy group. The intermediate layer 2 is obtained by dispersing metal oxide microparticles in a matrix resin composed of a metal alkoxide having a radical polymerizable group and a hydrolyzable group and/or a hydrolysate thereof.

摘要： A semiconductor laser device comprises a cladding layer of a first conductivity type, an active layer, a cladding layer of a second conductivity type, and a current blocking layer having a stripe-shaped opening having a predetermined width W for restricting a current path and forming the current path, and having a larger band gap than that of the cladding layer of the second conductivity type and having a smaller refractive index than that of the cladding layer of the second conductivity type. A difference .DELTA.n between effective refractive indexes in a region, which corresponds to the opening, in the active layer and an effective refractive index in a region, which corresponds to both sides of the opening, in the active layer and the width W (.mu.m) of the opening are so set as to satisfy a predetermined relationship. The difference .DELTA.n between the effective refractive indexes is set by selecting the A1 composition ratio of the current blocking layer and the thickness of the cladding layer of the second conductivity type on the both sides of the opening.

摘要： A weft picking system for an air jet loom is provided with a microcomputer as a controller. The weft picking system comprises a weft traction device including a pair of rollers, one of which is driven by an inverter motor. A weft yarn fed from a weft measuring and storing device can be placed between the rollers to be drawn toward a weft posture regulating nozzle. The weft posture regulating nozzle is arranged to project the weft yarn into the shed of warp yarns and regulates the posture of the weft yarn under the influence of air jet ejected from the nozzle and from a plurality of sub-nozzles. The rollers always rotate during a weaving operation of the loom. A change-over device is provided to change the weft yarn from a first state of being placed between the rollers to a second state of separating from the rollers or vice versa. A weft yarn slackened portion is unavoidably formed between the weft traction device and the weft posture regulating nozzle, due to a temporary difference in the tractive speed between the weft posture regulating nozzle and the weft traction device. A slackened portion deforming device is disposed between the weft traction device and the weft posture regulating nozzle to effectively deform the slackened portion in a manner to smoothen the slackened portion enough as to prevent any trouble in the weaving operation and any defects in the woven fabric.

摘要翻译： 用于喷气织机的纬纱拾取系统设置有作为控制器的微型计算机。 纬纱拾取系统包括一个包括一对辊的纬纱牵引装置，其中一个由逆变器马达驱动。 从纬纱测量和存储装置输送的纬纱可以放置在辊之间，以朝着纬纱姿势调节喷嘴拉伸。 纬纱姿势调节喷嘴布置成将纬纱投射到经纱梭口中，并且在喷嘴和从多个副喷嘴喷射的空气喷射的影响下调节纬纱的姿态。 滚筒总是在织机的织造操作期间旋转。 提供转换装置以将纬纱从放置在辊之间的第一状态改变到与辊分离的第二状态，反之亦然。 由于纬纱姿势调节喷嘴和纬纱牵引装置之间的牵引速度的暂时差异，纬纱牵引装置和纬纱姿势调节喷嘴之间不可避免地形成纬纱松弛部分。 在纬纱牵引装置和纬纱姿势调节喷嘴之间设置有松弛部分变形装置，以有效地使松弛部分变形，以使松弛部分平滑，足以防止织造操作中的任何麻烦和机织织物中的任何缺陷。
