    • An optical modulation apparatus is provided which implements a stable amplifying function by reducing the effect of reflected light rays form end faces of a bidirectional optical amplifier by imposing a numerical limitation on the relationship between the gain of the bidirectional optical amplifier and the loss of the optical modulator, or by inserting a polarization rotation section in a reflection type optical modulator including the bidirectional optical amplifier or in a multi-wavelength collective optical modulation system combining the multiple optical modulators. An optical modulation apparatus is provided which implements a stable amplifying function and cost reduction by reducing the effect of reflected light rays by interposing optical isolators at every alternate SOAs in a transmission-type optical modulation apparatus including a plurality of semiconductor optical amplifiers (SOAs) connected in a multistage fashion.

    • A spindle assembly capable of accomplishing a swing movement of a spindle bearing mechanism to a machine frame, an operation of holding bobbins on and releasing bobbins from a spindle, and an operation of actuating a rotation stopping mechanism by a sliding movement of an operation handle.In the spindle assembly according to the present invention, a first support and a second support are secured to a front end of the spindle rotatably supported at the rear end on the spindle cradle. Bobbin holding members are inserted into slits arranged on circumferential portions of the first support and the second support and moved outwardly or inwardly in the radial direction while a rear end of a sliding cylinder attached to an operation handle, which is capable of freely rotating, is inserted into an inside of the first support and engaged with projections of the bobbin holding members. Since the rear end of the sliding cylinder is formed into a conical shape, when the operation handle is drawn out, the bobbin holding members are moved inward in the radial direction, so that the bobbin can be removed from the spindle.A stop operation of the spindle is performed by engaging a frictional piece moved by rods passing through the first support and the second support by the operation handle with a conical gap of a braking cylinder secured to the spindle cradle.
    • 一种主轴组件,其能够实现主轴轴承机构向机架的摆动运动,将线轴保持在主轴上并将线筒释放的操作以及通过操作手柄的滑动来致动转动停止机构的操作。 在根据本发明的主轴组件中,第一支撑件和第二支撑件固定到主轴的后端处可旋转地支撑在心轴支架上的主轴的前端。 梭芯保持构件插入布置在第一支撑件和第二支撑件的圆周部分上的狭缝中,并且在径向方向上向外或向内移动,同时附接到能够自由旋转的操作手柄的滑动筒的后端是 插入到第一支撑件的内部并与筒管保持构件的突起接合。 由于滑动气缸的后端形成为圆锥形状,所以当拉出操作手柄时,筒管保持构件沿径向向内移动,从而能够使主轴脱开。 主轴的停止操作是通过将固定在主轴支架上的制动缸的圆锥形间隙与由操作手柄通过第一支撑件的杆和第二支撑件一起移动的摩擦片接合而进行的。
