    摘要: In an optical transmitter comprising a directly modulated laser and a wavelength filter provided on a post-stage of the directly modulated laser, the wavelength filter has a modulated light input port for inputting modulated light output from the directly modulated laser, a filter transmitted light output port for outputting light having a wavelength included in a filter transmission band among the modulated light as filter transmitted light, and a filter cutoff light output port provided separately from the modulated light input port and the filter transmitted light output port and outputting light having a wavelength included in a filter cutoff band among the modulated light as filter cutoff light, and the peak of the filter transmission band is set on a shorter-wave side from the peak of the spectrum of modulated light output from the directly modulated laser.

    摘要: The present invention provides sealing device which is capable of a two-step holding operation with the use of a linear solenoid. The sealing device includes a stopping mechanism for stopping a movement of a movable part that forms the linear solenoid when the linear solenoid is driven at a predetermined midway point between a start point and an end point after the nozzle part has been moved from the waiting position to the stop position, and for releasing the movable part from a stop to allow the movable part to move again and reach the end point after the nozzle part has been returned from the stop position to the waiting position.
