    • A print document conversion apparatus includes a plurality of software-based conversion units and a controller. The plurality of software-based conversion units perform a software-based conversion process for converting print document data described in a page description language into page image data having a bitmap image format. Each of the plurality of software-based conversion units requests a hardware-based image processing apparatus that executes specific image processing in the software-based conversion process to execute the specific image processing, and generates the page image data including a result of the image processing executed by the hardware-based image processing apparatus in response to the request. The controller activates an additional software-based conversion unit that performs the software-based conversion process when a state where at least one of the plurality of software-based conversion units waits for the hardware-based image processing apparatus to complete the image processing possibly occurs.

    • The invention provides a method for efficiently performing the alignment work of a laser diode chip with an optical fiber. A laser diode chip is faced to a coupling end face of a lensed fiber. According to algorisms stored inside an algorism storage part, X, Y and Z stages move the lensed fiber for alignment. The lensed fiber takes in laser light as it is moved in the optical axis direction (Z-axis direction) of the laser light from the laser diode chip. The lensed fiber is moved in the Z-axis direction by every movement, a half of a wavelength of the laser light, on the basis of the reference position thereof. Every time at the step moving, a light power of the laser light incident into the lensed fiber is measured. A position where the measured value becomes the maximum or a neighboring position thereof is defined as the optimum position of the optical fiber in the Z-axis direction. After rough alignment by whirl alignment, the optimum position of the optical fiber on the XY plane is determined by microalignment according to a five-point alignment method.
    • 本发明提供了一种用于有效地执行具有光纤的激光二极管芯片的对准工作的方法。 激光二极管芯片面对透镜光纤的耦合端面。 根据存储在算法存储部分中的算法,X,Y和Z级移动透镜光纤进行对准。 透镜光纤在从激光二极管芯片的激光的光轴方向(Z轴方向)移动时,摄入激光。 根据其基准位置,透镜光纤沿Z轴方向移动一半的激光波长。 每次在步进移动时,测量入射到透镜光纤中的激光的光功率。 将测定值变成最大位置或其相邻位置的位置定义为光纤在Z轴方向上的最佳位置。 在通过旋转对准进行粗略对准之后,根据五点对准方法通过微对准来确定光纤在XY平面上的最佳位置。
