    摘要： The present invention relates to a waveguide photodetector having a good efficiency of coupling with an optical fiber or a PLC (Planar Light-wave Circuit). In order to increase size of mode beam and to effectively receive light from the optical fiber or the PLC, a thin absorbing layer is used as a core and a semiconductor having an index of refraction similar to that of the absorbing layer is used as a cladding layer. By doing so, it is possible to obtain a good efficiency of coupling with an optical fiber or a PLC. In addition, since a little amount of light proceeds along a waveguide, it is possible to obtain high operating speed even under a high power. Furthermore, by reducing difference between indexes of refraction of the absorbing layer and the cladding layer, it is possible to suppress the “carrier-trapping” generated from small difference between band gaps of the two materials.

    摘要翻译： 本发明涉及一种具有与光纤或PLC（平面光波电路）耦合的良好效率的波导光电检测器。 为了增加模式光束的尺寸并且有效地接收来自光纤或PLC的光，使用薄的吸收层作为芯，并且将具有类似于吸收层的折射率的半导体用作包层 层。 通过这样做，可以获得与光纤或PLC耦合的良好效率。 此外，由于沿着波导进行少量的光，所以即使在高功率下也可以获得高的运行速度。 此外，通过减少吸收层和包层的折射率之间的差异，可以抑制由两种材料的带隙之间的小差异产生的“载流子捕获”。

    摘要： An apparatus for connecting and disconnecting a developing bias power supply in an image forming system. A plurality of developers are operated in sequence to develop an electrostatic latent image formed on a photosensitive body in a predetermined color. An electro-magnetic clutch, which corresponds to each of the developers, connects and disconnects driving of each of the developers. A deceleration gear assembly is rotated according to a rotation of a gear of the developer connected to the electro-magnetic clutch. A connection unit, which is driven by the deceleration gear assembly, rotates and connects/disconnects the developing bias power supply to/from each of the developers.
