    • An image sensor capable of reading with high sensitivity at high speed, in which each light-receiving element consists of two photodiodes PD1 and PD2, which comprise a transparent substrate 1, a metal electrode 2, photoelectric transducing layers 3a and 3b, transparent electrodes 4a and 4b and an insulating layer 5, which layers are formed in superposition and patterned to provide PD1 and PD2 that are interconnected in such a way that the relationship of polarities of one photodiode is reverse to that of the other photodiode. The transparent electrode 4a of photodiode PD1 is connected to a common electrode wiring 7 (typically made of aluminum) via a contact hole 6a formed in the insulating layer 5, whereas the transparent electrode 4b of photodiode PD2 is connected to a lead wiring 8 (typically made of aluminum) via a contact hole 6b also formed in the insulating layer 5. The metal electrode 2 inter-connecting the photodiodes PD1 and PD2 is so specified in position that it is located only in an area that is capable of light reception.
    • 一种能够高灵敏度读取的图像传感器,其中每个光接收元件由包括透明基板1,金属电极2,光电转换层3a和3b的两个光电二极管PD1和PD2组成,透明电极4a 4b和绝缘层5,这些层叠加形成并图案化以提供PD1和PD2,PD1和PD2以这样的方式相互连接,使得一个光电二极管的极性与另一个光电二极管的极性相反。 光电二极管PD1的透明电极4a通过形成在绝缘层5中的接触孔6a连接到公共电极布线7(通常由铝制成),而光电二极管PD2的透明电极4b连接到引线布线8 通过也形成在绝缘层5中的接触孔6b,将光电二极管PD1和PD2相互连接的金属电极2的位置确定为仅位于能够接收光的区域。

    • An optical bus system comprising an optical bus is furnished, along two opposed edges, with a plurality of signal light input/output portions for inputting and outputting signal light to and from the bus. Any one of the signal light input/output portions on one edge of the bus inputs signal light thereto and propagates the light to the opposite edge at which another signal light input/output portion outputs the propagated signal light from the bus. The system also comprises a plurality of light emitting/receiving circuits corresponding to the signal light input/output portions. Each light emitting/receiving circuit has a signal light sending unit and a signal light receiving unit. The signal light sending unit generates signal light and sends the generated signal light into the optical bus through the corresponding signal light input/output portion. The signal light receiving unit acquires a received light signal upon receipt of the signal light output by the corresponding signal light input/output portion. At least one of the light receiving/emitting circuits on each edge of the optical bus has a repeating or reflecting part that causes the corresponding signal light sending unit to send out the signal light received by the corresponding signal light receiving unit.
    • 沿着两个相对的边缘,提供包括光学总线的光学总线系统,该多个信号光输入/输出部分用于向总线输入和输出信号光。 总线输入的一个边缘上的信号光输入/输出部分中的任何一个信号发光,并将光传播到另一信号光输入/输出部分从总线输出传播信号光的相对边缘。 该系统还包括对应于信号光输入/输出部分的多个发光/接收电路。 每个发光/接收电路具有信号光发送单元和信号光接收单元。 信号光发送单元产生信号光,并通过相应的信号光输入/输出部分将产生的信号光发送到光总线。 信号光接收单元在接收到由对应的信号光输入/输出部分输出的信号光时获取接收的光信号。 光总线的每个边缘上的光接收/发射电路中的至少一个具有使相应的信号光发送单元发出由对应的信号光接收单元接收的信号光的重复或反射部分。
