摘要： The first and second light-emitting regions are provided on the light source. When the first optical fiber having the first core diameter is connected, the light emitted from the first light-emitting region enters the first core. When the second optical fiber having a greater core diameter than the first core diameter is connected, the lights emitted from the first and second light-emitting regions enter the second core. It is thus possible to connect the optical transmission device with multiple optical fibers having different core diameters. It is thus possible to provide the optical transmission device and the communication device, which are low in cost and high in convenience.

摘要： In a device of the present invention for allowing signal light to enter a light guide body using an optical fiber, a light guide body, which is constituted by dispersing particles for scattering the signal light in an optical medium, is selected as a light guide path which requires an area where a light diffusing function is performed just after incidence of the signal light. An optical connecting material intervenes between one end of the optical fiber from which the signal light is output and opposed one end surface of a particle dispersing light guide body and a desired diffusing function is obtained.

摘要： 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.

摘要： A data receiving device includes a receiving unit, an inverse conversion unit and an error correction unit. The receiving unit receives converted data, which is obtained by converting data including transfer data of a plurality of bits, and an error detection code for error detection of the transfer data, according to a predetermined first procedure. The inverse conversion unit inversely converts the received converted data according to a predetermined second procedure. If it is impossible for the inverse conversion unit to inversely convert the converted data, if it is possible for the inverse conversion unit to inversely convert inverted data obtained by inverting a portion of the bits of the converted data, and if an error is not detected in data obtained by inversely converting the inverted data based on the error detection code, the error correction unit performs error correction by inversely converting the inverted data.

摘要： A bearing stiffness of a sintered metal sleeve is prevented from lowering. A sleeve includes an inner section formed of metal powder for sintering and a resin for impregnation, and a surface deformation section which covers a surface of the inner section and is formed by shot blast process. Since the surface deformation section is formed by the shot blast process, the number of pores formed between the metal powder for sintering near the surface can be reduced. In this way, a supporting pressure at a bearing portion can be prevented from being released out through the pores, and the bearing stiffness can be prevented from lowering.

摘要： A semi-transmissive type liquid-crystal display device suppresses the reduction and corrosion of the transmission or common electrode due to the cell corrosion reaction with a simple method. In each pixel region, the reflection electrode is formed over the glass plate, where the interlayer insulating film and the barrier metal film intervene between them. The reflection electrode is electrically connected to the transmission electrode by way of the barrier metal film. The transmission electrode and the corresponding scanning line thereto are apart from each other at a distance of 2 μm (preferably, 3 μm) or greater. A developer solution penetrating through the crack formed in the barrier metal film does not reach the transmission electrode (or common electrode), preventing the reduction and corrosion of the transmission or common electrode.
