    摘要： A diffraction grating portion (12) is formed in an optical fiber (10), having a diameter of 125 .mu.m and serving to transmit light, along its optical axis. The optical fiber is concentrically surrounded by a lower coating portion (14) having an outer diameter of 300 .mu.m and consisting of a silicone resin. The lower coating portion is concentrically surrounded by a coating portion (16) having an outer diameter of 900 .mu.m and consisting of a liquid crystal polymer, e.g., polyester amide. The coating portion is further surrounded by an outermost coating portion (18) having an outer diameter of 1 mm and consisting of a UV curing resin colored for identification. Both the optical fiber (10) and the lower coating portion (14) have positive thermal expansion coefficients. In contrast to this, the coating portion (16) consisting of the liquid crystal polymer has a negative thermal expansion coefficient.

    摘要： A mobile terminal displays a screen image provided by an image data which is produced. An in-vehicle apparatus is fixed to a vehicle or is mounted on the vehicle to be portable. The mobile terminal sends the image data to the in-vehicle apparatus through communication such that a vehicle display portion of the in-vehicle apparatus displays a screen image provided by the image data. In a case where a communication between the in-vehicle apparatus and the mobile terminal is established, when one of the mobile terminal or the in-vehicle apparatus, in which an input operation has been performed prior to the other of the mobile terminal or the in-vehicle apparatus, is in operation, only the one of the mobile terminal or the in-vehicle apparatus is operable.
