Abstract:
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.
Abstract:
In an image deforming method and an image deforming apparatus, a portion of an input image is geometrically deformed to be outputted therefrom. Input and output image buffers keep input and output image data items, respectively. An image deforming method and a partial deformation region are specified in an image deformation specification unit. For each pixel of the output image, a before-deformation coordinate value calculating section calculates coordinate values thereof before the deformation. A shift calculating section calculates a coordinate shift amount expressing a quantity of shift for each pixel of the output image between coordinate values of the pixel and those of the pixel before the deformation, and the coordinate shift amount is stored in a pixel reallocation map storage in the form of a pixel reallocation map. While reallocating pixels in accordance with the shift amount in the storage, a partial pixel deforming unit transfers values of the pixels from the input image buffer to the output image buffer.

Abstract:
An integrated circuit device includes a substrate, circuit elements on the substrate, and an electrically conductive thermoplastic resin substance electrically connecting the circuit elements on the substrate. Therefore, since variations in the configuration of the thermoplastic resin are quite small relative to those of interconnecting wires, variation in parasitic inductance due to variation in the configuration of the connections is reduced and the uniformity and the reproducibility of the high frequency characteristics of the integrated circuit device are enhanced. A method for fabricating an integrated circuit device includes forming circuit elements on a substrate and forming an electrically conducting thermoplastic resin substance electrically connecting the circuit elements.

Abstract:
The present invention is to provide a method for identifying an optical line easily and accurately regardless of the optical line length. A plurality of reflecting parts is placed on the optical line, and a combination of relative positions of the reflecting parts is changed for every optical line to form an identification code, and the relative positions of the reflecting parts are detected based on reflected lights when a detecting light is inputted to the optical line, so that the optical line is identified based on a result. Concretely, when the detecting light is inputted to one end of the optical line, the light is reflected at the plurality of the reflecting parts which form the identification code and comes back the input end. A combination of the relative positions etc. of the reflecting parts is changed for every optical line. To detect the relative positions of the reflecting parts which form the identification code, either the optical path difference of the reflected lights from the reflecting parts is measured or the time difference between the reflected lights come back from the reflecting parts is measured. Then, based on the result, the optical line can be identified.
