  • Patent number: 11965801
    Abstract: A measurement system includes a measurement device including a light source, and a first power meter, and one or a plurality of connection members each configured to optically connect a pair of optical fiber lines of the plurality of optical fiber lines. A first optical fiber line of the pair of optical fiber lines includes a first end and a second end, a second optical fiber line of the pair of optical fiber lines includes a third end and a fourth end, the one or plurality of connection members optically connect the second end to the fourth end, the light source causes testing light to be incident on the first end, and the first power meter measures first intensity of first output light output from the third end by causing the testing light to propagate through the pair of optical fiber lines.

  • Publication number: 20100261834
    Abstract: A shape memory rubber molded article (1) obtained from a mixture containing a rubber and a crystalline non-polymeric compound. The rubber in the molded article is crosslinked. A deformed state of the shape memory rubber molded article (1) is fixed by crystallizing the non-polymeric compound, and the fixed deformed state is released by melting the non-polymeric compound. The non-polymeric compound is preferably a wax. The shape memory rubber molded article (1) preferably contains a crosslinking agent. In the molded article (1), the rubber and the non-polymeric compound are preferably in finely divided separate phases.

  • Patent number: 6791501
    Abstract: The present invention includes an antenna rod, an antenna base which attaches the antenna rod so as to be capable of swiveling, a joint assembly which consists of a cylindrical member in an axial direction orthogonal to an axial direction of the rod at one end of the antenna rod, a pair of pivotal support portions provided so as to confront an upper portion of the antenna base so as to mount the joint assembly on a pivot in a swiveling manner, and a torsion spring which is provided with respect to the joint assembly and automatically returns the joint assembly to a predetermined swiveling position by giving the elasticity of itself even if a swiveling position of the joint assembly is changed due to an external force applied to the antenna rod.
