    摘要: A polarization-maintaining photonic crystal fiber 10 includes six thin holes 4a and 4b adjacent to a core 1. Among these holes 4a and 4b, a pair of holes 4b at opposite sides of the core 1 have a diameter greater than that of the other four thin holes 4a, and therefore, the polarization-maintaining photonic crystal fiber 10 has polarization-maintaining ability. An overclad layer 3 exists around the clad layer 2 which includes a large number of thin holes 4a and 4b around the core 1. The overclad layer 3 includes a pair of marking portions 5 at opposite sides of the core 1. The marking portions 5 are holes which can be seen at positions different from the clad layer 2 when the fiber 10 is viewed from a position right above the fiber 10 in the drawing. In this way, the direction of the polarization plane of the polarization-maintaining photonic crystal fiber 10 is identified.

    摘要: An information recording and/or reproducing apparatus for recording and/or reproducing information in or from a card information recording medium with a recording and/or reproducing head, includes a carriage on which the medium is to be mounted, a carrying device for carrying the medium onto the carriage while keeping in contact with the medium, and a moving device for moving the carriage relative to the head. The carrying device is arranged to be free contact with the medium after the medium has been carried onto the carriage. The carrying device is a semicircular rubber roller, and a surface of a flat part of the rubber roller is placed in a state opposed to a surface of the medium after the medium has been carried onto the carriage, whereby the rubber roller is freed from contact with the medium.

    摘要: This invention relates to a temporary ink storage member for temporarily storing ink in accordance with pressure changes in an ink tank. The temporary ink storage member comprises a reduced thickness portion forming an ink storage portion and having a comb-toothed longitudinal sectional shape and slit-like ink grooves communicating with the ink storage portion, wherein a plurality of ink grooves are formed symmetrically with one another in cross-section. The present invention relates also to a writing instrument using the temporary ink storage member.
