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.

A polarization-maintaining optical fiber and absolutely single-polarization optical fiber are provided which enable long distance transmission maintaining a polarization state of signal light. The polarization-maintaining optical fiber includes a core, photonic crystal cladding, and jacket. The photonic crystal cladding is divided into four segments by broken lines from the center to the periphery. Among a plurality of grating holes in a pair of segments opposed to each other with respect to the core, the diameter of grating holes close to the core is greater than the diameter of grating holes in another pair of segments opposed with each other, and than a grating constant.

An unprocessed substrate is conveyed to a film-processing chamber at the same time a processed substrate is conveyed to a substrate preparation chamber, reducing the substrate processing cycle, thereby increasing the yield per unit time. The substrate preparation chamber has a two-tiered structure for receiving processed substrates and unprocessed substrates. A two-tiered transfer robot allows the substrates to be removed or placed into the preparation and process chambers at the same time, thus decreasing the cycle time for processing a substrate.

Disclosed is a method of disposal of metallic aluminum-containing solid waste comprising the steps of reacting radioactive solid waste containing metallic aluminum with an alkali solution to generate a hydrogen gas and then mixing the resulting reaction liquid with a solidifying material containing a latent hydraulic material as a main component to solidify the liquid. According to the method of the invention, solidification of aluminum-containing radioactive solid waste in a highly filled state (high concentration) is feasible and a solid having excellent mechanical strength and properties of preventing oozing of radioactive nuclide can be obtained.

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.
