    摘要: A body motion sensor, such as an SAS diagnostic device, with which a subject can be examined in a state close to that in an ordinary living environment and it is possible to clearly discriminate between an apnea state and a hypopnea state by means of a relatively simple analytical method; and an optical fiber sheet suitable for use in the sensor. The body motion sensor, such as an SAS diagnostic device, comprises a light source such as an LED, an optical fiber sheet, and an analysis unit that determines fluctuations in the quantity of light outputted from the optical fiber sheet and detects motions of the body. As the optical fiber sheet, use is made of an optical fiber sheet comprising a planar object, such as a fabric, paper, or plastic sheet, and graded-index optical quartz fibers directly or indirectly disposed thereon or affixed thereto When the sheet is produced, it is preferred to use a pressure-sensitive adhesive sheet comprising a sheet support, such as paper or fabric, and a pressure-sensitive adhesive layer formed thereon.

The crystallized glass includes 30-70 volume % precipitation of &bgr;-spodumene solid solution or &bgr;-quartz solid solution having an average grain size not greater than 2 &mgr;m. In addition, the crystallized glass has a bend strength of 200 MPa or more and a thermal expansion coefficient of −10˜50×10−7/° C. at a temperature between −50 and 150° C.

    摘要: When plug is fitted to adapter, optical fiber is inserted to an alignment hole for the optical fiber. By providing a taper at the entrance thereof, even if the tip of the optical fiber is deviated from the central position, the deviation is absorbed to make it possible for the optical fiber to be inserted smoothly. When two plugs is fitted to adapter, the tip of one optical fiber is confronted with the other one in the alignment hole, and excessive length L.sub.1 -L.sub.2 is pushed into the two optical fiber-bending spaces with a suitable distribution, thus the optical fiber buckles therein. The end face of the optical fiber is subjected to flat surface-polishing, removal of ripples after being cleaved, or chamfer grinding after being cleaved. The buckling portion of the optical fiber is coated with carbon or the like.

    摘要: Glass material for infrared ray-transmitting optical fibers comprises a three-component material made of a 28 mol % to 38 mol % BaF.sub.2 -2 mol % to 7 mol % GdF.sub.3 -58 mol % to 69 mol % ZrF.sub.4 -based composition. The glass material is cast in a metal mold with a hollow section which is preheated to a temperature of at least 100.degree. C. but below the glass deformation temperature and annealing the melt in the metal mold to form a glass rod. The glass rod forming step includes heating the melt in the temperature range of between about 200.degree. C. and less than the glass deformation temperature and cooling the melt. The glass rod is removed from the metal mold and optically polished at the ends and sides and is then drawn into a fiber while applying tension to the tip of the glass rod while the glass rod is being heated. The glass rod is drawn into a glass fiber while maintaining the temperature at the end portion of the glass rod constant.
