Abstract: A core material (102) is contained in a cylindrical container (101) (first step). The container (101) is formed from a thermoplastic cladding material. The container (101) can be formed from a heat resistant glass such as a borosilicate glass, for example. The core material (102) is a halide having a lower melting point than the cladding material. Next, the container (101) containing the core material (102) is heated using a heater (151) and stretched, thereby forming an optical fiber emitter (105) comprising a core (103) formed from a halide crystal, and a cladding (104) formed from the cladding material.

Abstract: An illuminant has a short fluorescence lifetime, high transparency, and high light yield and a radiation detector uses the illuminant. The illuminant is appropriate for a radiation detector for detecting gamma-rays, X-rays, ?-rays, and neutron rays, and has high radiation resistance, a short fluorescence decay time and high emission intensity. The illuminant has a garnet structure using emission from the 4f5d level of Ce3+, and includes a garnet illuminant prepared by co-doping of at least one type of monovalent or divalent cation at a molar ratio of 7000 ppm or less with respect to all cations, to an illuminant having a garnet structure represented by general formula CexRE3?xM5+yO12+3y/2 (where 0.0001?x?0.3, 0?y?0.5 or 0?y??0.5, M is one type or two or more types selected from Al, Lu, Ga, and Sc, and RE is one type or two or more types selected from La, Pr, Gd, Tb, Yb, Y, and Lu).

Abstract: A differential gear set assembling method includes: a pivoting step of closing openings by guide portion and pivoting a pair of pinions between a pair of side gears; and an insertion step of inserting a pinion shaft into a pair of case shaft holes and a pair of pinion shaft holes from outside the differential case. The pivoting step is performed in a state where projecting portions are buried in the guide portions. The insertion step is performed in a state where the projecting portions are projected from the guide portions toward the pair of side gears, and the pair of side gears are pressed by the projecting portions so as to apply loads against biasing forces of coned disc springs to the pair of side gears.

Abstract: A method of producing a phenol compound comprising a step of oxidizing an aromatic aldehyde to an aryl formate and an aromatic carboxylic acid with an oxygen-containing gas, and a step of decomposing the aryl formate to the phenol compound. To facilitate the separation of the aryl formate and the unreacted aromatic aldehyde, a mixture of the aryl formate and the unreacted aromatic aldehyde is recycled to the oxidation process to concentrate the aryl formate in the oxidation mixture. Alternatively, the oxidation process is carried out in an organic solvent having substantially no ability of dissolving water to increase the conversion of the aromatic aldehyde and the selectivity of the aryl formate, thereby producing the aryl formate in a high yield.
