Abstract: A FC radiator in a FC cooling system, an EV radiator in a driving device cooling system, and a condenser in an air conditioning cooling system are arranged in one plane substantially perpendicular to a direction in which a fuel cell vehicle moves forward at a front portion of the fuel cell. Also, heat exchangers are arranged in order of the condenser, the EV radiator, and the FC radiator, that is, in order of an operating temperature from an upper position to a lower position. An angle of plural fins fitted to a front grille is changed according to a load of a fuel cell and a vehicle speed, each of the plural fins being formed to have an elongate rectangular plate shape extending in a horizontal direction.

Abstract: This optical-fiber feedthrough is constituted of a metallic sleeve 1 and an optical fiber 2 fastened thereto, and the metallic sleeve 1 is characterized by being constituted of i) a sleeve main body having a first hollow portion 9 which has an inner diameter larger than the outer diameter of the optical-fiber bare fiber uncovered portion 3 in the optical fiber 2 and into which the optical-fiber bare fiber uncovered portion is inserted, and a second hollow portion 8 which communicates with the first hollow portion and has an inner diameter larger than the outer diameter of the resin-covered portion 5 in the optical fiber and in which an inserted portion of the resin-covered portion and an optical-fiber bare fiber uncovered portion standing uncovered from the resin-covered portion to lead to the first hollow portion are held and ii) a first conical recessed portion 10 which is provided on the first hollow portion side of the sleeve main body and to which the leading end portion of the optical-fiber bare fiber u

Abstract: A spectral characteristic measuring apparatus is provided with a memory and a CPU. The memory stores a spectral profile output from a sample light sensor array when light from a lamp is received, and a plurality of spectral profiles to be output from the sensor array at each displaced position in the case where a light separator is displaced relative to a grating member of the sensor array at a certain pitch stepwise in a wavelength diffusing direction. The CPU controls the lamp to emit light in a state that a white plate for calibration is disposed as a sample, compares a spectral profile output from the sensor array for correction with each spectral profile stored in the memory, and sets a displacement amount corresponding to the spectral profile that is most approximate to the corrective spectral profile as a wavelength shift correction amount.
