摘要： A fiber optical device 1A includes an amplification optical fiber 10, a seed light source 15 for supplying pulse seed light to the optical fiber 10, excitation light sources 21 to 25 for supplying excitation light, a bleaching light source 40 for supplying bleaching light for reducing a light transmission loss caused by photodarkening, and a control device 50 that controls the operations of individual portions. The control device 50 divides a period between a first output light pulse and a succeeding second output light pulse into a first period which includes a time point immediately after the output of the first output light pulse and during which the population inversion is unsaturated, and a second period which includes a time point immediately before the output of the second output light pulse, and, to the optical fiber 10, supplies the bleaching light in the first period and supplies the excitation light in the second period. Thus, it is possible to provide a fiber optical device and the method of driving it that can suitably restore the characteristics of the amplification optical fiber by photobleaching.

摘要： An automatic transmissions control system varies times to start a shift to securing a good response in engagement pressure for an engagement-side frictional element as well as suppressing occurrence of hydraulic pressure vibrations at low temperatures. The control system has an engagement pressure at-low-temperature regulation section that selectively controls at least one of the first and second engagement-pressure regulator valves, when the oil temperature is detected to be lower than a predetermined oil temperature and the shift condition is determined to exist requiring a shift operation such that the first engagement-pressure regulator valve provides a maximum hydraulic pressure to engage the first frictional element to start a shift with the maximum hydraulic pressure being continuously provided until the shift ends, and/or the second engagement-pressure regulator valve provides a minimum hydraulic pressure to obtain complete disengagement of the second frictional element to start a downshift as the shift operation.

The light transmitting member has a refractive index that achieves total reflection of a part of light entering the imaging optics system, the incident angle of the part of light is within the maximum effective incident angle of the light to the imaging optics system. The maximum effective incident angle is determined by the imaging optics system and the refractive index of an incident-side medium that is a medium provided between the imaging optics system and the optical member unit.

摘要： A Fresnel lens sheet comprises a Fresnel lens on one surface thereof, wherein respective unit surfaces constructing the Fresnel lens sheet have rough surfaces. Since it has a rough surface, it enables suppressing the occurrence of moire, when making up a screen. The other Fresnel lens sheet comprises a Fresnel lens on one surface thereof, and a fly-eye lens or prisms as a regular concavities and convexities configuration for suppressing regular reflection on the surface thereof on a side opposite to the side having the Fresnel lens formed thereon. Since it has on its rear surface a fly-eye lens or a prism, it enables suppressing the occurrence of ghost image.

摘要： In a fiber bundle (100) in which one ends of a plurality of optical fibers including cores (111a-111p), respectively, are bundled as a bundled position, the fiber bundle includes in the bundled portion a clad (112a-112p) having a refractive index less than that of each of the cores and surrounding the cores so that the cores are positioned near to each other with a minimum distance left between two adjacent ones of the cores. The minimum distance is decided so that transverse modes of laser beams propagated through the above-mentioned two adjacent ones of the cores do not affect each other. Typically, in the fiber bundle, different ends of the optical fibers are kept separated as a separated portion without being bundled. In this case, each of the cores may include a laser active material which produces, when excited by an excitation beam incident to the different end of each of the optical fibers, the laser beam propagated through each of the cores from the different end of each of the optical fibers to the one end of each of the optical fibers.
