    摘要: A simple-structure, small-size, inexpensive optical isolator mounted in an amplifier. The PMD and PDL are reduced to desired numerical levels to improve the characteristics. The optical isolator is composed of two double refraction elements, a 45 DEG Faraday rotator, a magnet, a lens, and a total reflection member. The directions of crystal axes of the two double refraction elements and the direction of the rotation of the Faraday rotator are appropriately set. Therefore, going-returning optical paths where incident unpolarized light is separated into ordinary light and extraordinary light, totally reflected by a total reflection member, and outputted are formed. The direction of the crystal axis with respect to the direction of the normal on the element surface of either of the two double refraction elements and the thickness in the direction of the normal on the element surface are corrected.

    摘要: A polarization-independent optical isolator having a structure in which polarization dispersion is virtually eliminated by selecting the thickness and optical axis orientations of birefringent crystalline plates used in the isolator. The optical isolator of the present invention employs a combination of birefringent crystalline plates wherein the optical axis orientation of at least one birefringent crystalline plate in the optical isolator is different from the optical axis orientation of the remaining birefringent crystalline plates, and the polarization mode dispersion, which is induced when the beam propagates through the birefringent crystalline plate having a different optical axis orientation, is equal to the dispersion rate of the polarization mode dispersion attributable to the remaining birefringent crystalline plates and in a mutually inverse direction.

    摘要: Transgenic plants that are modified to produce fruits that have altered levels of soluble solids compared to non-transgenic species of the same species are provided. The transgenic plants are modified by introduction of DNA constructs that encode invertase operatively linked to DNA encoding regulatory regions that direct transcription of the DNA encoding invertase and to DNA encoding sequences that direct proper processing of the invertase through the secretory pathways of the plant and targeting of the invertase to the vacuole.In particular, DNA constructs encoding tomato plant vacuolar invertase in operative linkage with a developmentally regulated promoter region are provided. Preferred regulatory and structural DNA is obtained from genomic DNA clones and cDNA clones encoding tomato fruit vacuolar invertases from the commercial tomato plant, Lycopersicon esculentum, and wild tomato plant, Lycopersicon pimpinellifolium.Probes derived from the genomic DNA and cDNA, antibodies specific for tomato fruit invertase, and uses therefore, are also provided.

    摘要: The tip of a first optical fiber 8 is fused integrally to a second optical fiber 7, having a single refractive index and an identical outer diameter, which has a spherical lens 10 with the length and diameter to produce a beam expansion by Gaussian diffusion to at least 80 .mu.m or greater at the exit and a radius of curvature greater than 200 .mu.m. The spherical part of the second fiber is formed by thermal fusion; a spherical lens having the desired diameter at the optical fiber tip is formed by feeding the optical fiber tip into a thermal fusion unit to form the spherical lens. An optical fiber terminal for optical coupling composed of a single mode optical fiber, a non-doped silica fiber beam expansion segment, and a non-doped silica spherical lens, is connected to a polarization-independent optical isolator. A ferrule support having a rotatable spherical segment formed at the tip, in which the second optical fiber and an optical fiber protecting material are inserted and stabilized in a through-hole of the ferrule support, and a coupling unit consisting of a flange and a cap, which contact with the spherical surface of the spherical segment at opposite sides after the ferrule support has been adjusted into a position which produces an optimal beam converging function.

    摘要: A method of producing a forged part includes holding a material by a jig, upsetting the material, held by the jig, to a predetermined length by a pair of upsetting dies disposed on both ends of the material, while pressing the upsetting dies on the material, so as to produce large-diameter portions at the respective axial ends of the material. Next, a bending operation and a forging operation are made to the upset material, in that order. When forging, a direction, in which the material is forged, is set, so that a burr generated on the material by upsetting is included in a burr generated on the material by forging. Next, a finish-machining operation is made to the forged material to remove the burr left on the outer periphery of the material after forging. Thereafter, the finish-machined material is drilled to form bush-mounting holes in the large-diameter portions.
