  • Patent number: 8033843
    Abstract: A pivoting lever has tongue-like movable pieces formed in a squared U-shape on both side faces of a cover member, and locking claws at intermediate parts of the movable piece. A pivoting lever is pivotally supported on a support pin of the cover member. Circular arc-shaped cam grooves are formed in a lever body part, and locking holes engaging locking claws are formed in the lever body part. When a mating housing is pressed into a housing and the lever is pivoted, the cam grooves drive a driven pin and pull the mating housing toward the housing. The lever contacts the locking claws, and pivots the locking claws while pushing them down. When the housings are joined, the locking claws returned to the original positions fitted into the locking holes, setting the lever to a locked state, thereby disabling further rotation and reverse rotation of the lever.

  • Patent number: 8014645
    Abstract: A 1.55 ?m band dispersion shifted optical fiber is provided which has a low loss and low dispersion slope. A core region “a” is heavily doped with GeO2 . A core region “b” is composed of pure SiO2 glass. A cladding section is arranged around the core region. The cladding section has a lot of holes extending in the longitudinal direction of the optical fiber. The holes of the cladding section are not located at random, but have a honeycomb structure composed of regular hexagons which have a side length of ?, and serve as a primitive lattice. The center of the core section has a region having a refractive index higher than that of the periphery of the core section. The core section has the refractive index distribution in which the group velocity dispersion at the operation wavelength of the region becomes the normal dispersion.
