  • Patent number: 11036024
    Abstract: A method for manufacturing an intermittent bonding type optical fiber ribbon which is capable of forming non-connection portions and intermittent connection portions between adjacent coated optical fibers formed into an optical fiber ribbon by performing a laser processing for the ribbon through irradiation with a pulse laser light, thereby making it possible to rapidly form the intermittent connection portions and the non-connection portions while maintaining high linear velocity of the coated optical fiber. The non-connection portions and the intermittent connection portions are formed in the obtained intermittent bonding type optical fiber ribbon through the irradiation with the pulse laser light, so the intermittent bonding type optical fiber ribbon becomes the intermittent bonding type optical fiber ribbon, which is capable of securing operability during collective connection and surely being subjected to an intermediate branching without damaging cable characteristics during high density mounting.

  • Patent number: 10882783
    Abstract: An optical fiber ribbon is intermittently connected in a length direction by an intermittent connection which includes a polyol having a weight-average molecular weight of 3000 to 4000 in a specific amount relative to the entire intermittent connection and which has Young's modulus at 23° C. within a specific range. When collectively unitizing optical fiber ribbons to form an optical fiber cable, an optical fiber ribbon is formed which maintains advantages of the optical fiber ribbon and which prevents cracks of the intermittent connection and detachment of the intermittent connection from a colored optical fiber core when the cable is subjected to repetitive ironing.

  • Patent number: 10859780
    Abstract: Two bundle materials are provided on the outer periphery of a plurality of optical fibers. The bundle materials are twisted back while reversing the winding from front to back and vice versa to thus wind the bundle materials around the plurality of optical fibers. That is, the bundle materials are not wound spirally around the plurality of optical fibers. The bundle materials are bonded at a bonding portion where both bundle materials intersect. The bonding portion is provided along a center line of an optical fiber unit. The bundle materials are arranged in ranges which are each approximately 180° and partitioned by the center line.

  • Patent number: 10101549
    Abstract: Optical fiber ribbons each comprise a plurality of optical fiber strands bonded in parallel. In the optical fiber ribbons, adjacent optical fiber strands are bonded by bonding sections that are intermittently bonded at prescribed intervals. The positions of the bonding section for all optical fiber ribbons are mutually offset in the longitudinal direction. In other words, the longitudinal-direction positions of the bonding section for the optical fiber ribbons never exactly match.

  • Patent number: 10061095
    Abstract: An indoor cable is composed of an optical fiber core, tension members, an outer sheath, and so forth. The optical fiber core and the tension members are integrated by the outer sheath. The outer sheath is composed of a transparent material. The optical fiber core includes a glass wire and a resin coating (a primary resin layer and a secondary resin layer). The optical fiber core does not have a colored layer that is conventionally formed on the outer periphery of the resin coating layer. That is, the optical fiber core is composed entirely of transparent materials. On both sides of the optical fiber core, separate from the optical fiber core, is arranged a pair of tension members. The tension members are composed of transparent materials.

  • Publication number: 20170299832
    Abstract: An optical fiber cable is composed of an optical fiber core, a tension member, an outer sheath, and so forth. The optical fiber core includes a glass wire and a resin-coated part, which is further coated by a transparent member on its outer periphery. The transparent member is, for example, urethane acrylate, PVC, nylon, and so forth. The transparent member preferably has a total light transmittance, defined by JIS K7361-1, of 60% or higher. The reason is that when the total light transmittance is less than 60%, the color tone of the optical fiber core (transparent member) becomes intense and stands out. Additionally, it is preferable that the total light transmittance of the transparent member is 80% or more.

    Abstract: The reliability of a semiconductor device including a MOSFET formed over an SOI substrate is improved. A manufacturing method of the semiconductor device is simplified. A semiconductor device with n-channel MOSFETsQn formed over an SOI substrate SB includes an n+-type semiconductor region formed as a diffusion layer over an upper surface of a support substrate under a BOX film, and a contact plug CT2 electrically coupled to the n+-type semiconductor region and penetrating an element isolation region, which can control the potential of the support substrate. At a plane of the SOI substrate SB, the n-channel MOSFETsQn each extend in a first direction, and are arranged between the contact plugs CT2 formed adjacent to each other in the first direction.
