摘要:
An image generating apparatus includes a position information acquiring unit that acquires position information indicating each of positions on a medium, an identification information acquiring unit that acquires identification information identifying an electronic document or the medium, the electronic document being a basis of a document image formed on the medium, an additional information acquiring unit that acquires additional information used for a user application program, and a code image generating unit that generates a code image indicating the position information acquired by the position information acquiring unit, the identification information acquired by the identification information acquiring unit, and the additional information acquired by the additional information acquiring unit.
摘要:
A composite optical fiber overhead cable having improved long-term strength and loss characteristics. A plurality of optical fibers are accommodated in spiral grooves of the spacer around which conductor strands are wound. The fibers contain flourine in at least one of the core and cladding layers thereof. Each of the optical fibers is provided with a surrounding hermetic coat, and a heat-resistant elastic material is filled between each optical fiber and the bottom of its respective groove to restrain movement of the optical fibers in the grooves in the longitudinal direction.

In a waterproof optical fiber cable for use in a communication system, one or more optical fibers are loosely put in grooves formed along a spacer and a plurality of filled portions are formed in each of said grooves by being filled with dampproof material with a predetermined interval so as to provide a plurality of filled portions and unfilled portions alternately, whereby undesired local bending of the optical fibers can be prevented. Also a method of making the waterproof optical fiber cable having such filled portions and unfilled portions is disclosed.
摘要:
An apparatus for stranding optical fiber cores while slackening the same in which optical fiber cores are pushed into core storing spaces which are to be twisted or twisted core storing spaces. A core delivering system has a passage for passing the optical fiber cores therethrough and a gas which flows from the back position of said passage towards the front position thereof functions to send out the optical fiber cores at the inlet side of said core storing spaces. The tensile forces of the optical fiber cores at the inlet sides of the core delivering system are decreased by a winding drum mechanism.

An ND filter that enables relatively easy control of light quantity when used in an iris device and realizes excellent optical performance. The ND filter has a first region having an ND film with a uniform density, a second region having an ND film with a uniform density different from the density of the first region, and a density transition region provided between the first region and the second region. The density transition region has an ND film whose density changes continuously from the density of the first region to the density of the second region.
摘要:
This invention prevents a degradation in image quality resulting from undesirable reflected light and undesirable transmitted light generated near the ridgeline of the edge portion of an optical element including an aperture blade or an ND filter. The aperture edge of the aperture blade cooperates with the aperture edge of another aperture blade to form an almost rhombic aperture. A small saw-toothed and non-periodic uneven portions having various sizes are formed along two, front and rear ridgelines of the aperture edge and along those of the ND filter. When incident light beams strike the aperture edge of the aperture blade or the edge of ND filter, the uneven portions formed at the ridgeline reflect them in various directions.
