Abstract: An optical connector cleaning tool includes a cylindrical connecting portion to which an optical connector is connected, a cleaning unit configured to guide a cleaning thread to a coupling end face of an optical connector plug, and an optical unit having an optical path reaching the optical connector plug. The optical unit includes a lens arranged in a position facing the coupling end face to form one end portion of an optical system, and having a missing portion extending in an optical-axis direction, and an image sensor positioned at the other end of the optical system. The cleaning unit includes a rod-like cleaning tip having a thread passage through which the cleaning thread passes. The cleaning tip is inserted into a hollow portion of the lens having the missing portion extending in the optical-axis direction, such that the cleaning tip is movable in a longitudinal direction thereof.

Abstract: An optical connector cleaning tool includes a cleaning tool main body, a feed-side bobbin, a cleaning head (cleaning portion), a winding-side bobbin, a moving body that moves at the time of cleaning, a feed mechanism that sends an unused cleaning medium in synchronism with the moving body, and a winding mechanism that drives the winding-side bobbin. The feed mechanism moves a turn-back portion at one point where the cleaning medium is turned back in a direction to separate from the winding-side bobbin. The winding mechanism includes a driving piece that engages with a rotation body of the winding-side bobbin. The driving piece slips with respect to the rotation body when a load to press engaging projections of the rotation body has reached a predetermined load.

Abstract: A polishing method and a polishing film are provided for automatically performing multi-stage batch polishing on an end surface of a workpiece. An end surface of a workpiece and a polishing plate are moved relative to each other while bringing the end surface of the workpiece into contact with a polishing film of the polishing plate. The end surface is moved in a circular motion with a diameter 2 R relative to the polishing film; the center of the circular motion is moved linearly by a distance S on the polishing film; the polishing film is provided with first, second, and third polishing surfaces; and the polishing film is further provided with cleaning surfaces between the polishing surfaces so that the range of the distance S in which one rotation in the circular motion crosses over different polishing surfaces is reduced, or does not cross over different polishing surfaces.

Abstract: An optical connector cleaner comprising a supply reel, a take-up reel, a case, an operation lever, a take-up mechanism, and a holding member. The supply reel stores a cleaning cloth member having one end side wounded thereon. The take-up reel takes up the other end side of the cleaning cloth member. The case has a connector connection portion on which the cleaning cloth member is exposed. The operation lever that has an operation portion projecting from the case and is swingably supported. The take-up mechanism rotates the take-up reel in a take-up direction by a predetermined angle when the operation lever swings. The holding member holds an optical connector on the connector connection portion in a state in which a coupling face of the optical connector is pressed against the cleaning cloth member exposed to the connector connection portion.

Abstract: A water-repellent coating has tetrafluoroethylene resin powder, silicone resin binder, and organic solvent. The tetrafluoroethylene resin powder has a ratio of the peak absorbance at 1,800 cmnull1 to the peak absorbance at 500 cm null1 of 0.0001 to 0.05 exclusive. A coating film is formed by applying such a coating on a substrate. The coating has the properties of high water repellency, excellent anti-ice-coating, excellent anti-snow-coating, and so on, in spite of not having a large amount of fluororesin powder. In addition, the coating of film keeps the water repellency regardless of whether the coating film is immersed into water for a long time.
