摘要： An optical connector cleaning tool includes a supply reel (11) having a belt-like cleaning cloth (3), and a winding bobbin (12) for winding the cleaning cloth (3). The optical connector cleaning tool also includes a housing (7) which rotatably supports the supply reel (11) and winding bobbin (12), a cleaning head (13) which comes in contact with the cleaning cloth (3), and a pressing member (5) which supports the cleaning head (13) and moves in a longitudinal direction with respect to the housing (7). The optical connector cleaning tool further includes a slide spring (53) which biases the pressing member (5) forward, and a transmission mechanism (33) which transmits an action of the pressing member (5) to the winding bobbin (12). The transmission mechanism (33) includes a rack (32) on the side of the pressing member (5), and a pinion on the side of the winding bobbin (12). When the pressing member (5) retreats with respect to the housing (7), the transmission mechanism (33) rotates the winding bobbin (12) in a winding direction so as to feed the cleaning cloth (3). This optical connector cleaning tool can easily clean an optical connector plug while achieving downsizing by using a simple structure.

摘要： A person to be authenticated generates authentication data for this time and authentication data for next time using a one-way function, based on a user ID, a password and a random number, and performs an exclusive OR operation on these, to thereby encrypt the data while associating the both parameters with each other, and transmits these data together with the own user ID to an authenticating person. The authenticating person receives the aforesaid three informations, compares a validity confirmation parameter calculated by using a one-way function based on the authentication data for this time with a authentication parameter registered in the previous authentication phase, and when these parameters agree with each other, judges that authentication is approved, and registers the authentication data for next time as the authentication parameter for next time.

摘要： A conversion adapter to be used for connecting opposed optical connector ferrules having different diameters is formed of an amorphous alloy possessing at least a glass transition region, preferably a glass transition region of not less than 30K in temperature width. Particularly, the amorphous alloy of M1-M2 system or M1-M2-La system (M1: Zr and/or Hf, M2: Ni, Cu, Fe, Co, Mn, Nb, Ti, V, Cr, Zn, Al, and/or Ga, La: rare earth element) possesses a wide range of nullTx and thus can be advantageously used as a material for the conversion adapter. Such a conversion adapter can be manufactured with high mass-productivity by a mold casting method or molding method.

摘要： An image processing device includes a search scenario acquisition unit and a search unit. The search scenario acquisition unit acquires a search scenario in which one or more search processes of searching for an image using an image feature based on a target image, which is an image of a search target, in a search condition are combined. The search unit searches for a matching image, which is an image to be searched, using a combination of the search processes represented by the search scenario and outputs search result information representing an area in the matching image detected through the search.

摘要： An optical connector cleaning tool includes a cleaning head that faces the lens (cleaning target portion) of an optical connector, and a cleaning cloth (3) that moves with respect to the cleaning head in a state in which the cleaning cloth is in contact with the lens. The cleaning cloth (3) is formed into a strip shape by a fabric (25) including a plurality of warps (28) in which a longitudinal direction thereof is a moving direction of the cleaning cloth moving with respect to the cleaning head. The warp (28) includes a first chemical fiber (31) and a second chemical fiber (32). One chemical fiber of the first chemical fiber (31) and the second chemical fiber (32) is in a stretched state, and the other chemical fiber is in a slack state. It is possible to provide an optical connector cleaning tool capable of cleaning a lens-type optical connector.
