Abstract: This invention relates to an anti-counterfeit printed matter, including securities such as banknotes, stock certificates, and bonds, various kinds of certificates, and important documents, which requires anti-counterfeit or anti-copy. [Solving Means] A visible image is formed by a first object group arrayed in a first direction at a predetermined pitch and a second object group arranged in the non-imaging area of the first object group. The second object group forms the negative and positive images of a first invisible image by arbitrarily arranging two kinds of objects in pairs in the on/off relationship. Addition, in the anti-counterfeit printed matter, the first object group includes object portions that are formed in at least two height levels from the surface of the printed matter so as to have a predetermined difference in height, thereby forming a second invisible image.

Abstract: Provided is a communication device for measuring a usable bandwidth without delay in transmission of primary data. The relay device according to an embodiment of the present invention, when measuring a usable bandwidth in communication with another relay device, processes a user packet including a user data to be transmitted to the other relay device so as to be changed into a specific packet size while the user data is maintained as it is, and utilizes it as a measurement packet. Accordingly, even though it is a measurement packet for performing measurement of a bandwidth, since it includes user data, it may be treated in the same manner as a user packet thereby enabling an efficient use of a communication network in communication. Also, even though UDP is used, since a usable bandwidth can be measured, it is possible to measure a bandwidth even though streaming data is distributed while preventing any influences on the distribution.

Abstract: A magnetic resolver includes a stator core made of magnetic material, coils, and a rotor. The stator core has a base plate and protrusions formed integrally with the base plate so as to protrude from a surface of the base plate in the thickness direction. The coils are provided around the respective protrusions. The rotor is disposed so as to face the surface of the base plate with the coils interposed therebetween. The overlapping area between the rotor and each of the protrusions changes with a change in a rotation angle of the rotor relative to the stator core. The stator core has through-holes that pass through the base plate and the respective protrusions in the thickness direction.

Abstract: Encrypted communications are performed between private networks over a wide-area network (e.g., the Internet) by way of routers, each of which includes a management table for storing entries including identifiers and control parameters. Uplink control connections are established between routers so as to mutually communicate and update stored contents of management tables therebetween. Updated stored contents of management tables are subjected to publication to other routers. Alternatively, stored contents of management tables are periodically subjected to publication to other routers. Thus, it is possible for operations managers to reduce manual operations for setting up control parameters in management tables of routers.
