Abstract: An identification medium is provided in which latent image having plural colors can be observed even when the identification medium is spaced away from a polarization filter. A cholesteric liquid crystal layer is provided as a specific polarization light reflection layer which reflects light having a specific polarized condition. An optical anisotropic layer having an optical anisotropy is provided at an upper position overlapping with the specific polarization light reflection layer. An image A formed by an area having an optical anisotropy different from that of surroundings is formed at the optical anisotropic layer. When the identification medium is directly viewed, the influence of the optical anisotropy cannot be seen. When the identification medium is observed via a circular polarization filter, the image can be seen to have a specific color by the influence of the optical anisotropy.

Abstract: Provided is an economical identification system suitable for use on commercial products which is difficult to duplicate, and highly identifiable. The system includes an identification medium having a high-polymer cholesteric liquid crystal material applied thereon. The high-polymer cholesteric liquid crystals selectively reflect a certain wavelength, and this wavelength changes with the change in the incident angle of the light. The liquid crystals also have the property to circularly polarize the reflected light in either sense. By taking advantages of such properties, it is possible to provide a highly identifiable structure which, however, is highly difficult to illicitly duplicate. In particular, by forming the reflective layer of a hologram with high-polymer cholesteric liquid crystals, the hologram can be used as an identification medium which is highly difficult to duplicate but easy to identify with a machine.

Abstract: A pulse generating element formed of a switchable magnetic wire is worked so as to have an arcuate shape such that the ratio R/d between the radius of curvature R and diameter d of the wire in a state free from external force ranges from 65 to 95. This is achieved by subjecting a wire of a ferromagnetic material, such as Fe--Co--V, to drawing-bending work. The pulse generating element, which is obtained by cutting the switchable magnetic wire to a predetermined length, is restricted to a substantially straight state by a retaining member, and undergoes a drastic flux reversal when it is subjected to an alternating field.

Abstract: A number of high-permeability magnetic elements are dispersed in a scanning region of a checking object. A core of a processing apparatus is provided with an exciting coil and a sensor coil. When a bias magnetic field is applied to the core, and the scanning region is passed in the vicinity of a gap, the permeability of the gap varies depending on the density of the magnetic elements, so that a magnetic flux passing through the core changes. A detection signal corresponding to the change of the magnetic flux is detected by means of the sensor coil. This detection signal is converted into a cipher code and then recorded in a code indicator section of the checking object. In checking the authenticity of the object, a detection signal obtained by scanning the scanning region by means of the processing apparatus and a code for collation obtained by decoding the cipher code recorded in the code indicator section are compared, and it is concluded that the checking object is real when the detection signal and the collation code correspond to each other.
