  • Patent number: 10592708
    Abstract: [Problem to be Solved] Conventional devices for reproduction of holograms for appreciative viewing do not have any functionality to gate access to special content by exploiting the characteristics of the hologram. Further, a system that allows users to easily perform judgment of authenticity has been much awaited as, with holograms, although a counterfeit prevention effect can be expected visually, counterfeit imitations of the holograms themselves are already in circulation. [Means to Resolve the Problem] It is made possible to read holographic barcodes with such portable information consoles as smartphones to perform judgment of authenticity. In this process, by controlling from the portable information console side the light sources illuminating the hologram, it is possible to add a strong authenticity judgment function without a major increase in cost and also without building any special infrastructure.

  • Publication number: 20180320268
    Abstract: The aim of the present invention lies in inexpensively providing a thin-film laminated film having excellent barrier properties. A further aim of the present invention lies in providing a method for producing a thin-film laminated film in which a plurality of thin films are coated on a plastic film by means of atmospheric-pressure plasma CVD which has low equipment costs and running costs, and also in providing a thin-film laminated film production apparatus which is able to operate continuously for a long period of time and can produce high-speed coating. A thin film according to the present invention includes a plastic film, a first silicon oxide-based thin film containing silicon oxide as the main component, and a first amorphous carbon-based thin film. The first amorphous carbon-based thin film is formed on the first silicon oxide-based thin film. The first silicon oxide-based thin film has pinholes with a diameter in the range of 10-200 nm.

  • Patent number: 9915921
    Abstract: [Problem] A penlight used for decoration or as a flashlight for the purpose of illuminating the surroundings lacks functionality for optimal enjoyment of a hologram, and no conventional illumination device for a hologram has decorative effect. [Solution] The present invention has a hologram support unit, a light source, and a light diffuser, and by primarily irradiating the light diffuser from the light source, decorative effect is increased, and primarily a hologram image region can be illuminated from a predetermined angle from the same light source or a different light source. Appropriate observation is made possible by making note to an observer on a portion of a medium material integrated with a hologram material whether to irradiate illuminating light from above or irradiate illuminating light from below.

  • Patent number: 8289598
    Abstract: Recording an image of a holographic stereogram includes providing an optical deflecting device in proximity to a hologram recording medium that is exposed with a stripe-shaped elemental hologram. Either an object beam or a reference beam is deflected, in a long side direction thereof, through the optical deflecting device to expose the hologram recording medium. The hologram recording medium is multiply exposed, at least twice, with different deflection angles of the optical deflecting device to cause the stripe-shaped elemental hologram to have a plurality of parallaxes in a long side direction of the stripe-shaped elemental hologram.

  • Publication number: 20120205279
    Abstract: In an apparatus for forming a film on the inner surface of a container, a thermal catalyst is supported on a source gas supply pipe, and the source gas supply pipe is inserted into the port of the container, followed by film formation. In an apparatus for forming a film on the outer surface of a container, a thermal catalyst is arranged on the periphery of the plastic, and a source gas is blown out through the source gas supply pipe while bringing the source gas into contact with the thermal catalyst for film formation. Cooling is carried out to avoid the thermal deformation of the container by heat radiated from the thermal catalyst.
