  • Patent number: 7803455
    Abstract: The present invention provides an optical element including: a substrate; and an antireflection film formed on a surface of the substrate. The antireflection film includes a plurality of lower refractive index layers, and a plurality of higher refractive index layers which are layered alternately. Each of at least two of the plurality of lower refractive index layers comprises a same main component each other and comprises a side component with a different content ratio independently.

  • Patent number: 7665924
    Abstract: On the one surface of a back plate suited to a length-and-width size of a ring binder, hooks serving as an engaging means are formed. The back plate is fixed to the spine surface of the file cover. When the ring binder is pressed against the back plate, the hooks are engaged with the ring binder so that the file cover is mounted on a booklet bound with the ring binder.
