  • Patent number: 11475267
    Abstract: A booster antenna for enabling ID information, code information, or the like to be reliably and easily read from an IC card or the like with a portable terminal without bringing the IC card or the like directly close to the portable terminal. The booster antenna includes: an inner coil wound twice into a circular shape; an outer coil surrounding the outer side of the inner coil and wound twice into a rectangular shape; and a terminal-side coil wound four times into a circular shape. One end of the inner and outer coils are electrically connected to each other. The diameter of the inner coil is 93% or more of the short sides of the outer coil. The booster antenna includes a connection cord connecting the other end of the inner coil and one end of the terminal-side coil and electrically connecting the other end of the outer coil and the other end of the terminal-side coil.

  • Patent number: 10106929
    Abstract: To provide a method of producing scented tissue paper. The problem is solved by performing shrink wrapping in which a tissue paper housing obtained by carrying fragrance-containing microcapsules on an inner surface of a housing box using a binder is covered with a shrink film and the shrink film is exposed to hot air W so as to be attached to the tissue paper housing, causing the fragrance-containing microcapsules to be detached from the binder by heating the tissue paper housing at the time of the shrink wrapping, and providing the scent for plural sheets of tissue papers.

  • Patent number: 9708115
    Abstract: A scented sheet member, in which a gelatin gel including at least one of a perfume and a perfume-containing microcapsule is enclosed in a space between film sheets in at least one of which a perfume-permeating hole is formed, is affixed to an inner surface of an upper surface of the containing box so that the at least one of the film sheets having the perfume-permeating hole faces a stack of paper tissues. This can provide a scented paper tissue container that can strengthen a scent when necessary.
