A purification method for an aqueous hydrogen peroxide solution, includes passing the aqueous hydrogen peroxide solution through a first H-form strong cation exchange resin column, a salt-form strong anion exchange resin columnand a second H-form strong cation exchange resin column. An H-form strong cation exchange resin having crosslinking of 6% or less, an H-form strong cation exchange resin having crosslinking of 9% or more, or an H-form strong cation exchange resin produced by steps (a) and (b) is used as an H-form strong cation exchange resin packed in the second H-form strong cation exchange resin column: (a) copolymerizing a monovinyl aromatic monomer with a crosslinkable aromatic monomer having a non-polymerizable impurity content of 3% by weight or less therein using a predetermined amount of a specified radical polymerization initiator at a predetermined polymerization temperature to obtain a crosslinked copolymer; and (b) sulfonating the crosslinked copolymer.

Aqueous hydrogen peroxide purification method and purification system

A non-contact IC label comprising an electrically insulating first substrate; an electrically connected antenna coil and IC chip provided on one surface of said substrate; a magnetic layer provided on said one surface of said substrate so as to cover said antenna coil and said IC chip, a first adhesive layer provided on said magnetic layer, an electrically insulating second substrate provided on said first adhesive layer, a second adhesive layer provided on said second substrate, a release paper provided on said second adhesive layer, and an overlay material provided on a third adhesive layer on the other surface of said first substrate.

Noncontact IC label and method and apparatus for manufacturing the same

A non-contact type data reception and transmission body has an inlet having a base substrate, and an antenna and an integrated circuit chip which are provided on one side surface of the base substrate, and connected to each other, and a magnetic substrate layer disposed so that the magnetic substrate layer covers at least one of the antenna and the integrated circuit chip which constitute the inlet, wherein the magnetic substrate layer has a main component of a resin including a filler made of magnetic microparticles.

Noncontact data receiver/transmiter

Sheet-like audio information recording/reproducing means capable of recording/reproducing audio information is sandwiched between two support sheets from front and back only in part of the area thereof and these two support sheets are further sandwiched between two surface sheets and the support sheets and surface sheets are bonded together.
