Abstract: A surface acoustic wave device includes a piezoelectric substrate formed from a Ca3Ta(Ga1-xAlx)3Si2O14 single crystal, and an interdigital electrode formed on the surface of the piezoelectric substrate and formed from Al. The interdigital electrode is configured to generate a Love-wave-type SH wave on the surface of the piezoelectric substrate. A normalized film thickness obtained by dividing the film thickness of the interdigital electrode by the wavelength of the Love-wave-type SH wave is 0.16 or less.

Abstract: An elastic wave device that excites main vibration of an SH mode includes a piezoelectric layer formed from a piezoelectric material, a carrier substrate, and an IDT electrode formed on the piezoelectric layer. When a wavelength of an elastic wave, which is determined by an electrode cycle P of the IDT electrode, is represented by λ, the piezoelectric layer has a thickness of 0.15λ or more and 1.5λ or less. The carrier substrate has an acoustic anisotropy, and is arranged in a crystal orientation that reduces unnecessary vibrations of an SV mode and a vertical L-mode.

Abstract: Provided are an anion exchange resin being capable of producing an electrolyte membrane, a binder for forming an electrode catalyst layer and a battery electrode catalyst layer, which have improved electrical properties and chemical properties. For example, used is an anion exchange resin which has a hydrophobic unit being composed of bisphenol AF residues repeated via carbon-carbon bond and a hydrophilic unit being composed of hydrophilic groups repeated via carbon-carbon bond, in which the hydrophilic group is formed by connecting an anion exchange group to a fluorene backbone via a divalent saturated hydrocarbon group, and in which the hydrophobic unit and the hydrophilic unit are connected via carbon-carbon bond.

Abstract: Provided are an anion exchange resin being capable of producing an electrolyte membrane for a fuel cell, a binder for forming an electrode catalyst layer and a fuel cell electrode catalyst layer, which have an improved physical property (anion conductivity); a method for producing thereof; an electrolyte membrane for a fuel cell, a binder for forming an electrode catalyst layer and a fuel cell electrode catalyst layer produced from the anion exchange resin; and a fuel cell having the electrolyte membrane or the electrode catalyst layer.
For example, the anion exchange resin is obtained by reacting a hydrophobic monomer with an aminoalkyl group-containing monomer, in which the hydrophobic monomer is composed of one aromatic ring or a plurality of aromatic rings to which two halogen atoms are bonded, and the aminoalkyl group-containing monomer is composed of one aromatic ring or a plurality of aromatic rings to which two halogen atoms are bonded and an aminoalkyl group is introduced; and by quaternizing the amino group. In the anion exchange resin, a divalent hydrophobic group formed by the residue of the hydrophobic monomer, and a divalent hydrophilic group formed by the residue of the quaternized aminoalkyl group-containing monomer are bonded via direct bond.
