  • Patent number: 9543585
    Abstract: Provided is a binder composition for electrodes that has high stability in the form of a liquid composition dissolved or dispersed in a solvent and can improve cycle property of a non-aqueous electrolyte battery. The binder composition used is a binder composition including a polymer A containing 80% by weight or more and 99.9% by weight or less of a repeating unit derived from a monomer including a nitrile group and 0.1% by weight or more and 20% by weight or less of a repeating unit derived from an ethylenically unsaturated compound, wherein a weight-average molecular weight of the polymer A is 500,000 to 2,000,000, and a molecular weight distribution (Mw/Mn) of the polymer A is 13 or smaller.

  • Patent number: 6454608
    Abstract: The present invention relates to a connecting adapter 500 for connecting an earphone 600 with a body part 200 of a writs type of music player. In a casing 501, an earphone jack 504, and a circuit board 505 having a continuity with the earphone jack 504 are provided. A connection terminal 506 having a continuity with an earphone connector 205 of the body art 200 is provided so as to penetrate the inside and the outside of the casing 501 and have a continuity with the circuit board 505. On the outer surface of the casing 501, a fixed hook 507 for engaging with a concavity 200a of the body part 200 and a movable hook 508 for engaging with a concavity 200b of the body part 200, which is incorporated so as to be rotatable and to be biased toward the body part 200, are provided.
