  • Publication number: 20240085764
    Abstract: An electronic apparatus includes a plurality of contacts electrically connectable to an accessory and arranged in a first direction orthogonal to a direction in which the accessory is attached. The contacts include an attachment detection contact to detect an attachment of the accessory to the electronic apparatus, and a communication request contact for a communication request from the accessory to the electronic apparatus. The attachment detection and communication request contacts are disposed between a contact closest one end and a contact closest to another end in the first direction. The attachment detection contact is disposed between the communication request contact and the contact closest to the one end. In the first direction, a distance between the attachment detection contact and the communication request contact is shorter than that between the communication request contact and the contact closest to the other end.

  • Publication number: 20220088678
    Abstract: In order to provide a method for producing silver nanowires in which a local maximum of optical absorption in the plasmon absorption band can be shifted toward the short wavelength side without making the wire diameter smaller, a method for producing silver nanowires includes a step of heating a mixed liquid of a dispersion of silver nanowires and metal ions of a transition metal that is different from silver, and reducing the metal ions, thereby intermittently precipitating clumps of the transition metal on a surface of the silver nanowires. The thus produced silver nanowires have metal clumps intermittently along the length direction, and a local maximum of optical absorption in the plasmon absorption band of the silver nanowires has been shifted toward the short wavelength side.
