  • Patent number: 11390356
    Abstract: An electric connector device for a human-powered vehicle comprises a connector base and a coupling structure. The connector base includes a first connection port and a second connection port. The first connection port defines a first center axis. The second connection port defines a second center axis. The second center axis is spaced apart from the first center axis as viewed in a predetermined direction. The coupling structure is configured to detachably attach the connector base to an additional device so that the connector base is non-movably attached to the additional device. The coupling structure is provided between the first center axis and the second center axis as viewed in the predetermined direction.

  • Publication number: 20220206198
    Abstract: A light-absorbing composition according to the present invention includes: a light absorber; a curable resin; and an alkoxysilane. The alkoxysilane includes a dialkoxysilane. Since the alkoxysilane of the light-absorbing composition includes the dialkoxysilane, desired flexibility is likely to be imparted to a light-absorbing layer owing to an organic functional group of the dialkoxysilane while a strong skeleton having a siloxane bond is formed in the light-absorbing layer.

  • Patent number: 10969577
    Abstract: An optical scanning device includes a reflector that is pivotable, a light-emitter that emits a detection light toward the reflector, a detector that receives the detection light reflected at the reflector, and a light-blocking unit that includes a slit wherethrough the detection light passes. The light-blocking unit is disposed on an optical path whereby the detection light reflected from the reflector advances to the detector. The slit has an aspect ratio where a length of the slit in a direction in which the optical path extends relative to a length of the slit in a width direction is equal to or greater than a predetermined value. The width direction is along a pivoting direction of the reflector, of an opening end portion of the slit. The detector is configured to detect a pivot angle of the reflector by receiving the detection light that passes through the slit.
