Abstract: A light emitting component includes: a substrate; a plural light emitting elements that are provided on the substrate and respectively have light emission regions; and a plural thyristors that are turned on to cause the light emission regions of the respective light emitting elements to emit light, or that increase amounts of emitted light of the light emission regions, in which the light emitting elements absorb light emitted from a corresponding thyristor among the plural thyristors.

Abstract: A light-emitting array includes a light-emitting part having plural light-emitting block, a selection part that operates with a reference potential supplied from a reference part provided on an outside as a reference and selects the light-emitting block to be made to emit light, and a disconnection part that disconnects connection of the selection part and the reference part in a period during which a light emission current caused by low-side drive is flowing in the light-emitting block.

Abstract: A fastening structure 100 of metal plates includes a first metal plate 2 including a first hole portion 2A, a second metal plate 3 including a second hole portion 3A, and a fastening material B1 fastened to penetrate the first hole portion and the second hole portion, with the first metal plate and the second metal plate overlapping each other, wherein the first metal plate is provided with protrusions 24, 24, the second metal plate is provided with receiving portions 31A, 31B in which the protrusions fit, and with the protrusions fitting in the receiving portions, the first metal plate is restricted from rotating with respect to the second metal plate.

Abstract: An attachment member 12 of a connection direction converting connector 1a includes a frame-shaped second seal member 124 configured to seal between: a frame-shaped housing-side opposing surface 122a-6 of the attachment housing 122 that surrounds the accommodation portion that contains a connection portion between an attachment terminal 121 and a connector terminal 112 and faces the shell 123; and a frame-shaped shell-side opposing surface 123k of the shell 123 that faces the housing-side opposing surface 122a-6.

Abstract: A connector for a shielded electric wire includes: a shield terminal connected to a braid on one end side thereof and grounding the braid by contact at a leaf spring on the other end side thereof; a first packing (sealing member) that seals between a housing and an object inserted into a through hole from an inner surface of the housing to an inner surface of the through hole; and a support member that is a resin ring exteriorly mounted on the shield terminal to be adjacent to the leaf spring and disposed inside the through hole in such a manner that an outer circumferential edge thereof is in contact with the inner surface of the through hole, thereby suppressing an offset of a central axis of the shield terminal with respect to a central axis of the through hole.
