Abstract: The aim is to provide a novel compound that can luminesce with high brightness and be used as a luminescent substrate in a firefly bioluminescence system. Provided is a heterocyclic compound, or salt thereof, represented by the following general formula (1): [R1, R2, and R3 are independently hydrogen or an alkyl group having a carbon number of 1-4, with provisos that R1 and R2 are optionally bonded to form a ring and that one of R1 and R2 is optionally bonded to Y1 to form a ring; X is S, O, NR4, or CH2, and Y1 and Y2 are independently N or CR4, where each R4 is independently hydrogen, an alkyl group having a carbon number of 1-4, an alkenyl group having a carbon number of 2-4, or an acyl group having a carbon number of 2-4; n is an integer of 0-4].

Abstract: A hinge assembly for a vehicle closure panel includes a body mounting member configured to mount the hinge assembly to a vehicle body, a closure panel mounting member configured to mount the hinge assembly to the vehicle closure panel and a hinge connecting arm pivotally connected by a first pivotal connection at a first end to the body mounting member and pivotally connected by a second pivotal connection at a second end to the closure panel mounting member. A first fastening member is movably received by the closure panel mounting member. A first stop member limits movement of the first fastening member in a first direction toward the closure panel mounting member. A second stop member limits movement of the first fastening member in a second direction away from the closure panel mounting member.

Abstract: A vehicle width direction wall portion (29) and a front-rear direction wall portion (33) are formed in a stiffener (7) provided inside a front door (1), the vehicle width direction wall portion (29) extending in a vehicle width direction, the front-rear direction wall portion (33) extending from a vehicle width direction inner end (31) of the vehicle width direction wall portion (29) in a vehicle front-rear direction. Additionally, a locking member (23) is provided on the front-rear direction wall portion (33) at a portion, and faces a lock lever (25). The locking member engages the lock lever, after a load is inputted to an outside handle and a door outer panel thereby deforming the door outer panel, to prevent movement of the lock lever after the deforming the door outer panel.
