Abstract: A latch mechanism opening and closing detection system for accurately detecting the open and closed state of a door including a claw configured to be pushed by a striker and rotated in a fastening direction; a pawl member configured to contact the claw and rotate in an interlocked manner such that the claw engages at a half-lock point corresponding to a middle portion of a rotation range of the claw and at a full-lock point corresponding to an end portion of the rotation range, thereby limiting rotation of the claw in an unfastening direction; and a full-lock detection switch configured not to be manipulated at the half-lock point and configured to be switching-manipulated at the full-lock point by the claw and the pawl member, thereby detecting a state in which the claw is fully fastened to the striker.

Abstract: A laminated glass antenna structure includes: a lower glass sheet including a first surface facing inside and a second surface at the upper end thereof; an upper glass sheet including a third surface adjacent to the lower glass sheet; an adhesive film positioned between the upper glass sheet and the lower glass sheet; and an antenna unit including a plurality of microstrip patch unit cells provided on the second surface and the third surface with respect to a ground plane provided on the first surface.

Abstract: The present invention provides a spring washer for a turbocharger including a stopper part formed at an inner periphery there and a line contact part formed at an outer periphery thereof, thus to prevent a spring repulsive force from being exerted thereto more than necessary even when exerting excessive compression and continuous compression force from peripheral parts, and prevent an inclination bent section from being flattened, thereby maintaining or improving restoring characteristics of the inclination bent section. The ring-shaped spring washer installed in a bypass valve of a turbocharger includes: an inner periphery having a stopper part fixed to a lower surface thereof with being overlapped therewith; an inclination bent section integrally formed with the inner periphery with being inclined downward; and an outer periphery having a line contact part integrally formed with the inclination bent section to be in line contact with a support of the spring washer.
