Abstract: A method for manufacturing a light guide plate, such as a sign or guide display board, that guides light incoming from a side surface of a substrate thereof and guides the light outgoing from a major surface thereof. The method includes arranging fabrication dots in a matrix shape at a rectangular distal surface of a ultrasonic fabrication horn, forming, on a major surface of the light guide plate substrate, reflection dots corresponding to the fabrication dots on the distal surface upon pressing the distal surface of the ultrasonic fabrication horn to the major surface of the light guide plate substrate, and forming the reflection dots in a prescribed range on the major surface of the light guide plate substrate by repeating formation of the reflection dot upon correlative movement of the ultrasonic fabrication horn within the major surface with respect to the light guide plate substrate.

Abstract: The present invention reduces generation of unevenness on a surface by adjusting unevenness of a reflection pattern in a case where the reflection pattern is formed by an ultrasonic process.

Abstract: A roof apparatus for a vehicle, includes a pair of guide rails, a movable panel, a housing, a casing, and a first spur tooth rack belt and a second spur tooth rack belt for transmitting a drive force of a drive mechanism to the movable panel. The first spur tooth rack belt includes plural first spur teeth and the second spur tooth rack belt includes plural second spur teeth, and a slope portion inclined upward toward a rear side of the vehicle is provided forward of each of the pair of guide rails. A pair of guide portions is provided at each of the guide rails for guiding the first spur tooth rack belt and the second spur tooth rack belt. A cutout portion is formed at a front end portion of each of the guide rails.

Abstract: A roof opening/closing apparatus includes a roof moved between first and second positions and structured with first, second and third panels, a first supporting mechanism movably supporting the first and second panels in association with each other, a second supporting mechanism movably supporting the third panel, a first lock mechanism locking the first panel to the vehicle body, a second lock mechanism locking the first supporting mechanism, and a third lock mechanism locking the third panel to the second panel. The roof is moved between the first position and the second position by the first and second supporting mechanisms and retained at the first position by the first to third lock mechanisms. The second and third lock mechanisms are connected to each other by an operational member and operated in association with each other to release locking operations thereof by the operational member.
