The apparatus includes a transmitter emitting a sensor beam passing through the space transversely to advancing direction for being intermittently interrupted by the sliver during displacement thereof transversely to the advancing direction; and a receiver positioned in a path of the sensor beam for receiving a light or a dark signal dependent whether or not the sensor beam is interrupted by the sliver during displacement thereof transversely to the advancing direction.

Abstract: A reflecting-mirror-type variable optical attenuator based on a new principle is provided. A reflecting-mirror-type variable optical attenuator according to the present invention is formed of a collimator lens with optical fibers in which two optical fibers are attached to a rod lens in respective positions off-centered from the optical axis of the rod lens and a linearly movable reflecting mirror. A phenomenon that the optical axis of a light beam emitted from one optical fiber deviates from the optical axis of the collimator lens by the angle according to the off-centered distance on the surface of the rod lens is utilized. That is, by changing the distance between the surface of the reflecting mirror arranged to be linearly movable in the optical axial direction back and forth and the surface of the rod lens, input light from one optical fiber is attenuated to be output to the other optical fiber.

Abstract: A fin-stabilized projectile includes a projectile body having a rear portion defining a rearwardly open cavity and a stabilizing assembly which has an axially slidable fin support in the cavity. The fin support has a retracted position in which the fin support is withdrawn into the cavity and an outwardly shifted position in which the fin support projects from the projectile body.
