摘要： An apparatus for generating a magnetic biasing field for recording in a magneto-optical medium, including a coil mounted on a core and connected in parallel with a capacitor and a first switch, and a control circuit for generating a first pulse for opening and closing of the first switch upon each transition of an information signal to be recorded, thereby to produce magnetic flux inversions in the core. A second coil is mounted on the same core as the first coil. Second and third switches are connected in series between positive and negative voltages, and a series connection point between the second and third switches is connected to the second coil, the other end of which is connected to ground. Second and third pulses of fixed duration are applied to the second and third switches based on the trailing and leading edges of the information signal to be recorded, respectively. Monostables are used to generate the first, second and third pulses. The control circuit includes the monostables.

摘要： An optical device for forming a stigmatic image of a laser source positioned at a predetermined point is intended to illuminate a reflecting surface while also providing a separation between the beam emerging from the source and the beam reflected from the surface. The device comprises a cube placed against a converging lens, the dimensions of the assembly thus formed being such that the cube face remote from the lens passes through a Weierstrass point of the spherical refracting surface formed by the lens. The laser source is positioned at the Weierstrass point. The cube is formed by two prisms cemented together, the interface being treated so as to have a polarization-separating effect.

摘要： The optical reader, for information discs of which the items of information are locatable by addresses previously recorded on each of the grooves forming the track, comprises a device for counting the number of grooves traversed during search phases which simultaneously uses the envelope of the reading signal and the signal representing the radial error in the position of the head relative to the nearest track, for algebraically counting the number of tracks traversed. After comparison with the number of grooves to be traversed, the counting device controls the deceleration of the radial advance when the spot is at a predetermined distance from the groove to be reached and also its total stoppage and the closure of the radial servocontrol loop when the groove is reached.

摘要： The field of the invention is that of devices for detecting non-metallic objects concealed on human subjects. These devices are more particularly dedicated to the surveillance and protection of reserved access areas, such as airport areas. The device according to the invention comprises a portable detector comprising a transmitter and a receiver of microwave frequency signals disposed in an enclosure of chaotic geometry including a plurality of measurement holes. The microwave frequency signal measured by this detector depends on the nature of the objects disposed under the holes. A processing device linked to this detector is used to correlate the measured signals with prerecorded signals. When the correlation exceeds a certain threshold corresponding to the presence of suspect objects, an alarm is generated.
