Abstract: A flight management system for a plurality of aerial vehicles includes a management apparatus and an operation terminal. The management apparatus includes processing circuitry to manage operation authorizations to operate the plurality of aerial vehicles. The operation terminal includes an operation interface and processing circuitry. The operation interface is operable by an operator. The processing circuit is connected to the operation interface. Based on an authorization grant request signal obtained based on a flight state of each aerial vehicle of the plurality of aerial vehicles, the processing circuit of the management apparatus transmits an authorization grant command to grant the operation terminal an operation authorization, among the operation authorizations, that is to operate a particular aerial vehicle among the plurality of aerial vehicles.

Abstract: A flight control apparatus for a helicopter is configured by: a control unit controlled by the pilot; a steering mechanism for generating an aerodynamic control force; a link mechanism for mechanically transmitting an amount of control Ma in the control unit to the steering mechanism, thereby driving the steering mechanism; an amount-of-control sensor for detecting the amount of control Ma in the control unit and for supplying a control signal Sa; a flight control law calculation unit for calculating a flight control law of the helicopter based on the control signal Sa, and for supplying a driving signal Sb for the steering mechanism; a difference calculation unit for subtracting the control signal Sa from the driving signal Sb, and for supplying a difference signal Sc; and a precision servo actuator unit for adding the amount of control Ma transmitted via the link mechanism, to an amount of difference Mc corresponding to the difference signal Sc.

Abstract: A servo actuator apparatus has: an actuator which relatively displaces an operation unit on the basis of an input signal E1; a position sensor which detects a relative position of the operation unit and outputs a detection signal D1; an actuator which relatively displaces an operation unit on the basis of an input signal E2; a position sensor which detects a relative position of the operation unit and outputs a detection signal D2; a difference calculation unit which subtracts the detection signal D2 from a command signal C1 supplied from a flight control computer, to output the input signal E1; and a difference calculation unit which subtracts the detection signal D1 from a command signal C2 supplied from a flight control computer, to output the input signal E2, where a positive displacement direction of the operation unit is reverse and series to that of the operation unit, and the body units of the actuators are integrally movable, and the actuators can always operate while mutually monitoring the actual o

Abstract: According to a first aspect of the invention, an optical position sensor employs a position encoder having collimators and reflectors with mutually aligned optical axes mounted in a support. A slotted code plate moves between the collimators and reflectors in a plane non-perpendicular to their optic axes. This encoder converts position to optical signals reliably, regardless of mechanical shock or vibration. According to a second aspect of the invention, an optical position sensing system employs wavelength-division multiplexing to distribute light pulses to different position encoders and time-division multiplexing to further distribute pluses to the collimators in each encoder. This permits multiple position encoders to be served by a single light source and optical fiber.

Abstract: An apparatus for feeding and discharging reels from a machine for winding video tape on reels of a cassette. The machine has a winder for winding video tape on a pair of reels and a feeder for feeding vacant reels to the winder and taking out the reels with video tape wound thereon. The feeder of the invention has a feeding conveyor for transferring a tray on which a pair of vacant reels are removably mounted, a discharge conveyor for transferring a tray on which a pair of reels with video tape wound thereon is mounted, and a supply and discharge device for connecting the discharge conveyor, the feeding conveyor and the winder.

Abstract: An apparatus for winding video tape on reels of a cassette includes a winding device for winding video tape on the reels and a feeding device for feeding a pair of reels to the winding device, the winding device having two shafts on which two reels can be removably mounted, at least one of the shafts being movable in a direction away from the other, a connecting member for connecting tapes being provided so as to be brought in and out of the path of movement of the movable shaft, the connecting member being out of the path of the reels when the reels are being moved away from each other, and when the reels are spaced from each other, the connecting member is moved in and out of the space between the reels so as to connect the tape wound on the reels with video tape.

Abstract: An apparatus for feeding pairs of reels to a winding position in a winding apparatus for winding video tape on the reels and removing the loaded reels from the winding apparatus. A feeding conveyor feeds trays containing a pair of empty reels removably mounted in the trays to a transfer position and carries trays into which pairs of loaded reels have been placed away from the transfer position. A rotating arm carries holding members at the ends thereof for gripping a pair of reels in a tray at the transfer position and gripping another pair of reels on the winding apparatus at the winding position. Movement of the arm along the axis of rotation removes the reels from the tray and the reels from the winding position, and rotation of the arm switches the reels from the tray to the winding position and vice versa. Thereafter the arm is moved axially to load the empty reels onto the winding machine and the full reels onto the tray.
