Abstract: An optical target orienting system including a mount defining a pan axis, an optical target positioned on the mount, the optical target being rotatable relative to the mount about a tilt axis, a pan assembly operatively connected to the mount to rotate the mount and, thus, the optical target about the pan axis, and a tilt assembly operatively connected to the optical target to rotate the optical target relative to the mount about the tilt axis.

Abstract: A shift register which receives a transmission clock signal, which is shifted according to the transmission clock signal, and which outputs a gate signal a predetermined time after reset; a reset circuit which outputs a reset signal for resetting the shift register when the reset circuit receives an input of a step signal for driving the stepping motor; and a switching element which receives the gate signal of the shift register and which is switched between a blocked state and a conductive state are provided in a driving circuit of a stepping motor.

Abstract: A manipulator has a working unit including an end effector and a posture axis for changing the orientation of the manipulator, a compound mechanism provided on the working unit, and a controller for actuating a gripper axis, a yaw axis, and a roll axis by respectively controlling movement positions of three motors. The controller includes a torque generation detector for detecting a timing at which torque is generated on the gripper axis. When the controller detects the timing at which a torque ?g? is generated on the gripper axis under operation of a given motor, the movement positions of the plural motors are shifted and set, corresponding to the directions at which interference torques are generated with respect to the yaw axis and the roll axis, and to predetermined positions of the same directions.

Abstract: In a device, such as measuring or control signal transmitter, generating an analog current or voltage output signal, absolute values of output variables are continuously measured and regulated to ensure the correctness of the signal. The actual current or voltage value of an analog output signal is measured and digitized (206), a difference (e) between the digitized actual current or voltage value and the desired current or voltage value is defined (300), and the generation (200, 202, 204, 205) of the analog output signal is controlled (304) by means of a digital control signal (Enable, Direction) so as to decrease the difference.

Abstract: An operation apparatus is designed for use with a system to deal with operation information of the system. In the operation apparatus, an operation piece is manually operable to move in a linear or circular direction to a position indicative of the operation information. A detection section detects the position of the operation piece and outputs position data corresponding to the detected position. A drive section responds to position data inputted from the system to automatically move the operation piece to a position corresponding to the inputted position data. An acquiring section provisionally acquires a plurality of reference position data which are outputted from the detection section when the operation piece is placed at a plurality of reference positions such that the respective reference position data correspond to the respective reference positions.

Abstract: A flux valve compass heading repeater system is provided with a compensating system which, when connected to a three-legged flux valve, provides fully compensated, three-wire output signals of the synchro data transmitter type for direct use in apparatus requiring precision three-wire heading data. The compensating system includes control circuits for generating sine and cosine components of magnetic heading and for compensating them for typical compass errors such as those induced by changes in operating latitude and two cycle and index errors. Latitude compensation is accomplished by a novel proportional automatic gain control; two cycle cardinal heading error compensation is accomplished by a compensation circuit having only a single manual control, while index error compensation is similarly accomplished by a compensation circuit requiring only a single manual control.
