    摘要: A phase correcting apparatus, for a radio transmitter which obtains a first radio signal (RS1) based on a first baseband signal (BB1), includes a demodulator which demodulates a feedback signal from which a part of RS1 is extracted by a first carrier signal (CS1) and which generates a second baseband signal (BB2), a modulator which modulates a difference signal between BB1 and BB2 by a second carrier signal (CS2) and which outputs a second radio signal (RS2), a power amplifier which amplifies RS2 to obtain RS1, a detector which detects a phase difference between BB1 and BB2, and a phase rotator which rotates any phase of BB1, BB2, CS1, or CS2 as a target phase correction amount, wherein the detector converts a desired analog signal obtained by multiplying BB1 and BB2 into a digital signal, and which detects the phase difference based on digital data.

    摘要: A universal joint hinge assembly for a tuned rotor gyroscope is insensitive to restraint changes due to spin axes accelerations. The hinge assembly is readily trimmable at the gyroscope wheel assembly to permit adjusting of the axial compliance of the gyroscope wheel thereby reducing the rectified torques due to linear acceleration.

    摘要: A gimballed platform stabilization system includes at least one outer member, an inner member, and an intermediate inertia bearing member. The intermediate member has limited coaxial angular freedom about an isolation axis with respect to the inner and outer members. A limited freedom (about the isolation axis) torsional flexure element is coupled between the intermediate and inner members. A first servo loop establishes a "negative spring rate" in parallel with the positive spring rate associated with the flexure element, maintaining a low net effective spring force on the inner member. A second servo loop prevents the angular excursion between the intermediate member and the inner member to extend beyond the limits of the flexure element. This inertia reaction stabilization configuration reduces disturbing torques from a stabilization axis to non-linear spring residuals which are relatively small.

    摘要: A flexure suspension assembly is provided for coupling the rotatable spin shaft and flywheel of gyroscopes of the type having relative angular rotation between the shaft and flywheel about two precession axes orthogonally related to the spin axis. A cylindrical central spin shaft mounting member is coupled by a first pair of single axis flexure joints to a first bifurcated gimbal member to permit angular rotation of the gimbal about one precession axis and is coupled by a second pair of single axis flexure joints to a second bifurcated gimbal member to permit angular rotation of the second gimbal about the other precession axis. The gimbal members are interleaved and form segments of an annulus concentrically disposed about the central mounting member. An annular flywheel mounting member is concentrically disposed about the annulus and is connected to the first gimbal member by a third pair of single axis flexure joints which permit angular rotation of the annular mounting member with respect to the first gimbal about said other precession axis and is also connected to the second gimbal by a fourth pair of single axis flexure joints which permit relative angular rotation between the annular mounting member and second gimbal about said one precession axis.

    摘要: An improved flexure hinge suspension for use in free-rotor displacement type gyroscopes is provided comprising an inner hinge unit and an outer hinge unit concentrically nested one within the other in a generally parallel manner coaxial with the gyro''s spin or reference axis. Each hinge unit, in turn, comprises a frictionless, four-bar, two-axis, universal-joint suspension element for supporting the gyro''s inertial flywheel relative to the spin axis in a particular directional mode. That is, in the outer hinge unit, the flexure bars have their respective longitudinal axes arranged perpendicular to the spin axis so as to support the flywheel against torsional and radial displacements relative to the spin axis while in the inner hinge unit the flexure bars have their respective longitudinal axes oriented parallel to the spin axis so as to support the flywheel against axial displacements along the spin axis. In each hinge unit the flexure bars comprise locally thin necked-down sections formed by machining a corresponding pair of closely spaced holes completely through the peripheral wall of each unit as the case may be. Thus, when the two units are positioned relative to each other before being rigidly fastened together, the desired exact orthogonal alignment between the flexure bars in the outer unit and the corresponding flexure bars in the inner unit may be facilitated by a simple visual inspection thereof. The flexure hinge assembly furthermore includes angle stop means for safely limiting the angular displacement of its hinge gimbals thereby preventing the delicate thin flexure bars from being overstressed or ruptured in operation.
