Abstract: An end station for an ion implanter includes a loading station, a loadlock station, a vacuum chamber and a wafer handler within the vacuum chamber. The wafer handler includes a wafer-receiving platen assembly on the end of a multiple axis arm system wherein the arm system is capable of positioning the wafer for low and high angle of incidence implantation, rotating the wafer about an axis perpendicular to the wafer surface, and effecting scanning motion of the wafer along a straight line which intercepts the wafer tilt axis in any tilt position of the platen assembly. The invention further includes a loadlock including an upper element receiving wafers from the loading station and a lower element operable to position wafers for engagement by a transfer arm which transfers wafers from the loadlock to the wafer handler.

Abstract: A stabilized antenna system is disclosed. The stabilized antenna platform includes an acceleration displaceable mass which compensates for linear acceleration forces to inhibit tipping of the antenna platform. The stabilized antenna system may include in combination a gimbal mounting and one or more gyros.

Abstract: An interconnect system from a combination gyro and pendulum weight passive stabilization system unit and an equipment platform, such as an antenna platform, whereby the platform is position stabilized in pitch and roll as controlled by the passive stabilization system unit. The interconnect system may take the form of a selsyn system used with a generator and a motor interconnected by multiple wire circuitry to permit location of a passive stabilization system unit at an ideal location in an ocean-going ship, such as in the epicenter region of the ship, with minimized pitch and roll acceleration forces, and with the antenna platform stabilized thereby ideally located for antenna purposes as much as hundreds of feet away from the passive stabilization system unit.

Abstract: An antenna mounting structure is supported and oriented by three linear hydraulic actuators responsive to linear position transducers of a passive stabilization system serving as a vertical reference for keeping an antenna precisely pointed at a geostatically satellite during motion disturbances. The antenna is assembled with each of the linear actuators connected thereto through a gimbaled mount which facilitates accommodation of the requisite angulation thereof necessitated by motion in adjacent actuators. Response in each actuator is derived through an independent linear servo loop directly communicating with a linear position transducer constructed in scaled replication of the respective antenna actuator geometrical configuration and assembled to an inertially stabilized platform.

Abstract: A caging system for non-closed-loop gyro systems used in gyro stabilized platforms using fluid dashpots in place of automatic caging gyro brakes, torquers, or solenoids. A fluid dashpot is mounted on the gyro stabilized platform for each gyro of the platform with the linear motion of the dashpot along an axis normal to the median general rotational plane of the respective gyro of the platform. Movement of a dashpot linear movement member is greatly accentuated by the dashpot to gyro assembly interconnected linkage as roll component or pitch component amplitude exceeds designed operational gimbal roll and pitch ranges of respectively roll and pitch gyros of the platform.

Abstract: A multi-axis antenna pedestal with two controlled axes configured with elevation over azimuth on a gravity and gyro stabilized platform. The assembly is suspended with right-angled pivotal axes in substantially the same horizontal plane, and structure pivoted about the upper two controlled axes is statically balanced and the center of gravity of the entire pivotally mounted assembly is on the vertical axis and below the gimbal plane. The platform structure includes at least one gyro motor and rotor system pivotally mounted in the platform structure on an axis parallel to one of the right angled pivotal axes of the platform pivotal mounting. The center of gravity of the one gyro motor and rotor system is below its pivotal mounting in the platform structure, and when two such gyro motor and rotor systems are employed the pivotal mounting axes of each parallels an individual axis of the platform pivotal mounting.
