    摘要: The film deposition rate of metallic compounds onto a substrate in a vacuum chamber by reactive sputtering or reactive ion plating is significantly increased by providing a substrate support with spaced apart magnetic poles to create a magnetic field having lines of force which leave the support, extend across a surface of the substrate exposed to a metallic coating source and re-enter the support to enclose the exposed surface in a localized magnetic electron-trapping field. A reactive gas is fed into the chamber, and a bias voltage is applied to the substrate support sufficient to create a dense glow discharge of ionized reactive gas closely adjacent to the substrate surface. The reactive gas ions react with metallic particles deposited on the exposed substrate surface from the coating source to form a film of the desired metallic compound. The localized magnetic plasma trap close to the substrate increases the chemical reaction rate at the substrate and reduces back sputtering, to result in a metallic compound coating having superior physical and chemical characteristics.

    摘要: A cathode assembly for use in a magnetron sputtering system, the system having a cathode assembly with parallel elongated target segments which are formed substantially of a material which is desired to be sputter-deposited onto a substrate. The elongated target segments are each provided with a material removal surface which is inclined toward the other segment with respect to the plane of the substrate. Such inclination permits the material which is removed from the target bars to be focused onto a relatively narrow area, thereby improving the efficiency of the sputtering operation and reducing machine down-time for cleaning and vacuum pumping. In other embodiments, end target segments are provided for improving the efficiency of film deposition near the ends of the elongated bars. The end target segments are provided with material removal surfaces which are also inclined, and connect with the elongated target segments to form a rectangular frame arrangement.

    摘要: A brushless DC motor is controlled by determining a speed of the motor and a line voltage supplying drivers of the motor. Based upon these determined values and predetermined motor performance data, a maximum PWM on-time is determined for drive signals supplied to windings of the motor. This maximum PWM on-time thereby limits motor torque output to a predetermined maximum. Stopping the motor is performed in sequential phases including a loaded generator phase, an active braking phase and a holding phase. During holding, the amount of energy supplied to the motor is reduced to the point just before slippage such that holding energy is minimized. Upon power failure, the motor is driven toward a spring return home position overcoming static friction that may prevent the spring return mechanism from functioning properly. These techniques are applied to a motor in an actuator.

    摘要: A roller-chain conveyor includes a guide plate to support the load carried by the roller-chain conveyor belt, and to maintain the roller-chain on a consistent track. A guide plate is carried on top of a stiff foundation plate to resist load-induced deflection. Foundation plates desirably carry hold-down structure adapted for reception in socket structure formed in the guide plate. Operable socket structure can be formed to include a T-slot. A cooperating hold-down structure is a mushroom-shaped peg affixed to the foundation plate. Such a guide plate is installed by lowering the guide plate onto the foundation plate to place the peg into reception in the socket. Then, the guide plate is slid axially to engage a rim of the T-slot under the mushroom head. One or more fasteners is then typically placed through the guide plate and into the foundation plate to resist axial motion effective to decouple the peg and socket. Guide plates desirably are made from a plastic material, such as Tyvar 88.

    摘要: A system and method of providing floating actuator control is provided. This system and method receives input command signals from an actuator controller, and effectively integrates these signals until the controller has requested a large enough movement of the actuator that the actuator can actually effectuate. At this point, the system and method drive the actuator to the commanded position. As a result, excessive mechanical wear in the actuator caused by small command signal perturbations and dither is reduced or eliminated.
