    摘要: The present invention provides an aqueous composition and process for electrodepositing a layer of a ductile, strongly adhering, adsorptive and/or absorptive zinc coating or zinc coating comprising silicon and phosphorous on a metal substrate. The electrodeposition composition is prepared by reacting metallic silicon and zinc with phosphoric acid and an alkali metal hydroxide in the ratio of between 0,4 and 1,3 moles of alkali metal hydroxide per mole of phosphorus acid, and adjusting the solution to a pH of 1 or higher after completion of the reaction. The coating is deposited on the metal substrate by electrodeposition and comprises about 70 to 99,5% by weight of zinc, and about 0,1 to 10% by weight of silicon, and about 0,5 to 20% by weight of phosphorus.
    The resulting Zn/Si/P coating improves the resistance of the metal substrate to corrosion, wear, galling, stress corrosion cracking and cracking during mechanical forming operations. While essentially all metals of industrial importance may be coated, this process is especially important for ferrous metals, steels, stainless steels, copper, aluminium, chromium and titanium.

    摘要: A stator arrangement particularly suitable for use in an air-cooled generator or other such electric machine includes a stator with an outer stator surface, an opening therein defining an inner stator surface, and longitudinally opposed stator end surfaces. Conductive coils are supported by the stator, and include end turns overlying the longitudinally opposed stator end surfaces. In order to block out environmental contaminants and prevent conductive coil shorting, protective barriers are mounted over the end turns and secured to the stator.

    摘要: A hybrid stepper motor includes a stator having a number of poles. Teeth are formed on the stator poles and separated from each other by slots. A magnet is inserted in the slots to a predetermined depth from a top surface of the stator teeth. The motor further includes a rotor that is provided coaxial with the stator. Teeth are also formed on the rotor opposite the stator teeth. The rotor teeth enable the rotor to be rotated relative to the stator in cooperation with the stator teeth.

    摘要: High precision position control apparatus. An object supported on a frame of reference (10) is moved by an actuator (14). A position sensor (16) generates a position signal and an acceleration sensor (24) affixed to the frame of reference (10) generates an acceleration signal. A control system responds to the position signal and the acceleration signal to control the actuator (14) to move the object to follow a commanded trajectory with reduced following error.
