  • Patent number: 4508076
    Abstract: The idling speed of an internal combustion engine is controlled by controlling the position of a control valve disposed in the intake system of the engine to control the amount of intake air fed to the engine. A desired idling speed is determined according to the operating condition of the engine and the control valve is moved to a temporary target position which is expected to be suitable to obtain the desired idling speed. Then feedback control is carried out to converge the actual idling speed to the desired idling speed. When the actual idling speed is finally equalized to the desired idling speed, the actual position of the control valve at that moment is detected and memorized to be adopted as the temporary target position for the same operating condition in later control of the idling speed.

  • Patent number: 4501225
    Abstract: A magnetic metal deposition material contained in a hearth is heated and evaporated in a vacuum to form a flow of vapor, which is then ionized and converged toward a predetermined deposition surface of a flexible substrate. The flexible substrate is moved obliquely downwardly along a convex course by sliding contact with the curved surface of a fixed curved guiding body between a pair of guide rollers located at different heights above the hearth. The fixed curved guiding body communicates with a coolant source for cooling the substrate moving in contact therewith and may be provided with oscillators. Thus a thin film of the magnetic metal is deposited on the convex surface of the substrate.

  • Patent number: 4497015
    Abstract: A device for providing an illumination of an object includes first and second optical integrators disposed on an optical axis in spaced-apart relationship. Light rays emitted from a point light source formed by an elliptical reflector mirror having a light-emitting source are incident on the first optical integrator, which forms a plurality of secondary images of the point light source. The second optical integrator receives luminous fluxes emitted from the secondary light source images to form a multiplicity of secondary images of the secondary light source images formed by the first optical integrator. Luminous fluxes from the secondary images formed by the second optical integrator are superimposed by a condenser lens on the object for illuminating the latter with light beams of uniform intensity.

  • Patent number: 4491497
    Abstract: The invention relates to a hand labeling apparatus for printing and applying adhesive labels on articles. The apparatus comprises a printer (21) held by a printer carrier (20) which is pivotable between an inoperative and an operative position. In the inoperative position the printer carrier (20) holds the printer (21) lifted off an adhesive label (11) lying on a printing platen (14), while in operative position it holds the printer (21) in contact with the adhesive label (11). By drive means (3, 30, 5) the printer carrier (20) can be moved from the inoperative into the operative position and can be automatically returned to the inoperative position under the influence of a resetting force. In order to prevent double imprints on the adhesive label the device includes retaining means (46, 60) which hold the printer carrier (20) in the operative position with a retaining force that is less strong than the resetting force.

  • Patent number: 4489259
    Abstract: A method and apparatus for controlling a stepper motor and a disk drive is described for minimization of stepper motor oscillations for a single step, minimizing the time taken for the stepper motor to move between tracks for multi-track seeks, and reduction of angular hysteresis due to the mechanical and magnetic properties of the stepper motor construction.This control is achieved using a microprocessor-based circuit adapted to drive the stepper motor in accordance with predetermined programs. Oscillations of the stepper motor are damped by controlling, using one program, the current applied to the stepper motor during the last step of its motion by switching this current on and off within small predetermined time intervals. The time taken to move between tracks is controlled by another program in which the non-linear torque speed characteristics of a particular stepper motor are matched by a non-linear pulse rate which is determined by data held in the memory of the microprocessor circuit.
