  • Patent number: 7007960
    Abstract: A vehicle suspension system includes features which reduce stress in an axle connection. In a described embodiment, a vehicle suspension system includes a sleeve which is clamped on an axle. The sleeve is retained in its clamped position and is welded to opposing side walls of an arm. A bottom plate of the arm may also be welded to the sleeve.
    Type: Grant

  • Patent number: 5559660
    Abstract: A method and apparatus for preventing current inrush upon the application of power to a load includes the steps of applying a first increasing DC voltage from a voltage source to the load through a single signal path which includes a transistor having a control electrode coupled to the voltage source and a second electrode coupled to the load. The transistor has a first operating region with an ON resistance characteristic which decreases between first and second applied control voltages. The transistor has a second operating mode in which the transistor has a relatively low on resistance R.sub.ON. The transistor is thus disposed in the single signal path to both limit inrush current and to provide a low loss signal path between the voltage source and the load.

  • Patent number: 5519264
    Abstract: A method and apparatus for preventing current inrush upon the application of power to a load includes the steps of applying a first increasing DC voltage from a voltage source to the load through a negative temperature coefficient device having a first terminal coupled to the voltage source and a second terminal coupled to the load and after a preselected period of time, bypassing said first and second terminals via a bypass circuit and coupling the increasing voltage to the load through the bypass circuit.

  • Patent number: 4747589
    Abstract: A printer table including a series of angled jets for sources of air and for sources of vacuum and also including a set of locating pins. The combination enables the use of the directed jets to move a substrate into position for processing and to hold the substrate in position once located by the locating pins with the use of a vacuum. Because the substrates are very thin and the locating pins are very short, the combined use of the vacuum and directing jets effectively permit the substrate to float on air in close proximity to the table surface while not overriding the locating pins.
