A power supply start up booster circuit for providing an increased startup voltage for a switch mode control integrated circuit including a boost portion for combining a first input voltage that has a predetermined minimum value and a second input voltage that transitions from 0 volts to the predetermined minimum value to make a minimum threshold voltage, a control portion having an integrated circuit for using the minimum threshold voltage to temporarily provide a voltage input at the integrated circuit, and an output portion for providing a permanent voltage input at the integrated circuit and an output supply voltage to an external circuit.

Power supply start up booster circuit

A suspension apparatus for the rear wheels of a motor vehicle includes a pair of control arms pivotally connected to the vehicle frame or body at one end and rotatively supporting the wheels by an improved structure which mechanically entraps a wheel spindle at the other end and a transverse torsion member extending between the control arms at a longitudinal position intermediate the ends. The torsion member is formed as a downward opening U-shaped channel member to position its shear center above the pivotal axis of the control arms to effect an understeer handling characteristic and is supported adjacent the control arms by gusset plates. Unique internal reinforcing braces are positioned in the channel member at the inner terminus of the plates to enhance the apparatus' resistance to fatigue failure.
