A field emission transistor uses carbon nanotubes positioned to extend along a substrate plane rather than perpendicularly thereto. The carbon nanotubes may be pre-manufactured and applied to the substrate and then may be etched to create a gap between the carbon nanotubes and an anode through which electrons may flow by field emission. A planar gate may be positioned beneath the gap to provide a triode structure.

Planar field emission transistor

A stroller for a child is disclosed which includes a frame having two support surface engaging rear wheels rollably mounted on opposite sides of a rear end portion thereof and a single, support surface engaging swivel caster suspended from a front end portion of the frame on a longitudinal centerline thereof. A pair of spaced apart front wheels is rollably mounted on opposite sides of a front end portion of the frame in transverse and laterally spaced apart alignment with the caster. The front wheels are mounted on the frame so that the lower surfaces thereof are spaced slightly above the lower surface of the caster, whereby the front wheels normally do not touch the supporting surface when the load on the stroller is balanced along the centerline thereof and when the stroller is either stationary or moving in a straight line. However, the rollable front wheels act to stabilize the stroller and prevent it from turning over by alternately tilting over into rollable engagement with the supporting surface, as when a person pushing the stroller attempts to execute a sharp right or left hand turn at a relatively high forward speed. The stroller includes a miniature automobile body mounted on and effectively concealing the frame from view. A box shaped seat is mounted on the frame between the front and rear wheels under an opening in an upper surface of the automobile body.
