Abstract: An electromagnetic electron reflector, an ion implanter having an electromagnetic reflector and a method of implantation using the ion implanter. The electromagnetic electron reflector includes a frame; permanent magnets within the frame; a center aperture within the frame and electrically isolated by first gaps from the frame and the permanent magnets and fixed in position by dielectric feed throughs, first cup shields integrally formed on the top and bottom edges of the center aperture, the dielectric feed throughs nested within the first cup shields; second cup shields integrally formed on inside surfaces of the top and bottom of the frame, the second cup shields nested within respective first cup shields; entrance and exit apertures attached to the frame and an electrical conductor passing through at least one of the dielectric feed throughs and electrically contacting the center aperture.

Abstract: An automatic shrink shock strut for use in conjunction with aircraft landing gear. The landing gear is of the type which includes a shock strut cylinder and a shock strut piston mounted coaxially therewith, and defining there between a shock strut shrink chamber filled with hydraulic fluid and a gas spring chamber filled with a pressurized gas. During retraction of the landing gear, the mechanism transfers the pressurized gas from the gas spring chamber to a transfer cylinder and therein drives a volume of hydraulic fluid from a hydraulic fluid supply in the transfer cylinder to the shock strut shrink chamber. The shock strut responds by shrinking to a shortened length. During extension of the landing gear the mechanism returns works in reverse and returns the pressurized gas to the gas spring chamber to drive the volume of hydraulic fluid from the shock strut shrink chamber back to the hydraulic fluid supply, thereby extending the landing gear to its normal length.
