    摘要： An improved solid state commutated linear motor (18) with an ironless multiphase armature (20) is disclosed which has a magnetic field array (11) having periodic alternating polarity, an ironless multiphase armature, and a solid state commutating system for driving a moving element (34) and positioning it with respect to a reference element (32). In one embodiment, the magnetic field array is elongated and fixedly located with respect to the reference element, and the ironless multiphase armature is fixedly located with respect to the moving element. In a second embodiment, the ironless multiphase armature is elongated and fixedly located with respect to the reference element, and the magnetic field array is fixedly located with respect to the moving element. The magnetic field array is generated by an array of spaced alternate north and south poled magnets having an inter-pole distance L. The ironless multiphase armature is comprised of coils having a center-line span equal to the inter-pole distance L, wherein the coils are interleaved and staggered to form the various phases. Solid state switches (74 to 84) are used to commutate the phases by first faulting a phase as it approaches a space between magnetic poles and then reversing the connections of that phase as it leaves the space between the magnetic poles.

    摘要： Improved catoptric reduction imaging systems of a quassi-Cassegrainian type are presented wherein light from an object enters an imaging system through an aperture in one mirror of an imaging system and leaves the imaging system through an aperture in another mirror of the imaging system to form an image. In each imaging system, the sums of the inverses of the radii of the mirrors effecting each reflection are constrained to be substantially zero. In a first improved catoptric reduction imaging system, two mirrors (12, 14), one convex and one concave of equal base radii, are disposed axially, light from the object (16) enters the imaging system through an aperture in the concave mirror (14), reflects from the convex mirror (12) to the concave mirror and reflects from the concave mirror to form the image (20) positioned beyond the convex mirror through an aperture (22) in the convex mirror. Three alternative arrangements are disclosed.
