Filed: 1996-03-19
Abstract: A small field scanning photolithography system (700) has a double pass Wynne-Dyson optical system (770) which provides an erect, non-reverted, unmagnified image. An optical path through the system passes from an object (722), reflects off an input reflector (731), passes through a first quadrant of a lens (740), reflects off a concave mirror (750), passes through a second quadrant of lens (740) into folding optics (732) where an intermediate image forms, passes from folding optics (732) through a third quadrant of lens (740), reflects off concave mirror (750) a second time, passes through a fourth quadrant of lens (740), and finally reflects off an output reflector (733) to a plane (160) where a final image (362) forms. Typically, input and output reflectors (731, 733) and the folding optics (732) are prisms. A field stop (760) may be provided in folding optics (732) where the intermediate image forms. Magnification adjusting optics (710, 720) can be added to input and output prisms (731, 733) or to folding optics (732). The magnification adjusting optics (710, 720) forms two narrow meniscus air gaps (713, 723) which are equal size for unity magnification. Narrowing one air gap (713 or 723) and widening the other air gap (723 or 713) changes magnification slightly.

Abstract: The invention provides a multiaxis closure hinge for pivotally mounting a closure panel adjacent to an opening in a body to rotate about a point remote from the hinge between a closed position over the opening and an open position disposed apart from the opening. The hinge includes a body pintle, having an inner and an outer end, with body mount means at the outer end thereof for pivotally mounting the body pintle to the body for rotation about a first axis; a panel pintle, having an inner and an outer end, with panel mount means at the outer end thereof for pivotally mounting the panel pintle to the panel for rotation about a second axis; and coupling means for rotably coupling the inner ends of the body pintle and panel pintle together to rotate about a third axis; wherein the first, second and third axes intersect at said point during rotation between the open and closed positions. In a preferred embodiment the body pintle and panel pintle comprise elongate rods the inner end having an axis disposed at a predetermined angle relative to an axis of the outer end. The pintles include retainer means for axially securing the pintle ends to the mount and coupling means, such as press fit retainer bushings. The mount means comprise a flanged bearing mount, and the coupling means comprise a coupling block having means for coupling the inner end axes at an acute angle, and for fixing one said pintle to the coupling block to prevent relative rotation therebetween. Preferably each component of the hinge,(i.e.: body pintle, body mount means, panel pintle, panel mount means and coupling means) has a plane of symmetry enabling the hinge to be used for left and right installation. As a result of the novel structure, standard components can be mass produced to reduce costs and any modifications required to suit a particular application can be accomplished merely by redesigning the bent cylindrical pintle rods. Significant retooling costs can thus be avoided.

Title: Method and apparatus for a unique word differential detection and demodulation using the unique word differential detection
Inventor: POWIERSKI DARREN
IPC: H04L27/22
Filed: 1997-11-26
Abstract: A unique word differential detection system of the present invention is intended to provide a system that can expand a measurement range for the carrier frequency offset of the quasi-synchronized detection signal while maintaining detection of unique word position at a high accuracy, and maintaining a resolution for the carrier frequency at a low level. To this end, in an initial acquisition mode, it uses a first UW differential detection circuit with the number of delay symbols N (0.5 , N ~ 1) and a second differential detection circuit with the number of delay symbols N/2 to generate a first UW detection signal of a first quasi-synchronized detection signal and first frequency offset information.  The first frequency offset information reduces frequency offset of a second quasi-synchronized detection signal for demodulating a data signal.  Then, the mode turns to a fine tune acquisition mode, where a third UW differential detection circuit with the number of delay symbols M (1 , M) operates, and generates a second UW detection signal and a second UW detection signal for double check when it detects a UW from a third quasi-synchronized detection signal.
