Abstract: A high resolution x-ray microscope for imaging microscopic structures within biological specimens has an optical system including a highly polished primary and secondary mirror coated with identical multilayer coatings, the mirrors acting at normal incidence.  The coating have a high reflectivity in the narrow wave bandpass between 23.3 and 43.7 angstroms and have low reflectivity outside of this range.  The primary mirror has a spherical concave surface and the secondary mirror has a spherical convex surface.  The radii of the mirrors are concentric about a common center of curvature on the optical axis of the microscope extending from the object focal plane to the image focal plane.  The primary mirror has an annular configuration with a central aperture and the secondary mirror is positioned between the primary mirror and the center of curvature for reflecting radiation through the aperture to a detector.  An x-ray filter is mounted at the stage end of the microscope, and film sensitive to x-rays in the desired band width is mounted in a camera at the image plane of the optical system.  The microscope is mounted within a vacuum chamber for minimizing the absorption of x-rays in air from a source through the microscope.

Title: Phase/frequency comparator for timing recovering circuit
Inventor: SARI HIKMET
IPC: H04L7/033
Filed: 1992-02-19
Granted: 1999-11-23
Abstract: The phase/frequency comparator comprises a known phase comparator for comparing the phases of an digital input signal with a clock signal of which the period varies to within one time interval with respect to the period of the input signal.      Such a phase comparator produces a first error signal whose sign, and preferably magnitude, vary as a function of the difference between the phases. The phase/frequency comparator is intended to produce a second error signal which replaces the first error signal and whose sign, and preferably magnitude, vary as a function of the difference between the periods.      According to a preferred embodiment, a phase shift assessing circuit detects a predetermined phase shift, e.g. substantially equal to 0, between the clock signal and the input signal during a clock period. A sign detecting circuit detects the sign of the difference between the periods for the predetermined phase shift, and a logic circuit derives two signals having pulse widths as a function of said periods thereby deriving the second error signal by differentiation.      The phase/frequency comparator is particularly intended for a phase locked loop for recovering the timing of the input signal.

Title: Free-electron laser oscillator for simultaneous narrow spectral resolution and fast time resolution spectroscopy
Inventor: MADEY JOHN M J
IPC: H01S3/09
Filed: 1990-08-20
Granted: 2001-07-03
Abstract: A technique for increasing the temporal resolution of the optical pulses white simultaneously increasing the spectral resolu-tion of the pulse train in a free-electron laser. The increase in temporal resolution is achieved by introducing a quadratic temporal phase variation (i.e. linear frequency chirp) across the optical pulses, and then propagating the outcoupled pulses through a dis-persive delay line such as a grating pair or prism pair in order to compress them to the transform limit of the broadened spec-trum. Essentially, the quadratic time dependence of the optical phase broadens the spectrum and yields Fourier components whose phase exhibits a quadratic frequency dependence. To operate a free-electron laser in such a configuration, electron micro-pulses with a linear time-dependent energy are produced in the RF linac by positioning the bunches slightly off the peak of the RF wave at phases where the field gradient is large. These electron micropulses are injected into the wiggler and lead to the for-mation of optical pulses with a corresponding linear time-dependent frequency.

Title: Method for diagnosing deficiencies and expanding a person's useful field of view
Inventor: BALL KARLENE K
IPC: A61B3/024
Filed: 1990-11-21
Granted: 1996-04-30
Abstract: A method for diagnosing deficiencies in and expanding the size of a person's "Useful Field Of View" (UFOV").  The UFOV is determined by the eccentricity (in degrees of visual angle) at which peripheral targets (presented within an embedding context) can be localized 50% of the time while performing a concurrent visual task in central vision.  The method provides multiple blocks of trials, each block of trials consists of displaying a plurality of times before a subject's vision a set of four sequentially presented images having specific characteristics, and the specific characteristics of each block of trials is changed each time a new block of trials is displayed before the subject.  By changing the characteristics of each block of trials, a diagnosis can be made of the subject's vision by creating a subject database that contains the subject's indicated responses to each block of trials having specific characteristics and comparing the subject database to a normative diagnostic database in order to achieve a diagnosis.  The method also employs training programs to expand the size of the subject's UFOV.

Abstract: A floral support assembly for presenting a display of fresh cut flowers.      Floral foam is bonded to a backing to define a pre-shaped configuration. Moisture barrier means, preferably in the form of ambient air spaces, separate the floral foam into adjacent segments of predetermined dimensions, in at least the vertical direction. The barrier spaces have a predetermined width sufficient to prevent floral preservative solution from bridging between adjacent segments when the floral foam support assembly is inclined with respect to a horizontal frame of reference. The preferred method by which to saturate the aforesaid assembly with a floral preservative solution requires a container. At least a sufficient volume of the preservative solution is placed in the container to saturate the foam segments on whatever number of support assemblies are to be simultaneously processed. The support assemblies are then floated in the solution with the foam segments facing the solution. Each assembly is removed from the solution after it has been permitted to sink into the solution to a predetermined depth. The assembly is then inverted and placed on a horizontal surface for a predetermined period of time with the backing resting on that horizontal surface. The stems of flowers may then be inserted into the foam segments to fashion a display.

Title: Power conversion control apparatus
Inventor: NAKAMURA NAOMI
IPC: H02M7/162
Filed: 1993-08-13
Granted: 1995-12-26
Abstract: A power conversion system has a control circuit constituted by a dual system. The control circuit of each system is equipped with a current control circuit.  The current control circuit has a selection circuit that, after determining the magnitude of the output of an integrating amplifier of its own system and the output of an integrating amplifier of the other system, selects one of the outputs of the two integrating amplifiers.  The selection  circuit applies  a  signal  responsive to a difference between the output of the integrating amplifier of its own system and the output of the selection circuit of its own system as correction signal to the input of the integrating amplifier of its own system.    Accordingly, when the power conversion system is utilizes a dual control system, even when the current control circuit includes an integration algorithm, control can be performed by the two systems without saturation due to the integration algorithm.
