International Classification:

G01J 1/00

US Classification:

2503361

Abstract:

Arrangements for the point-to-point imaging of a broad spectrum of electromagnetic radiation and ultrasound at large angles of incidence employ matched pairs of spherically bent reflectors to eliminate astigmatic imaging errors. Matched pairs of spherically bent crystals or spherically bent multi-layers are used for X-rays and EUV radiation; and matched pairs of spherically bent mirrors that are appropriate for the type of radiation are used with microwaves, infrared and visible light, or ultrasound. The arrangements encompass the two cases, where the Bragg angle—the complement to the angle of incidence in optics—is between 45 and 90 on both crystals/mirrors or between 0 and 45 on the first crystal/mirror and between 45 and 90 on the second crystal/mirror, where the angles of convergence and divergence are equal. For x-rays and EUV radiation, also the Bragg condition is satisfied on both spherically bent crystals/multi-layers.

US Classification:

292343, 292342, 292339

Abstract:

An apparatus for assisting handicapped people in opening doors. The apparatus is used primarily for individuals in wheelchairs, who typically have difficulty in opening doors. The apparatus has a long shaft with two ends, and has a handle attached to one end of the shaft. The other end of the shaft has both a wedge and a pull pin attached to it. The wedge is used to keep an opened door in an open stage by placement underneath the door in between the bottom of the door and a ground surface. The pull pin is used for placement behind a door handle to effectively “pull open” a door.

International Classification:

G01T 136

US Classification:

378 82

Abstract:

Spherically or toroidally curved, double focusing crystals are used in a spectrometer for X-ray diagnostics of an extended X-ray source such as a hot plasma produced in a tokomak fusion experiment to provide spatially and temporally resolved data on plasma parameters using the imaging properties for Bragg angles near 45. For a Bragg angle of 45. degree. , the spherical crystal focuses a bundle of near parallel X-rays (the cross section of which is determined by the cross section of the crystal) from the plasma to a point on a detector, with parallel rays inclined to the main plain of diffraction focused to different points on the detector. Thus, it is possible to radially image the plasma X-ray emission in different wavelengths simultaneously with a single crystal.

International Classification:

A61N 5/10
A61L 31/02
A61L 31/14

Abstract:

A system/apparatus and a positioning method for the determination of the delivery of protons within a mammalian body or inanimate medium, as well as a treatment method which comprises the delivery of protons to a mammalian body. The system/apparatus necessarily comprise the use of a detector which is placed in the proximity of the body or medium which is responsive to a signal emitted from a fiducuial marker which his positioned within or in the near proximity of target tissue within the body or target volume within the medium. A signal emitted from the fiducial marker is responsive to the impingement of protons thereon received from a controlled proton beam, the signal may be used to modify the subsequent operative characteristics of the source of protons.

Abstract:

Disclosed is an imaging apparatus for EUV spectroscopy, EUV microscopy, EUV lithography, and x-ray imaging. This new imaging apparatus could, in particular, make significant contributions to EUV lithography at wavelengths in the range from 10 to 15 nm, which is presently being developed for the manufacturing of the next-generation integrated circuits. The disclosure provides a novel adjustable imaging apparatus that allows for the production of stigmatic images in x-ray imaging, EUV imaging, and EUVL. The imaging apparatus of the present invention incorporates additional properties compared to previously described objectives. The use of a pair of spherical reflectors containing a concave and convex arrangement has been applied to a EUV imaging system to allow for the image and optics to all be placed on the same side of a vacuum chamber. Additionally, the two spherical reflector segments previously described have been replaced by two full spheres or, more precisely, two spherical annuli, so that the total photon throughput is largely increased. Finally, the range of permissible Bragg angles and possible magnifications of the objective has been largely increased.
