Title: Process for coating finely divided material with titania and moisture insensitive zinc sulfide luminescent materials made therefrom
Inventor: KLINEDINST KEITH A
IPC: C23C16/40
Filed: 1991-06-06
Abstract: A method for coating finely divided material with titania is disclosed. The method involves the fluidization of the finely divided material in an inert carrier gas containing vaporized titanium isopropoxide.      The isothermal fluidized bed is kept at a temperature equal to or below approximately 300°C. The vaporized titanium isopropoxide reacts to form a coating of titania on the surfaces of the particles within the fluidized bed.      The greatest coating efficiency occurs when the fluidized bed is kept at approximately 300°C for approximately the first 10 minutes of the reaction and thereafter at approximated 250°C. The titania coating process is particularly useful for electroluminescent phosphors such as copper doped zinc sulfide phosphor. The titania coated electroluminescent phosphors are relatively insensitive to moisture. Lamps made from the coated electroluminescent phosphor are also relatively insensitive to moisture.

Patent CA-2046258-A1 (CA)
Inventor: THOMPSON TIMOTHY J
IPC: G06T1/00
Filed: 1991-07-04
Abstract: A flexible technique that is robust in the presence of noise and distortion is disclosed for locating and utilizing fiducial markings to locate predetermined areas within an image. Initially, a set of candidate markings is determined, one marking from within each of a plurality of predesignated areas of a scanned image. Thereafter, an estimate of a set of image distortion factors relative to an ideally registered image of the same type as the scanned image is derived. Predicted locations for the fiducial markings are derived using this estimated set of image distortion factors. If the difference in location between the actual location of any candidate marking and its predicted location is greater than a predetermined threshold, at least one such candidate is removed from the set of candidate markings. The estimation and removal processes are repeated, utilizing the new current set of candidate fiducial markings until all remaining candidate markings are within a predetermined distance of their predicted locations. Predetermined areas within the scanned image can thereafter be accurately located by combining the known location of the area within an ideal image with the final estimated set of image distortion factors. The predicted location may be further improved by using a weighted average of the ideal versus the actual fiducial marking differences, to account for local non-linear variations.

Title: Double-acting hydraulic piston
Inventor: VAUTOUR GILLES A
IPC: F16F9/48
Filed: 1991-09-17
Abstract: ABSTRACT     A double-acting hydraulic piston comprises a cylinder which has a first piston disposed therein in such a manner as to divide the cylinder into first and second fluid chambers.  The first piston is attached to a shaft which extends through one end of the cylinder and is reciprocable within the cylinder.  The first and second fluid chambers are connected to each other by a connecting mechanism so that fluid is able to pass from the first chamber to the second chamber, and visa versa, as the first piston is reciprocated within the cylinder.  A second piston is disposed within the connecting mechanism.   The second piston has a passage therethrough to allow for transfer of fluid from one fluid chamber to the other as the first piston is reciprocated within the cylinder.  The second piston moves in response to movements of the first piston, thereby effectively altering the capacity of the first and second fluid chambers to accommodate fluid as it is forced from one fluid chamber to the other by the movement of the first piston.  A mechanism is provided to compensate for the change in the length of the shaft as the first piston is reciprocated within the cylinder.  The double-acting hydraulic piston is operable in both the "push" and "pull" directions.

Title: Superconducting device having an extremely thin superconducting channel formed of oxide superconductor material and method for manufacturing the same
Inventor: NAKAMURA TAKAO
IPC: H01L39/14
Filed: 1991-09-27
Abstract: A superconducting device comprises a substrate, a projecting insulating region formed in a principal surface of the substrate, and a first thin film portion of an oxide superconductor formed on the projecting insulating region. Second and third thin film portions of an oxide superconductor are positioned at opposite sides of the projecting insulating region to be continuous to the first thin film portion, respectively, so that a superconducting current can flow through the first thin film portion between the second thin film portion and the third thin film portion. The second thin film portion and the third thin film portion has a thickness larger than that of the first thin film portion.  The projecting insulating region is formed of an oxide which is composed of the same constituent elements of the oxide superconductor but which has the oxygen content smaller than that of said oxide superconductor.     The superconducting device can be manufactured by forming on a surface of a substrate a compound oxide layer which is composed of the same constituent elements as those of an oxide superconductor but includes the oxygen amount less than that of the oxide superconductor, and which will be brought into an oxide superconductor when oxygen ions are injected, injecting oxygen ions into two separated portions of the compound oxide layer, so that the two separated portions of the compound oxide layer are converted into a pair of thick superconducting regions composed of the oxide superconductor, and heat-treating the layered structure in an oxygen atmosphere so that the oxygen is diffused into a portion of the compound oxide layer between the two separated portions of the compound oxide layer so as to constitute an extremely thin superconducting region.

IPC: F42B15/01
Filed: 1992-04-16
Abstract: OPTIMAL TELEVISION IMAGING SYSTEM FOR GUIDED MISSILE    ABSTRACT OF THE DISCLOSURE     A lens assembly (30) focusses an optical image of a field of view (20) forward of a guided missile (12) onto a photosensitive target layer (50)  of a television camera tube (52).   The target layer (50)  includes sublayers of zinc selenide  (ZnSe)  and cadmium telluride  (CdTe)/zinc telluride  (ZnTe),  and has a spectral sensitivity range which extends from approximately 400 to 900 nanometers.  A red  filter  (68)  is  provided  to  attenuate wavelengths shorter  than  600  nanometers  in  the  optical  image  to increase target contrast by reducing blue scattered light created by Rayleigh and aerosol scattering.  The lack of response of the camera tube (52) to wavelengths longer than 900  nanometers  further  increases  target  contrast  by reducing background radiation from soil and vegetation.  A motorized variable iris diaphragm (56) is provided in the lens assembly (30) to automatically adjust the intensity of the optical  image such that  the  television tube  (52) generates an electronic image with constant brightness although the brightness of the field of view (20) may vary considerably.   The diaphragm (56) has a high attenuation range on the order of 800:1 to accommodate a wide image brightness range.  A neutral density gradient filter (70) having an optical density which decreases radially from the center toward the periphery thereof is mounted adjacent to the iris diaphragm (56) to increase the dynamic range of the diaphragm assembly (56).
