Title: Method of producing multidimensional lithographic separations free of moire interference
Inventor: GOGGINS TIMOTHY P
IPC: H04N1/23
Filed: 1995-04-28
Abstract: Multidimensional lithographs which impart the illusions of depth and/or motion to a viewer are prepared by constructing and sequencing a plurality of electronic pages, preferably four or more; rasterizing compressing and converting each page; interlacing the pages in a desired sequence; outputting the interlaced frames to an imaging device; and producing a lithographic separation from the imaging device. In the rasterization of each frame, nonbinary pixels are created that correspond to the resolution of the line count of the lenticular lens that will ultimately be applied to a print of the lithograph times the number of frames in the lithographic separation. The frames are compressed to an amount equal to the reciprocal of the number of frames from which the lithographic separation is prepared. In the converting step, the nonbinary pixels of the compressed frames are converted to individual color plates of binary pixels. The multidimensional lithographic separations are free of moire and screen interference.

Abstract: L'invention concerne un procédé de concentration de minerai, en particulier de minerai orifère. Ce procédé comprend des étapes consistant: à acheminer jusque dans la zone de traitement un courant de la boue à traiter contenant des grains du minerai de valeur ainsi que des particules de minerai stérile; à créer une couche piège dans la zone de traitement, laquelle est chargée de grains du minerai de valeur. Pendant le procédé de chargement, les propriétés de piégeage de la couche sont régénérées par la création d'une résistance hydraulique, inégale sur la longueur et la largeur du courant, au flux longitudinal du courant, et des tourbillons stationaires sont générés dans la partie inférieure du courant, l'axe de rotation des tourbillons étant à un angle donné par rapport au sens du flux. Les tourbillons agissent sur les particules dans la phase solide de la boue avec une vitesse orbitale supérieure à la vitesse de chute des grains dans le minerai de valeur. A mesure que le courant s'écoule dans la zone de traitement, il est incliné dans le sens transversal et un courant hélicoïdal est généré, l'axe de ce courant suivant la direction du courant incliné. Le dispositif de l'invention destiné à concentrer un minerai utile comprend une partie d'entrée ainsi qu'au moins une partie supplémentaire (1, 2 respectivement) jointes en séquence, la partie supplémentaire (2) étant inclinée par rapport à la partie d'entrée dans n'importe quelle direction, de manière que l'angle (.alpha.¿1?) entre les axes longitudinaux respectifs (a et b1) des deux parties se situe entre 0,5 et 45~, des riffles (10) se trouvant dans les structures (8) dans ladite partie supplémentaire (2) étant inclinés dans une direction opposée à la direction d'inclinaison de cette partie (2) par rapport à la partie d'entrée (1), et formant un angle (.beta.¿1?) avec les parois latérales (4) de la partie supplémentaire (2) de manière qu'elles forment un angle aigu (.gamma.¿1?) avec les riffles (9) dans la partie d'entrée (1).

Title: Production method of diffraction grating
Inventor: NISHII JUNJI
IPC: G02B6/124
Filed: 1996-11-13
Abstract: This invention provides a method of producing a diffraction grating of a spectroscope by applying light to a thin film of glass having characteristics such that a density change occurs with the change of a glass structure upon irradiation of light and volume expansion occurs irreversibly.      The method comprises applying light to a diffraction grating formation portion of a surface of the thin film by applying light through a phase mask or applying interference light, and causing the light irradiation portion of glass to expand and to thereby form the diffraction grating. Light to be applied is generally laser beams of ultraviolet rays, such as an excimer laser, a Nd-YAG laser or UV higher harmonics of a dye laser. A laser beam of a visible light region can be used, too. Preferably, a silica single crystal plate is used for the substrate of the thin film, and sputter vacuum deposition is used for forming the thin film. The glass composition whose volume expands upon irradiation of light is GeO2-SiO2 type glass having a GeO2 content of 20 to 95 mol%, but this composition is not particularly limitative, and any glass compositions can be used so long as they have a high volume expansion coefficient.

Title: Hybrid powertrain vehicle
Inventor: GRAY CHARLES L JR
IPC: B60K6/12
Filed: 1995-06-02
Abstract: Engine (1) output speed is controlled for optimum efficiency by adjustment of input speed of a continuously variable transmission (CVT) (3). Where power in excess of that provided by the engine (1) is required, additional power is input to the drive train from a fluidic motor (7) driven by fluid pressure stored in an accumulator (6). In driving conditions where the engine (1), operating at optimum efficiency produces power in excess of that demanded by the vehicle, the fluidic motor (7) is reversed for operation as a pump and excess engine power is utilized to drive the pump (7) and store energy in the accumulator (6) in the form of fluid pressure. A CPU (18) determines power output required of the engine (1) as a sum of that indicated by a sensor (14) which senses power demanded of the vehicle by a driver and an increment of power required to maintain the pressure of the accumulator (6) above a threshold amount.
