Abstract: A carriage transporting apparatus is capable of transporting one or more carriages along a track, substantially free of mechanical friction or magnetic drag, by magnetically supporting the carriages in a first direction and by stabilizing the position of the carriages in a second direction by passive means.

Abstract: An image capture panel includes a substrate layer of dielectric material having a top surface and a bottom surface. A plurality of sensors is arrayed in a matrix of rows and columns adjacent the top surface of the substrate layer. Each of the sensors has a switching device and a sensing element. A portion of the sensing element are really covers the switching device so as to be substantially coextensive therewith. Prefereably, the sensing element also extends over at least a part of the horizontal spacing and/or the vertical spacing which separates, respectively, each row of sensors and each column of sensors.

Abstract: A segmented article is disclosed which has selected Bragg reflection characteristics for a selected input wavelength. The article includes alternating sections of optical materials which are aligned and have refractive indexes different from adjacent sections to form at least one superperiod consisting of a plurality of segments such that each segment consists of a section of a first optical material and a section of a second optical material. At least one segment of the superperiod is different in optical path from another segment of the superperiod, and the interfaces between sections of the superperiod create backward travelling waves of complex amplitude at the selected input wavelength. The sequentially odd interfaces in the superperiod form a first set of interfaces and the sequentially even interfaces in the superperiod form a second set of interfaces.

Abstract: Segmented waveguides for wavelength conversion (e.g., waveguides comprising alternating sections of crystalline substrate having the formula K.sub.1-x Rb.sub.x TiOMO.sub.4 where x is from 0 to 1 and M is P or As and sections of substrate material in which cations of said substrate have been partially replaced) and devices and processes employing segmented waveguides for wavelength conversion are disclosed wherein a periodic structure along the waveguide provides a Bragg reflection having a wavelength essentially equal to the wavelength of the input wave used for wavelength conversion. Also disclosed is a process for preparing a channel waveguide for a wavelength conversion system wherein areas along a portion of a crystal substrate surface used for forming the desired channel are alternately masked and unmasked during cation replacement by immersion in a molten salt.

Abstract: Xeroprinting process involving imagewise exposing a photopolymer master, charging on a conductive support, toning with dry or liquid electrostatic toner, and transferring to another surface. Photopolymer systems comprising preferred combinations of polymeric binders, ethylenically unsaturated monomers. HABI initiators and chain transfer agents.

Abstract: In forming a latent magnetic image by imagewise demagnetization of a magnetized layer, less than the entire thickness of the exposed area is demagnetized so as to induce a magnetization of opposite polarity in the demagnetized area, thus reducing the net strength of the residual and induced magnetic fields within the exposed areas.
