Abstract:
In a marking device, by illuminating a laser beam onto an X-ray film which is a light-photosensitive heat-developing photosensitive material, an inner portion of a surface layer is melted, a cavity is formed, and a dot, which projects a surface out in a convex shape, is formed. At this time, an illumination time of the laser beam is controlled in order to control melting of the surface layer. In the marking device, when conveying of an X-ray film is stopped, oscillation of a laser oscillating tube is continued until a predetermined period of time elapses. When stoppage is for a short time, control is carried out such that marking can be started quickly.
Abstract:
An charged particle beam irradiation apparatus is provided which increases the width in a depth direction of a Bragg peak to be formed, by means of a simple construction. The charged particle beam irradiation apparatus includes a charged particle beam generation device and an irradiation field forming device. The charged particle beam generation device has a front accelerator and a synchrotron. An ion beam is guided to the irradiation field forming device from the synchrotron. The irradiation field forming device has a beam enlarging device, a Bragg peak enlarging device and a ridge filter. A pair of filter elements which constitute the Bragg peak enlarging device have a plurality of stick-shaped portions spaced apart from one another. The filter elements are disposed with their respective stick-shaped portions partly superposed to extend in mutually different directions. An ion beam that has passed through the Bragg peak enlarging device contains three ion beam components having different energies produced according to the difference between passed positions of each of the filter elements, whereby the width of a Bragg peak formed in the body of a patient is increased.
Abstract:
A method for fabricating an organic light-emitting device comprises in turn the steps of: providing a substrate; forming a first electrode corresponding to a light emission area; forming a stripe-shaped photoresist layer on the substrate having the first electrode wherein the photoresist layer is above the substrate having the first electrode; depositing an organic light-emitting medium layer on the first electrode in the exposed areas between the stripe-shaped photoresist layers to form a plurality of first electrode areas including the organic light-emitting medium layer on the first electrode; forming a second electrode on the organic light-emitting medium; forming a stress-relief layer on the second electrode wherein the stress-relief layer is a thin film of silicon oxynitride or polymer; and forming a passivation layer on the stress-relief layer wherein the passivation layer is an amorphous silicon, an inorganic nitride or an inorganic oxide.
