    摘要： With this radiation photographing apparatus, radiation image converting panels (or IPs) of the same size are used. X-rays shot through an X-ray tube are focussed to have a predetermined size by an X-ray diaphragm to expose a patient and to expose the IP with the penetrated X-rays. This IP is picked up from a feed magazine by a spot shot device, and is supported and set at a photographing position by a holder. The exposed IP is set in an image reading device. Only that area which has been exposed by X-rays is irradiated by a laser beam in the reading device. This area is scanned by the laser beam, and phosphorescence is emitted from the IP when it is irradiated and converted to an electric signal by a photodetector. This detection signal is sent to a image reproducing device to display the X-ray image.

    摘要： A magnetic recording method and apparatus is disclosed. The magnetic recording method includes forming a magnetic latent image on a recording medium with a scanning recording head so that the magnetic latent image has substantially the same width as that of the recording head, recording the magnetic latent image again with the recording head shifted from its first position by a predetermined width to cause overlapping to form a magnetic latent image with a predetermined width narrower than the width of the recording head and making the narrowed magnetic latent image visible.

    摘要： A magnetographic printing apparatus is disclosed which uses an electronically generated information stream to produce a visually readable image on a copy output medium. The high speed transfer of input information to the copy medium is accomplished by the direct writing of information pages with a magnetic write head less than the width of a page onto a magnetic buffer web. The latent magnetic image on the buffer web is transferred to a copy web wherein the pages are developed onto the copy medium at speeds approximating the direct writing time.

    摘要： A device for the magnetic storage of data which comprises a plate of a magnetizable material having a periodic structure of magnetic domains. Recording data occurs with an external magnetic field having a value at which 2 types of magnetic domains having different sizes can occur. The size of a magnetic domain can be varied by selective irradiation with light.

    摘要： A process for selectively affecting the magnetic properties in a magnetic particulate/resin material, such as an iron oxide-epoxy base coating as utilized on magnetic disks, disk pack assemblies and tapes, by creating an irreversible differential magnetic particle distribution in the surface of the material while maintaining the original surface topography, comprising the steps of exposing at least one preselected area of the surface for reaction with a reagent capable of converting the magnetic particulate material to a non-magnetic form, applying the reagent to the exposed areas, and removing the reagent from the preselected area of surface after a length of time sufficient to effect such conversion in the areas exposed, the reagent having the property of being substantially unreactive with the resin for the length of time of exposure.
