    摘要： A diode storage array, including a diode array on one face of a semiconductor wafer, an insulating layer overlying the opposite face of said wafer and a conductive layer overlying the insulating layer, is written upon by irradiating the conductive layer side of said wafer to induce charge storage in the insulating layer. The radiation may be high energy photons, a scanned electron beam or electrons from a photo-emitter. Readout is accomplished by irradiating the target with lower energy radiation to form electron-hole pairs in the wafer. The holes are selectively driven to the diode side of the wafer under the control of the stored charge where selected, reverse biased, diodes are discharged. Subsequent scanning of the diode array by an electron beam produces a variable output signal, indicative of the information stored. Since the charge on the insulating layer is not dissipated, the information can be read as often as desired.

    摘要： A TV camera tube suitable for the HN system comprising a glass faceplate covered by an n-type transparent electrode layer consisting of Nesa glass on which a thin p.sup.+ -type layer, a p-type layer and an n-type layer are deposited in succession to form a photoconductive layer. A blocking layer is deposited on the photoconductive layer to form a protected photoconductive target. A metal mesh covered by an insulating material and a collector electrode for collecting secondary electrons emitted from the target are arranged on the electron beam scanning side of the target.

    摘要： A multi-diode camera tube comprises means for receiving the radiation of the picture to be transmitted and emitting electrons according to the picture to be transmitted, these electrons being accelerated in an electrical field and impinge on a multi-diode plate to cause operation of the diodes in accordance with the picture content. The receiving means may be a photocathode or a secondary emission multi-channel plate depending on the radiation used for the picture.

    摘要： The invention relates to a method of forming an image of a sample in a transmission electron microscope equipped with a phase plate. Prior art use of such a phase plate can introduce artifacts in the form of ringing and a halo. These artifacts are caused by the abrupt changes in the Fourier domain due to the sharp edges of the phase plate in the diffraction plane. By moving the phase plate with respect to the non-diffraction beam (the diffraction pattern) while recording an image the sudden transition in the Fourier domain is changed to a more gradual transition, resulting in less artifacts.

    摘要： Bandwidth limitations in some video systems (e.g., those employing telephone transmission lines) prohibit the transmission of high-resolution video with the normal frame interval. One proposal for overcoming this is to extend the frame period. Although moving subjects cannot be televised in this way the proposal is quite adequate for transmitting documents. The convenient way to implement this proposal is to use a slow scan rate in the camera. However, conventional cameras are not made with sufficient storage duration to allow slow scan rates. The specification describes a video camera with a novel mode of operation to give extended storage capability.
